风力发电系统中最大功率点跟踪方法的综述

Review on the Method of Tracking the Maximum Power Point in Wind Power Generation System

为充分利用风能,需要捕获风电系统的最大功率点。由于风速的随机性与风电系统的非线性,最大功率点捕获控制比较困难,也是风力发电的热点问题之一。介绍了多种常用的最大功率跟踪方法的原理,说明了各种方法的优、缺点,指出了最大功率点跟踪方法的发展趋势,对最大功率点跟踪方法的选择和研究有一定的参考指导价值。

In order to utilize the wind power sufficiently,it is necessary to capture the maximum power point in wind power generation system.Due to the randomness of the wind speed and the nonlinearity of the wind power generation system,capturing the maximum power point is very difficult and is also one of the hot issues in wind power generation.In this paper,the principles of several common methods to track the maximum power point were presented;the advantages and disadvantages were discussed;the development trend of the method to track the maximum power point was pointed out.All these had referential and instructive values for the selection and investigation of the maximum power point tracking method.
