Comparative analysis of power quality on bus-bars of the main switchboard and terminal of exemplary load at marine microgrid

摘要

The paper's aim is to analyze and discuss results of experimental investigation of power quality parameters at two points of exemplary ship power system. Namely, the bus-bars of the main switchboard and terminal of exemplary load (the electric motor of deck crane pump) have been considered. Particularly, measured voltage and frequency deviations are shown, completed by distortion analysis. The level of distortion and their propagation are presented.
