Metro Power System Design And Simulation

With the development of the national economy and the increasing number of the city traffic line, the underground railway is getting more widely used in our country. Our country is in the significant time of development of urban rail transit at present. A number of large and medium-sized cities in China are carrying out the construction of urban rail transit.Based on the previous research achievement, design and simulation of urban rail transit power supply system are studied in this paper. And the case of Wuxi metro power supply project design and power supply simulation was completed.The subway power supply system design provides projects from many aspects such as main substation setting, medium-voltage power supply network setting, traction power supply system, stray current prevention, relay protection. Combined with Wuxi metro line1project, feasible power supply system design program is put forward.Urban rail traffic simulation includes train running and power supply simulation. On the basis of train running simulation theory and the locomotive parameters, circuit model can be set up. Then the software Open Track is used to do the train running simulation for Wuxi metro line1project. After that the equivalent electrical network structure model is built to calculate the parameters of the system by the software Open Power Net and get the main parameters of the simulation of traction power supply.
