摘要

文章简要介绍了长沙市轨道交通5号线列车永磁同步电机的特点和应用现状，并选取长沙市轨道交通1号线1列采用永磁同步牵引系统的试验列车，进行牵引系统能耗的线路仿真及现场节能测试，并结合长沙市轨道交通1～4号线采用异步牵引系统的列车和5号线采用永磁同步牵引系统的列车空载能耗分析情况，针对效率和能耗与采用异步牵引系统的列车进行了详细的对比与分析，得出正线接触网安装有再生电能吸收利用装置的线路，排除列车载客影响，5号线空载列车能耗相比1号线、3号线、4号线空载列车平均能耗节能率达到29.56％，相比正线接触网未安装再生电能吸收利用装置的2号线，空载列车能耗节能率达到39.21％。列车能耗作为运营成本的重要组成部分，永磁牵引系统节能效果明显，与国家要求的节能低碳经济发展要求相吻合，永磁牵引系统的应用有利于降低地铁列车运营成本，并有助于实现快速绿色交通的目标。

Abstract

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.
