Control for Wind Turbine System using PMSG when Wind Speed Changes

Abstract

This paper presents the proposed model to control grid-connected wind turbine by permanent magnet synchronous generator (PMSG). With the wind speed changing continuously, the rotor system needs to be able to self-regulate according to wind speed and direction to ensure efficient operation of the turbine. The PMSG was chosen because the magnetic flux is always available thanks to the permanent magnet system glued to the rotor surface. The generator provides power with low rotational speed but high efficiency. These are the important advantages of using PMSG for wind turbine. Matlab - Simulink software was used to design the controllers and the survey results proved that this control system meets the power quality requirements when connecting to the grid and optimizing the energy conversion process for turbine wind.
