摘要
介绍了变速恒频机组的运行控制要求,重点研究了双馈发电机矢量控制方案下功率控制模式和转速控制模式的工作原理及能量转换关系,分析了两者动态特性差异产生的原因,所得结论为风电机组运行控制方案设计优化提供了参考。
Operating and contorl requirements of variable-speed constant-frequency（VSCF） wind turbine were introduced. Working principle and energy transforming relationship of power control mode and rotating-speed control mode of DFIG vector control strategy were studied in detail,and reason of dynamic characteristic difference between them was analyzed,which was helpful for wind turbine operating and control strategy optimizing and designing.
