基于发电量反推径流水能小水电装机复核研究
|
摘要
为准确掌握桑郎水电站增效扩容潜力,合理利用水能资源,文章采用清水河党家湾水文站1982—2015年34年径流资料,结合电站1999—2013年15年发电量数据反推引用流量,对径流水能特性进行详细复核研究。分析成果表明:通过水文站多年径流系列数据分析和发电量反推,电站扩容潜力较大,现状装机容量和机组性能与工程实际匹配性较差。通过合理装机方案更新改造,径流水能可以得到合理开发利用,且机组更新后水能转换效率得到提高,确保电站最大程度发挥发电效益。
Runoff data of Dangjiawan Hydrometric Station of Qingshui River from 1982 to 2015 and back-derived reference flow data of power generation data of the hydropower station from 1999 to 2013 are adopted to conduct detailed review and research on runoff hydroenergy characteristics in order to accurately grasp the potential of increasing efficiency and capacity expansion of Sanglang Hydropower Station and rationally utilize hydroenergy resources. The analysis results show that the power station has great potential for capacity expansion, and the current installed capacity and unit performance are poorly matched with the actual project through analysis on runoff series data of hydrometric station for many years and the back-derived of power generation. The runoff water energy can be developed and utilized reasonably through the renovation of the reasonable installation scheme, and the conversion efficiency of water energy can be improved after the unit is updated to ensure that the power station can give full play to its power generation benefits.
