This paper introduces traction energy flow, regeneration device, permanent magnet traction system and train operation, power supply simulation in urban rail transit traction system. In order to research the profit of permanent magnet synchronous traction system for the power supply system, taking a typical line as an example, based on permanent magnet synchronous traction system and induction traction system, make train operation simulation and power supply simulation respectively. Measured by a single train, permanent magnet synchronous traction system can reduce traction energy by about 20.9%, and measured by the power supply system, it can reduce 16.1% in condition on no traction substation with regeneration device, reduce 19.5% in condition on half of traction substations with regeneration device, reduce 20.3% in condition on all traction substations with regeneration device, and analyze their differences. The permanent magnet synchronous traction system can effectively reduce traction energy, save operating cost and reduce carbon emissions for urban rail transit in different condition.
