This paper is investigated to variation of wave power generation operation rate, operating capacity and output with the wave conditions represented by wave height-period window. By the use of the long-term wave data from 1979 to 2002 which is provided by Korea Ocean Research & Development Institute(KORDI), we calculated the monthly variation of significant wave height(Hs), zero-up crossing period(Tz) and distribution of wave appearance rate. And using the same wave data, it was charted the Hs-Tz and wave-energy scatter diagrams.

Wave power distribution is investigated to determine the optimal sites for wave power generation at Jeju sea which has the highest wave energy density in the Korean coastal waters. The spatial and seasonal variation of wave power per unit length is calculated in the Jeju sea area based on the monthly mean wave data from 1979 to 2002 which is produced by the SWAN wave model simulation in prior research. The selected favorable locations for wave power generation are compared in terms of magnitude of wave energy density and distribution characteristics of wave parameters. The results suggest that Chagui-Do is the most optimal site for wave power generation in the Jeju sea. The seasonal distribution of wave energy density reveals that the highest wave energy density occurs in the northwest sea in the winter and it is dominated by wind waves, while the second highest one happens at south sea in the summer and it is dominated by a swell sea. The annual average of wave energy density shows that it gradually increases from east to west of the Jeju sea. At Chagui-Do, the energy density of the sea swell sea is relatively uniform while the energy density of the wind waves is variable and strong in the winter.

진동수주형 파력발전시스템은 안정된 작동환경 때문에 널리 사용되는 시스템 중의 하나이다. 진동수주형 파력발전시스템은 크게 3단계의 에너지변환을 거치게 되는데, 각 단계 마다 필요한 에너지변환장치의 설계가 필요하다. 본 논문은 1차 에너지변환장치인 OWC 챔버와 2차 에너지변환장치인 임펄스터빈의 표준설계를 수행할 수 있는 S/W를 개발하여 소개하고자 한다. Because of the steady operating condition the OWC type wave energy converter is the most widely used device. The device need three state of energy converting process to generate the electrical power form the wave energy. Therefore, the design of each converting system is the most important and difficult work. This paper deals with the development of standard design S/W for OWC chamber and Impulse turbine, which act as 1st and 2nd energy converting function.
