ADDITIONAL INFORMATION TO PROFORMA FOR PRIVATE WIND FARM

The proposed wind mill location is more than 410 m away from the existing wind mills.
The starting current of the proposed wind mill is limited by means of Thyristors provided in all three phases. The starting current of the mill shall be 600 amps, against the full load current of 1510 amps.
A capacitor bank of 800 KVAR is provided for the compensation of power factor, the designed operating power factor of the mill is 0.99. The capacitors are disconnected once the machine is off.
Necessary provision is made to cut out the wind mill automatically when the grid supply is failed.
Since the wind turbine generator is of induction type paralleling the generators with the grid will not cause fluctuations of disturbances to the grid and other consumers supplied by the grid due to paralleling of wind mill generator.
Since the import and export meter will be provided by us. We will pay the necessary supervisory charges.
Protection arrangement

The following protection arrangements have been proposed in the built-in microprocessor system of the wind mill.

(a) Phase fault

(b) Over voltage

(d) Frequency fault

(e) Grid drop

(f) Over protection

(g) Voltage fault

(h) Current fault

(i) Unsymmetrical voltage and current

(j) Over temperature

(k) Over load

(l) Earth leakage

FOR PRIVATE WIND FARM

Protection Arrangement

The following protection arrangement has been proposed in the built-in microprocessor system of the wind mill.

Phase fault
Over voltage
Under voltage
Frequency fault
Grid drop
Over protection
Voltage fault
Current fault

The details for the above faults have been enclosed for your reference.

The unsymmetrical current and voltage fault when the set parameter (i.e.10 %) exceed will be sensed by the zero voltage detecting transformer provided in the control circuit and the generator will be isolated from the grid.

In addition to the above protection system the temperature and mechanical operations will be monitored by microprocessor. The enclosed error chart is self explanatory to show how the faults are sensed by the microprocessor and protection have been affected to the wind mill as well as to the grid.

Capacitor

There are 800 KVAR capacitors are used for phase compensation. The designed power factor of the wind mill is 0.99.

The starting current of the wind mill is limited by means of Thyristors provided in all 3 phases.

The overload and earth leakage protection are provided by using static relays.

We hereby give our consent to meet the cost of power lines extended to our wind farm and necessary equipments for the meeting.

Topo sketch of the land and village map are enclosed.
