That is used generally in the world various metropolises. In order to guarantee the EMU (Electric Multiple Unit) of MRT system travels security. It must have reliable and the stable power supply system. But it need the various consideration during the system formulation period. For example, transformer capacity size of the traction supply substation, arrangement, the maximum load capacity…and so on. However these data must do with computer simulation and analysis. Then provides the analog data to do basis of as the plan, to guarantees the feasibility. This research mainly designs software of the MRT system power flow simulation analysis, is mainly take the movement equation as the foundation, the time by Time-based method proceed with simulations, and uses Discrete-event improvement time-gap, in each operation time obtains the train in the orbital route the electricity and the mechanical behavior, for example: Train in route running resistance, force of traction, speed, acceleration, power and so on, and transforms the train fictitious load and the hauling electric power transformer substation according to the route position into the direct-current equivalent circuit, from this makes the hauling electric power tidal current analysis, finally provides the related case and changes the train maximum speed with to reduce speed of parameter in order the acceleration, discusses its energy saving and influence.
