四种海况下船舶推进电机建模与仿真

MODELING AND SIMULATION OF MARINE PROPULSION MOTOR UNDER FOUR SEA CONDITIONS

传统推进电机建模方法通过人为因素如突加突减负荷对推进电机进行仿真研究,忽略了实际海洋环境条件下对电力推进船舶航行的影响。基于PWM的电机建模方法结合MMG船舶运动模型并引入非人为因素如风、浪、流等海洋环境干扰力,搭建四种不同海况下船舶推进电机模型。对平静海况、极端海况和两种混合海况下的仿真结果进行分析,结果表明这种建模方法是合理有效并提供一种推进电机建模仿真的可行方法。

The traditional modeling methods of propulsion motor perform simulation research through the ship's human factors such as sudden increase and sharp reduction of propulsion motor load,which ignores the influence of different marine environmental conditions on the navigation of the electric propulsion ship.Based on the PWM motor modeling method,combined with MMG ship motion model,and by introducing non-human factors such as wind,wave and current and other interfering forces in marine environment,the ship propulsion motor model under four different sea conditions is built.The calm sea conditions,extreme sea conditions and the simulation results of two kinds of mixed sea state was analyzed.The results show that this modeling method is reasonable and effective,and provides a feasible propulsion motor modeling and simulation method.
