摘　　要：从分析高速客运专线牵引负荷特点入手,结合京津城际工程具体实践,分析了从高速牵引负荷引起的电压损失与系统短路容量的关系、电力系统的电压损失与系统短路容量的关系、高速牵引负荷引起的初步电压不平衡与系统短路容量的关系,得出电力系统短路容量与客运专线牵引变压器的电压损失无关、与电力系统电压损失成反比、与电压不平衡值成反比,从理论和远期规划上提出电力系统短路容量应满足4000MVA以上。Start from analysis of traction load characteristics of high speed passenger railway line, with reference of actual practice of Beijing-Tianjin passenger dedicated railway line, analyzes the relationship between voltage loss caused by high speed traction load and system short circuit capacitance, between voltage loss and system short circuit capacitance, between preliminary voltage unbalance caused by high speed traction load and system short circuit capacitance, obtains the conclusions that the power supply system short circuit capacitance has no relation with voltage loss of traction transformer of passenger dedicated railway line, and be in inverse ratio to voltage loss of power supply system and voltage unbalance value, puts forward that the short circuit capacitance of power supply system shall satisfy short circuit capacitance of 4 000 MVA in terms of theory and long term planning
