摘要
介绍了变频恒速双馈风力发电机的数学模型,分析了双馈风电机组转子侧变流器对发电机励磁的定子磁链定向的矢量控制策略,论述了采用定子磁场定向的矢量控制可以实现双馈风力发电机输出的有功功率和无功功率解耦。阐述了变速恒频双馈风电机组转子侧变流器励磁控制策略的仿真研究和试验波形。
The mathematical model of DFIG was presented,the direct stator-flux oriented ventor control strategy of rotor excitation converter was analyzed.The active power and the inactive power of DFIG stator can be decoupled with the directstator flux oriented ventor control strategy of rotor excitation converter were pointed out.The control strategy of rotor excitation converter simulation research and the waveform in experimentation were expounded.
