摘要
针对三个梯级水电站出现的水量计算不平衡的现象 ,通过对这三个水电站的日常水情调度数据的分析和对库区河段的明渠非恒定流计算 ,探讨了水量计算不平衡的原因 ,并给出了这些水电站的水位流量关系特性 。
Aiming at the phenomenon of water quantity unb al ance in the calculation of three cascade hydropower stations, this paper discuss es the reason of water unbalance in the calculation and gives characteristics of relation between water level and discharge by analyzing daily water condition r egulation data of these hydropower stations and calculation of unsteady flow in open channel of reservoir-area river reaches of the three stations. These resul ts give some references for other cascade hydropower stations.
