Abstract:
1. A wind farm control system including a plurality of wind turbine generators that generate electric power by rotation of rotors, in which the wind turbine generators are interconnected and are operated while power outputs thereof are limited in advance so as to be able to further supply electric power to a utility grid in response to a decrease in the frequency or voltage of the utility grid, the wind farm control system comprising: a measuring portion that measures, for each of the wind turbine generators, a physical quantity related to increase and decrease in the power output of the corresponding wind turbine generator; and a setting portion that sets, for each of the wind turbine generators, a limitation amount of the power output of the corresponding wind turbine generator on the basis of the physical quantity measured by the measuring portion, wherein the setting portion sets the limitation amount of the power output of each wind turbine generator so that the larger the physical quantity measured by the measuring portion, the larger the limitation amount of the power output, and the smaller the physical quantity measured by the measuring portion, the smaller the limitation amount of the power output.
