摘要

摘要: 针对矿山电力牵引系统的发热问题，提出一种矿山电力牵引系统主动热均衡控制方法，即通过实时反馈系统的温度信号，完成对电动机定子电流幅值、驱动系统开关频率等参数的在线自调节；提出一种基于温度反馈的d，q轴电流矢量优化计算方法，使系统运行于全局效率最大的工作特性曲线；基于15 kW永磁同步电动机调速系统实验平台对矿山电力牵引系统主动热均衡控制方法进行了可行性验证。实验结果表明，该方法可在保证矿山电力牵引系统动态、稳态性能的同时，降低系统的热点峰值。

Abstract: An active thermal balance method of mine electric traction system was proposed to solve the system heating, which completed on-line self-adjustment of motor stator current amplitude and switching frequency of driving system by returning temperature signal of the electric traction system in real time. An optimized d,q axis current vector calculation method based on the temperature signal was proposed, which could make the electric traction system work at working characteristic curve with the maximum overall efficiency. The method has been verified by using 15 kW permanent magnet synchronous motor speed-adjusting system. The experimental result shows the method can ensure dynamic and stable performance of the mine electric traction system and decrease hotspot safety.
