Abstract

To analyze the slope characteristics of solar power plant installation region in Gangwon province, the installation status of solar power plant in Gangneung and Wonju city were investigated using GIS technique and satellite map. The solar power plant installation of Gangneung and Wonju city is 36 and 48 regions. Through topographical data of solar power plant installation region, a database for area, slope inclination, and elevation was construced. Based on the database, the slope characteristics of solar power plant installation region in Gangneung and Wonju city was analyzed. The results showed that the slope of Wonju city has a relatively higher slope inclination than Gangneung city. In addition, Gangneng and Wonju cities have many regions with maximum inclination of 15° and 34° or more within the solar power plant.

본 연구에서는 강원 지역의 산지 태양광 발전시설이 설치된 지역의 사면 특성을 분석하기 위해, GIS 기법과 위성지도를 활용하여 강릉과 원주 지역의 태양광 발전시설 설치현황을 조사하였다. 강릉과 원주 지역의 태양광 발전시설은 각각 36, 48개소의 발전시설이 설치되어 있는 것으로 나타났다. 또한, 강릉과 원주 지역의 태양광 발전시설 설치지역에 대한 지형자료를 수집하여 면적, 사면경사, 해발고도 등의 데이터베이스를 구축하였다. 이후 구축된 데이터베이스를 활용하여 강릉과 원주 지역의 산지 태양광 발전 시설이 설치된 지역의 사면 특성을 분석하였다. 분석결과, 원주 지역의 사면은 강릉 지역 보다 더 높은 사면경사를 갖는 것으로 나타났다. 또한, 강릉과 원주 지역의 태양광 시설 내에서 15°와 34° 이상의 최대경사를 갖는 지역이 상당수 존재하는 것으로 나타났다.
