Performance of Wind Turbine under Different Operating Modes
Résumé
Out of all renewable energy resources wind energy is found to be the most viable energy source due to its availability, pollution free and fast developments globally. Wind turbine, one of the major components of wind energy conversion system is used to capture the energy associated with the wind for driving the induction generator generally adopted to generate electrical power. Power output of wind turbines varies in accordance with the wind variations and as observed from literature, wind turbines may be operated either in constant speed or variable speed operation. However, complicated controls as adopted for such operations make the system expansive and complicated. Keeping it in view, in this paper a new approach based upon the generator control is proposed to analyze the operation of wind turbine under two operating modes. Simulation results as obtained using developed Matlab model prove the effectiveness of such control strategies. Investigations as reported along with the wind speed data for installation site may be helpful to decide the mode of operation for wind turbine to be installed.Keywords: Matlab/Simulink, Renewable energy resources, Wind disturbances, Wind turbine, Wind turbine control
