This research builds wind turbine which working over variable velocity of wind. The proposed construct incorporates three-bladed aerofoil rotor, gear box with ratio 1:8, three-phase doubly-fed induction generator, automatic voltage regulator and tower. Results verify efficacy of this installed structure at wind speed of 7.0- 8.2 m/s. The proposed design generates power output at 3 kW, voltage per phase between 220 V, and frequency of 50 Hz; and exhibits noise just around 60-70 dB which is below the permissible noise threshold of 85 dB.

INTRODUCTION The significant increase of responsiveness to the growth of ecologically clean power sources, namely wind, solar, biomass, and hydroelectric, as a replacement for fossil fuel energy has come from an escalating attention regarding global climate change, environmental contamination, and security of energy supply [1]. Destructive emissions, such as  2 ,  2 , and further toxic litter as in out-of-date coal-fuel power plants could be eliminated through using wind power plants [2]. As the mainly to ensure renewable energy sources, wind power is decidedly projected to lay hold of a greater number in electric power generation in the years to come. Small scale wind power turbines propose a fascinating clean energy resource for isolated areas or island communities. At low wind speeds, power can be harvested by wind turbines and had better be visually well-suited by the milieu and ought to perform including small noise. Enclosed by defining installed sites of wind power turbines applied around populated areas, atmospheric instability perhaps reduced to give consideration toward surrounding structures. Installation difficulties must be carried away to take electric power from wind farms to populated locations, where it is taken to come across demand [3]. Notwithstanding the aforesaid challenges, on the spot continues growing interest as to rooftop wind turbines [4], [5]. Many studies came to be conveyed upon modest scale wind turbines. For instance, Chaudhary et al. [6] studied the design of a small-sized horizontal-axis wind turbine. The aerofoil SG6043 was exposed; through
