Harmonic Compensation in Ship Power System Using Peak Detection Control Strategy Based Shunt Active Power Filter

The expanding use of nonlinear loads in marine electrical systems leads to new challenges in main-taining and enhancing the power quality and overall sys-tem stability. One of the main problems caused is the de-terioration of the waveform of the current and voltage. The primary aim of this study is to examine and evaluate the application of a shunt active power filter (SAPF) with a peak detection control system in a shipboard power system and the possibility of reducing the THD (total har-monic distortion) at PCC (point of common coupling) of the nonlinear loads. Using a proposed mathematical model and simulation software different case studies are presented with a comparative analysis of the power system performance with and without the presence of SAPF.
