生态环境需水量对芹山水电站发电效益的影响
Effect of eco-environmental water demand to on electricity benefit of Qinshan Hydropower Station
摘要
Abstract
Taking the Qinshan Hydropower Station as an example, the eeo-environmental water demand under different reliability scenarios of eeo-environmental water utilization was studied, the loss of power generation efficiency due to different eco-environmental water demand was estimated, and the effect of different proportions of eco-environmental water usage on hydroelectric power generation was analyzed.The results show that different methods, including 7Q10,Tennant, minimum monthly rtmoff, and NGPRP, generate different eco-enviroumental water demand estimates, and the differences are large because their starting point and basic principles are different.For this example, the method of Tennant was recommended.The generation schedules were compiled using the power generation dispatching software under different reliability scenarios of environment water usage, the loss of electricity benefit was estimated using the discharge year by year, and the relation between different reliability scenarios of environmental water usage and the loss of electricity benefit was analyzed.The relation between the loss of electricity benefit calculated using average annual flow and actual loss of power generation was also analyzed.关键词
