시화조력발전소 가동에 따른 기본해양인자 변화 수치모델링

Abstract

The west coast of Korean peninsula is famous for its high tidal range and a series of tidal feasibility studies for the tidal power generation have ever been carried out since late 1970s. Now Siwha tidal power plant (TPP) with installed capacity 254MW is being constructed since 2004 in the Siwha region in the Kyunggi Bay of the Yellow Sea, expected to be completed in 5 years. Tidal regime change has been examined with the condition that Siwha TPP is being operated, based upon numerical modeling approach. It is shown that TPP operation has an broad effect on the tidal regime change in the whole Yellow Sea, even though the magnitude of the M2 tidal amplitude change is relatively small. Other hydrodynamic characteristics such as various sea levels in the Siwha TPP basin and in the outer sea are also examined, as well as the investigation of the discharges from the turbine and sluice gate.
