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。
In order to optimize the performance of the ship integrated electric propulsion system and reduce the risk of development, a propulsion system consisting of 12-phase synchronous motor, voltage inverter, propeller and ship load was established based on Mlablab-S im u link environment Part and system simulation model. The model was validated by the simulation of twelve phase synchronous motor propeller and ship load system with variable frequency and variable frequency control. In order to improve the performance of the ship integrated electric propulsion system, a model of 12-phase synchronous motor direct-axis air-gap flux linkage observer is derived, and a 12-phase vector control scheme of the synchronous motor is constructed. The simulation results show that the models are established correctly and the 12-phase synchronous motor vector control scheme can decouple the torque and flux linkage control, which can meet the dynamic performance requirements of ship electric propulsion system.
