1 PURPOSE
This project envisages the construction of a 26MW natural gas generation power plant in
the Republic of the Union of Myanmar. This power plant is conceived as a back-up to
increase the already existing power generation capacity that supplies the national grid in
the Yangon Region.
The power plant will be based on internal combustion engines technology. Although the
power plant will be managed as a single unit from a central control station, the design is
based on 26 gas gensets of 1MW, which can be also managed as independent generation
units.
The main advantage of this design is that using 1MW gensets the plant will have higher
degree of power availability in case of maintenance or reparations of the units than using
bigger sized gensets.
The plant has been designed foreseeing a future expansion with a second phase of
another 26 gensets. If this second phase is implemented the final capacity of the plant will
be of 52MW.
This new plant will be built adjacent to the existing Hlawga Gas Power Plant, which at
present day is composed by 3 gas turbines and a steam turbine, which have a total
available power capacity of 154,2MW. The gas supply for the new power plant will be
diverted from the MOGE gas regulation station that serves to the turbines.
The power plant is also adjacent to a power substation of YESB, where the turbines are
connected to Myanmar’s National Grid. The interconnection of the new power plant will
be made at the same busbar of 33kV as the turbines, using an available spare feeder.
Future expansion would require a second feeder in the same busbar.

2 GENERAL DESCRIPTION
The power plant is composed by two warehouse buildings. Each of them will house
13x1MW electrical generators.
Between these buildings, there will be a space where the transformers and a MV
switchboard box are located. These elements are used to step-up the power to 33kV.
Surrounding these buildings there will be a 7-metre wide road and then, further beyond
and parallel to the warehouses, there will be installed the air coolers for the cooling
system of the gensets.
On one side of the plot, perpendicular to the warehouses, there will be a gas regulation
and measurement station (GRMS) and, on the other side, next to the plot entrance, there
will be a building with offices, warehouse, the main control station and other facilities.
Close to the entrance, there will be two large transformers and also some MV protection
switchboards.
The size of the power plant will be of 107m (length) x64,8m (width).
General lay-out can be viewed in the plan No.:31.01The future expansion requires the
duplication of these elements, except the building of the offices, warehouse, and main
control station, which will be common to all the installation. View plan No.: 39-01.

3 CIVIL ENGINEERING
In the following chapter of this report is made the description of the Civil Engineering
works necessary to build the plant.
Related drawings 41-01 to 41-06 describe the necessary works for the urbanization of the
plant area, foundation, underground works, piping, slabs, etc..
Related drawings 42-01 to 42-17 describe the construction of the three main buildings;
the two engine rooms and the auxiliary services building.
In general terms this chapter describes the previous steps of the necessary works to
perform the plant construction; before strictly speaking, the generation plant equipment is
installed (generators, generator cooling system, electrical equipment and wiring, gas
installation, etc..)
Constructor should take in consideration that some works and installation not directly
described in this chapter should be performed in parallel to the underground civil works.
Notably underground installations like the buried grounding grid (view Plan 24-01) and
some buried water (view Plan 61-02 to 61-05) and gas (view Plan 62-03) pipes.
3.1 PRIOR DATA
The project will be on a horizontal area of levelled ground, which must be executed so
that it has volumetric stability without any settlement or shrinkage due to insufficient
compaction and without any increase in volume or expansivity. This levelled ground has
to be a regular surface in order to support the surface and the shallow and deep
foundations to avoid the undesired distribution of differential tensions and settlement
which may affect the layout of the facilities, the foundations of the buildings and the
foundations of the equipment. It must also be resistant to the erosion caused by water,
both the surface and underground water, and the levelled ground must prevent it from
sliding down the hillside.
The construction of the levelled ground is not part of this project and must be carried
out in accordance with the technical specifications of the project engineer and backed by
a local geotechnical study. The levelled ground’s design will also depend on the
construction techniques and available materials, as well as on the functional and structural
aspects and on the location’s height.

The levelled ground must ensure that the terrain has a bearing capacity of 1.5 kg/cm2
(0.15 MPa) on the base of the building’s footing and on the base of the shallow
foundations, as well as the ballast module indicated in the plans.
Regarding the plot where the road will be located, the levelled ground must be a category
E2, i.e. its compressibility module in the second bearing cycle obtained by a "Plate bearing
trial" must be > than 120 MPa. CBR>10.
Note: The design of civil engineering described in the following document was done
according these premises and with shallow foundations. After the visit of November 2012
to the site it was stated that the critical buildings required deep foundations (piles) in
order to avoid any collapse possibility in case of earthquake. A study was done to argue
this statement. This document, the related calculations and a foundation design with piles
are included as appendixes of this project. (View Appendix Civil Enginnering- Pile
design) Customer has decided not to follow this recommendation and thus a complete
design of the metallic structures based in these foundations was not done. The following
document describes a shallow foundation design.
3.2 FOUNDATIONS
Once the levelled ground has been approved, the necessary excavation will be made in
order to build the foundations for the buildings, whose support height is deeper. The
shafts for the foundations and the ditches for the centring beams will be excavated. It will
be checked that the terrain’s bearing capacity in the foundation base is 1.5 kg/cm2 (0.15
MPa). The ballast module will be 1,000 - 3,500 T/m3.
All the reinforced concrete elements will be on a base of blinding concrete that is 10 cm
thick.
The excavations will be in accordance with the instructions of the geotechnical study, so
that the embankments are stable. It will be possible to consider placing reinforcements
and shoring in the deep excavations.
The design of the foundations has been made in accordance with the Instruction on
Structural Concrete (EHE-08) and the Basic Documents on Structural Safety (DB-SE),
Structural Safety of Foundations (DB-SE-C), Structural Safety of Steel (DB-SR-A) and
Structural Safety on Building Actions (DB-SE-AE) of the Spanish Technical Building Code
(CTE).

3.2.1.1 Footings
The two warehouses where the generators and the ancillary services building are located
will have insulated rigid footings made with HA-20 reinforced concrete (f'c=200 with fck
resistance = 200 kp/cm²), whose depth will be in accordance with the plans in order to
prevent interferences.
The dimensions, reinforcement and characteristics of the concrete will be in accordance
with the plans.
The footings will be joined by the centring beams.
The footings will have anchor plates for the metal pillars, whose dimensions and
characteristics are detailed in the plans, and will be secured to the concrete with bolts.
The metal posts have to be placed before filling and tamping the excavations.
The separating walls between the 35 MVA transformers will be made of reinforced
concrete, whose dimensions will be in accordance with the plans (View plan No.: 41-06)
and their foundations will have continuous footing of 150 x 50 cm. of section. The
supporting height of these walls will be the same as that for the transformer tanks.
The walls have R120 fire resistance.
The air coolers will have a reinforced concrete footing on which concrete pillars will be
built in accordance with the plans (View plan No.: 41-05).
3.2.1.2 Concrete Slab Foundations
The foundations for the transformers, the main cell box, the line input cell room and the
GRMS will be made of concrete slabs, whose dimensions and depths will be in accordance
with the plans. (View plan No.: 41-05, 41-06.) Apart from the GRMS which will be
directly supported by the slab, the other elements will be supported by the
corresponding slabs through walls, thus providing tanks to collect the oil in the case of
transformers as well as pits in the cell boxes through which the installations will pass.
The generators will have a reinforced concrete bedplate which will serve as the
foundations and settlement, carrying out the function of seismic mass, thus isolating the
vibrations of the surroundings.

3.3 ELECTRICAL INSTALLATIONS AND PITS
In parallel to the generator rooms, along the lengthwise axis between them, a ditch will
be built for the electrical cables, with a minimum interior free height of 147 cm. Its
construction will base on reinforced concrete slabs and walls, with a thickness of 15 cm,
except in the cell box area and the prefabricated concrete caps. The cabling ditch will
have slopes towards the ends, where there will be a drainage system connected to the
rainwater sewage network to evacuate the water that may enter from outside.
Inside the generator warehouses, pits will be built for the electrical cabling under the
location of the control and power panels. Its construction will based on reinforced
concrete with anti-slip diamond plate caps with a thickness of 3 mm. They will have a
drainage system on the base through a PVC tube of Ø110 mm over a gravel bag.
The underground electrical installations go from these pits to the transformers and the
air coolers.
The plot’s other installations will be buried in ditches, whose design has been made in
accordance with the Spanish Technological Regulations (NTE) and Iberdrola’s specific
regulations in the case of the electrical pits.
The electrical pits, lighting and water pipes from the generator warehouses to the air
coolers will be made with HM-20 mass concrete to protect the pipes, and their support
height will be that stated in the development plans.
3.3.1 Electrical Pits
The electrical pits will be formed by corrugated polyethylene pipes whose diameters are
defined in the corresponding plans (View plans No.:41-02, 41-04 Detail Trenches 1
to 6), covered by an HM-20 mass concrete tray, whose dimensions and depth will
depend on the number of pipes that they have, and by a fill compacted to 100% of the S.P.
(standard Proctor) up to the level of the levelled ground. They will have boundary tapes
in the compacted fill.
The corrugated polyethylene pipes with a Ø200 mm connection between the electrical
conduits and the transformers will have a minimum turning radius of 40 cm, and those
which connect the transformers with the main cabling pit will have a minimum turning
radius of 72 cm.

There will be inspection hatches for the electrical pits, whose dimensions are specified in
the plans (View plans No.:41-02, 41-04 Detail Trench (electrical)) and they will be
made of prefabricated concrete with a prefabricated concrete cover with a metal frame.
These inspection hatches will have a drainage system on the base through a PVC tube of
Ø110 mm over a geotextile gravel bag.
3.3.2 Pits for the Lighting
The pits for the lighting will connect the planned lamppost system and will be formed by 2
corrugated polyethylene pipes, with a diameter of 90 mm, covered by an HM-20 mass
concrete tray, whose dimensions and depth are defined in the plans (View plans No.:41-
02, 41-04 Detail Trench 7), and by a fill compacted to 100% of the S.P. up to the level
of the levelled ground. They will have boundary tapes in the compacted fill.
There will be inspection hatches for the pits for the lighting, which will coincide with the
lampposts’ positions, their dimensions are specified in the plans (view plan 41-04 detail
Foundation with street lamp), and they will be made of prefabricated concrete with a
prefabricated concrete cover with a metal frame. These inspection hatches will have a
drainage system on the base through a PVC tube of Ø110 mm over a gravel bag.
3.3.3 Pits for Electricity, Data and Other Conduits
These pits are those which will connect the generator warehouses with the air coolers.
They will be formed by a row of conduits, covered by an HM-20 mass concrete tray,
whose dimensions and depth are defined in the plans (View plans No.:41-02, 41-04
detail Trench 8 to 11), and by a fill compacted to 100% of the S.P. up to the level of
the levelled ground. They will have boundary tapes in the compacted fill.
The development plans define the polyethylene pipes that will protect the water pipes,
which will be made of stainless steel. The depth has been established at 120 cm from the
axis of the pipes to the floor of the generator warehouses (height: +0.00).
3.3.4 Pits for Water Supply
A water supply network has been planned with water hydrants that help to clean the
roads. This network will go from the plot’s connection through the ancillary services
building and will be through a DN 50 mm polyethylene pipe.

The pits for the water supply network will be made with a sand base, which will have the
polyethylene pipe inserted, and a fill compacted to 100% of the S.P. up to the level of the
levelled ground. They will have boundary tapes in the compacted fill. The dimensions and
depth of the pits are defined in the plans. (View Plans 41-02, 41-04 details “Trench
for water pipe under the road”,”Trench for water pipe out of the road”)
3.3.5 Sewage Pits
To determine the width and depth of the pit, it is necessary to know the diameter of the
pipes, the geotechnical characteristics of the terrain and the possible mobile bearings that
can be transmitted to the subsoil, apart from the instructions from the site management.
To facilitate manipulation inside the pit, a minimum width has been defined for the lowest
point of the pit as the diameter of the tube plus 60 cm.
There will be a 10 cm-thick bed of granular materials to avoid contact with the sharp
elements that may deteriorate the pipe and, therefore, alter its sealing, resistance and
other characteristics. It will also be used to make a correct levelling of the terrain in
order to ensure the desired slope.
Once the pipe has been laid out, the pit will be filled with selected material compacted to
95% of the S.P. with a height of 30 cm over the line following the highest parts of the
pipe. The rest of the pit will be completed with a fill compacted to 100% of the S.P.
The compaction in any of the filling phases must be made with a lightweight tamper and
on both sides of the pipe, without compacting the central area that corresponds to the
pipe's projection.
The sewage network conduits with a diameter of 400 mm or less will be PVC SN4
compact pipes, while those with a diameter of more than 400 mm will be PVC SN8
compact pipes.
The inspection hatches and manholes of the sewage network will be prefabricated, except
the drains under the gutters and the grease separators.
There will be inspection hatches for the pits for the lighting, which will coincide with the
lampposts’ positions, their dimensions are specified in the plans (view Plan 41-02, 41-04
detail “Trench for sanitation water” & others), and they will be made of
prefabricated concrete with a prefabricated concrete cover with a metal frame. These

inspection hatches will have a drainage system on the base through a PVC tube of Ø110
mm over a gravel bag.
3.4 DRAINAGE SYSTEM
The drainage system has been designed to separate fecal waters, rain water and oily
water. The drains correspond to the items or surfaces where oil could have been
discharged.
3.4.1 Fecal Water Drainage System
Fecal waters to be drained come from the locker rooms and washrooms located in the
auxiliary services building. The water will flow to a septic tank equipped with a siphon
collection box at the beginning and a sampling collection tank at the end where a
discharge pipe is connected to an external channel with treated water. (view Plan 41-2,
41-04 detail “Siphonic Trench”)
3.4.2 Oily Water Drainage System
An oily water drainage system has been designed for the inside of each engine room. The
system is comprised of sumps that collect water originating from cleaning buildings, water
circuit spillage and engine base plate drains which is discharged via the sump drains. The
collection boxes are connected to each other via PVC pipes and drain to external oil
separator collection boxes where oil-free water goes to the rainwater drainage system.
Furthermore, rainwater that falls into the transformer basins will go to a collection box
controlled by a shutoff valve which will allow rainwater to be discharged or if there is an
oil spillage, it shall blocked until it can be removed by an authorized handler.
Collection boxes with shutoff valves are found in accessible locations in order to for
waste removal to be performed without having to be near restricted access areas located
near the transformers.
3.4.3 Rainwater Drainage System
Rainwater that falls upon the roofs of the buildings will be collected in pipes located
outside the building and transported by downpipes, attached to the facade, towards the
underground system.

The road and the transformers are located between two buildings; this area will have a
2% slope angle which leads towards concrete ditches. These ditches will have a
longitudinal slope which is higher than 0.5% and which will lead towards sumps connected
to the underground network.
Sump grating will be placed at engine room access points in order to avoid rainwater
from entering.
The central electrical cable trench will drain into the underground rainwater drainage
system.
The electricity collection boxes and gutters are designed with a drainage channel located
at the bottom, which is connected to a bed of gravel on ground-level..
The rainwater drainage system will discharge into the ground, in the sloppy area which in
turn discharges into the lake located on the west side of the lot.
3.4.3.1 Rainwater system sizing
Rainwater flow (Q) to be drained will be indicated in L/s and will depend on the following
factors:
The average run-off coefficient: Depends on the run-off coefficients for different types of
surfaces and areas considered. A coefficient of 0.85 is used for asphalt and concrete
pavements.
Rainfall intensity that corresponds to the maximum precipitation for a specific return
period and the length corresponding to the period of concentration time, which is the
necessary time needed to ensure that the maximum flow for discharge arrives to the
section considered.
A 100 year return period has been established since flooding could cause serious damage.
This means that the intensity is set at a 1.91 coefficient.
The period of concentration is estimated at a maximum of 10 minutes.
Rainfall intensity calculations are estimated at 120 mm/hour and the maximum average
intensity is 360 mm/hour for 10 minute intervals.
Surface area for wastewater areas at the point considered.

The rainwater drainage system is calculated based on severity patterns and a minimum
slope of 0.5%.
The drainage pipes need to be partially filled when in operation in order to ensure
adequate sewage network ventilation. The percentage of filling of the drainage pipes will
depend on the flow intake at each moment but the project has considered a filling level of
h=0.8Di, where Di corresponds to the inner diameter of the pipe.
Another determining factor for correct evacuation is the circulation speed. The minimum
speed has been set at 0.5 m/s which prevents sedimentation and a maximum speed of 2.5
m/s which prevents abrasion.
Full flow piping calculations were made based on the “Manning Formula” and the
“Thorman and Franke Table” was used to determine the relationship between, velocities,
flows and filling levels in partially filled circular conduits.
Manning´s roughness coefficient was considered at 0.008.
3.5 EXTERIOR FLOORING
Once the foundations had been executed and pipes buried, the next step is the
urbanisation of the plot’s exterior flooring. First the base of graded crushed aggregate will
be laid with the thickness and gradients as defined in the plans (view Plan 41-01, 41-05).
3.5.1 Roads
Given that at the time of the transport and installation of the engines and equipment,
heavy vehicles are going to circulate for a short period, a type of traffic D, medium light
T4.1, is established, corresponding to the movement of between 25 and 50 heavy
vehicles/day in low-traffic industrial areas.
25 cm. of graded crushed aggregate will be spread over the platform, with a density of not
less than 98% of the maximum reference obtained in the modified Proctor test, according
to UNE 103501.
The graded crushed aggregate to be used is a granular material, of continuous aggregate
grading consisting of totally crushed particles made from quarry stone or natural gravel.
Its cleaning coefficient according to annex C of UNE 146130 must be less than two. The
sand equivalent (Se) according to UNE-EN 933-8 must be greater than 30. According to

the two layers will be a 150 micra layer of polyethylene and a anti-puncture geo-fabric.
The mesh will be placed on the upper part of the sill, with a coating of at least 3 cm.
The concrete will have a mechanical trowelled finish sprinkled with non-slip grey quartz
aggregate.
3.5.3 Flooring of the Transformer Area y Front of the GRMS and
the auxiliary services building
The flooring around the transformers between the premises, the transformers and line
entry cell room, the ERM and the auxiliary services building, will consist of two layers
over the platform.

4 OPERATIONAL CONDITION AND TERMS
4.1 ELECTRICAL POWER GENERATION
4.1.1 Description of the power generation
The generators of the power plant are SFGM560 gas gensets of the Guascor-Dresser
Rand brand with a power capacity of 1MW.
These are 4-stroke Miller-cycle internal combustion engines with a 400Vac brushless
synchronous alternator coupled.
The power output of each genset is wired to his LV power switchboard. Each of these
switchboards will include his own synchronization and genset protection equipment. The
gensets will be connected and synchronized to Mains at this LV switchboard
independently. So they can be managed as independent generation units.
Each two gensets will be connected to a step-up transformer that will increase voltage
output to 33kV. These step-up transformers will be protected with MV switchboards
with overcurrent protections. The whole power output of the gensets will be conducted
to an outgoing switchgear. As total power output will be monitored at this point, the
central control system of the plant will be able to manage a “power plant” power setting,
deciding the power setting of each single gensets or eventually the disconnection of some
gensets if the power requirement is too low.
Isolation transformers have been foreseen at the outgoing of the power plant basically to
reduce the high short circuit current from Mains and isolate the power plant from the
grid. From the feeder a buried 33kV line will connect the substation with the plant. A
switchboard will protect this line at the power plant incoming. There’s foreseen a partial
redundancy of the common elements of the power plant (isolation transformers, outgoing
switchboards) to make sure that no failure of these elements would shut-down the whole
plant. Full redundancy is not possible due to lack of available interconnection feeders at
the substation.
Basically the working procedure will be that the gensets will synchronise to Mains and go
after frequency and voltage values of the Mains, controlling the active and reactive power
output with the set-up and adjustable values.

ROYAL GK PTE LTD

If any Mains electrical value (voltage, frequency, vector shift) would go beyond the
protection settings, the gensets protections would trip the LV genset switchboard and the
genset would stay in idle-running for a while, until Mains values would come back to
proper values.
During the idle-running, gensets cooling power supply should be connected to the gensets
power generation to allow a durable idle-running. This will be made turning manually a
switch in the control panel. A maximum 1Hr idle-running is foreseen. After this time
gensets will shut-down.
In case of genset shut-down is possible to restart the gensets without having power from
the grid, due to the use of batteries powered prelube, gas train and engine cranking
system.
If Mains condition returns to proper values the gensets may be re-synchronized to Mains
and continue exporting power to the grid.
4.1.2 Island mode procedure
Island mode is considered the working procedure in which gensets will control the
frequency and voltage of the grid instead of controlling the active and reactive power
supplied by them to the grid. This working procedure is used in the cases in which the
gensets are the main or sole suppliers of a factory, plant or grid.
In the case of the Hlawga power plant no island mode procedure is foreseen, although
design allows the gensets to work in this mode, controlling frequency and voltage of the
factory and making the load sharing between the single gensets of the plant.
An hypothetical upgrade to this working procedure would require a detailed study of the
load requirements of such island to check if the gensets would withstand the load
changes; it should be studied also the way in which such island would be made (which
switches have to be disconnected to feed the required loads), which kind of protections
would be available to avoid unexpected/unsynchronised connections with other gensets
and also should be agreed some kind of feedback/information system to inform to the
control system of an island/parallel to Mains situation. All these considerations are
external to the power plant and not included in the scope of this project.

4.1.3 Normal operation of the plant
Each genset will have its own power and control cabinet which is supplied with the
gensets scope of supply and, should be located in the engine room close to the gensets.
The documents IO-C-M-AP-00 and IO-G-M-AC-00 include a description of the
functionalities fulfilled by these cabinets.
These local control panels will be interconnected with a plant control panel which will
monitor all the local panels and also information coming from other elements of the plant
(MV substations, GMRS, fire detection system, etc..). This plant control panel will co-
ordinate the information of these different locals control systems.
Management of the gensets will be possible thus locally and remotely from the central
control system.
The engine-generator sets have two operation modes:
1) Automatic: A digital signal is generated for each engine-generator set from the main
control system in the plant. This digital signal has two position:
Remote start
Remote stop
Moreover, the main control system will send a signal with proper safety positions for
start-up. By means of this additional signal each generation engine will be enabled to
operate whenever required.
2) Manual: the operator will separately start or stop each engine-generator from the
control panel at man-machine terminal.
An automatic/manual selector switch will be provided for selection of operation
mode of each engine-generator set. When this selector switch is on manual position, it
will be possible stopping the engine-generator set on remote mode, but not starting it.
Likewise, if alternator protection devices detect any problem in waveform quality, the
related circuit breaker will be triggered. If alternator protection devices detect that the
electrical conditions in the system are normal, the alternator will be resynchronized and
the circuit breaker reset.

4.1.4 Start-up
Commonly, each generation set will be started in automatic mode by means of a remote
command from control system.
Each generation set will be started according to the following sequence
1) The system will verify whether the related engine is ready for operation or not. If not
ready, a warning signal will be activated. After started, the system will try to start the
next engine in the preset sequence.
2) The control system will proceed to perform the following tasks:
a) Start-up of pumps for cooling circuits.
b) Start-up of cooling fans in generation set room.
c) Verification that the related circuit breaker is open.
3) If the auxiliary equipment is properly operating and there is no problem, the control
system will proceed to start the generation set. Otherwise a signal alarm will be
activated and the engine will not be started.
4) From this moment the control system will proceed to synchronize the generation set
and couple it to the electric network.
4.1.5 Stop
Commonly every generation set is stopped in remote mode. The stop sequence for the
generation set and auxiliary equipment will be determined by the control system of each
generation set.
4.2 FIRE& GAS LEAK DETECTION
4.2.1 Operation
The activation signal of a fire sensor will have priority over the pre-alarm or a monitoring
signal failure.

The activation of one of these elements will cause the following (upon confirmation):
a) Local acoustic indication.
b) Message announced on the screen, indicating the date, time, location, nature of
the alarm and action message.
c) Printing of the nature of the alarm, type, date and time (requires external
printer).
d) Store the alarms until they are recognised and the system has been reset.
At any moment it will be possible to view the current status of the peripherals on the
screen, which ones are on alarm or have failed and print the information on a printer. It
will also be possible to pull up historical data of alarms, etc. and print them.
All of the detection circuits will be monitored for cable failures.
4.2.2 Fire protection system
4.2.2.1 Fire detection system
The fire detector signal is sent to the PLC. This activates the alarm sequence of each
genset and, at the same time, an alarm is send to the central control system. The central
control system starts the emergency stop protocol, as described below, and switch on
the general alarm light and horn located on the outside of the control room where is
located this central control system and SCADA.
4.2.2.2 Fire extinguisher system
Will be installed 5 and 10 Kg CO2 fire extinguishers in the transformers surroundings and
6 and 12 kg multipurpose dry powder fire extinguishers in the gensets building.
In the plan 35-01 are indicated the extinguishers needed according to standards; this
layout must be checked on field with the firefighter service.
The location of portable fire extinguishers will be readily visible and accessible; will be
located to points where more likely to start a fire and in evacuation routes. The path
from any point to the nearest fire extinguisher must be less than 15 m.

4.2.3 Control and signaling equipment (fire detection centre)
This element is the heart of the system where all of the incidents from the site are
collected and which, using the resident programme, will decide on the activation of
devices. The Centre will be analogical and smart with its own microprocessor, memory
and power supply and batteries.
The Centre will supervise each sensor and module of the smart loop individually, such
that the alarms, pre-alarms and malfunctions are announced independently for each
element in the smart loop. It will have the capacity for programmable outlets. It will be
located in a metal cupboard and will be equipped with optic indicators to view the status
of the panel. It will supply power to all of the sensors and modules connected to it. The
memory data, events and programming will be kept in a non volatile memory.
The control centre will allow the programming of its output devices (sirens and control
modules) in such a way that the facility can be evacuated in a logical manner following the
evacuation plan. To do this it is necessary for the sirens to be individually operable.
The Fire Detection Centre will be installed in a building with the following characteristics:
It shall have easy access, a simple architecture and be located in the vicinity of the
main access or of the one usually used by firemen.
It will be protected by sensors.
It shall be well lit and shall be protected from vibrations and overcurrents.
4.2.4 Loops and equipment of analogical systems
4.2.4.1 General.
Each sensor, manual alarm button and module shall have a unique address assigned to it.
This will be done manually. The location of the equipment in the loop will not be
conditioned by the address in the loop (e.g. sensors can be added to the loop using an
address that is not being used, without the need to re-programme the existing
equipment). Plan 27.02 shows the layout of the detection loop with the equipment
included in the loop. For the future expansion of the plant a second loop should be made.
Each detection loop will be a couple of braided shielded wires usually with a section of 1.5
mm, wired in open or closed loop and on which the analogical fire sensors, alarm buttons,

warning sirens and digital modules that are required for the monitoring and control
operations of the rest of the devices that make up the system (loudspeakers,
electromagnets, extinguishers, smoke control, HVAC control, etc.) are installed directly.
The capacity of the detection loop will be 198 analogical/programmable points of which
99 addresses are reserved for the sensors and the other 99 for buttons and modules.
The cable lines shall be laid in an independent pipe with an isolated wire for a nominal
voltage of 500V. The type of cable required will be:
o Name: Loop Cable
o Type of cable: Hose cable
o Number of wires: Couple of braided and shielded wires.
o Section: 1 to 2.5 mm2(standard = 1.5 mm2).
o Length of loop: Up to 3000 m.
1800 m. with 1.5 mm2section cable
3000m with 2.5 mm2 section cable
o Braids: 20 to 40 turns per metre.
o Shielding: Aluminium Shield with drain wire.
o Resistance: Max. 40 Ohm. for the whole loop.
o Capacity: Min. 0,5 f.
The diameter of the tube (D) will be sized in accordance with the number of wires
arranged inside it, thus:
No. of wires 2 4 6 8 10
METRIC 16 16 20 25 25
Similar alternatives that require more than 2 communication wires with the sensors will
not be acceptable.

Similar alternatives, in which the address of the equipment is automatic thus implying that
in possible extensions or modifications of the system or changes of the sensor re-
programming is required, will not be acceptable.
4.2.4.2 Smart analogical sensors.
All of the smart analogical sensors will be assembled on the same base so as to facilitate
the interchange of sensors of different types (if a different type of sensor were required).
Each sensor is assigned a unique address by means of a device which is simple to
understand and operate consisting of two rotating selectors numbered from 0 to 9 (not
binary type switches or using jumper breakers).
The procedure of automatic addressing according to its position on the loop was
discarded as when equipment is added in the near future, it would be necessary to re-
programme the existing addresses with the corresponding loss of flexibility and economic
cost.
Each sensor will have two LEDS that will make it possible to see the status of the sensor
from any position. The will flash each time of asking by the Detection Centre. From the
centre it will be possible to override the flashing of the sensors in idle status. If the sensor
is on alarm, these LED will be permanently lit up.
Each sensor will respond to the Centre with information and identification of its type
(multi criteria, optic or thermal). If there is a discrepancy about the information between
the sensor and the centre, a failure condition will appear. Each sensor will respond to the
Centre with analogical information related to its measurement of the fire phenomenon.
The values at which the sensor will go to pre-alarm and alarm will be programmable by
the user; these values can be changed manually by programming or automatically by the
centre based on the environment in which the sensor is located or by following the
hourly programme made by the system.

All of the sensors have a micro switch that can be activated by a magnet in order to carry
out a local operation test. This test must also be carried out automatically and
periodically from the centre.
The sensors will be wired with1 2 x 1.5 mm2 hose cable with a common section, braided
and shielded and shall provide both the power and communications required.
4.2.4.2.1 SMOKE SENSORS.
The smoke sensors shall respond by measuring the density of the smoke. Each element
can respond with different ranges of sensitivity that are adjustable.
The type of smoke sensor will be ionic when there are visible or invisible aerosols,
coming from all combustion and without the need for a rise in the temperature.
The characteristics of an ionic sensor make it more appropriate for the detection of fires
that spread quickly and which have combustion particles to the order of 0.01 to 0.3
micras.
The type of smoke sensor selected will be optic when there are visible aerosols, coming
from all combustion and without the need for a rise in the temperature.
The characteristics of an ionic sensor make it more appropriate for the detection of fires
that spread slowly and which have combustion particles to the order of 0.3 to 10
microns.
For highly sensitive applications where it is necessary to detect fires at a very early stage
the laser technology optic sensor will be used. This detects invisible combustion particles
(aerosols).
The infrared smoke sensor will be installed in those areas in which, due to the elevated
height of the ceiling, point smoke sensors are not appropriate.

4.2.4.2.2 MANUAL ALARM BUTTONS.
The manual buttons may be included in the smart detection loop as they are
programmable.
They should make it possible to voluntarily provoke and transmit a signal to the control
and signaling centre, in such a way that the area in which the button has been activated is
easily identifiable.
The buttons will be of the glass breaking type. The glass will be protected by a plastic
membrane to prevent its activation from being interrupted. Resettable buttons will not be
used, unless resetting involves the checking of the button by qualified personnel.
4.2.4.3 Control module.
These modules will be installed in the smart loop to make it possible to control the
auxiliary elements of the fire detection system such as: alarm loudspeakers, magnetic
retainers, fire dampers, extinguishing systems, etc. and to give relay signals to auxiliary
equipment.
The control module will provide supervision to the peripheral circuit which is controlled
by the module. It will have an LED indicator of its status.
It will be capable of working in 3 statuses:
As NA, CN relay outputs
As supervised 24 V outputs. In this case they will need 24 Vdc power additional
to the loop cable.
As evacuation loudspeaker output, which will require supply from the audio
amplifier.
4.2.4.4 Monitor Module.
These modules will be installed in the smart loop, to direct the digital inputs of the type
of those provided by conventional buttons, pressure switches, flow sensors, technical
signals, etc.
The monitor module will provide supervision to the peripheral circuit which is controlled
by the module. It will have an LED indicator of its status.

5 ENGINE AND GENERATOR ASSEMBLY
The generators of the power plant are SFGM560 gas gensets of the Guascor-Dresser
Rand brand with a power capacity of 1MW.
These are 4-stroke Miller-cycle internal combustion engines with a 400Vac brushless
synchronous alternator coupled.
Main features are listed below. For further information see technical instructions
The plans 31-01, 31-02 and 31-11 to 31-14 layout drawings indicate the location and
installation position of the gensets in the plant with their closer auxiliary equipment.
Sizes of the genset and installation instructions can be consulted in the “Genset
Installation Manual”.
The gensets will be supplied with two configurations; cable output left side of the
alternator and cable output right side of the alternator. (13 gensets with one
configuration and 13 with the other) Depending of the configuration, alternator cable
connection bars will be at one or other side of the alternator. The alternator will be
identified with a label of the suited cable output position
At the moment of the installation of the gensets, the installer should be careful to put
each genset in the place of the layout where his cable output position would be facing the
electrical trench.
Beside the genset in itself and the electrical installation necessary to export the generated
power there are some auxiliary installations which are essential to keep the gensets in
working order. These installations are described in the chapters 6 to 10 of this
specification. These mechanical auxiliary installations of the gensets are:
Engine fuel (natural gas) supply system.
Engine cooling system.
Engine lube oil system.
Engine Flue system.
Engine room ventilation system.

Each GenSet has a synchronous generator to 400V, which is connected to the low voltage
terminal of a power transformer with a double port in this side: each transformer is
connected with two generators.
During normal operation,the installation will export all generated energy
Gensets are equipped with alternators LSAC 502 TR L8 C6S/4: main features are listed
below. For further data view “Alternator Information” attached to the Genset Installation
Manual.

6 ENGINE FLUE SYSTEM
The function of this circuit is basically to conduct safely the exhaust gases from the engine
to the outside of the building. Exhaust gas flow from each genset is of 5170 kg/h at full
power with an estimated temperature of 496ºC. At partial load the exhaust temperature
may be over 550ºC
The pipes and elements of the circuit have been designed to allow the evacuation of these
exhaust gases keeping a maximum admissible exhaust backpressure of 450mm of water
column.
The document IT-C-A-40-001e of the genset installation manual describes the
requirements that a correct installation should fulfill.
Design of the engine flue system is described in the following drawings:
12-01: General Flow Diagram.
13-04: Exhaust Gases P&I diagram.
61-02 to 61-05: Lay out of pipes (exhaust circuit in pink color)
62-02: Lay-out of pipes genset area typical detail (the exhaust circuit is shown in
pink color)
63-21: Exhaust Pipes design.
51-01 to 51-06: Metallic structures for silencer and conduits support
The main elements of these circuits are:
U-3: the exhaust adapter commonly called “the trousers”, because it resembles
some trousers. It’s supplied with exhaust flexibles as loose item of the genset and
has to be installed at the engine exhaust connection.
U-4: the exhaust silencer. Also supplied as loose item of the genset. Regarding
engine flue circuit should be taken in consideration that there will be four “typical
layouts” with different pipeline designs. Type A (for genset 1), type B (for gensets
2 to 13), type C (for genset 14) and type D (for gensets 15 to 26).

6.1 EXHAUST SILENCER
The pipeline for exhaust evacuation must be provided with a silencer (U-4 in the
drawings), which has the task of reduce the noise produced by the engine toward levels
allowed in current Standards.
Description of the exhaust silencer supplied by Guascor is included in the genset
installation manual. (view IC-C-D-40-002e and IT-O-A-2-001110-05e).
The exhaust silencers require supporting structures. These supporting structures are
shown in the drawings 51-01 to 51-06.
6.2 EXHAUST CHIMNEY
Exhaust line ends with vertical pipe protected from rain with a gate.
A sampling module has to be placed, according to current environmental standards, after
the silencer.

7 ENGINE COOLING SYSTEM
The function of this system is to dissipate the heat generated by engines internal
combustion while gensets are running. Treated water is used as coolant fluid. The
SFGM560 gensets have a double cooling circuit. A main high temperature (HT) circuit is
responsible for cooling most engine components. A second circuit with lower
temperature (LT) is used to cool the air/fuel mixture and the oil cooler.
In the case of a SFGM560 genset at full load the HT circuit needs to dissipate 524kW of
heat power while the LT circuit needs to dissipate 179kW. Design temperature for these
circuits is 90ºC for the HT and 55ºC for the LT circuits.
The document IT-C-A-20-003e of the genset installation manual describes general
information about the cooling system for Guascor engines.
In this project cooling is done by means of air coolers. The air coolers are from the
double core type, which allow with the same cooler to dissipate energy from two
independent circuits of different temperature. Electrical pumps will impulse the water
from the engine to the air coolers and back. The cooling system includes thus two
independent closed circuits filled with pressurized water.
The cooling water has to comply the requirements of the product information IO-C-M-
20-001e (Cooling Water Quality and Treatment).
Design of the engine cooling system is described in the following drawings:
12-01: General Flow Diagram.
13-01: Engine Cooling System P&I diagram. Note that in this drawing is shown the
scope of the “Pump set” or “Pump kit” already supplied and assembled from
Guascor factory.

7.6 TESTING & INSPECTION
For the final acceptance of the in site assembly of pipelines installations, a hydraulic
pressure test is needed, considering each circuit as whole system. Test pressure will be
1.5 times the design pressure.
Before the hydrostatic test, equipment will be isolated in flanges using all the needed
elements for it(by-pass, closures, blind flanges, gaskets, etc..)
After pressure test, there will be a final cleaning of pipes, inside and outside of each one.
Once the hydrostatic test has finished, installation will be emptied in order to remove
metallic chips and dirt in line. Finally, before proceeding to final filling of each hydraulic
circuit, water is circulated by pumps, with basket filters placed at the entrance of each
equipment to protect them (one per pump, exchanger, genset, expansion tank, etc.).

8 ENGINE LUBE OIL SYSTEM
The function of this system is to ensure oil is available in all the lubricating circuits of the
engine, so that oil pressure quickly builds up a sufficient level for correct operations in
those applications where the engine is expected to develop its full power after the start
command.
For this application a single prelubrication process of 10 minutes is recommended prior
to any cold start operation. This operation is done with an electrical pump which is
supplied installed in an external oil tank of 300L. It’s a 24Vdc pump, thus it will be feed
from genset batteries allowing a start in a blackout condition of the plant. Once the
genset is started the mechanical oil pump of the genset will build up the oil pressure of
the engine.
Lube oil system includes four lines for connection of the engine and Lubricant oil tank.
The engine has three openings to connect the lubrication:
1. Filling
2. Pre-lubrication
3. Emptying
Connections are implemented under polyethylene ¾” pipes.
System includes a multifunctional pump with a set of valves defining the function to
perform. In normal operation the valves will allow the prelube operation, but the pump
may be used also to fill the engine with oil or empty it, being useful for the oil change
operations.
Technical instructions will be provided in further information for operation of this system.
The oil recommended for the lubrication is the Guascor Motoroil 3040 Plus Lube Oil for
Natural Gas-Fuelled and Ethanol engines.
Design of the oil prelube system is described in the following drawings:

8.1 BLOWBY GASES EXHAUSTING SYSTEM
In parallel to oil prelube system it should be also be taking in consideration the blowby
gases exhausting system, also known as crankcase breathing.
The “blowby gases” are the portion of fire gases that enter the engine oil casing through
the combustion chamber sealing segments. These gases increase the pressure of the
crankcase casing over the atmospheric pressure and thus should be removed. They have
to be also conducted outside the engine room to avoid risks of explosion or fire, the
clogging of the filters or the creation of a polluted environment. The document of the
genset installation manual IT-C-A-25-001e makes a description of this installation.
These drawings show the design of this blowby exhausting circuit.

9 ENGINE VENTILATION SYSTEM
9.1 DESCRIPTION OF THE ENGINE ROOM VENTILATION
The ventilation of the engine room should satisfy two fundamental functions:
Guarantee the environmental conditions, which permit the optimum performance
level of the engine and equipment.
Provide the most comfortable environmental conditions possible for the people
who have to work in the engine room.
In designing a ventilation system, the same importance should be given to the necessary
volume of air as to the flow direction.
The ventilation system must be able to provide sufficient combustion air and to remove
radiation heat from the rest of the facility.
Generally, the air flow direction in an engine room will match the following pattern
The entry of air in the engine room should be from the area furthest away from
any sources of heat.
The fresh air should be able to flow freely from the point of entry to the sources
of heat, in its circulation towards the point of exit.
The expulsion of hot air should be at a point directly above the most important
sources of heat, avoiding the intake of the exhaust gas.
Where the temperature of the engine room or, in particular, of the crankcase
gases return lines to the intake manifold is too low, the said lines must be heat-
insulated so as to prevent condensation in the said piping section.
In all cases, the hot air should be forced out of the engine room by means of an outlet
duct, without allowing it to mix with the fresh ventilation air.
The detailed information of the lay out and the ventilation system assembly is available in
the Annex (Ventilation System. Assembly Manual).

10 NATURAL GAS FUEL SUPPLY
10.1 GENERAL DESCRIPTION
The Natural Gas is distributed inside the power plant through a pipelines network.
In the regulation and metering station (R.M.S.), the natural gas is filtered and adjusted to
appropriate pressure level, in order to provide at the engines the power needed for
electrical generation.
The R.M.S. is provided with a non continuous gas analyzer whose function is to monitor
CH4, O2 and CO2 content in natural gas, and the communications output will be through
digital modbus and 4-20 mA signal.
Also, 2 electrovalves will be installed at R.M.S. outlet, which will be actuated in case of
serious alarm caused by loss of gas quality, gas leakage or fire. This electrovalves will be
supplied by 24Vdc batteries set located at the R.M.S. control panel to allow their control
also in situations of black-out or power supply shortages.
After the R.M.S., natural gas is sent into the two power generation engine rooms through
pipe internal network. Every engine is fed from a manifold located outside the engine
room,it means that there is one pipe entering the building for each engine.
Head losses in pipes are allowed while the pressure level at the inlet of the feeding ramps
is adequate in order to ensure proper running of the engine.

10.1.1 Internal connection.
The Service Pipes includes the whole of pipelines and fittings between the Service Key
(main supply valve), excluding this, and the Buildings Key (shut off valves at the entrance
of engine rooms facility), including these, in case of gas receiver installations supplied from
distribution pipe network.
10.1.2 Service pipes
10.1.2.1 General features
The Service Pipes of Natural Gas involves the different gas pipes with its fittings and
auxiliary items between the Regulating and Metering Station (R.M.S.) and the gas train of
every engine.
The R.M.S. is located in the south side of the Power Plant. It has two pipe outlets to
provide natural gas, one for each engine room.
TheService Pipes is formed by the following stretches:
1) R.M.S. output:Stretch comprised between R.M.S. and the engine rooms
area. Both pipes run parallel each other and in a buried stretch for crossing
the road. Once the road is crossed, the pipes get out to the surface and runs
through an aerial stretch, above a lintel, up to the engine rooms.
2) Engine rooms: The pipes are separated, each one toward their own engine
room with a symmetric route. The pipes goes down to the ground at the
entrance of the engine rooms, where there are shut off valves (building keys)
to lock the gas supply.The pipe distribution in the engine rooms is through
an aerial stretch, 3 m above the ground and supported in metallic structures
fixed in the pillars of the building.
3) Gas supply to engines:Stretch between the pipe distribution and the gas
train of the engines. At the inlet of the gas train, there are a shut off valve to
isolate the engine from the gas supply.

10.1.2.2 Calculations
10.1.2.2.1 INSIDE DIAMETER CALCULATION
The output pressure from the R.M.S. will be 3 bar g, and it will be the design pressure for
the gas distribution pipelines of the power plant.
The external gas service arrives at the power plant with a range between 10 and 40 bar g
so the design pressure will be 10 bar g because is the pressure that produces higher
velocities.
The procedure to calculate the inside diameter of the pipe is to establish an initial
diameter and apply the formula to determine the flow velocity and head loss to ensure
that the obtained values are according to the current Standards.
10.1.2.2.1.1 DESIGN ASSUMPTION
The design foundations are the following:
R.M.S. pressure output (bar g) ........................................................... 3
Max. Volumetric flow rate (Nm3/h):
Pipe distribution Engine Room 1 ........................................ 6.250,00
Pipe distribution Engine Room 2 ........................................ 6.250,00
Gas supply to engines (1-26) ........................................................ 481
Max. Design Velocity (m/s) ............................................................... 20
10.1.2.2.1.2 HEAD LOSS
The procedure to calculate the head loss in each stretch of the installation is through
applying the RENOUARD formula:

S: Corrected density
Q: Volumetric flow rate (Nm3/h)
D: Pipe inside diameter (mm)
L: Length.
10.1.2.2.1.3 VELOCITY

Qe: Yield strength of the pipe material (N/mm2).
e: Theoretical thickness of the pipe (mm).
d: Outside diameter of the pipe (mm).
F: Coefficient for calculations. Indicated in the Standard UNE 60305 = 0,4
C: Welding efficiency = 1
1) The minimum thickness of poliethylene pipes (HDPE) for gas are according to the
current standards so it is allowed to use in the specificated pressure range in the plant.
10.1.2.2.1.5 MEASUREMENT TABLE
The calculation results are shown in the following table.
As the table shows, the velocity values obtained in the calculations are under the
maximum velocity allowed by Standards for each stretch, 20 m/safter the R.M.S, and the
thickness of the selected pipes are above the minimum allowable thickness required by
the Standard.
The R.M.S. will adjust the pressure to 3 bar g, and thus this will be the nominal pressure
used for all gas pipelines installed in the plant.
The pipelines with tag “OTHER1, 2 or 3” correspond to the power plant main
connection of natural gas, before the R.M.S. For those pipelines the maximum velocity
allowed by the Standard is 30 m/s.
Gas supply at natural gas take-off will have a pressure between 10 and 40 bar g, and thus
design pressure for these pipelines will be 10 bar g as this is the pressure at which the
maximum flow rates are produced.

11.2.1 Smoke and heat point sensors
The number of smoke and heat point sensors is determined in accordance with the
stipulations of UNE Standard 23007/14, Annex A.
The sensors must be located such that their sensitive elements are less than 5% from the
top of the room. Due to the possible existence of a cold limit layer, the sensors shall not
be embedded in the ceiling. The heat sensors must be located below under the ceiling.
For point sensors the indication is that they must be distributed in such a way that no
point of the ceiling or of the roof is at a horizontal distance from the sensor greater than
the values of Dmax indicated in table A.1.

If there are unfavourable temperature gradients on the protected surface, the plume of
cloud rising from the fire can be suffocated and form a layer before reaching the ceiling. If
the height of this layer is foreseeable, sensors can be installed at the expected
stratification height as well as those sensors that are installed near the ceiling.
In narrow corridors and ceiling spaces that have a width of less than 3 metres, the
distances between sensors may be as follows:
- For heat sensors, up to 10m (5m for detection with coincidences or for
extinguishing systems);
- For smoke sensors, up to 15m (11m for detection with coincidences or
7.5m for extinguishing systems).
The horizontal distance between the sensor and the wall or the ceiling must not be
greater than half of the above mentioned distances.
The maximum area of authorized monitoring must not be greater than the added values
indicated in Table A.1.

their maximum area of coverage and the maximum lateral distance between sensors.
In the case of sloped ceilings, the lateral distance between lineal sensors will start to
count from the lintel where one device must be placed and measure between barriers
using it as a reference.
For buildings with ceiling with special forms such as saw tooth ceilings, a set of sensors
shall be installed for each tooth.
The sensor will be located at a distance from the ceiling between 0.3 and 0.8 m depending
on the height of the building, in order to avoid the thermal cushion of hot air.
11.2.3 Buttons
The distribution of buttons shall take into account the rules laid down in UNE-23007-14:
The buttons are located in such a way that it will not be necessary to move more
than 25 metres to reach one. In those premises in which the users may be
disabled, this distance should be reduced.
They are located at between 1.2 and 1.6 m from the floor.

11.2.4 Sound alarms
These elements are distributed in such a way that guarantees the minimum sound levels
expressed in UNE Standard 23007-14.
The sound level of the alarm shall be at least 65 dB(A) or 5 dB(A) above any
sound that is expected to last more than 30 s.
If the idea of the alarm is to wake people who are asleep, the minimum sound
level shall be 75 dB(A).
This minimum level must be guaranteed in all parts of the enclosure.
The sound level must not exceed 120 dB(A) at any point which is more than 1m
from the device.
The number of devices to be installed will be determined in accordance with the
following:
The number of sirens/bells must be sufficient to reach the above mentioned sound level.
The minimum number of devices will be two per building and one per fire sector.
In order to avoid excessive levels in some areas it is preferable to place more sirens with
less power.
The tone used by the sirens to warn of a fire must be exclusive for that purpose.

s: section of the cable in mm2.
V: voltage in volts.
11.2.6 Power and battery calculations
Power sources:
The UNE standards require the system to be equipped with a double power supply. This
is normally resolved by supplying the system directly from the general electrical grid of
the building and by using a group of batteries connected to a charger as standby. These
will be used if the main system fails.
Duration: according to UNE the emergency power supply in the case of failure shall
meet the requirements of the following table:
CONDITIONS STANDBY ALARM
Always 72 hours 30 min.
There is a local or remote monitoring
service with a commitment to repair in 24

Calculation of the capacity:
The following formula was used to calculate:
Cmin = (A1 x t1 + A2 x t2) ampshour
where: t1 and t2 are the operating times on idle and on alarm respectively.
A1 and A2 are the consumptions of the system in amps on standby and
alarm..
25% extra should be considered for the ageing of the batteries which means that the total
capacity will be: 1.25 x Cmin.
For the calculation of A1, we add the consumptions of all the elements that make up the
detection system and in order to determine A2, we calculate the consumption in alarm of
all the elements that intervene simultaneously.

11.3.2 Smart analogical sensors
11.3.2.1 Super flat Analogical Optic Smoke Sensor. NFX/ISO-OPT
The white coloured analogical photo electrical smoke sensor with isolator will have an
optic sensor camera and will use the dispersion of light as its main principle for detection.
It detects the presence of smoke through the light dispersed by the smoke particles inside
the camera of the sensor.
Associated with the photoelectrical sensor, is the recognition circuit that provides a
threshold for a predetermined level of smoke in the system initialisation circuit.
The direction of each sensor will be assigned by rotating switches. Each sensor reports its
direction, its type and its analogical type in order to give an idea of the measured value
and its status.
The sensor will have two LEDS, which make it possible to see its status from any
position. The LEDS will flash in normal operation and remain on in the case of an alarm.
As an option, flashing can be eliminated when the system is used in rooms.
It includes a micro switch that is activated by a magnet to check that the equipment alarm
works.
The sensors will be assembled on a common bayonet type base with an interlocking
device to prevent their accidental extraction. They may be assembled on a base with a
built in horn to provide a local acoustic indication.

11.3.4 Infrared barriers
11.3.4.1 Infrared Light reflection analogical smoke sensor
The linear optic beam reflector type analogical smoke sensorLPB700T is
compatible with all of the Notifier ID Seriescentres. Based on the principle of
darkening, it uses an infrared light beam. Optic beam smoke sensors are especially
appropriate for the protection of large areas, for example: industrial warehouses,
theatres, buildings with very high roofs where the installation of point sensors is not easy.
The LPB700Tsensor includes a transmitter and a receiver in the same unit and can
be connected directly to the analogical Notifier programmable loop without the need to
have an external power source, which is a considerable saving in the cost of installation as
it is only necessary to wire the emitter/receiver unit.
The infrared transmitter generates an invisible ray of light that towards the high
efficiency reflector and it returns the beam to the receiver of the LPB700Tsensor where
an analysis is made of the signal received. The change in the power of the signal received
determines the condition of the alarm.
The sensitivity of the sensors can be adjusted between 25% and 50% darkness. This
option makes it more adaptable to the different environments in which it is installed. As
well as the four fixed alarm thresholds, the sensor can be programmed to adjust
automatically to the environmental changes, within a known range of sensitivity, thus
reducing the number of possible unwanted alarms that could be generated because of
local activities in the protected area.
The LPB700T sensor is equipped with automatic dirt compensation, which means
that it will adapt its detection thresholds according to the signals received from the beam
caused by environmental contaminants. Once the sensor reaches its compensation limit,
the panel can identify and signal this condition.

12.4.2.5 Determination of step and touchvoltages
To determine fault and ground currents we should take into account the way in which
the neutral is connect to ground in MV section.
For networks with the neutral connected to ground, either rigid or through an
impedance, we should consider the applied contact or step voltage and the grounding
current (IE) which causes an increase of grounding system potential.
Step and touchvoltages are defined by the following equations:
L

Kp = 1/π ( 1/2h + 1/(D+N) + 1/2D + 1/3D +......+ 1/(N-1)D

Kc= 1/2π Ln(D2 /16hd) + 1/π Ln [(3/4) (5/6) (7/8).........(2N-3/2N-2)]
Where:
D = Spacing between parallel wires
h = Depth at which ground grid is buried
d = Diameter of ground grid wires
N = Maximum number of parallel wires in a direction for step voltage
N = Geometric average value of wires in both directions for contact voltage

13.3.1 Calculation of short-circuit current
13.3.1.1 Calculation of short-circuit current in generator panels
The maximum short-circuit current on busbars of generator panel depends on the short-
circuit current input by the grid through the transformer and the generator of this
transformer through the contiguous LV windings.

Data:
MV-LV winding
Ucc= 5,4 %
U20 = 400 V
Sn = 1250 kVA

Ucc= 9 %
U20 = 400 V
Sn = 1250 kVA
Engine-generator
Data: Pn = 1250 kVA
Xsubt = 13,2 %

13.3.1.2 Calculation of short-circuit current in Auxiliary Services
panel
The maximum short-circuit current on busbars of auxiliary services panel is determined
by T14 transformer.
Internal impedance of MV/LV
Data: %Ucc = 4 %
U20 = 400 V
Sn = 160 kVA
The maximum short-circuit current that could occur in auxiliary services line is 5,77 kA.
The switchgear provided in auxiliary services panel will have protection devices with a
breaking capacity above 5,77 kA.
13.3.2 Calculation of voltage drop
The rated voltage for the equipment to be installed in the plant is determined as a
function of supply voltage and considering a maximum voltage drop in internal circuits of
3% for lighting system and 5% for other equipment, according to the requirements of LV
regulations,
For plants directly supplied at high voltage by means of a separate distribution
transformer, the internal LV system will originate at the transformer outlet. In this case,
the maximum permissible voltage drop is 4,5% for lighting system and 6,5% for other
users.
13.3.2.1 Calculation of wire cross-section

substances are not handled. In this area are stored lubricant oils which are not dangerous.
The other warehouse is a storage building together at the oil storage, which keep the
other substances. This warehouse is protected with photoelectric smoke sensors.
The warehouses are located at the ending of the general services building next to the
parking.
The locations of the stores are identified in the plan No.: 31-01.1
14.4 AIR POLLUTION-EMISSION SOURCES
The power plant has 26 natural gas engines, each one with its own emission source of the
combustion gases.
The total thermal power associated with the 26 engines is higher than 50 MW
(approximately 67.26 MW, 2.6 MW each engine).
The total height of the smokestacks from the ground is 10.5 m. This height allows a good
dispersion of pollutants emitted.
The inside diameter of the smokestacks is 400 mm. All of the smokestacks have the same
dimensions.
The pollutants emitted into the atmosphere are NOx, CO and non-methane
hydrocarbons, (NMHC).
The emission control is done by measuring the gaseous pollutants in the sampling holes
above the silencers. View plan No.: 60-02.
The emissions balance emitted from smokestacks corrected to 5% O2 based NWMH C1,
are the following:

It’s possible to improve the noise level installing at the air ventilation inputs and outputs,
acoustic barriers that would improve the acoustic isolation. Ventilation has been designed
to allow this kind of improvement.
Picture 3. Noise distribution map with acoustic isolation at the air ventilation
system.
In this case the noise level reached in the surrounding industrial activities is lower than 45
dB (A). This level of noise is according with the current standards in noise matters for
industrial areas.
14.6 INDUSTRIAL SEWAGE WATER
The industrial sewage water associated with industrial activity carried out by power
generation of natural gas engines are the following:
o Network of sanitary sewage, from the existing toilets and showers. The sewage is
directed to a septic tank. It is a primary treatment unit of domestic sewage, inside is
performed the separation and physical-chemical transformation of solid matter
contained in those water. It is cleaned periodically by local operators.
o Network of rainwater from the downspouts from buildings. These waters do not
carry hazardous substances from the activity and go directly to the environment,
Hlawga Lake.

o Network of rainwater from collection bunds of transformers. They are guided to the
intermediate manholes for each of the transformers. The manhole has valves that are
always closed so in case of accidental spill it can keep the residue in a safe place
pending of its removal. The spill is pumped into containers and taken to a local
operator for appropriate treatment. In case of rain, the manhole is checked to ensure
that it does not have any residue, and then the valve can be opened to drive the
rainwater to the network.
o Network of oil water from spills in the engine rooms, after passing through the grease
decanter. The waters spill from engines are carried to grease decanters where the oil
is separated from water by density and then the clean water passes to final discharge.
Greases are collected periodically for treatment by local operators.
o In the plan No.: 41-02, you can see the different wastewater networks.

14.8 ENVIRONMENTAL MEASURES FOR THE SITE SOIL
Industrial activity due to the power generation of the plant through gas fuel engines is
placed on native soil that never has hosted any other previous activity.
The plant has been designed according to an engineering basis “100% Environmentally
Friendly”, with the most advanced techniques in environmental matters.
The location where takes place the industrial activity has a concrete pavement that
protects the ground from spills of hazardous substances, and it is provided with a
drainage pipelines to avoid the uncontrolled spills.
There are two points of risk for ground contamination, spills from engines and
transformers. The spill risk is taken under control through the following measures:
The rooms where are placed the engines has a closures such as decks and
walls, and the floor is provided with a drainage network to drive the spills toward
a grease decanter manhole, which separate the oil from the water. The water
treated can be discharged in the lake near the plant and the grease will be
collected through pumps for its future management. The engines will be assembled
over a foundation to protect the ground of the building from vibrations and also
the accidentally spills.
The transformers are placed inside concrete cubes with the purpose of
keeping any oil spill and avoid its dispersion.
These spills are driven to separation manholes, one for each transformer,
which are connected to another larger manhole by valves that are always closed.
In case of rain, the content of the manholes is checked to ensure that there
are not any spills from transformers, and then the valve can be opened to
discharge the water in the large manhole, which is connected with the rain water
network.
