摘　　要：为了优化舰船综合电力推进系统的性能,减少研制风险,基于M atlab-S im u link环境,建立了由十二相同步电机、电压型逆变器、螺旋桨及船舶负载组成的推进系统的各部分及系统的仿真模型。通过变压变频控制的十二相同步电动机带螺旋桨及船舶负载系统的仿真对模型进行了验证。为了提高舰船综合电力推进系统的性能,推导了十二相同步电动机直轴气隙磁链观测器的模型,籍此构建了十二相同步电动机矢量控制方案。仿真结果表明,各模型建立正确,十二相同步电动机矢量控制方案能够实现转矩与磁链控制解耦,能够满足舰船电力推进系统动态性能要求。An electrical propulsion system consisting of a 12 phase synchronous motor, a voltage source type inverter, a propeller and the ship was modeled using Matlab-Simulink blocks to optimize the integrated power system characteristics and reduce the research risks and costs. The 12 phase synchronous motor driven by a variable-voltage variable-frequency （VVVF） power supply drives the propeller and the ship. The electrical drive system performance was improved using a model of the direct-axis magnetizing flux linkage space-phasor to dev.elop a vector control scheme for the 12-phase synchronous motor, The simulations show that the torque and the direct-axis magnetizing flux linkage can be controlled separately, which is a requirement of the dynamic integrated power system for vector control scheme of the 12-phase synchronous motor.
