Capacitor and Reactor Hybrid Connected Passive Filter Design Based on Matlab/Simulink

为了避免供电电源中存在的谐波影响电力设备型式试验结果,建立了基于Matlab/Simulink软件的滤波仿真模型,并利用其计算得出滤波装置各元器件的参数。在此基础上,利用三相电容器和多组单相电抗器设计出1台容抗混联的简易无源滤波器,滤除电源侧主要高次谐波电压。将该滤波器应用于1台永磁电机的试验,结果表明该装置能够有效滤除供电电源中的主要高次谐波。

In order to avoid the influence of harmonic in power supply on the test of electric power equipment, this paper establishes the simulation model of filter based on the software Matlab/Simulink, and the parameters of each element is calculated by means of this model on the basis of the above, a capacitor and reactor hybrid connected passive filter device is designed with three-phase capacitor and sets of reactors. With this filter, the main harmonic order of power supply can be filtered obviously. Finally, the filter is employed on the permanent motor testing, the results show that this device can filter the main harmonic effectively and its practicability can also be verified.
