浙南水电增效扩容与绿色改造研究

Research and planning on efficiency increase, capacity expansion and green transformation of hydropower in Southern Zhejiang

摘要

我国小水电资源丰富，自20世纪80年代起，国务院大力推进农村水电建设，成功建成1 500多个电气化县，全国小水电站总装机容量超过73 000 MW,占据着世界各国小水电装机容量的半壁江山，显著推动了农村经济和社会发展。然而，随着经济发展和环保意识提升，小水电的作用逐渐被边缘化，存在的历史问题尚未有效解决。基于我国农村水电基础数据平台，探讨了小水电绿色改造和现代化提升的可行性，分析了在高比例新能源并网条件下的水电扩建模式及混合抽蓄改造的可行性，提出了浙南水电资源富集区的改造规划方案，并对不同规模水电站的技术经济性进行了分析。研究表明，通过合理的增效扩容改造，老旧水电站可以显著提高能效，增加发电量，并改善安全性和环境效益。

Abstract

China is endowed with a substantial reservoir of small hydropower resources. Since the 1980 s, the State Council has been instrumental in the advancement of rural hydropower development, successfully completing the electrification of over 1 500 counties. The country's installed capacity of small hydropower stations has reached a remarkable 73 000 megawatts(MW), representing over half of the global installed capacity of small hydropower. This achievement has significantly contributed to the economic and social advancement of rural areas. Nevertheless, as a consequence of economic development and environmental awareness, the role of small hydropower has been gradually marginalized, and the existing historical problems have not been effectively solved. A basic data platform of rural hydropower in China is employed to explore the feasibility of green transformation, modernization, and upgrading of small hydropower.It also analyzes the hydropower expansion mode and the feasibility of hybrid pumping and storage transformation under the condition of a high proportion of new energy to the grid. Furthermore, it puts forward a transformation planning plan for the hydropower resource-rich area of Southern Zhejiang Province and analyzes the technical economics of hydropower stations of different scales. It is demonstrated that through the implementation of reasonable efficiency enhancements and expansion renovations, the aged hydropower station can markedly enhance its energy efficiency, augment its power generation capacity, and enhance its safety and environmental benefits.
