| 摘 要： | 针对潮流能资源较丰富的成山头外海域,利用FVCOM数值模式,在良好模拟该海域潮流场的基础上,运用能量耗散原理,对该海域的潮流能资源可开发量进行了评估。结果表明,在转换装置的拖拽系数为0.07时,面积为27km2的成山头近岸海域的可开发潮流能资源约为17.9MW,其中大潮期间的可开发量高达37.7MW,而小潮期间则为7.3MW。在此条件下,该海域大潮期间涨急和落急时刻的流速分别减小了40%和38%,但发电装置对潮汐的影响较小,在成山头顶端的高潮潮位仅下降了4cm。

| Abstract: | In this study, the extractable energy resource of the tidal current is estimated using the FVCOM model in the open sea area of the Chengshantou Cape in the area of 27km2, which is known as an area of good potential in the exploitability of tidal current energy. Based on the energy dissipation principle, simulation of the tidal current in this area was performed to estimate the available energy quantity. Our results show that when the drag coefficient of turbines is 0.07, the available energy of the tidal current for the area is 17.9MW, and during the periods of spring tide and neap tide, the estimated energy quantity is 37.7MW and 7.3MW, respectively. The maximum decrease in the current velocity in the flood period and ebb period is 40% and 38%, respectively. However, the tidal level is slightly affected by turbines, which decreases by 4cm only in the spring tide period at the tip of the Chengshantou Cape. |
