Shipboard power quality management using the controllably inductive power filtering method

This paper presents a controllably inductive power filtering (CIPF) method applied in the shipboard power system (SPS). The CIPF method can realize the bi-directional and active-tracking elimination of harmonics from the nonlinear load and the generators at the source-side. The three-phase circuit and mathematical models of the CIPF system are established. By means of the theoretical analysis on the harmonic distribution characteristics, the operating mechanism of the CIPF method is revealed. To further improve the filtering performance, an advanced control strategy to replace the conventional resistive control is designed. Finally, based on the prototype system in the laboratory, the proposed CIPF system applied in the SPS is validated.
