【摘要】：虽然中国拥有丰富的潮汐资源,但是潮汐发电产业在很大程度上落后于水力、光伏、风力和生物质直燃等可再生能源发电产业。本文运用能值分析法,选取中国装机容量最大的浙江省江厦潮汐试验电站(4.1 MW)为案例,对其建设与运行的可持续性进行分析,并与其他可再生能源发电系统的相关指标进行平行对比。结果表明:2014年该发电系统投入的能值总量为5.08×1019sej,电力产出为2.61×1013J,其中可更新资源投入比例为17.77%,能值转换率为1.95×106sej·J~(-1);环境负载率(ELR)和能值可持续性指标(ESI)分别为4.63和0.12,可持续性表现较差;究其原因,潮汐能是一种更为分散的、低品质能量,其捕获、收集和品质提升需要投入较多的外部资源。研究结果也表明,在现有开发模式下,不鼓励潮汐能发电的大规模扩张与发展,强化技术研发、更新开发模式,将是未来实现高效、可持续利用丰富潮汐资源的必由之路。
[Abstract]:Although China has abundant tidal resources, the tidal power generation industry lags behind the renewable energy generation industry such as hydraulic, photovoltaic, wind and biomass direct combustion to a large extent. Taking Jiangxia Tidal Test Power Station of Zhejiang Province with the largest installed capacity in China as a case study, the sustainability of its construction and operation is analyzed. The results show that in 2014, the total energy input of the system is 5.08 脳 1019sej. The power output is 2.61 脳 1013J, in which the renewable resource input ratio is 17.77 and the emergy conversion rate is 1.95 脳 106sej. The environmental load rate (ELR) and the emergy sustainability index (ESI) were 4.63 and 0.12, respectively. The reason is that tidal energy is a more dispersed, low-quality energy, its capture, collection and quality improvement need to invest more external resources. The results also show that under the existing development model. It is the only way to realize high efficiency and sustainable utilization of rich tidal resources in the future by not encouraging the large-scale expansion and development of tidal power generation, strengthening the research and development of technology and renewing the development mode.
