Abstract

A method of assembling a pitch assembly for use with a wind turbine. The wind turbine includes a rotor and a plurality of rotor blades coupled to the rotor. The method includes coupling a pitch drive system to at least one of the plurality of rotor blades for rotating the rotor blade about a pitch axis. At least one sensor is coupled in signal communication with the pitch drive system. The pitch drive system rotates the rotor blade when the sensor senses rotor overspeed.
