Better energy efficiency

in the power grid

Cross-border energy trading and the incorporation power from

remote renewable power sources pose a serious challenge to existing

transmission networks.

Our main customers are Utilities, Industries, EPCs and the rail sector.

With the demand for electricity rising year on year and concern for

the environment bringing more renewable energy sources online, trans-

mission operators are under increasing pressure to enhance the flexibility

of their grids and to improve capacity and accommodate the demands

of deregulated power markets.

Growing electricity transmission.

concepts to meet individual needs

Air-insulated substationsAir-insulated switchgear (AIS) is the most commonly

used type of equipment for substations. It offers flexibil-

ity in terms of equipment configuration, as well as com-

paratively low installation costs. Substations using AIS

can be found in transmission networks of all sizes, all

over the world. ABB has been building and supplying

AIS equipment for nearly 100 years.

Gas insulated substationsGas insulated switchgear (GIS) incorporates all of the

same functional elements as air insulated switchgear,

but condenses them inside a sealed housing that

occupies one tenth of the space. GIS is ideal for use

in harsh environments, such as corrosive, salty air or

extreme temperatures. Its reduced footprint means that

GIS can be located in dense urban areas where space

is limited and aesthetic issues are important. ABB

pioneered the development of gas-insulated substa-

tions, delivering the worlds first GIS substation in 1967.

Since then, the company has delivered more than

10,000 high-voltage, gas-insulated switchgear bays.

Mobile substationsSubstation design has evolved to minimize the space

substations occupy and increase flexibility. Progress has

been such that it is now possible to build mobile sub-

stations on vehicles that can be moved from one loca-

tion to another. Such mobile substations are used by

utilities as a temporary solution during planned mainte-nance or restructuring of existing facilities or unplanned

outages.6

Our substation layout is

based on a customer

oriented modular con-

cept, using integrated

functional modules. The

pre-engineered and tech-

nically optimized modules

can be easily adapted toall individual requirements

and are equipped with

the most suitable com-

ponents for a particu-

lar function in respect of

design, technical char-

acteristics and reliability.

The pre-engineered mod-

ules guarantee an opti-

mized substation layout,a smooth project execu-

tion and minimal risk for

customers during project

realization and service.

Delivery of turnkey AIS and GIS

substations for utility, industrial and

railway applications.

Compact secondary substationsCompact secondary substations perform all the func-

tions of conventional secondary substations but, as

their name implies, their components are confined

within a very small space. These substations are typi-

cally used at the lower end of the medium-voltage

range (up to 24kV) in urban areas, where their housing

can be adapted to the local environment (to resemble

the surrounding building style, for example).

Distribution substationsPower systems must adapt to the needs of the com-

munities they serve. As communities grow and de-

mand for power rises, it becomes necessary to trans-

mit power to the more distant parts of the communities

at higher voltages. In such systems, distribution substa-

tions are used to step down the voltage and divide the

flow of electricity between the multiple outgoing lines of

the local distribution network..

Substation automation and protectionABBs world-class protection and control solutions

ensure reliable power transmission and distribution

through the smooth operation of its substations. ABBs

IEC 61850-enabled product portfolio provides open,

future-proof and flexible system architectures with

state-of-the-art performance. This, combined with long

experience in the field and the full scope of the compa-

nys service and support network, makes ABB a leader

in substation automation and protection.

with local standards

Substations are integral components of power supply networks. It is therefore absolutely essential

that the design criteria applied to the design of a substation be correlated with the corresponding

network parameters.

For network analysis and planning, ABB uses

state-of-the-art computer programs which

allow all aspects of system operation to be

examined in detail. Many years of cooperation

in the design of public and industrial power

networks has provided the company with a

wealth of experience in this field. This analytical

approach provides the basis for sound,

economically engineered solutions and a

secure, reliable power supply with minimal

environmental impact.
