Modeling and Simulation of Marine Current Energy Conversion System with Six-Phase Permanent Magnet Synchronous Generator

Abstract

This paper presents the analysis and simulation for a marine tidal current turbine system with a sixphase permanent magnet synchronous generator. The aim is to demonstrate the possibility of harnessingelectricity generation for small towns along continental shorelines from strong marine tidal currents in thecoastal region of the Gulf of Guinea along the Southwest region of Nigeria. Due to its advantages of being aclean form of renewable energy and much more predictable than wind and solar, marine current energy hasreceived much attention in recent years. One of the most popular technologies for producing wind and tidalenergy is the permanent magnet synchronous generator (PMSG), which is suitable for low speed tidal currentand offers better power control choices for marine current turbines with a horizontal axis. However, multiphasePMSG is a machine for reaching this goal for low maintenance, high reliability systems in the tough underwatercircumstances. Due to the turbine power coefficient's ability to effectively follow the ideal curve with anychange in water current speed, the maximum electrical power extraction of 198 kW is made possible within thepermitted range of tidal currents. The effectiveness of the proposed model was extensively investigated withMATLAB/Simulink software
