Assessment of Flicker Due to Vertical Wind Shear in a Wind Turbine Mounted on a Hill with Linear Approach

Abstract

Wind energy is now one of the prime renewable energy sources. Power quality of wind energy is one of the prime issues. In this paper model of flicker produced in a wind turbine mounted on a hill is deliberated. Vertical wind shear is one the important factors affecting flicker producing in wind turbine. In this paper mathematical model of flicker initiated in wind turbine mounted on a hill is developed with linear approach. The parameters considered for the development of the model are vertical wind shear, blade length, turbine height. Hill height and hill slope is also considered. The tower considered is tubular tower. The model is developed for a three bladed horizontal axis upwind wind turbine. The validation of the model is also done with experimentation.
