Output Voltage Characteristics of Wind Energy System Considering Wind Speed and Number of Blades

Abstract

Wind energy offers clean and sustainable form of kinetic energy of air to transform into electrical energy. The efficiency of the wind energy system is dependent on various factors, such as; blade number, wind speed, turbine design and several others (BEWA briefing sheet). Wind turbines with their design are more concerned to bring down the capital cost for renewable energy generation. Therefore, two most important design factors that are wind speed and selection of number of blades have been taken into consideration for this research. In this paper, the relationship for the output terminal voltage with the wind speed and the number of blades has been observed. The lab test setup of wind energy system of heliocentris wind generator was set. The controlled environment with variable fan speed test setup was arranged. It was observed that the output voltage is directly proportional to the wind speed and the number of blades. In future this analysis will be utilized to predict the output power from the wind turbine system and proposed for onsite windmill in the vicinity.
