摘要
基于城轨车辆牵引系统工作接地和保护接地耦合影响,分析了系统电磁干扰机理;建立了系统干扰简化计算模型,该模型具有结构简单、物理意义明确、同时适用于时域和频域分析等特点,可用于预估系统高频干扰特性。通过对实际城轨牵引逆变系统等效建模,并对系统高频干扰电流进行计算,结合实测验证了理论模型的准确性;最后,提出一种简单、高效的系统电磁干扰优化方法,试验结果验证了抑制方法的有效性。
Based on coupling effect of working grounding and protective earthing of traction system of urban rail vehicles,the electromagnetic interference mechanism of the system was analyzed,and the system simplified calculation model of the interference was put forward.The model had the advantages of simple structure and clear physical meaning,and was suitable for both time domain and frequency domain analysis,which could be used to estimate the system high frequency interference.Through the actual urban rail vehicles traction system equivalent modeling,high frequency interference current of the system was calculated,and the accuracy of the theoretical model was verified by experiments.Finally,a simple and efficient method of electromagnetic interference optimization was proposed,and the experimental results verified the effectiveness of the optimization method.
