본 논문은 PSCAD/EMTDC프로그램을 이용한 제주-해남 HVDC시스템의 해석모델 개발과 해석모델을 이용한 제주-해남 HVDC시스템의 운전특성에 대한 분석 내용을 기술하였다. 제주-해남 HVDC의 안정적인 운용을 위해서는 HVDC시스템의 이해와 함께 제주교류계통의 계통특성도 같이 고려되어야 한다. 이를 위해서는 제주-해남 HVDC와 제주교류계통을 포함하는 시뮬레이션 모델을 개발하여 다양한 상황에서의 시뮬레이션을 수행하여야 한다. 본 논문에서는 AC계통과 DC 계통의 상호작용에 의한 영향 분석과 교직연계계통의 계통운용 특성에 대해서 EMTDC 제주-해남 HVDC모델과 제주 AC계통 등가축약 모델을 이용하여 분석한 결과를 설명하였다. PSCAD/EMTDC는 EMTP와 더불어 전력시스템의 과도현상 해석을 위한 신뢰성 있는 프로그램이다.

논문은 전류원 HVDC로 연계되어 있는 제주-해남 계통을 전압원 HVDC로 연계하였을 경우에 대한 특성 분석에 대해서 기술하고 있다. 기존의 제주-해남 HVDC시스템은 교류계통 전압의 외란에 의해서 전류실패가 발생할 수 있으므로 연계되는 교류계통 모선에 무효전력보상설비들이 설치되어 있다. 따라서 기존의 전류원 HVDC 시스템은 대용량의 전력을 전송할 수 있다는 장점이 있는 반면 추가로 무효전력 보상설비들이 설치가 되어야 한다는 단점이 있기 때문에 최근에 선진국에서는 전압원 HVDC 시스템에 대한 연구가 활발히 진행되고 있다. 전압원 HVDC 시스템은 계통사고 또는 교류전압강하로 인한 전류실패가 발생하지 않고, 무효전력을 HVDC 시스템의 용량내에서 유효전력과 독립적으로 제어될 수 있기 때문에 추가로 무효전력 보강설비가 필요하지 않다는 장점이 있다. 본 논문에서 늘 제주-해남 계통을 전압원 HVDC로 연계하는 모델을 PSCAD/EMTDC를 이용해서 개발하였다. 개발된 시뮬레이션 모델은 전압원 HVDC를 이용해서 제주-해남 계통을 연계하였을 경우에 대한 동특성을 분석하는데 유용하리라 사료된다.

To select a suitable seed for aquaculture, four strains of Hizikia fusiformis, collected from Haenam, Wando, Yosu, Chungmu and Pusan, were cultured under similar conditions at Wando, southern coast of Korea from December, 1993 to July, 1994. A comparative study on the monthly growth rate of these plants indicated that the maximum growth was attained by Yosu strain in May but the others in June-July. At the harvest time in May, Yosu strain yielded a maximum of 15.8 kg/$m^2$ of culture rope, while that of Pusan a minimum of 1.5 kg/$m^2$.

This study was performed to investigate the effects of environmental parameters on the growth of Pacific oyster, Crassostrea gigas at old suspended culturing grounds of Korsung Bay and newly deveoped bottom, culturing grounds of Haenam region located in southern coast of Korea. The Kosung Bay was semiclosed and water exchange occurred through the small mouth and the current speed was very slow as the value of below 0.5kn. Haenam was opened and littoral zone. Current speed of the surroundings of this Bay about to 5.0knand transparency was low with the mean depth of 1.2m by the resuspension of the sediments. Water temperature and salinity regimes were suitable for oysters at those sites, however the mean value of those parameters and seasonal fluctuations was high at Kosung. The mean concentration of dissolved oxygen in survey area was above $5.0mg/\ell$. In Kosung, however, it was decreasing in June and showed the minimum with the concentration of $4.0mg/\ell$ in August at the bottom layer and recovered in September. Eutrophication parameters such as COD were 1.44 mg/l at this location. This mean value was higher than that of the Haenam Bay's $0.96mg/\ell$. The men value of chlorophyll-$\alpha$ at Haenam was two times higher than the other sites. Growth of shell height and meat weight of oysters at Kosung Bay were higher and the fatness was lower compared to thost of Haenam. As a result, absolute growth of oysters was high at Kosung and allometric growth, such as fatness, was good at Haenam. Low water temperature and frequent exposure of oysters to the air during ebb tide may retard the shell growth. On the other hand, relatively high food availability was profitable for the fatness at haenam site.

Cretaceous volcanics and volcaniclastic sediments are abundantly distributed in the Haenam area located at the tip of the southwestern part of the Yongdong-Kwangju depression zone. The Cretaceous strata correlated with the Yuchon Group of the Kyongsang Supergroup are divided into three formations: Hwawon Formation, Uhangri Formation and Haenam Formation in ascending order. The stratovolcanic Hwawon Formation is mainly composed of andesite and andesitic pyroclastics. The Uhangri Formation is the lacustrine sedimentary deposit. The Haenam Formation is composed of Hwangsan tuff, Haenam tuff, Yongdang tuff, Seoho tuff, and also Acidic lava, both being formed by a cogenetic acidic volcanism. The topographic circular structure of the Cretaceous strata was controlled by the doming of Jurassic Sani granite. Cretaceous volcanism in the study area is characterized by the two stages of intermediate volcanic activity in Cenomanian to Albian, and acidic volcanic activity in Campanian to Coniacian.
