摘　　要：地铁列车具有启动加速度高、运行速度快、准点率高且运力大等优点,其能耗问题一直是地铁运营的主要关注点之一。如何进一步提高地铁列车节能效率成为牵引系统设计研究的重点。相比传统异步牵引系统,传动效率高、过弯能力强的永磁直驱牵引系统是轨道交通牵引传动技术的发展方向之一。对照传统异步牵引系统性能指标,基于徐州地铁1号线列车确定永磁同步直驱牵引电机的设计选型,研制了一套永磁直驱牵引系统。针对永磁直驱牵引系统的特性,采用全速范围永磁同步电机无位置控制方法以及适用于永磁直驱系统的自适应黏着控制方法来完成牵引逆变器和永磁同步直驱电动机的实时控制。装车试验表明,永磁直驱牵引系统具有电机位置辨识稳定性好、响应迅速等优点,在低黏着轨面条件下列车牵引力发挥平稳且高效。能耗对比试验表明,永磁直驱牵引系统比异步牵引系统平均节能22.7%,可以获得显著的节能效果。结构紧凑及节能高效的永磁直驱牵引系统对促进轨道交通行业进一步发展具有积极意义。Metro trains have the advantages of high starting acceleration,high operating speed,punctuality and large carrying capacity,but energy consumption is also an important issue that needs close attention in metro operation.How to further improve the efficiency of energy conservation for metro trains has become a key point in the design of traction system.Compared with traditional asynchronous traction system,the direct-drive permanent magnet traction system with high driving efficiency and good corner-passing performance is one of the directions for the research and development of traction and transmission technology used in rail transit system.Benchmarking the performance indicators of traditional asynchronous traction system,a direct-drive permanent magnet traction system was developed based on the design and model selection of the direct-drive permanent magnet synchronous motor on the train of Xuzhou metro line 1.According to the characteristics of direct-drive permanent magnet traction system,a new full-speed range position sensorless control technique for permanent magnet synchronous motor and an adhesion control technique adapted for direct-drive permanent magnet system were used to realize real-time control of the traction inverter and direct-drive permanent magnet synchronous motor.The on-vehicle test showed that the direct-drive permanent magnet traction system has such advantages as stable motor position identification and fast response,and the traction force is stable and efficient with low adhesion on rail surface.The energy consumption comparison test showed that the direct-drive permanent magnet traction system was 22.7%higher than asynchronous traction system in terms of energy conservation,indicating significant energy saving performance.The direct-drive permanent magnet traction system,which is compact and energy efficient,has positive significance for promoting the further development of the rail transit industry.
