Electromagnetic Field of Catenary in Subway Traction Power Supply System
In order to provide theoretical basis and reference for engineering design and electromagnetic environment analysis of subway traction power supply system,the space distribution of electromagnetic field of catenary in subway traction power supply system was computed and simulated based on the finite element method.The visual analysis of electromagnetic field not only took into account the two typical power supply modes of DC750V contact rail power supply and DC1500V overhead catenary power supply,but also based on considered two different scenarios of train-running and train-free.Finally,the simulation results of catenary systems in Beijing and Guangzhou verified the feasibility and effectiveness of the proposed method.From the perspective of the electromagnetic environment,the two power supply modes were compared based on the simulation results.
