초록

점차적으로 지구의 화석연료가 고갈됨에 따라, 효율적인 에너지 저장과 함께 그린에너지에 대한 기술과 수요가 절실히 요구된다. 풍력에너지는 현재 세계에서 가장 빠르게 확장되는 에너지원이다. 하지만 엄청난 가격의 대형풍력발전기 설치비와 정격풍속인 12 m/s 이상을 요구하는 상황에 따라 내륙에서의 풍력발전의 설치는 어려운 상황이다. 따라서 위의 문제를 해결하기 위하여, 저풍속에서도 발전가능한 소형풍력발전기를 실험하고자 하였다. 본 연구에서는 내륙에서의 풍황조건을 분석하고, 300 W와 1 kW 용량의 소형풍력발전기를 옥상에 설치한 후, 그들에 대한 발전효율 특성을 비교하였다.

As the world-wide supply of fossil fuel sources decreases, the need for efficient energy conservation in addition to developing green energy technologies becomes critical. Wind energy is now regarded as one of the most rapidly expanding energy sources in the world. However, due to the high cost for the foundation of large turbines and the high wind speed (over 12 m/s) required, it is very difficult to establish inland wind power plants. In order to solve issues mentioned above, experiments were performed using the small wind power system operated in a low wind speed. In this research, inland wind condition was first analyzed, and 300 W and 1 kW small wind power generators were then installed on a roof and efficiencies of generating electricities were compared.
