摘　　要：混合式抽水蓄能水电站水库入库为混合径流,包括抽水形成的人工径流和天然径流.混合径流是计算时段的平均指标,为分析该信息指标在混合式抽水蓄能电站水库长期调度水能计算中的准确性,在供水期以月为计算时段,比较基于混合径流的月电量计算和计及日内水位变化的月电量计算,并以白山混合式抽水蓄能电站为例进行计算,结果表明应用混合径流信息指标计算引起的数据误差很小,该信息指标有助于常规水电站水库长期调度方法在混合式抽水蓄能电站水库的应用.The mixed pumped-storage power plant＇s reservoir inflow is mixed runoff,which is made up of natural runoff and artificial pumped runoff due to reversible units＇ running.The mixed runoff of the mixed pumped-storage power plant＇s reservoir is an average index;and its accuracy must be verified for reservoir long-term operation＇s hydropower computation.Month electricity computations have two methods： One is based on mixed runoff;the other is based on daily upper level.Taking the Baishan Mixed Pumped-Storage Plant for example,the two methods are carried out.Results show the mixed runoff is suitable for the mixed pumped-storage plant＇s reservoir long-term operation with less error;and it contributes to general reservoir＇s operation methods applying to mixed pumped-storage power plant＇s reservoir long-term operation.
