Substantiation of usage expediency and analysis of exploitation problems of low-power wind turbines
(Lviv Polytechnic Publishing House, 2015) Korendiy, Vitaliy; Vergeles, Vitaliy; Lviv Polytechnic National University
Wind energy is considered as one of the most perspective, developed and ecologically clean energy resource. Nevertheless, it is associated with several harmful factors which influence environment. That’s why basic causes and zones of vibration initiation in wind turbines, as well as negative vibratory and acoustic factors of wind turbine influence on natural beings, are analyzed. In conclusion it is substantiated that the ecological problems of low-power wind turbines may be neglected and they should be widely used for economic development and energy independence improvement of our country.
Combined mechanical systems of anti-storm protection of horizontal-axis wind turbines
(Lviv Polytechnic Publishing House, 2015) Korendiy, Vitaliy; Vergeles, Vitaliy; Lviv Polytechnic National University
The necessity of further improving of existent regulation mechanisms is motivated for the purpose of increasing of accuracy of power regulation, effectiveness and reliability of wind turbines functioning in wide range of wind speeds. The prospects of creation of combined mechanical systems are considered, where the possibilities of simultaneous blades turning and folding, blades turning (or folding) and wind-wheel deflection out of wind direction are provided.
