摘要:
［目的］相同动力配置下，永磁同步牵引系统的成本高于异步牵引系统，但永磁同步牵引系统能够有效降低列车运营能耗，因此有必要对永磁牵引技术在工程项目上的应用可行性进行分析。［方法］以南京地铁9号线为例，分别对永磁同步牵引系统和异步牵引系统的系统配置、运行能耗和维护成本进行了对比分析；提出将列车动力配置由4M2T(4动2拖)改为3M3T(3动3拖)的改进方案，对比分析了两种动力配置的列车牵引制动性能。［结果及结论］3M3T配置的永磁同步牵引系统能有效降低列车运营能耗，在牵引制动、故障运行性能和救援能力方面均能满足南京地铁9号线的运营要求，且其全寿命维护成本也相对较低。研究结果表明，在线路条件许可的条件下，可通过改变动力配置进行成本控制。

［Objective］ Under the same power configuration, the cost of a permanent magnet synchronous traction system is higher than that of an asynchronous traction system. However, the former can effectively reduce the operational consumption of trains. Therefore, it is necessary to analyze the feasibility of applying permanent magnet traction technology in engineering projects. ［Method］ Taking the Nanjing Metro Line 9 as an example, a comparative analysis is conducted on the system configuration, operational energy consumption, and maintenance cost of permanent magnet synchronous traction system and asynchronous traction system. An improvement proposal is presented to change the train power configuration from 4M2T (4 motor 2 trailer) to 3M3T (3 motor 3 trailer), and a comparative analysis of the traction and braking performance of the two power configurations is performed. ［Result & Conclusion］ The 3M3T configuration with a permanent magnet synchronous traction system can effectively reduce the operational energy consumption of trains. It meets the operational requirements of Nanjing Metro Line 9 in terms of traction braking, fault operation performance, and rescue capabilities. Moreover, the overall life-cycle maintenance cost of the 3M3T configuration is relatively low. The research results indicate that, under permissible line conditions, cost control can be achieved by modifying the power configuration.
