日调节性能水电站节水增发电量考核方法研究

Assessment Method of Water-Saving and Power-Increasing Capacity of Hydropower Station's Daily Regulating Performance

通过对汉江上游流域不同调节性能水电站节水增发电量考核现状的分析,提出相对发电耗水率和水能利用提高率两个考核指标的概念,定义日调节性能水电站节水增发电量计算有关参数,制定节水增发电量计算流程;通过在汉江喜河水电站的实践应用对该研究进行数据分析验证,结果表明:基于日调节性能的水电站节水增发电量考核方法合理可行。

This paper analyses the assessment current situation of the hydropower station water-saving and power-increasing capacity with different regulating performance in the Hanjiang river upstream basin, puts forward two concepts of assessment index: water consumption for power generation and water energy utilization rate, defines the relevant calculating parameters of water-saving and power-increasing capacity of daily regulating performance of hydropower station, and establishes the water power calculation process of water-saving and power-increasing capacity. Data analysis and validation of the study are carried out through practical application of Xihe Hydropower Station on Hanjiang River. The results show that the assessment method of water-saving and power-increasing capacity of hydropower station based on the daily regulation performance is reasonable and feasible.
