The Development of Low Voltage Generation System Using a Compact Vertical Axis Wind Turbine

Abstract

developed system consists of a VAWT with diameter of 1 meter and height of 1 meter, a permanent magnet alternator and a load control unit. The results of simulation and analysis of 3 VAWT with different structure using SolidWorks Flow Simulation software illustrate that 3 blades - Lenz type VAWT has the highest performance then it is constructed and direct coupled to a 5 phase permanent magnet alternator with 350 turn/coil. The experimental results show that the developed system starts to generate the electrical voltage at wind speed of 0.6 m/s and increases the electrical voltage to the level that can use for battery charging when the wind speed is of 5.2 m/s or higher. The experimental results illustrate that the developed system has sufficient efficiency to continuously develop and to apply in the sight in the near future.
