摘要
海洋水电为海洋水动能发电,其中潮汐能电站50多年来经济效益指标一直居高不下,因此提高潮汐能投资效益指标已成为提高其电力市场竞争的关键点;借江河水电工程经验,剖析潮汐电站效益因子,提出其物理模拟实验及数值仿真模拟的主要任务目标,提出其增效因子潮差增量、波浪爬高、纳潮量等与其枢纽布置及效益之间的关联性。剖析潮汐电站可增效与可降耗因子的影响因素,提出其节能降耗研究技术路线;用潮汐能工程实例说明节能降耗研究的关键节点;结合潮汐工程前沿阔长特点,提出利用其开展海洋水力发电多能互补研究的建议。
Ocean water power means power generation from marine water kinetic energy,of which the economic benefit indexes of tidal power stations have been high for more than 50 years.Therefore,increasing the investment benefit indexes of tidal energy has become the key point for improving their competitiveness in the power market.Based on experience in hydropower stations on rivers,the paper analyzes the benefit factors of tidal power stations,puts forward the main tasks and aims of physical simulation experiment and numerical simulation,and the correlation between synergistic factors,tidal range increment,wave run-up and accommodated tide volume,and project layout and benefits.It also analyzes the effect factors of efficiency increase and consumption reduction factors of tidal power stations,proposes the technical path for energy-saving and consumption-reducing study,presents the critical nodes for the above study by taking tidal energy projects for example,and according to the features of long and wide front edges of tidal projects,gives recommendations on carrying out research on multi-energy mutual compensation by ocean water power.
