Current and Sediment Numerical Model Applied in the Project of Campha Thermal Power Plant

The Thermal Power Plant is located in Cam Pha town, Quang Ninh province which is in Vietnam northern alongshore, the plant capacity is up to 2 x 300MW. The recirculated cooling water is designed to intake the seawater direct current waterworks, in which the nearby seawater is used as the source of cooling water. Topographic condition, Geology, wind, wave, Sediment distribution are analyzed. The two-dimensional current and sediment numerical model are adopted. According to different intaking and draining design proposals, sediment movement and seabed evolution process in sea area should be simulated under the action of wave and tide current. The results show that the power station that lay in HongJi-GaiBaoDao sea area belong to the balance region between erosion and deposition, the weak erosion evolution occur after constructing the power station. Under the association action of field measurement tide stencils and characteristic wave, the recommended scheme can satisfy with the intaking water requirement. In view of the action of sinking water, the both side of open channel entrance appear small scale erosion channel, which is good for intaking water. The both side levee toe of open channel and the foreland of intaking water channel exist some scale erosion region, the protective facility need to adopt such as jackstone protective facility.
