Abstract
This dissertation is the documentation of the design and development of a sustainable wind energy conversion system to be employed as a stand-alone electrical energy generator for isolated communities and dwellings. As our global population increases at an exponential rate and our consumerism grows with it, a sustainable source of energy needs to be developed to meet our power requirements. Because of the fast depletion of fossil fuels, there is a current global need for clean and renewable energy sources. Among all the renewable resources wind power is one of the most efficient and environmentally friendly. At present, India is fifth in wind power generation across the world. It is speculated that at most of the places in India wind turbines are not viable due to low wind speed. Hence a wind turbine, which produces energy even at very low wind speed is required. This paper is concerned with the design, implementation and monitoring of such wind turbines for domestic applications. The proposed system is composed of 3 blades using NACA-63215 profile, which is made up of fiber glass materials. A permanent magnet synchronous generator is used for power generation of 250 W. The generated power is rectified and used to charge a lead acid battery of 24 V, 40 Ah. The battery power is then inverted by a pulse width modulation inverter before utilized by the load. The charge controller prevents the battery from overcharging and/or deep discharging. This type of small/micro-wind turbine operates even at low wind speed.
