Response Surface Optimization of Power Voltage in Pilot Scale Wind Turbine Model

Abstract

Wind turbines are of great significance due to their utilization of renewable energy sources, thereby reducing dependency on fossil fuels. The primary objective of this research paper is to optimize the output voltage by varying the pitch angle and the number of blades, utilizing a central composite response surface design. Through the analysis conducted, it was observed that the output voltage exhibits an increasing trend as the number of blades is increased within the range of 2 to 6. Furthermore, the output voltage demonstrates an initial increase with an increase in blade pitch angle from 0 to 45 degrees, followed by a subsequent decrease. The highest attainable output voltage, reaching 2630 mV, was achieved when the pitch angle and number of blades were at 29 and 6, respectively. The findings of this study has potential for scaling up the operations to industrial wind turbine power plants.
