杭州湾潮流能资源储量估算

Tidal stream energy assessment of Hangzhou Bay

采用二维数值模拟方法对杭州湾海域的潮流进行了模拟,得到了杭州湾海域潮流流速的分布特征。在此基础上对杭州湾海域的潮流能储量进行估算,得到杭州湾海域潮流能储量约3.59 GW。从数值模拟的结果可以看出,杭州湾口的金塘水道、龟山航门等通道内水深、流急,潮流能密度较大,是潮流能开发的理想海域,通过对这几个通道进行计算,预计可开发量约700 MW。

In this paper,the tide and tidal current of Hangzhou Bay were simulated by a 2-D numerical model.Then the tidal stream energy reserves of Hangzhou Bay were assessed on the basis of the numerical simulation.The results show that the tidal stream energy reserves of Hangzhou Bay are about 3.57 GW,and the hydropower exploitation amount in the several channels of the mouth of Hangzhou Bay is about 700 MW.
