摘要
介绍了背靠背双脉冲宽度调制(PWM)双馈型变频器和全功率变频器的基本工作原理,分析了风力发电系统中发电机启机、正常运行及电网异常时变频器的动作机制,为进一步研究更适用于风力发电系统的变频器提供参考。
The basic theories of the back-to-back dual-PWM double-feed frequency converter and the full power frequency converter were introduced.The action mechanism of the frequency converter during start-up and normally operation of the generator in wind power generation system and abnormal condition of the power grid was analyzed,which provides certain reference for further research on frequency converter more suitable for wind power generation system.
