摘　　要：随着船舶吊舱技术以及永磁电机及其控制技术的发展,永磁同步电动机开始迅速应用于船舶吊舱电力推进系统中;针对船用电机的转速和转矩在过渡过程中波动很大的现象,引入了空间矢量脉宽调制方案,结合永磁同步电机数学模型及船桨模型,搭建了基于空间矢量脉宽调制策略的船用永磁同步电机仿真模型;仿真结果表明空间矢量脉宽调制方式可有效减小转矩的脉动,电机推进系统有良好的动态响应效果;为船舶电力推进系统的研究提供了新的思路。With the proposed ship pod concept and permanent magnet motor and control technology, permanent magnet synchronous mo- tor rapidly applied to ship power propulsion systems. In view of the phenomenon that the speed and torque of marine motor fluctuate in the course of the transition, space vector pulse width modulation scheme is introduced. Combined with the mathematical model of permanent magnet synchronous motor and hull--propeller model, simulation model of marine permanent magnet synchronous motor based on space vec- tor pulse width modulation strategy is built. The simulation results show that the space vector pulse width modulation method can effectively reduce the torque ripple, and the motor propulsion system has a good dynamic response effect. It provides a new way of thinking for the re- search of marine electric propulsion system.
