摘要
本文描述了地下铁道直流牵引供电网发生短路时的稳态分析和计算的方法。建立的仿真分析模型考虑了上、下行各列电动车组的运行状态和牵引变电站的非线性外特性,也考虑了前级供电变压器短路压降和它的供电方式对其影响。短路稳态分析方法为地下铁道牵引供电网的保护特性选择和牵引变电站的容量和参数的设计提供了量值的依据。
This paper presents the steady-state analysis and the calculation method for a short cir-cuit in the subway traction power supply network. In building up the simulation analysis model,consideration is given to the following factors, the operating states of all out-bound and in-bound electrical multiple cars on line, the non-linearity of the output characteristics of the trac-tion power substation, the effect on the traction power supply voltage by the short circuit voltage drop of the forefront power supply transformers and the connection type. The short circuit steady-state analysis method provides basic data for the selection of power system protection char-acteristics and the design of the power rating and parameters of the traction power substation.
