초록

본 연구에서는 우리나라 840개 표준유역을 대상으로 연평균강우량을 수집하고 티센망을 구축하였으며 티센망을 통해 면적강우량을 산정하고 표준유역별 연평균유량을 산정하였다. 산정된 연평균유량에 단위낙차, 발전소 효율, 가동률 등을 고려하여 연간 소수력발전가능량을 산정하였다. 산정결과, 한강권역에서의 표준유역 최대 소수력발전가능량은 17,917.2MWh, 평균 572.2MWh로 산정되었으며 낙동강권역에서 최대 13,051.0MWh, 평균 1,318.2MWh, 금강권역에서 최대 6,587.3MWh, 평균 1,074.9MWh, 섬진강권역에서 최대 4,146.0MWh, 평균 760.3kW, 영산강권역에서 최대 2,699.6MWh, 평균 487.1MWh 순서로 산정되었다. 또한, 소수력발전가능량이 1,000MWh 이하인 표준유역이 708개로 전체 중 84.3%인 것으로 분석되었으며 1,000MWh 초과 5,000MWh 이하인 표준유역은 84개로 전체의 10%, 5,000MWh 초과 10,000MWh 이하인 표준유역은 32개로 전체의 3.8%, 10,000MWh 초과인 표준유역이 16개로 전체의 1.9%인 것으로 분석되었다.

In this study, annual average precipitation was constructed and Thiessen network was developed according to 840 standard basin in Korea. Annual average discharge was estimated by applying areal rainfall through Thiessen network. Annual small hydro-electric power was calculated considering annual average discharge, unit head drop, power plant efficiency and operating ratio. The results showed that the maximum small hydro-electric power of standard basin was 17,917.2 MWh and has an average of 1,572.2 MWh from all the standard basins found on the boundary area of the Hangang basin, and for the Nakdonggang, 13,051 MWh was found to be the maximum power of standard basin and has an average of 1,318.2 MWh from all the standard basins. Also, the Geumgang’s, Seomjingang’s and Yeongsangang’s maximum small hydro-electric power of standard basin resulted to a value of 6,587.3, 4,146, and 2,699.6 MWh respectively with an average small hydro-electric power from all the standard basin of 1,074, 760.3 and 487.1 MWh respectively. Furthermore, it was found out that under the 0–1,000 MWh range, 708 standard basins or represents 84.3% of the over-all percentage fall under this category, while for the 1,000–5,000 MWh mark, a total of 84 or 10% were included and for the 5,000–10,000 MWh and over the 10,000 MWh limit, a result of 32 standard basins or 3.8% and 16 standard basins or 1.9% of the over-all percentage were recorded respectively.
