The technical characteristics and application status of permanent magnet synchronous traction system were expounded. Takes Changsha metro line 1 as an example, the energy consumption of permanent magnet synchronous traction system was simulated and tested in field, and a detailed efficiency and energy consumption analysis compared to asynchronous traction system was made. The comprehensive energy saving rate of permanent magnet traction system was pointed from 6.6% to 36.9%, which suggested that the application of permanent magnet synchronous traction system in rail transit should be promoted actively in China.
