파력발전기 최적설계를 위한 파랑조건과 설계파랑 산출에 대한 연구

Abstract

This paper is investigated to variation of wave power generation operation rate and operating capacity with the wave condition represented by wave height-period window in order to determine the range of wave height and period for the optimal design of wave power generation unit at Chagui-Do sea area in Jeju For this, It was confirmed that the monthly variation of significant wave height(Hs), zero-up crossing period(Tz) and wave appearance rate distribution are similar through comparison of the field wave data obtained from 2004 to 2005 at Chagui-Do sea area and long-term wave data from 1979 to 2002, which is provided by Korea Ocean Research & Development Institute(KORDI). Take advantage of this result, the Hs-Tz and wave-energy density scatter diagrams are charted using the long-term wave data(KORDI). And n-year return period wave heights are calculated for the estimation of design wave height.
