A Hybrid Active Filter for Damping Harmonic Resonance in Large Shipboard Power System

Abstract

Abstract: A novel hybrid filtering system was designed. This system is composed of both the largecapacity passive filter and the smallcapacity active filter. Considering the fact that the ship’s multicondition operation may cause the change of topology structure and parameters in power system, hybrid filters were introduced. The largercapacity passive filter is to remove the specific order harmonics, and the smallcapacity active filter is to be used in compensation and system finetuning. After being verified in the power system of a large ship, the new filter is proven to have high performancetoprice ratio and is suitable to the multicondition operation of large ships.

Key words: hybrid active filter, adaptive filter, parameter design, harmonic suppression, ships harmonic
