概述葛洲坝水力发电厂是低水头径流式电站,额定水头为H_N=18.6m。设计最小水头h_(min)=8.3m,最大水头H_(max)=27m,水头变化范围的百分数为:(H_(max)-H_(min))/H_N×100％=100.5％。到目前为止,实际运行的最小水头H_(min)=8.63m,对应导叶空载开度α_(max)=35％,最大水头H′_(max)=26.29m,对应导叶空载开度α_(min)=10％,水头实际变化范围的百分数为:(H′_(max)-H′_(mix))/H_N×100％=95％,导叶空载开度的
Overview Gezhouba Hydropower Plant is a low head runoff power station with a rated head of H_N = 18.6m. The minimum design head h_ (min) = 8.3m, the maximum head H_ (max) = 27m, the percentage of head change range: (H_ (max) -H_ (min)) / H_N × 100% = 100.5%. So far, the actual minimum head H min = 8.63 m corresponds to the guide vane opening α max = 35% and the maximum head H max _ 26.29 m, corresponding to the guide vane open Degree α min (min) = 10%, the percentage of the actual range of the head is: (H ’_ (max) -H’ _ (mix)) / H_N × 100% = 95%
