摘　　要：根据济钢中板厂粗轧机的参数建立了大功率交—直—交变频调速系统的矢量控制模型 ,并进行了各种参数的计算 ,对空间电压矢量 PWM(二电平 PWM和三电平 PWM)用于控制系统中进行了仿真研究。得到的仿真起动速度曲线具有谐波分量低、低频特性好、稳定性高等特点。The vector control model of high power AC-DC-AC variable frequency regulation sp eed system has been established based on the parameters of rough rolling mill of the middle plate plan t of Jigang and all parameters have been calculated, the space voltage vector (di-l evel and tri-level PWM) used as control system has been simulated. The simulat ion start speed curve has the features of lower harmonic component, better specific proporty for low frequency and higher stability etc.
