A wind-power-station control apparatus is provided in a wind power station having a plurality of wind turbine generators. To reduce the electrical power supplied from the wind power station to the utility grid, the wind-power-station control apparatus performs, for a wind turbine generator whose actual output electrical power is small relative to the maximum electrical power that can be output, among the plurality of wind turbine generators, output-power reduction control for reducing the output power thereof and increasing the rotational speed of the rotor thereof. Thus, even when control for reducing the output power is performed for the wind turbine generator, it is possible to suppress waste of the wind energy received by the blades and to increase the total annual amount of generated electrical power.
