| description | The paper provided a brief introduction to the characteristics and current applications of permanent magnet synchronous motors in the trains of Changsha metro line 5. It selected an experimental train that used a permanent magnet synchronous traction system on Changsha metro line 1 to conduct line simulation and on-site energy-saving tests for the traction system's energy consumption. Based on the analysis of the no-load energy consumption of trains using asynchronous traction systems on lines 1–4 and trains using permanent magnet synchronous traction systems on line 5 of Changsha metro, the efficiency and energy consumption with trains using asynchronous traction systems were compared and analyzed in detail. It was found that for the lines with regenerative energy absorption and utilization devices installed on the overhead contact network of the main track, excluding the impact of passenger capacity, the average energy saving rate of no-load trains on line 5 was 29.56% compared to line 1, line 3, and line 4, and 39.21% compared to line 2 without the regenerative energy absorption and utilization devices installed on the overhead contact network of the main track. Energy consumption of the train is an important part of the operation cost. The permanent magnet traction system has obvious energy-saving effect, which is consistent with the national requirements for the development of energy-saving, low-carbon economy. The application of permanent magnet traction system is helpful to reduce the operating cost of metro trains and realize the goal of rapid green transportation. |
