客运专线综合接地系统的仿真与研究

客运专线列车运行速度高、牵引电流大、短路电流大、行车密度高,导致钢轨电位急剧升高。为防止引起人身设备安全问题,客运专线设计引进了系统综合接地的概念和技术要求。本文结合理论计算模型研究和综合接地系统的仿真结果,对涉及人身安全的接地典型方案进行系统集成和评估,并提出了适宜于我国客运专线电气化铁道的综合接地系统。

Simulation and Study on Comprehensive Grounding System of Dedicated Passenger Line

High running speed, strong traction load current, high running density, high rail leakage resistance lead to steep rail electric potential rise in HSR. In order to avoid human and machine safety issues, the concept and the technique of integrated grounding system is introduced. With academic circuit model research and simulation results, representative integrated grounding project is assessed. The integrated grounding system fitted for civil passenger dedicated line is also presented in this paper.
