An offshore wind energy conversion system based on a Permanent Magnet Synchronous Generator connected to grid -modeling and control strategies
Résumé
This paper presents modeling and control strategies of 5MW Permanent Magnet Synchronous Generator (PMSG) for offshore wind energy conversion application. The PMSG is connected to electrical grid of 20kV phase to phase RMS voltage using a back-to-back converter. The contribution of this paper is focused on energy management strategies using “grid code”, where the required power profile is fixed by electrical grid manager without any consideration for wind speed variations. For this study, it is assumed that the available power is higher than required power for electrical grid. The proposed control strategies include a Maximum Power Tracking (MPPT) for PMSG speed control, active/reactive power control, and DC-bus voltage management. To show the performances of the control, some simulation results are presented and analyzed using Matlab/Simulink software.
