Abstract:

风轮大转动惯量导致最优转矩最大功率点追踪(maximumpowerpointtracking,MPPT)控制方法暂态时间过长,效率降低。通过研究风力发电系统(windturbinegeneratorsystem,WTGS)工作机理,对问题及原因作具体分析,并设计基于梯度估计的最优转矩补偿器,对电磁转矩给定值进行补偿,以减小大转动惯量对风轮转速变化的影响。通过建立兆瓦级双馈WTGS小信号模型及系统闭环传递函数,分析系统闭环极点、阶跃响应曲线及频率特性。小信号模型分析及仿真结果表明,改进后的方法具有良好的系统稳定性及动态特性,暂态过程时间小,兼有经典最优转矩法稳定性和叶尖速比法快速性等部分优点,风能转化率较高。
