摘　　要：船舶电力推进系统的仿真建模技术研究多集中于数学模型,对设备模型实际物理结构的关注不多。针对这一现状,本文基于Modelica建立了船舶电力推进系统推进装置部分的仿真模型,直接面向物理结构提出了一种基于dq坐标等效电路的Modelica六相永磁同步电机模型。基于所建立的推进装置模型,进行了系统及仿真验证,结果表明所建立模型较好地模拟了电力推进系统的运行状态,适合于系统工程中系统级的仿真验证。所建立模型在实际工程中更加易于在不同领域的设计人员中流通使用。The research on the simulation modeling technology of the ship electric propulsion system mostly focused on the mathematical model,and did not pay much attention to the actual physical structure of the equipment model.In view of this situation,this paper establishes a simulation model of the propulsion part of the ship's electric propulsion system based on Modelica,and proposes a Modelica six-phase permanent magnet synchronous motor model based on the dq coordinate equivalent circuit directly facing the physical structure.Based on the established propulsion device model,the system and simulation verification are carried out.The results show that the established model can simulate the operation state of the electric propulsion system well,and is suitable for system-level simulation in systems engineering verify.The established model is easier to circulate and use among designers in different fields in actual engineering.
