Abstract
A wind turbine power generation facility includes: at least one wind turbine power generating apparatus; a lightning sensor for detecting or predicting occurrence of lightning in an installation area of the at least one wind turbine power generating apparatus; and a controller for switching an operation mode of the at least one wind turbine power generating apparatus to a lightning-protection mode in which a rotor rotation speed is lower than a rated rotation speed, on the basis of an output signal of the lightning sensor.
