摘　　要：船舶电网存在谐波会导致船舶电能质量下降,危害配电系统健康。并联型有源电力滤波装置能够对船舶电网谐波进行抑制,有效地改善船舶电网质量。对并联型有源电力滤波装置主电路直流侧的电容电压进行控制,能够提高装置的稳定性与精确性。本文以我院设计的某型电力推进船为母型,构建电力推进系统仿真模型,通过分析并联型有源电力滤波装置的工作原理,构建谐波抑制仿真模型,并应用PI控制器实现直流侧电容电压的稳定控制。仿真结果表明,PI控制器能够控制直流侧电容电压的稳定,谐波抑制仿真模型具有良好的谐波抑制效果。The existence of harmonics in ship power network degrades the quality of ship power and endangers the health situation of electricity distribution system.Shunt active power filter helps suppress the harmonics of ship power grid and improve the quality of ship power grid effectively.In this paper,a simulation model of electric propulsion system is constructed based on a type of electric propulsion ship designed by our institute.The simulation model of harmonic suppression is constructed based on the working principle of shunt active power filter device.,and a PI controller is used to realize the stable control of DC capacitor voltage.The simulation results show that PI controller helps control the stability of DC capacitor voltage,and the simulation model has good harmonic suppression effect.
