一种变速风力机全风速范围发电策略
Full Range Control Strategy of Variable-Speed Wind Turbines
摘要
Abstract
The turbine speed loop adjustment is a key link of the designing of the controller for the fixed pitch variable speed wind energy conversion system(WECS). Because of the strong nonlinear, big inerti-a and mechanical damping characteristics, it is difficult to design the controller of the wind power systems. A control strategy for variable-speed wind power conversion system is proposed, which can reach the maximum power point or keep the rotating speed constant when wind speed is under the rated value, and keep the rated output power above the rated wind speed. Then, a small signal model is presented, and a wind turbine speed loop regulator is designed. Finally, simulation system is built, and the results of the simulation and experiments show that the performance of the controller algorithm meet the requirements of WECS without wind measurement.关键词
