中文摘要：
针对多年调节水库年末控制水位的优选问题,在分析其年发电量与年末库蓄能量关系的基础上,建立了兼顾多年调节电站装机容量效益的年末控制水位多目标预测模型,并以黄河上游龙羊峡水库为例进行了验证。通过入库径流、年初起调水位对年末控制水位的影响分析,揭示了多年调节水库年末控制水位优选的本质。实例计算结果表明,龙羊峡水库2006年之后的运行方式相对之前,已经有了较明显的改善,提高很大,同时也说明新模型合理有效,可用于指导生产实践。
英文摘要：
Based on the relationship between annual power generation and year-end energy storage, a multi-objective prediction model for the optimal year-end water level ot carryover storage reservoir is developed, which gives a full consideration to maximizing the hydro energy and least output of the hydro plant at such a reservoir. The model was validated with the case of Longyangxia reservoir on the upper Yellow, and the essence in obtaining its optimal year-end level was revealed through analysis of the impacts of water inflow and year-start level on this optimal level. The operation results simulated by the model are further compared with the prototype operation case of this reservoir from 1990 to 2012. This shows that since 2006 it has run at a higher level than before 2006, which improves its own benefits and indicates that the multi-objective model is reasonable and feasible.
