摘　　要：根据煤矿提升机的负载特性与运行特点,研究交流提升机交-直-交双边PWM变流器双馈调速系统在分别采用直接启动和单双馈混合启动两种不同模式条件下,变流器的额定功率容量差别。通过Matlab软件仿真对比,证实了煤矿提升机双馈调速系统采用单双馈混合启动模式的变流器额定功率容量,要比直接启动模式的变流器额定功率容量降低约38%。Based on the load features and operating characteristics of mine hoist, the rating capacity of converter power in AC - DC - AC dual PWM converter doubly fed speed control system was researched in the direct starting mode and in the single and double feed hybrid mode. According to Matlab simulation, it is confirmed that the converter power capacity of mine hoist doubly fed speed control system in the single and double feed hybrid mode is about 38% less than the power capacity in the direct starting mode.
