    摘要: A system and method of operating a wind farm, having multiple wind turbine generators, at high wind speeds is provided. Wind speeds at individual wind turbine generators are monitored and a signal is transmitted from the wind turbine generators to a wind farm control system based on the monitored wind speeds. Rate of change of collective power output of the wind farm is temporally monitored and is controlled by coordinating of operational states of the wind turbine generators based upon the signals transmitted by the one or more wind turbine generators, operating conditions of the wind turbine generators and the monitored rate of change of power output of the wind farm.

    摘要: A method for reducing load and providing yaw alignment in a wind turbine includes measuring displacements or moments resulting from asymmetric loads on the wind turbine. These measured displacements or moments are used to determine a pitch for each rotor blade to reduce or counter asymmetric rotor loading and a favorable yaw orientation to reduce pitch activity. Yaw alignment of the wind turbine is adjusted in accordance with the favorable yaw orientation and the pitch of each rotor blade is adjusted in accordance with the determined pitch to reduce or counter asymmetric rotor loading.
