Generation,Hazard and Control of Harmonic Waves in Ship Integrated Power System

舰船综合电力系统将传统的推进系统和电力系统合二为一,二者以电能的形式统一起来,其代表了舰船动力电力系统发展的新方向,但与此同时带来的是大量增加的用电负载,其中包含大量非线性和电力电子设备,将引入谐波污染,而谐波是影响舰船综合电力系统电能质量的主要问题之一。为此,首先分析了谐波产生的主要原因,进而阐明谐波可能带来的危害,最后总结了现阶段常用的谐波治理方法,主要有源端抑制和系统补偿,并结合案例的仿真分析、工程应用验证了主要谐波治理方法的有效性,为舰船综合电力系统的谐波治理提供参考。

The ship integrated power system combines the conventional propulsion system and power system in the form of electrical energy,representing the development of the ship power system.However,the harmonic wave,one of the main issues affecting the power quality of the ship integrated power system,will be generated by large amount of non-linear and power-electronic devices due to the greatly increasing electrical load on board.The reasons for the generation of the harmonic waves are firstly analyzed,and the possible hazards caused by the harmonic waves are then presented.Finally,several commonly used harmonic wave control methods are summarized,mainly including source suppression and system compensation.Simulation results and engineering application cases are presented to demonstrate the effectiveness of the main harmonic wave control methods.It can provide references for harmonic control of the ship integrated power system.
