电牵引供电系统短路计算机辅助分析

CAA for Railway Traction Power Supply System Faults

根据电牵引供电系统故障的对称分量统一解析法及不对称短路计算的正序等效定则，形成一个通用等效复合序网，以运算曲线法，建立牵引供电系统中发生短路后任意时刻网络中任一处电气量的机辅分析计算的一套数学模型，并给出程序设计框图。

According to the unified analyses of railway traction power supply system faults by the method of symmetrical components and the positive sequence e- quivalent standing rule of unsymmetrical fault calculation,a generalized equiv- alent sequence network connection is established.Using the method of operat- ing curve,it is established that a set of CAA′s mathematic model of electrical values at a time after the occurrence of a fault wherever the railway traction power supply system. And the flowchart is given.
