船舶电力推进系统的计算机仿真研究

Computer simulation of marine electric propulsion system

传统船舶电力推进系统是将电力系统与推进系统分开设计的,因此集成度不高,从而导致系统运行性能较差,包括CPU工作频率、电流损耗以及螺旋桨旋转速度。针对上述问题,设计一个新的船舶电力推进系统,并与传统系统进行了计算机仿真研究。仿真结果显示:较传统船舶电力推进系统,本系统CPU实际工作频率提高0.23 GHz、电流损耗减少4.4 A以及螺旋桨旋转速度提高4.2 r/min,由此可知本系统性能要好于传统系统。

The traditional marine electric propulsion system is designed separately from the propulsion system, and its integration is not high, which results in poor performance of the system, including CPU operating frequency, current loss and propeller rotating speed. Aiming at the above problems, a new marine electric propulsion system is designed and simulated with the traditional system. The simulation results show that compared with the traditional marine electric propulsion system,the actual working frequency of the CPU of the system is increased by 0.23 GHz, the current loss is reduced by 4.4 A, and the rotating speed of the propeller is increased by 4.2 r/min, which shows that the performance of the system is better than that of the traditional system.
