1. INTRODUCTION Vertical Axis Wind Turbines (VAWTs) offer a promising alternative to Horizontal Axis Wind Turbines (HAWTs), particularly in urban areas and locations with turbulent wind conditions. Unlike HAWTs, VAWTs capture wind from any direction, making them adaptable to fluctuating wind patterns. The Savonius turbine, known for its simplicity and low manufacturing costs, is ideal for small-scale, low-speed applications. Advancements in aerodynamics, materials, and control systems have improved its efficiency, making it more competitive in the wind energy sector. VAWTs, including the Savonius type, are particularly suited for space-constrained areas and urban environments. Despite challenges like lower efficiency at higher wind speeds and mechanical stresses, ongoing research aims to improve their performance and durability. This paper reviews the design, development, and performance of Savonius-based VAWTs, highlighting their potential for sustainable energy generation.
Chart 1- Methodology Design: The turbine is designed using CAD software, modeling the aerodynamic properties and optimizing geometry for various wind conditions. Component Selection: Components are selected based on material properties, durability, and cost-effectiveness to balance performance and longevity. Fabrication and Assembly: Components are fabricated and assembled with precision to ensure proper alignment and structural integrity.
1.1 METHODOLOGY
Electrical Integration:
The methodology for this study on Savonius Vertical Axis Wind Turbines (VAWTs) is structured in a series of phases, each contributing to the overall design, development, and optimization of the turbine system. The following steps outline the process:
The electrical system is integrated, connecting the generator to the rotor shaft and configuring power electronics for optimal energy output. Performance Testing and Optimization: The turbine undergoes testing to assess efficiency and power output. Adjustments are made based on data to enhance performance.
