Case Studies in Kazakhstan Intersolar Europe & Off-Grid Power Conference 2018

WINDKINETIC OFF-GRID POWER SYSTEMS AND MICROGRIDS

• Headquarters in Florence

• WindKinetic designs and produces innovative Renewable Energy

solutions for off-grid applications and microgrids (wind/solar/hydro

+ diesel back-up)

• We operate worldwide as technology suppliers, system integrators

and engineering consultants on EPC basis (Engineering,

Procurement and Construction)

• Our system are deployed in different fields and markets: NGOs,

Rural Electrification, mining industry, Oil&Gas Off- Shore,

Telemetry, disaster relief, civil use.

3



OUR MISSION

• Our mission is to bring green and reliable energy where

there is not or where it is unreliable.

• Our systems are entirely customized according to the

customer needs

• Our commitment to the Rural Electrification cause is

confirmed by our membership to the Alliance for Rural

Electrification.

CASE STUDY – 1

Standalone Wind/Solar Off-Grid System For

Off-shore Platform In The Caspian Sea (KZ)

5



OBJECTIVE

• Supply continuous and reliable energy to several VTMS (Vessels

Traffic Management System) with solar and wind energy only.

• Repeater stations are located off-shore in the Northern Caspian Sea

Region, in Kazakhstan.

6



THE CHALLENGE

• No downtime allowed

• 3 days of full autonomy in case of absence of sun and

wind

• No diesel back-up allowed by the customer

• Remote unmanned platform, no regular maintenance

possible

• Harsh marine environment

• Outside temperature from -40°C to +50°C

• Quick and easy servicing

7



OFF-SHORE PLATFORM

8



SYSTEM SPECIFICATIONS

• Wind and Solar power generating systems complement each

other, day/night

• 8 independent and redundant charging systems: 4 solar arrays

+ 4 wind turbines

• Customized wind turbines for low temperature marine

operations, entirely sealed, no need to grease ceramic bearings

• Data acquisition and remote monitoring of all the system

parameters, including the environmental ones

• Remote alarm notification system

• Redundant lithium iron phosphate (LiFePO4) battery bank

• Entire electrical system installed in a 10’ container, assembled

and tested in Italy before delivery

9



MARINE ENVIRONMENT

• The electrical system is entirely installed inside a IP60 container

• There isn’t any contact between sea air and electronics

10



MARINE ENVIRONMENT

• Cable entries are totally sealed

11



MARINE ENVIRONMENT

• The air conditioning system has two completely separated

air circuits:

– An external compartment, which is in contact with the

marine salty air.

– An internal compartment, which is in contact only with the

clean internal air

• The two circuit are coupled with a sealed heat exchanger

• The outside air and dust cannot enter inside the container

12



OUTSIDE TEMPERATURE: FROM -40°C TO +50°C

• The Container is fully customized with internal 10 cm thick

for thermal isolation

• 20 cm mineral whool floor insulation

• Low power consumption 24V air conditioning system to

keep the target internal temperature of 20-25°C during the

summer

• During winter time, the internal temperature will not drop

below -5°C

• The LiFePO4 battery technology allows operations at -5°C

13



REMOTE UNMANNED PLATFORM: NO REGULAR MAINTENANCE

• Full remote monitoring and control system. We monitor

over 70 parameters

• Historical data and trends allow the operators to identify faults

before they turn into critical issues

• Email and SMS alarms are triggered for several thresholds

• Full access to all the system settings from remote

• Turbines can be stopped from remote

SWITCHING FROM A REACTIVE TO A PROACTIVE MAINTENANCE APPROACH

14



REMOTE MONITORING: CLOUD

15



RACK

• All electronics are 19” rack mounted with disconnect plugs on

a rear panel. If any issue occurs and a replacement is needed,

the modules can be quickly hot-swapped.

16



CASE STUDY – 2

WindKinetic hybrid off-grid power trailer for a WiMax

emergency repeater in a mine in Aktogay, Kazakhstan

17



OBJECTIVE

• The trailer supplies continuous and reliable electrical energy to the

telecommunication and video-surveillance system in the Aktogay mine,

in an extremely challenging environment with temperatures from -40°C

to +50°C, dust, and mud.

• Windkinetic designed and engineered the system to operate in these

harsh conditions with no downtime.

18



RENEWABLE ENERGY TRAILER – SPECIFICATIONS

• The system consists of a customized off-road trailer with a

specific structure and a telescopic tower. The system

includes one Windkinetic Magellano 500 W wind turbine and

2 solar arrays (1000 W total).

• A diesel generator is installed as a back-up.

• The solar panels are mounted on the side and on the top of

the trailer structure, to be easily and safely oriented.

• The trailer chassis has 2 separated compartments. In the first

one there are the electronics, the battery bank and the telecom

devices. The genset, diesel heater and fuel tank are in the

second compartment.

19



RENEWABLE ENERGY TRAILER – SPECIFICATIONS

• The compartments are thermally controlled both at low

temperatures by the diesel heater and at high temperatures by

cooling fans.

• The entire system can be installed and be operational in less

than 1 hour.

• The evaluation of the state of health of the system is performed

by a remote monitoring and control system.

20



CONCLUSIONS

• We use our expertise on microgrids and off-grid technology

systems to deploy reliable projects for our customers

• We make plug and play solutions, which are already completely

operable, with no need for further integration by the customer

• We use top brand components with a minimum warranty of 5 years

• The power systems are fully assembled inside standard ISO

containers and tested in our facility in Italy

• Installation and commissioning is simplified and cost effective

• Maintenance and post-sales services are made easier by the use

of the embedded remote monitoring and control systems
