摘　　要：文章针对某型号55T交流传动内燃机车,利用电压空间矢量(SVPWM)灵活性的优势,采用恒压频比转速闭环的控制方法,在matlab/Simulink环境中建立了基于SVPWM的变频调速系统模型;仿真结果表明,与采用SPWM的变频调速系统相比,该系统的电压利用率高,使逆变器的输出电压空间矢量的运行轨迹更接近圆形,启动与运行性能良好,为实际控制系统设计和调试提供了理论依据。Aiming at a type of 55 T AC drive diesel locomotive,based on the advantage of voltage space vector(SVPWM)flexibility,using the constant voltage-to-frequency ratio rotation speed closed-loop control method,a model of frequency conversion speed regulating system based on SVPWM was established in the Matlab/Simulink environment,and the control method of.The results showed that the voltage utilization of the system is higher than that of SPWM,and the running trajectory of the output voltage space vector of the inverter is closer to the circle,and the starting and running performance are good,and provides a theoretical basis for the practical design and debugging of the control system.
