单相并联型无源-有源混合滤波器的仿真研究

Simulation on single-phase shunt passive active hybrid filters

针对电气化铁道谐波、无功的综合治理要求和特点，利用一种单相并联型混合有源电力滤波器，将有源滤波器的输出电压反馈控制，保证了有源滤波器输出的基波电压为零，有效地减少了有源滤波器容量。通过分析混合滤波器谐波补偿原理，探讨系统控制电路。在ＭＡＴＬＡＢ／ＳＩＭＵＬＩＮＫ的仿真软件下，建立混合滤波器仿真模型，验证了方案的正确性和可行性。

A single phase shunt passive active filter is used to satisfy the requirements and features of the comprehensive compensation for harmonics and reactive power in electrified railways in this paper. The fundamental frequency voltage of APF is kept to zero to reduce its capacity effectively by voltage feedback of APF. The simulation model is presented with MATLAB/SIMULINK, and the simulation results show that the method is feasible and effective.
