ANALYSIS AND ASSESSMENT OF TIDAL CURRENT ENERGY RESOURCES IN SEA AROUND PINGTAN ISLAND
Based on the TELEMAC-2D hydrodynamic model,a tidal current field model around Pingtan Island in Fujian province was established.The accuracy of the model was verified by using measured tidal level and tidal current data.As the results,the model can accurately depict the tidal and current characteristics of the study area.On this basis,the spatial-temporal distribution characteristics of tidal current energy resources and the asymmetry of tidal rise and fall in the region were analyzed.The Flux method was combined with Garrett method to assess and compare the exploitable amount of tidal current energy resources in specific regions.Results show that the tidal current energy resources in the waters around Pingtan Island are mainly distributed in three channels:Pingtan Island-Dalian Island,Dalian Island-Xiaolian Island,and Xiaolian Island-Changyu Island,with a peak power density of about 10 kW/m2.The effective flow time is more than 6000 h.The total area of Class I tidal energy resource zone in three channels is 1.05 km2,while Class Ⅱ is 5.11 km2.The exploitable tidal current energy resources calculated by the Flux and Garrett methods are 7.44 MW and 11.74 MW,respectively.
