内燃机车牵引系统矢量控制研究

Research on vector control of diesel locomotive traction system

依据内燃机车电传动系统特有的拓扑结构和控制特点,分析了矢量控制在内燃机车牵引系统上的应用,并从矢量控制策略和全速度范围调制策略两方面进行了说明,针对内燃机车电传动系统特点制定了相应的控制方式,通过计算机仿真和地面功率加载试验,验证了该矢量控制系统的性能。

Based on the unique topological structure and control characteristics of a diesel locomotive electric drive system,the paper analyzes the application of vector control in the diesel locomotive traction system and explains it from two aspects of the vector control strategy and the full speed range modulation strategy.Aiming at the features of the diesel locomotive electric drive system,a corresponding control method is established,and the performance of the vector control system is verified through the computer simulation and the ground power loading test.
