级联式无刷双馈风力发电机的运行控制

为延长双馈电机的使用寿命,提高其可靠性,在分析级联式无刷双馈电机原理的基础上,通过转子和功率绕组、控制绕组之间的坐标变换,根据d-q双轴数学模型,推导出无刷双馈电机矢量解耦数学模型.仿真结果表明:同步角矢量解耦控制系统能够实现对电机转矩和磁通的完全解耦控制,空载并网控制调节过程快、精度高,并网过渡平稳,具有良好的控制性能,验证了无刷双馈电机矢量解耦控制的可行性和优越性.

Controlling of cascade brushless doubly-fed machine wind turbine operation

The attempt to extend the service life and improve its reliability in doubly-fed machine resulted in synchronized mathematical model through the winding coordinate transformation between rotor and power and control coordinates in d-q axis model,and based on the analysis on the operating principle of the cascade BDFM.The BDFM vector decoupling model was derived.The simulation results show that synchronous angle decoupling vector control system affords the full decoupling control of the motor torque and flux....
