变速风力发电的最大风能捕获控制方法

摘要

有两种最大风能捕获控制策略:转速控制和功率控制.转速控制较直接、好理解,容易被做过电动机调速的人们接受.但是,大量实际系统都采用功率控制.分析了转速控制的问题及介绍功率控制的工作原理.最后给出一个实用的双馈风力发电机的控制框图,供参考.%There are two kinds of control strategies for capturing maximum wind power: speed control and power control. Speed control is more direct,easier to understand and to be accepted by the persons who familiar with variable speed motor drives. Unfortunately,most practice systems adopt power control. The problems of speed control were analyzed and the theory of power control was introduced. Finally,a practice control block diagram of doubly-fed wind generator was shown.
