摘要
Abstract
DC traction power supply system plays a key role in urban rail transit,and its safe and reliable operation is very important to the operation of the whole urban rail transit system.Firstly,this paper introduces the structure and function of subway traction power supply system,and establishes the simulation models of subway external AC power supply,rectifier unit and traction network.The simulation model is constructed according to the structure and parameters of the actual subway traction power supply system,and aims to study the short-circuit characteristics under different short-circuit conditions,including power outlet short-circuit,short-distance short-circuit and long-distance short-circuit.By evaluating the stability and reliability of power supply system under short circuit fault,some research results are obtained in this paper.These results provide a theoretical basis for selecting appropriate primary equipment for the subway power supply system,and help to ensure the stability and reliability of the urban rail transit power supply system.关键词
