Pitch Angle Control of a Wind Turbine Conversion System at High Wind Speed

This work presents the problem of the wind energy conversion system when wind speed exceeds the nominal one. The goal of this paper is to control the blade pitch angle at high wind speed for the protection of the wind turbine. The proportional-integral controller is used as a conventional method to regulate the pitch angle. The simulation results show that the pitch angle controller can operate to protect the system at high wind speed.
