Abstract:
1. A method for reactive power generation for a wind turbine generator, comprising: averaging measured reactive current for all or a subset of wind turbines within a wind farm or substation to generate a field-level average reactive power output signal; receiving a voltage command signal, the field-level average reactive power output signal, and the wind turbine's actual reactive power; generating a voltage trim value as a function of the field-level average reactive power output signal and the wind turbine's actual reactive power; adjusting the voltage command signal as a function of the voltage trim value; determining a reactive current command for the wind turbine generator in response to the adjusted voltage command signal; and transmitting the reactive current command to a controller of the wind turbine generator and generating a reactive power based on the reactive current command.
