摘　　要：针对水能利用提高率考核水电站调度管理水平中存在的片面性和季调节能力以下电站考核水位原有取定方法的缺陷,增加了理论电量完成率考核指标,提出了季调节能力以下电站考核水位根据来水丰枯级别采用分级系数进行动态设定的改进方法。实例计算表明,新考核指标及计算方法实现了对电站调度工作已取得成就和可开发潜力的综合评价,对实际生产具有较高的指导意义。Aiming at decreasing the influence of one-sidedness of waterpower utilization improving ratio examine on dispatching management of hydropower station and drawback of traditional fixed way of assessment water level for seasonal or less seasonal hydropower stations, a theoretical power completion rate index is added and it proposes a new way that it could dynamically set an assessment water level according to the level of annual runoff by plentiful and withered classified coefficient. The case study shows that it realized a comprehensive assessment of dispatching management and water-saving additional power generation capacity and it has an instructive significance for plant scheduling.
