- 摘要:
- 电力推进船舶的船—机—桨匹配分析中，仿真所需的模型复杂，工况多，耗时长。用于驱动船舶推进电机的二极管中点钳位(Neutral-Point Clamped，NPC)型三电平逆变器拓扑结构复杂，仿真中计算量大，严重拖慢了船舶电力推进系统整体的仿真速度。为解决此问题，在Matlab/Simulink软件中对一种船舶电力推进系统建模仿真，研究其特性，提出一种由受控电压源替代逆变器驱动十二相感应电机的仿真优化策略以缩短仿真所需时长。对比分析优化模型与原模型的仿真结果可知，优化模型启动与制动性能良好，可在电流、转矩、转速等外特性与原模型基本一致的前提下，将仿真耗时缩短数十倍。表明优化策略准确可行，符合复杂工况的仿真需求，可用于提高电力推进船舶的仿真效率，对同类调速系统有参考意义。
In the analysis of ship engine propeller matching of electric propulsion ship, the simulation needs complex models, many working conditions and long time-consuming. NPC (neutral point clamped) three-level inverter used to drive marine propulsion motor has complex topology and large amount of calculation in simulation, which seriously slows down the overall simulation speed of marine electric propulsion system. In order to solve this problem, a marine electric propulsion system is modeled and simulated in Matlab / Simulink software, its characteristics are studied, and a simulation optimization strategy of twelve-phase induction motor driven by controlled voltage source instead of inverter is proposed to shorten the simulation time. By comparing and analyzing the simulation results of the optimization model and the original model, it is concluded that the startup and braking performance of the optimization model is good, and the simulation time can be reduced by dozens of times on the premise that the external characteristics such as current, torque and speed are basically consistent with the original model. It shows that the optimization strategy is accurate and feasible, meets the simulation requirements of complex working conditions, can be used to improve the simulation efficiency of electric propulsion ships, and has reference significance for similar speed regulation systems.
