Improve Efficiency of Horizontal Axis Wind Turbine by Adding Permanent Magnet Arrangement On System

The demand for renewable energy sources is rapidly increasing, with wind energy playing a vital role in sustainable power generation. Horizontal Axis Wind Turbines (HAWTs) are the most widely used configuration; however, they face limitations such as high cut-in wind speed, reduced efficiency at low wind conditions, and mechanical losses during start-up. This project explores methods to enhance the performance of horizontal-axis wind turbines (HAWTs) by integrating permanent‐magnet components. In particular, it investigates how permanent magnets can increase starting torque to lower the turbine’s cut-in wind speed, and how a permanent-magnet synchronous generator (PMSG) can boost electrical conversion efficiency. Combined aerodynamic and magnetic design changes are expected to lower the minimum operational wind speed and raise overall system efficiency. This project proposes the integration of a permanent magnet arrangement into the turbine system to enhance efficiency and overall energy output. The permanent magnets are expected to provide magnetic lift and torque assistance, enabling smoother start-up at lower wind speeds while simultaneously improving generator performance through reduced electrical and mechanical losses.The research involves design and simulation of a modified HAWT system using CAD and analytical tools, followed by prototype development and experimental testing. Comparative analysis will be conducted between the conventional turbine and the magnet-assisted system to evaluate improvements in start-up speed, efficiency, and power generation. The expected outcome is a significant reduction in cut-in wind speed and an overall increase in energy conversion efficiency, making the system more viable in low-wind regions.
