한국 서해안의 해상풍력발전 부존량 평가

국문 초록 (Abstract)

본 연구에서는 국내 서해안의 해상풍력 발전을 위한 적지를 검토하기 위해 기상청에서 제공하는 6개 지점(서수도, 가대암, 십이동파, 갈매여, 해수서, 지귀도)의 2014년 연간 풍속 자료를 수집하고 이를 분석하였다. 관측된 풍속 자료는 Rayleigh 모델과 Weibull 모델에 적합하였으며, 풍속 출현빈도에 따라 연간 부존량을 추정하였다. 풍력발전기 모델로는 GWE-3kH(3 kW급) 터빈과 GWE-10KU (10 kW급) 터빈을 선정하였으며 이의 성능곡선을 이용하였다. 그 결과, 서수도, 가대암, 십이동파, 갈매여, 해수서, 지귀도의 연평균 풍속은 각각 4.60, 4.5, 5.00, 5.13, 5.51, 5.90 m/s로 나타났으며, 연간 발전량은 10,622.752, 11,313.05, 13,509.41, 14,899.55, 17,106.13, 19,660.85kWh로 나타났다. 6개 지점의 연평균에너지 밀도는 전체적으로 poor와 marginal 계급으로 나타났으며, 터빈 이용률은 지귀도가 22.44%로 가장 높게 나타났다.

In this paper, annual wind data in 2014 at six locations(Seosudo, Gadaeam, Sibidongpa, Galmaeyeo, Haesuseo, Jigwido) are collected and analyzed in order to review optimal candidate site for offshore wind farm in the Western Seas of Korea. Observed wind data is fitted to Rayleigh and Weibull distribution and annual energy production is estimated according to wind frequency. GWE-3kH(3 kW-class) and GWE-10KU (10 kW-class) turbine are selected as wind turbine. Also, power curve are used to calculate wind energy potential. As a result, annual mean wind speed at six locations(Seosudo, Gadaeam, Sibidongpa, Galmaeyeo, Haesuseo, Jigwido) were calculated about 4.60, 4.5, 5.00, 5.13, 5.51, 5.90 m/s, respectively. In addition, annual energy production were estimated at 10,622.752, 11,313.05, 13,509.41, 14,899.55, 17,106.13, 19,660.85 kWh. Generally, annual mean energy density were between poor and marginal class and capacity factor at Jigwido was calculated at 22.44%. Its value is higher than the others.
