摘要： A power system control apparatus which controls a power system electrically connected to 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. The power system control apparatus includes a voltage detector for detecting a voltage of the power system, a reactive power command value generation unit for generating a reactive power command value from a voltage detection value of the voltage detector, and a transmission unit for transmitting the reactive power command value to the wind power generation apparatus. Output fluctuation of the generator is suppressed, and reactive power according to the reactive power command value is transmitted from the wind power generation apparatus to the power system.
