One sensor방식에 의한 추적형 태양광발전시스템에 관한 연구

Abstract

The latest fast industry development and continuous increase of demand for power by elevation of standard of living and fossil energy of run dry, interest about worldwide new recycled energy is elated by environmental pollution problem etc. Chooses photovoltaics, wind energy, fuel cell by 3 periods emphasis business in our country and is helping in development and supply. Because photovoltatic power generation out of this is no air pollution or occurrence of noise, and source of energy is infinite, lively study is proceeded as alternate energy source. The sun tracking device chases position of the sun that change according to time and solar cell module always heads the sun. In this paper, the sun and solar cell module suggested Two-axis tracking system of one sensor method that can control azimuth and elevation by 1 sensors in double sensor mode that used 2 sensors to Two-axis tracking system that control azimuth and elevation of the sun in existing so that form normal and manufactures proposed tracking system and executed actuality driving of system. It is Two-axis tracking system that control azimuth and elevation to control to be reduced for solar cell module as proposed tracking system uses 1 sensors and the sun always forms normal. Two-axis tracking system of one sensor method that propose in paper that could reduce electric power consumption and sees than fixed type preventing action and the most efficient driving and needless drive could confirm that generation efficiency of about 23 [%] increases. To heighten efficiency of solar cell doing to receive more sunlights chasing the sun, done tracking device have proceeded a lot of studies in large size way. Therefore, is expected that will do big part in the sun tracking supply through utility study about persistent generation efficiency constructing monitoring system of the sun tracking of this paper.
