Abstract:
1. A wind power generation apparatus having a wind turbine which receives wind and rotates, a generator which generates electric power by the rotating wind turbine, and a power converter which converts the electric power generated by the generator, wherein the wind power generation apparatus is electrically connected to a power system, and comprises: an interface device for receiving a first reactive power command value generated from a voltage detection value detected by a voltage detector provided for the power system; means for generating a second reactive power command value for suppression of voltage fluctuation by fluctuating output power of the generator; reactive power command value addition means for adding the first reactive power command value to the second reactive power command value; and means for outputting reactive power according to a third reactive power command value output by the reactive power command value addition means.
