变速恒频发电机矢量控制系统仿真分析

Simulation of variable-speed-invariable-frequency generator based on vector control technology

在分析双馈式异步电机数学模型的基础上,利用Matlab/Simulink搭建了系统仿真模型.通过矢量控制技术进行解耦,使原动机转速不受电网频率的限制,采用SVPWM(空间矢量控制)方式对转子供电,实现了变速恒频发电系统.仿真结果证明了矢量解耦控制方法和SVPWM供电方法的有效性。

Based on the mathematical model of the wound-rotor asynchronous machine, a system of wound-rotor asynchronous machine has been founded by Matlab/Simulink. Vector control technology is adopted for decoupling, so that the speed of priming mover could shake off the frequency limit of power grid. SVPWM is adopted for feeding the wound-rotor. The reasonability and validity are testified by the simulation results.
