摘要

分析了船舶电力推进的特点和感应电机的数学模型，建立了以电压空间矢量控制理论为核心的感应电机矢量控制系统仿真模型，试验了带螺旋桨负载时，矢量控制的调速性能。仿真结果表明，感应电机矢量控制调速性能良好，适用于船舶电力推进系统。%This paper analyzes the characteristics of marine electric propulsion and the mathematical model of the induction motor,establishes a simulation model for the induction motor vector control system based on the voltage space vector control theory,and tests the speed control performance of vector control under propeller load.Simulation results show that the induction motor vector control has a good speed control performance and is suitable for marine electric propulsion systems.
