엄청난 자원의 매장고, 국가간의 대규모 교역을 가능케 한 항로, 어족자원의 공급원등으로서 인류의 생존과 번영에 일익을 담당하고 있는 바다는 인간의 증가하는 에너지 수요를 지속적으로 감당할 수 있는 무공해에너지의 보고로도 다가오고 있다. 그러나, 에너지 밀도가 타 에너지에 비하여 상대적으로 낮아 큰 규모의 에너지추출장치가 필요하다는 단점에도 불구하고, 대부분의 바다에서 하루에 두 번 씩 발생하는 조석현상을 이용하는 조력발전은 조석의 반복적이고 주기적인 특성 , 태양계가 존속하는 한 영구히 발생한다는 영속성, 현대과학과 관련기술의 진보 등으로 전 세계적으로 그 개발에 인류의 관심이 높아져 있다. 현재 조력발전소가 건설 중인 시화호는 포화상태에 있는 수도권에 공업용지를 공급하고 우량농지 조성으로 경쟁력 있는 농업을 육성하기 위하여 담수호로 조성되었으나,하수처리장 등 기초환경시설이 미비한 상태에서 인근지역으로부터 오염물질이 유입되어 수질이 악화되자 정부는 수질개선을 위하여 시화호를 해수호로 용도를 변경하였다. 본 논문에서는 조수간만의 차를 이용하여 무공해 전력을 생산하는 조력발전의 원리 및 최적발전량 산정기법과 높은 조수간만의 차로 조력개발적지로 유망한 서해안에 건설하게 될 시화호 조력발전소의 사업 및 기후변화협약 이행 시 기대효과 등에 대하여 논하고자 한다.

세계 최대 시설용량이며, 국내최초인 조력발전소의 마무리공정이 한창 진행되고 있는 대역사의 현장을 지난 17일 오후 2시에 찾았다. 짭쪼름한 바닷내음이 점차 진해진다 싶을 때 시야에 들어온 '청정 무공해 전력생산기지' 시화조력발전소. 발전소는 경기도 안산시 오이도와 대부도 사이를 잇는 길이 11.2Km 시화방조제 중간(작은 가리섬)에 위치한 가운데 본격가동의 카운트다운을 준비하고 있다. 지난 4월 10호기를 시작으로 6개월간에 걸친 각종 설비기능시험 등을 거쳐 오는 11월 상업운전을 통해 본격적인 전기 생산에 돌입할 예정인 시화조력발전소의 건설 의미와 주요시설 및 설비구성, 그리고 준공에 따른 기대효과 등을 조망해 본다.

This paper presents an optimal operating scheme by integrating Sihwa tidal power into NamSihwa systems. For optimal operation of NamSihwa systems, the sea levels of 1 minute interval using cubic interpolation based on the forecasted levels of high and low water are calculated. Especially, it is compared by three schemes to purchase total power from transmission system to purchase total power from tidal power system in time period that can generate tidal power and to purchase total power by comparing purchase costs from transmission system and tidal power system. The scheme may contribute to energy save in Korea that natural resources are lacking.

Currently, many nations in the world make a strong effort to exploit the new and renewable energy. Tidal energy is the constant and regular power sources with higher and more stable quality compared to other renewable sources. The present paper reports the status of tidal energy analyzing its latest technology and development. In addition, a feasibility study on two types of tidal power plant(TPP) systems is conducted based on many assumptions, conditions and data involved in the Korea environment. The Sihwa and Uldolmok TPP are considered as the reference of tidal barrage(TB) and tidal in stream energy conversion(TISEC) type, respectively. While TB technology is currently mature and reliable, there still remain many environmental issues. Whereas, TISEC is recently received more attention due to its environmental friendly aspect. Therefore, the TISEC is believed to be very promising technology as the TPP. The unit electricity generation cost of Sihwa TPP is approximately 67.3 KRW/kWh. However, considering additional cost of Sihwa lake construction, it increases to 254 KRW/kWh. In Uldolmok, the unit electricity generation cost is calculated to be about 400 KRW/kWh, which is even higher than that of Sihwa TPP. This is ascribed to high cost of TISEC device and construction cost due to its technological infancy as well as relatively small power capacity. Nevertheless, the TISEC technology would be substantially developed in the future due to its many advantageous features.

The intertidal area in Lake Sihwa formed after operation of Sihwa-Lake tidal power plant and the change of the area in Lake Sihwa by period were analyzed. For computation of the intertidal area, remote sensing techniques were applied and high resolution Digital Elevation Model (DEM) was generated with root mean square (rms) error 14.4 cm. The intertidal area was $165.1km^2$ in 1910s, $115.2km^2$ in 1991 before completion of Sihwa dyke, $5.6km^2$ in 2010 during the period on operation of sluice gate, and $20.3km^2$ in 2013 after operation of Sihwa tidal power plant. Intertidal in Lake Sihwa was nearly dissipated after completion of Sihwa dyke, but significantly increased with operation of Sihwa tidal power plant from April 2012 as developing a regular tide environment and increasing of sea water flux. The re-formation of tidal flat of Sihwa Lake is an uncommon case. This study that precisely analyzed on the area of artificially formed Sihwa tidal flat would be applicable for management and making conservation plan.

The basin of Lake Shihwa is one of highly industrialized region of Korea and a current environmental issue of study area is the operation of tidal power plant (TPP) to improve water quality. The application of water quality index (WQI) which integrates five physiochemical parameters (transparency, DO, DIN, DIP and chlorophyll-a) of water quality in Lake Shihwa and outer sea during 2011~2012 were performed not only to evaluate the spatial and temporal distribution of the water quality but also to assess the effect of water quality improvement by the operation of tidal power plant. The higher WQI values were observed in monitored sites near the industrial complexes in Lake Shihwa and the outfall of wastewater treatment plants (WWTPs) in outer sea. This indicates that the quality of seawater is influenced by diffuse non-point sources from industrial, municipal and agricultural areas in Lake Shihwa and by point sources from the effluence of municipal and industrial wastewater throughout WWTPs in outer sea. Mean WQI value decreased from 53.0 in 2011 to 42.8 in 2012 of Lake Shihwa. Water quality has improved significantly after TPP operation because enhancement of seawater exchange between Lake Shihwa and outer sea leads to improve a hypoxic condition which is primarily a problem in Lake Shihwa. Mean WQI of outer sea showed similar values between 2011 and 2012. However, the results of hierarchical cluster analysis and the deterioration of water quality in summer season indicate that the operation of tidal power plant was not improved the water quality in the upper most area of Lake Shihwa. To successfully improve overall water quality of Lake Shihwa, it is urgently necessary to manage and reduce of non-point pollution sources of the basin of Lake Shihwa.
