摘要:
地铁钢轨电位异常导致的钢轨电位限制装置频繁动作是目前地铁牵引回流系统运行过程普遍存在的问题。通过建立单边供电单车行驶的数学模型，结合电路中的叠加原理建立双边供电回流系统单车、多车行驶时的数学模型，在Matlab平台上对单、双边以及线路全程稳态运行的地铁牵引回流供电系统模型分别进行仿真，获取地铁正常运行下钢轨电位和杂散电流的分布曲线，通过仿真图形对比，分析钢轨电位和杂散电流的影响因素，为地铁合理运营与规划提供理论依据。
Abstract:
The frequent action of rail potential limiting devices caused by the potential abnormality of metro rail is presently a common problem in the operation of the traction power return system of the metro. A mathematical model of unilateral power supply single vehicle/train driving was first constructed, then a mathematical model of bilateral power supply return system single and multi vehicle driving was established based on the principle of superposition circuit. Simulations were conducted via the MATLAB platform, covering the single, bilateral and the whole subway line stable operation of the traction power return system models. The distribution curves of the rail potential and stray current of the metro power supply return system under the normal operation of the metro were obtained. A comparative analysis of the influential factors on the rail potential and stray current was performed to provide a theoretical basis for the reasonable operation and planning of the Metro.
