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.

A method of assembling a pitch assembly for use with a wind turbine including a rotor and a plurality of rotor blades coupled to the rotor, said method comprising:
- coupling a pitch drive system to at least one rotor blade of the plurality of rotor blades for rotating the rotor blade about a pitch axis;
- and,
- coupling at least one sensor in signal communication with the pitch drive system, wherein the pitch drive system rotates the rotor blade when the sensor senses rotor overspeed.
A pitch assembly for use with a wind turbine including a rotor and at least one rotor blade coupled to the rotor, said pitch assembly comprising:
- a pitch drive system coupled to the rotor blade for rotating the rotor blade about a pitch axis;
- and,
- at least one sensor mountable with respect to the rotor for sensing an overspeed of the rotor, said sensor is communicatively coupled to said pitch drive system, and said pitch drive system configured to rotate the rotor blade when said sensor senses rotor overspeed.
A wind turbine, comprising:
- a tower;
- a nacelle coupled to said tower;
- a rotor rotatably coupled to said nacelle;
- at least one blade coupled to said rotor and configured to rotate about a pitch axis;
- a pitch drive system coupled to said rotor blade for rotating said rotor blade about the pitch axis;
- and,
- at least one sensor mountable with respect to said rotor for sensing an overspeed of the rotor, said sensor communicatively coupled to said pitch drive system, and said pitch drive system configured to rotate the rotor blade when said sensor senses rotor overspeed.
A wind turbine in accordance with 19, wherein said sensor is configured to sense an acceleration of said rotor and to transmit a signal indicative of the sensed acceleration to said overspeed controller, said overspeed controller configured to receive the signal from said sensor and to identify a speed of said rotor based on the received signal.
