客运专线牵引供电系统电气特性的仿真研究

采用建模仿真的分析方法,以甬台温客运专线某一供电臂为原型,根据客运专线牵引供电系统的结构特点建立仿真模型。仿真分析了牵引网短路故障情况下,变电所测得的牵引网阻抗,并分析综合接地对牵引供电系统阻抗特性的影响;还仿真分析了在正常运行情况下,牵引网的电流分配关系。

Researches on Electrical Characteristics Simulation of Traction Power Supply System for Passenger Dedicated Lines

This paper adopts simulation method,referring to a feeding section of Ningbo-Taizhou-Wenzhou Line,simulation models are built according to design feature of traction power supply system.In case of short circuit for traction electric network,impedance of traction electric network measured in traction substation is shown,and the impact made by unified grounding system is analyzed in this paper.When traction electric network is under the condition of normal operation,the distribution of traction electric netwo...
