摘　　要：文章介绍电力推进船舶电力系统谐波产生的原因及其对于船舶其他电气设备的影响。通过EDSA软件对电力系统进行建模和分析,提出谐波抑制和消除方法。以实船电力系统为例,建立了该系统的仿真模型,对于采取谐波抑制措施前后的谐波含量进行对比分析。结果表明,该方法简单可靠且快速,对于船舶的后续设计有重要指导意义。This paper introduces the cause of power system harmonics generation in the electrical propulsion ships and the harmful effects on the other marine electrical equipments. Harmonics mitigation and cancellation are put forward through modeling and analysis of power system by EDSA software. Taking actual ship power system as example,it builds its simulation model,and eompares and analyzes harmonics THD results with and without harmonics mitigation. The results show that this method is simple, reliable and rapid. It provides significant guidance to following design of the ship.
