Abstract

The PV power generation system is a comprehensive system that transmits the power generated through a PV panel to a grid connection and is composed of a solar panel, a structure, and an inverter grid connection system. One technology to increase the amount of power generated involves changing the incident angle of sunlight. This study examined the structure and control of a single-axis tracking PV system that increases the amount of power generated by changing the incident angle. The core content is a single-axis control system and technology configured to rotate the solar structure in the east-west direction around the north-south axis. A solar structure that follows the sun from sunrise to sunset in the east-west direction needs to secure structural stability and solar tracking control performance. A single-axis tracking system can generate up to 25% more power.

태양광 발전 시스템은 태양광 패널을 통해 발전된 전력을 계통연계를 통해 전송하는 종합 시스템이다. 발전량을 증대시키는 기술로써 태양광 입사각을 변화시켜 발전량을 증대시키는 추적식 태양광 발전장치 기술이 있다. 본 논문은 입사각을 변화시켜 발전량을 증대시키는 단축 추적식 태양광 발전장치의 구조물과 제어에 관한 연구이다. 핵심 내용은 태양광 구조물이 남북축을 중심으로 동서 방향으로 축회전하도록 구성한 단축 제어장치 및 기술이다. 일출로부터 일몰까지 동서방향으로 태양을 추종하는 태양광 구조물은 구조적 안정성과 태양광 추종 제어 성능 확보가 필요하다. 단축 추적 발전장치는 최대 25% 이상의 발전량 증대를 기대할 수 있다.
