Monitoring and control apparatus and method and wind power plant equipped with the same

摘要

It is an object to reduce influence on a utility grid by reducing a rapid change in active power, and to extend the life of a wind power plant while controlling active power output in response to a request from the utility grid. A monitoring and control apparatus applied to a wind power plant including a plurality of wind turbine generators includes an electric power control unit that controls the wind turbine generators so as to reduce output of the wind power plant in a stepwise manner, when an active power reduction request from a utility grid side is output.
