Experimented Examination of Power Produced for Dual Rotor Wind Turbine over Single Rotor Wind Turbine

Abstract

As that wind energy is the vital energy resource which can be used widely to facilitate humane being prolong till the time nature or so called wind is there main aim of this paper is increase extraction percentage of energy from wind using dual rotor wind turbine connected on same axis, analysis were carried out experimentally for the increased power coefficient CP. It has been compared and found that with respect to single rotor or turbine dual wind power is having larger value of CP and torque, moreover instead of using one turbine for two turbine on same axis the value of CP increases with the better balancing stability, further the comparison is made with the performance of single bare wind turbine . Compare to that of single rotor if we used two rotor on same shaft then the torque and power increases on the other hand we will also get large stability due to weight balance condition and was found that large amount of energy can be extracted with comparatively larger value of torque. Experiment have been carried out on single rotor wind turbine and then dual rotor wind turbine after turbine development in the real atmospheric condition due to which different torque ,power produced, rotor speed was achieved which was analyzed and found fruitful where a large amount of power or torque is required
