这个模型解释了DFIG WT的工作。 转子侧变流器模型化为受控电压源，忽略电网侧变流器，因为机器基本上由转子侧变流器控制，大部分有功和无功功率由机器提供。 矢量控制技术用于控制DFIG。 这不是一个完整的模型，而只是那些想了解双馈电机控制的人的起点指南。 机器的有功和无功功率由转子侧转换器调节。(this model explains the working of the DFIG WT. The rotor side converter is modelled as controlled voltage source and grid side converter is neglected as machine is basically controlled by the rotor side converter and most of the active and reactive power is supplied by the machine. The vector control technique is used for controlling the DFIG. This is not a full model but only a starting guide for those who want to learn about DFIG control. the active and reactive power of the machine are regulated by the rotor side converter.)
