摘要
双馈电机变速恒频(VSCF)风力发电系统在变速恒频控制方面,主要是通过对转子绕组励磁电流的相位、幅值、相序及频率的调节来实现的。本文首先简要分析了双馈电机的运行原理,指出了其励磁控制方法,设计了以80C196MC单片机为基础励磁控制试验系统。最后探讨了动态转换控制技术思路,望能经此论述为此领域研究有所借鉴。
The VSCF wind power system for double-fed motor control is mainly realized by adjusting the phase,amplitude, phase sequence and frequency of the rotor winding excitation current in VSCF control. This paper first briefly analyzes the operation principle of the doubly-fed motor, points out its excitation control method, and designs an excitation control test system based on the 80 C196 MC microcontroller. Finally, the idea of dynamic conversion control technology is discussed. It is hoped that the research in this field can be used for reference.
