Modelling and control of permanent magnet synchronous generator based on three level NPC using fuzzy PI

Öz

Recently, the permanent magnet synchronous generator (PMSG) has been gained attention by wind turbine (WT) manufactures due to advance of control system and power electronics. The permanent magnet synchronous generator based on three level neutral point control (NPC) system using fuzzy logic control proportional integral (FLC PI) is proposed in this study. The NPC systems of DC link are implemented more easily than two level systems. The NPC systems provide better harmonic reduction than conventional two level voltage source converters. The control strategies of the NPC systems reduce semiconductor losses. The proposed system can be implemented to the multi-level converters above three-level. The proposed system is developed using the steady state technique. The performance of the PMSG system under variation operation condition is investigated in this study and the performances of the PMSG based on three level NPC using FLC PI are analyzed. The validity of the proposed system is implemented and verified in the MATLAB/Simulink using three-level insulated gate bipolar transistor (IGBT) converter.
