  • 삼천포 보령 당진 등 국내 대형 기력발전단지에서 냉각수로 사용되고 방류되는 해수는 약 150cms로 (100Mwe당 약 5cms) 약 3,000kW 이상의 수력에너지를 보유하고 있으나, 현재 활용되지 못하고 그대로 해양으로 방류되고 있어 이 소수력에너지의 개발 방안을 검토하였다. 발전소 온배수의 원활한 배수를 위한 설계 낙차와 함께 남서해안의 조위변화에 따른 낙차를 이용하는 것으로 소수력 발전 방식과 조력 발전 방식의 특징을 동시에 활용하는 것이다. 국내의 기력발전소 가운데 삼천포, 보령, 하동화력발전소에 대하여 소수력에너지 개발방안을 검토하였으며, 배수로에 댐을 축조하여 방류수 전량을 발전에 이용하는 댐식, 배수로 중간에서 방류수 일부를 취수하는 수로식, 배수로의 빠른 유속을 이용하는 조류식 발전 방안을 중심으로 각 발전소의 구체적 적용여건에 따라 다양한 대안을 검토하여 기술적 가능성 및 경제성이 충분함을 입증하였다.

  • The integrated power system combining a tidal power plant and two ocean current power parks is suggested. It is characterized by the set up of an ocean current power park in the lake side by installing a number of ocean current turbines generating electricity by using sea water flow discharged into the lake side from the turbine generator of a tidal power plant and an ocean current power park in the sea side by installing a number of ocean current turbines generating electricity by using sea water flow exiting into the sea side through the sluice gate from the lake side. The vision of the integrated power system is demonstrated by the simple theory and simulation results of the SIWHA Tidal Power Plant. And it is shown that the newly proposed integrated power system combining tidal power and ocean current power can produce very high economical benefits.

  • Tidal power plants such as Shihwa, Garorim and so on are under construction or planned to construct in Korea. However it can be estimated that the inappropriate community assistant program for tidal power plant is applied because tidal energy is imposed on a new and renewable energy criterion in Korea. Therefore in this paper, the optimum funding and region boundaries of community assistant program for tidal power plants are derived in order to improve beneficial effects of the community assistant program for tidal power plants in Korea.

  • The present paper relates to an integration power system combining tidal power generation and ocean current power generation, and more particularly, to an integration power system combining a tidal power plant and two ocean current power parks, which is capable of increasing the operating rate of power facilities and efficiently generating electrical energy by using incoming seawater into the lake through turbine generators of a tidal power plant or fast flow of seawater discharged to a sea side through sluice gates of a tidal power dam. It is shown that the integration power system is a new promising ocean power system and the ocean current turbine generators in the ocean current power parks of the integration power system are smaller in size and larger in power generation capacity compared with the tidal current turbine generators in the ocean.
