Summary

 
Object and purpose of research. This paper discusses an electric propulsion (EPS) system with switched-reluctance motor (SRM) to develop and verify the computer-based model of SRM propulsion drive and investigate voltage harmonics in an SRM-powered marine EPS.
Subject matter and methods.The study was performed on a computer-based model of EPS as per common circuit simulation methods for electric power systems and their elements.
Main results. This work included development and validation of a computer-based circuit model of an SRM propulsion drive. It identified of voltage and current harmonics in drive elements and estimated the effect of assumptions upon the deviations between calculation results and experimental data, with calculation of main switchboard (MSB) voltage nonsinusoidality ratio in an EPS with synchronous generator and SRM propulsion drive of commensurable capacity. The study also outlined the ways for further improvement of harmonics.
Conclusion. Computer-based circuit model of SRM propulsion drive enables sufficiently accurate calculation of transitory and steady processes taking place in switched-reluctance motor. Simulated electromagnetic processes in the system, as well as power exchange between phase windings and DC link of commuting converter correspond to the real ones. This model could be used to investigate the effect of SRM drive operation conditions upon EPS power quality that might be further improved by the optimization of control pulse duration ratios for phase module keys.
