对小型风力发电系统最大功率控制方法进行研究具有十分重要的意义。概述了小型风力发电系统的基本结构及工作原理,介绍了当前小型风力发电系统的功率调节方式以及最大功率的控制方法,并重点阐述了叶尖速比控制算法、信号反馈算法、爬山搜索算法以及三点比较法这四种功率控制方法,并对四种控制方法进行优缺点对比。最后提出我国当前在小型风电系统功率研究方面的不足以及今后的发展方向。
It is very important that studying the small wind power systems’ largest power strategy. The paper introduces the basic structure and operating principle of a small wind power generation system simply. Then it investigates the control strategy of the small wind power generation system and the accommodation mode. Moreover, TSR (Tip-Speed-Ratio) Control, PSF (Power Signal Feedback) Control, HCS (Hill-climb Searching) Control and TPC(Three Points Comparing) Control are mainly elaborated. At the same time, the respective characters were clarified. At last,future development tendency of the small wind power system has been proposed according to the current shortcoming of the small wind power systems on the control of power.
