客运专线10kV贯通线路接地方式及补偿方案的研究

摘要

In the power supply system of passenger-dedicated railways, earthing approach and capacity compensation option of power cables become the key technical problem since the capacity effect of the cables of through lines are complicated. The paper carried out a detailed calculation of the capacity current in the cables of through lines, incorporating the design of Jilin-Tumenjiang-Fenchun railway, studied the earthing approach and compensation option of through lines. On this basis, a software has been compiled by using VC++6. 0 to calculate the capacity current compensation for current through lines, to provide a powerful tool for future project design.%铁路客运专线电力供电系统,因贯通线路电缆的容性效应较复杂,使得贯通线路的系统接地方式及电容补偿方案成为电力工程设计中的一个关键技术难点.对贯通线路电缆的电容电流进行了详细计算,并结合吉图珲铁路的设计,就电缆贯通线路的系统接地方式及补偿方案进行了分析研究；在此基础上,应用VC++6.0编写了电力贯通线电容电流补偿计算软件,为以后工程设计提供高效的计算工具.
