| Summary: | 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. |
