WINDMILL PITCH ANGLE CONTROLLER AND METHOD FOR CONTROLLING WINDMILL PITCH ANGLE

摘要

The object is to reduce aerodynamic load when a wind turbine is halted. When a wind turbine halt command is input, pitch angles of wind turbine blades 5-1, 5-2, and 5-3 are matched, and then the pitch angles of the wind turbine blades 5-1, 5-2, and 5-3 are moved to a feathering position.
