V/V接线变电所牵引侧复故障的一种分析计算

Analysis of Three-Phase Fault on the Tractive Side of V/V Connection Railway Traction Substation

本文将电牵引供电系统中V/V接线变电所当作具有不对称串联阻抗的网络。运用三相对称分量法,分析计算V/V接线变电所牵引侧复故障。对该故障的分析指出和提供了一种新方法,而且概念清晰,步骤简单。

This paper regards the V/V connection railway traction substation in the tractive power supply system as the network with unsymmetrical series impedances, analyses three -phase fault on the substation using the method of symmetricalcomponents . The new analysis is indicated and supplied for this fault. And the concept is clear. The steps are simple.
