MPPT and pitch angle control of a permanent magnet synchronous generator based wind emulator

Abstract

This work aims at studying the interconnection characteristics of a wind turbine based on a permanent magnet synchronous generator (PMSG) from a wind turbine emulator. The goal is to make a maximum power point tracking (MPPT) analysis and pitch angle control. In first place, wind turbine modeling is done using a DC machine. Then, a maximum power technique MPPT and a wedging angle control strategy will be developed in order to adapt turbine speed to wind speed to maximize and limit power output of the wind turbine (WT). Results of simulation are given to show the performance and the effectiveness of the proposed controls, regarding reference tracking, sensibility to high wind speed variations and unavailability of turbine parameters. The complete system model will be developed in the Matlab/Simulink environment.
