变速恒频双馈风力发电机组运行在额定风速以下时,可以进行最大风能捕获,最大效率的利用风能;在额定风速以上,输出功率平稳,且传动系统具有良好的柔性。为了在实验室条件下研究变速恒频双馈风力发电电气控制技术,设计并实现了变速恒频双馈风力发电试验平台主控制系统,对主控制系统的硬件配置和软件结构以及系统所要实现的功能模块进行了详细的探讨。

Variable speed constant frequency wind power generation with doubly-fed inductor generation can obtain the maximal wind power tracking and utilize the wind energy to the maximum efficiency under rated wind speed. And above rated wind speed, the output power is calm, and the drive system has good flexibility as well. In order to study the technique of variable speed constant frequency wind power generation with doubly-fed inductor generator and related electrical control in laboratory environment, the main control system of variable speed constant frequency wind power generation with doubly-fed inductor generator experimental platform is designed and implemented, and the hardware configuration, system software structure and function module of the main control system are discussed in detail.
