Abstract

In North Korea, hydropower which occupies about 63% of power generation is a major electric power source, and North Korea has many advantages in the geographical for developing hydroelectric power. In this study, Information on the basin and dam capacity for 33 potential development site of hydroelectric dam was analyzed using DEM, and potential annual power generation was estimated by applying results of long-term runoff simulation with MWSWAT model for recent 30-year. The potential annual power generation at 33 dam was estimated to be about 28% of the current hydroelectric power in North Korea. In addition, a priority of dam development in each province was assessed by estimating the scale of an industry and prospecting the population change in the future. And a priority for dam development within the province was estimated based on the dam capacity and the potential annual power generation. The priority of each province was ranked in order of Pyeongannamdo, Hamgyungnamdo, Hamgyungbukdo, Hwanghaebukdo, Pyeonganbukdo, Jagangdo, Ryanggangdo, Hwanghaenamdo, and Gangwondo. The results of this study can be used as an initial review data for advancing to hydropower development project in North Korea.

북한은 수력발전이 전체 발전량의 약 63%를 차지할 만큼 비중이 높고, 지리적으로 수력발전 개발에 많은 이점을 가지고 있다. 본 연구에서는 33개의 북한 댐개발 가능지점에 대해 DEM자료를 이용하여 유역분석 및 저수량을 산정하고, MWSWAT 모델을 이용한 30년간의 장기유출 분석 결과를 적용하여 연간가능발생전력량을 추정하였다. 33개 지점의 연간가능발생전력량은 현재 북한 수력발전량의 약 28% 수준으로 평가되었다. 또한 도별 공업지구 규모를 추정하고, 장래 인구 변동을 전망하여 도별 댐개발 우선순위를 선정하고, 저수량과 연간가능발생전력량을 기초로 도내 댐개발 우선선위를 선정하였다. 도별 우선순위는 평안남도, 함경남도, 함경북도, 황해북도, 평안북도, 자강도, 량강도, 황해남도, 강원도 순으로 나타났다. 본 연구의 결과는 북한지역의 수력발전댐 개발사업의 진출을 위한 초기 검토 자료로 활용이 가능할 것으로 판단된다.
