摘要
双馈异步发电机采用交流励磁,利用矢量变换控制技术,综合改变双馈异步发电机转子励磁电流的相位和幅值,实现双馈异步发电机定子侧输出有功功率和无功功率的解耦控制。改变双馈异步发电机转子励磁电流的频率,可实现发电机的变速恒频运行。
Double-fed induction generator is excited by alternating current. Changing amplitude of the rotor current cooperating with phase by vector control technology, it can realize decoupled control of active power and reactive power of the stator. Doubly-fed induction generator can operate with variable-speed and constant-frequency by changing frequency of exciting current.
