Abstract


With the rising global demand for electricity, conventional non-renewable energy sources are proving inadequate and contribute significantly to environmental pollution. As a result, renewable energy sources have gained prominence, with wind energy being one of the most viable alternatives. Wind turbines harness the kinetic energy of wind and convert it into electrical power. There are two primary types of wind turbines: horizontal axis wind turbines (HAWT) and vertical axis wind turbines (VAWT). While HAWTs require larger spaces and have lower efficiency, VAWTs are more compact and space-efficient. However, both types still suffer from efficiency limitations. This study focuses on enhancing the performance of a vertical axis wind turbine by introducing modifications to its generator. Unlike conventional designs where the stator remains stationary while the rotor rotates, this research explores a novel approach in which the stator is also set in motion. This counter-rotating mechanism aims to improve energy conversion efficiency and optimize electricity generation.
