Double Sensor를 이용한 3kW급 태양광발전시스템에 관한 연구

Abstract

The fossil energy of existing main resources is exhausted globally. The renewable energy get the limelight and studies have been made actively to increase the efficiency. As renewable energy, wind power energy, solar power energy, and etc. are used to energy production in a number of ways. Among these, PV system is one of the unlimited energy source and it don't need transport of fuel, mechanical operation, and the local temperature. Also, advantage of PV system's are maintenance of PV equipment, and easy to equipment and installation. This study focused that PV system was enhanced by improving structural part because research of software part of PV system is already saturated ways to chases sun have such as PV system of fixed array, semi-fixed array, sensor, program, and hybrid. sensor PV system is ideal way among the different methods except the tracking error of part shading of sun light. In this paper, The 3kW double-sensor PV system was proposed. This is organized into two sensor at proposed system at upper side and right side. these are controlled each device of azimuth and elevation. In result, precise tracking control was more efficiency than original sensor system. In addition, proposed way improved the disadvantage of the problem of partial shading of the sensor system. During a month, the proposed 3kW double-sensor tracking PV system and 3kW fixed type PV system gained 569.93507[kWh] and 408.5257[kWh], respectively. In addition, thorough out simulation. it was confirm that proposed system improve the efficiency of 28.85% than fixed system through generation outputs. In simulation, average efficiency gap between semi system of fixed array and sensor array was 17.56[%]. go through data, it was confirm that proposed system improve the efficiency of 11.28[%] more efficient than original sensor system. Thus, we confirmed that PV system of double-sensor type was more efficiency than existing PV system.
