6. INTRODUCTION DESCRIPTION:
YEL WIND POWER project located in Jhimpir wind Corridor, which has a megawatt potential with average wind speeds over 7 meter per second , having capacity of 50 Mega Watt containing 20 turbines of 2.5 MW each .
MAIN PRINCIPLE
A wind turbine captures wind energy and then uses a generator to convert it in to electrical energy which is then supplied to national grid.

7. INTRODUCTION MAIN CONTRACTORS: DESCON & NORDEX PROJECT START DATE:
Project starting date was 14th of February 2015.
COD
Commercial Operation Date was 16th of September after RRT(reliability run test) conducted for one week.
TOC:
Taking over certificate(TOC) date is planned at first week of December.
MAXIMUM OUTPUT:
51.2 MW against 50 MW

15. WIND TURBINE GENERATORS COMPONENTS & ELECTRICITY PRODUCTION
The Wind Turbine mainly contains
Three Rotar blades connected by hub
Nacelle consists of drive train and generator with in it
Towers which bear weight of whole upper assembly

16. WIND TURBINE GENERATORS COMPONENTS & ELECTRICITY PRODUCTION
HOW IT WORKS
The wind is used to generate mechanical power or electricity.
Wind turbines convert the kinetic energy of the wind into mechanical power. This mechanical power is used by a generator to convert it in to electrical energy .Generator creates KV of voltage and passes it to convertor (which controls generator frequency) and GSU transformer.

17. ELECTRICITY COLLECTION SYSTEM
GSU (GENERATOR STEP UP) TRANSFORMER
The voltage by the each wind turbine generator is stepped up from 660 V to 22 KV by GSU transformer.
RMU(RING MAIN UNIT)
A Ring Main Unit (RMU) is a gas-insulated compact switchgear unit. It is also used for Power collection of whole wind farm by loop wise.
Loop A : WTG 1-5
Loop B : WTG 6-10
Loop C : WTG 11-15
Loop D : WTG 16-20

18. ELECTRICITY COLLECTION SYSTEM
CABLE COLLECTION SYSTEM
MV cables , earthing cables and fibre optic cables are brought to substation in cable trenches collectively by loop wise i.e. from loop A, loop B , loop C and loop D .

19. ELECTRICITY COLLECTION SYSTEM (SUBSTATION)
A substation is built to collect all the energy generated by the turbines and received through the MV cables . Substation consists of following elements:
Medium voltage system
High voltage system
Capacitors banks
Auxiliary services
Control, protection and metering system
Communication system
Fire protection and intruders protection systems

20. ELECTRICITY COLLECTION SYSTEM (SUBSTATION)
MEDIUM VOLTAGE SYSTEM
MV Switchgear connects different electrical nodes i.e connecting the power coming from collection system and transmit it to Power Transformers. It also provides electrical isolation and protection to the plant.

21. ELECTRICITY COLLECTION SYSTEM (SUBSTATION)
HIGH VOLTAGE SYSTEM
HV System consists of 132 KV switchgear and metering system . It finally transmit the power to national grid .

22. ELECTRICITY COLLECTION SYSTEM (SUBSTATION)
CAPACITORS BANKS
It is used for providing necessary reactive power to plant The demand of this reactive power is mainly originated from inductive load connected to the system.

23. ELECTRICITY COLLECTION SYSTEM (SUBSTATION)
AUXILIARY SERVICES
Batteries and EDG generators are used for power backup in case of power failure.

24. ELECTRICITY COLLECTION SYSTEM (SUBSTATION)
CONTROL, PROTECTION AND METERING SYSTEM
This system is used for controlling and protection of 132 KV switchgear . For overall controlling SCADA(Supervisory control and data acquisition) is used .

25. ELECTRICITY COLLECTION SYSTEM (SUBSTATION)
COMMUNICATION SYSTEM
These are telecom panels responsible for tele protection of lines.
