摘要

滤波器的选型对变流器输出谐波的影响至关重要，文章以城轨再生制动能量回馈系统为研究对象，研究LCL滤波器与LC滤波器的滤波效果。同时，考虑牵引网络参数对城轨再生制动能量回馈装置输出谐波和谐振峰值的影响，采用一种基于比例环节的虚拟电阻串电容法用来消除谐振峰值，增强系统稳定性。研究结果表明，所采用的虚拟阻尼方法在工程应用上不失为一种可行的方法。

Abstract

The selection of filter is very important to the harmonic output of converter. Taking the regenerative braking energy feedback system of urban rail as the research object, the filtering effect of LCL filter and LC filter was studied. At the same time, considering the influence of traction network parameters on the output harmonic and resonance peak value of regenerative braking energy feedback device, a virtual resistance series capacitance method based on proportional link was adopted to eliminate the resonance peak value and enhance the system stability. The results showed that the virtual damping method is feasible in engineering application.
