摘要
客运铁路在采用电缆贯通线路提高供电可靠性的同时,不可避免地带来了电缆的容性效应问题[1]。本文在对铁路贯通电缆参数进行分析的基础上,介绍了一种仿真软件并建立了基于分布参数的电缆线路模型仿真方法,进行线路容性电流及单相接地故障的研究,对以后的铁路电力工程设计和计算有一定的指导意义。
Passenger transportation railway adopts power cable lines along the railway to improve the reliability of power supply, and the power cables also bring the ＂capacitance problem＂. Through the analysis of cable parameter, this paper introduces a kind of simulation software and builds a simulation model for cable lines based on distributed parameter, and also studies both capacitive current and single-phase earth-fault of cables. This paper has great signification for future engineering design and calculation of railway power supply.
