Wind turbine generator pitch control system

摘要: Wind energy is used to drive a wind turbine, which in turn connected an electrical generator produce power. The pitch angle of the turbine blades controlled closed loop manner maintain either constant speed for isolated power generating stations or when synchronized load, output shaft torque grid. Open acceleration and deceleration schedules are provided minimize blade stress variations during start up shutdown transients, limiting excursions as function velocity speed. may be implemented electronically by suitably programmed digital computer. gains speed, controls scheduled average optimize stability response. An anticipatory schedule responsive instantaneous added desired reference from transient resulting gusts.
