单周控制三相有源滤波器的矢量运算控制研究

Research on OCC three-phase APF of vector operation

针对基于单周控制的有源电力滤波器控制器参数设置复杂的问题,采用空间矢量算法和单周控制相结合的方法,将三相母线交流电压划分为6个区间,在每个区间内推出控制方程和控制电路并进行仿真研究。仿真结果表明,在电网电压不存在畸变的情况下,采用这种控制器的有源滤波器具有响应速度快、控制稳定性好、鲁棒性强等特点,而且控制器的实现简单方便。

Aiming at the complicated parameters setting for the active power filter based on a one-cycle control,the three-phase bus AC is divided as 6 zones by using the method of the space vector algorithm and OCC. A mathematic model in each zone is derived and the imitating research is also carried out. The simulation results show that the APF has rapid response, perfect stability, strong dynamic performance and easily realization for the controller.
