Voltage support allows
wind farm to remain
connected during a
fault.
•
Regulated voltage and power could allow increased
penetration of wind power into grid.
●
Gas turbine and wind farm do not have to be located in same
place.
-could offer support to offshore wind farms.

Model
●
Model uses dq axis reference frame.
Wind farm model stastistically scaled version of validated
single wind turbine model.
●
3-phase line to earth fault modeled between point J and the
grid.
●
Results
Normal operating conditions
- Voltage regulated to ± 2.5%
- Real power regulated to ± 5%
Fault conditions
- Wind farm remains connected.
