Method and system for operating a wind turbine generator

摘要

A wind turbine blade pitch control system (200) includes at least one blade pitch drive mechanism (130) coupled to a wind turbine blade (112). The system also includes at least one processor (202) coupled to the at least one blade pitch drive mechanism. The processor is programmed to increase a pitch angle of a first wind turbine blade (440) as the first wind turbine blade rotates through a first portion (414/438) of a 360° blade rotational path (302). Such pitch angle increase facilitates a reduction of acoustic emissions generated by a wind turbine generator (100). The processor also substantially simultaneously decreases a pitch angle of a second wind turbine blade (442) as the second wind turbine blade rotates through a second portion (418/426) of the 360° blade rotational path. Such pitch angle decrease facilitates an increase in power generated by the wind turbine generator.
