Preliminary Numerical Estimates on Tidal Stream Energy Resources of the Coastal Areas of Shandong Peninsula

摘要

Tidal stream energy is a kind of important ocean renewable energy. Toinvestigate tidal stream energy resource has to be paid much attentionbefore installing tidal stream power generating instruments. So thecandidate article will study and investigate tidal stream energy aroundShandong peninsula. The methods and other processes are following.Numerical simulation method is adopted to get the tidal current ofShandong peninsula surrounding waters for one year. The main 11 tidecomponents’ (Q1, O1, P1, K1, N2, M2, S2, K2, M4, MS4, M6, etc.)harmonic constants and elliptic elements are calculated through usingtidal harmonic analysis method. The characteristics of tidal currentsaround Shandong peninsula are analyzed and the following tidalstreams power density is calculated.The tidal current model is validated by harmonic constants of tidecomponents from over 10 tide stations locating in surrounding areas ofthe peninsula, which shows the reliability of the tidal current model.Tidal streams energy of Shandong peninsula surrounding water areas isestimated based on numerical results. The energy flux available ofvertical transactions of Chengshantou and Changshan Island are studiedin terms of Flux method.In terms of numerical results, the tidal current velocities given by themodel agree with the measured velocities generally. The maximumtidal stream energy density occurs around the eastern end Shandongpeninsula.The details of the analyzing results about tidal stream energy densitydistribution of Shandong peninsula surrounding areas will be giventhrough further analysis. The results will be meaningful to developersof tidal streams energy around Shandong peninsula areas.
