Performance Study of a Grid Connected Permanent Magnet Synchronous Generator based Wind Turbine System

The performance of a grid connected permanent magnet synchronous generator (PMSG) based wind turbine mT) system under varying wind velocity is studied in this paper. To achieve variable speed and constant frequency operation, two vector control schemes are adopted for controlling both the converters. Field oriented based vector control scheme is used to control Machine Side Converter (MSC) and grid oriented based vector control scheme is used to control Grid Side Converter (GS C). Maximum Power Point Tracker (MPPT) is also playing a very important role to extract maximum power from wind and hence, perturb and observe (P & O) algorithm is used. Simulation of the complete system is done in MATLAB/Simulink platform and time domain results are taken under varying wind velocity and analyzed those results in details.
