| 摘 要： | 针对交流励磁双馈电机转子位置初始误差提出了一种补偿控制器。根据电网电压矢量控制时双馈电机数学模型,推导了定子开路稳态时转子电流与定子电压的关系,并基于此构建了转子位置初始误差的补偿控制器。对所提出的初始误差补偿原理进行了分析。另外,将该补偿控制器应用到风力发电系统实际并网控制过程,提出一种交流励磁双馈电机分段并网控制策略。设计了控制器,并在所搭建的变速恒频风力发电实验平台上作了相应的实验,结果证明了补偿控制器分段并网控制的有效性。

| Abstract: | In order to compensate initial error of position encoder used for ac excited DFIG(doubly fed induction generator),a controller was proposed based on the steady state relationship between rotor currents and stator voltages with open stator windings,which is derived according to the mathematical model of DFIG in the synchronous frame.The compensation principle was analyzed.A stagewise control strategy for grid connection was proposed by applying the compensate controller to DFIG wind power generation system.The overall controller was designed and implemented on the experimental platform.The results confirm the validity of the control strategy proposed. |
