Vertical Axis Wind Turbine Performance Enhancement Via Utilizing the Repulsive Characteristics of Permanent Magnets

Abstract

Humans have been using wind power for past thousands of years to propel sailboats and ships. But from calendar year 1980s, in the energy sector we can see dramatic development in the form of wind energy. Today in renewable power, other than the hydropower, together with solar power, the wind is also most important source energy. Here the wind energy conversion system; consist of turbine which transforms the kinetic energy available in the wind into the mechanical energy, then the mechanical energy is boosted up with the help of gearbox and then generators are used to transform the rotational mechanical energy into the electrical energy. Now this paper mainly concentrates on the implementation of “magnetic propelling phenomenon” to improve the efficiency of the VAWT system and technology will be implemented between the rotating plane and fixed plane below the turbine, in such way that like polarities facing each other to create magnetic repulsion. The natural property of magnetic repulsion which is created between like poles of magnets can be used as a source of energy. Thus this system will operate with an additional feature like, magnetic repulsion characteristics. The force which is created as the result of the magnetic repulsion will also adds kinetic energy to the turbine while converting the wind kinetic energy into the rotational mechanical energy by the turbines, Hence here our PMP-VAWT system has the ability to operate in the both high & low wind speed environment condition with better efficiency due to the implementation of magnetic repulsive characteristics, and here our choice is to demonstrate the efficiency of PMP-VAWT system as compared to the Traditional VAWT system.
