基于PSCAD双馈风力发电机励磁控制研究

在能源短缺和环境污染日益严重的今天，作为可再生绿色能源的风能的开发利用具有十分重要的意义。本文以交流励磁变速恒频风力发电系统的运行与控制为主题，进行了从理论到仿真的全面、深入的研究。对DFIG（双馈型感应发电机）的并网运行理论、最大风能追踪机理、DFIG有功无功功率解耦控制、双PWM型变换器特性等方面进行了细致的研究，获得了一些重要结论和具有创新意义的成果。

The Investigation of AC Excited Control for DFIG on PSCAD

It is of great significance to develop and utilize wind power, which is not only renewable but also without pollution when energy. source scarcity and environment pollution are getting more and more serious. With the operation and control of an AC excited VSCF wind power generation system as the research subject, this dissertation made complete study by simulation. The main research contents include： the operation theory of doubly-fed induction generator （DFIG）, the maxim wind power capture operation principle, decoupled control of DFIG active and reactive output power, gird-connection control and the study of dual PWM converter.
