摘　　要：长江干流十几座在建、拟建的大型水电站将形成世界上最为庞大的梯级水电站群,其联合调度运行对我国能源安全、水资源安全具有重要的战略意义。本文将传统调度图方法和逐步优化数学模型相结合,构思了一种新的梯级水电站群联合调度的控制方式,并结合长江上游"龙头水库"兴建背景下的干流水电站群长系列调度中得到了应用和验证;分析了龙盘"龙头水库"方案对于下游梯级的电力电量补偿效益和对长江干流枯水期的水量补偿效益,通过不同"龙头水库"方案调度结果的敏感性分析揭示了不同调蓄库容对于综合补偿效益的影响规律;揭示了"龙头水库"兴建背景下三峡综合效益的变化规律,并对一般性流域采取"龙头—总控"的梯级水电站群开发模式进行了战略性思考。More than a dozen of huge cascaded hydropower stations are or will be under construction on the Yangtze mainstream, and as the largest hydropower system all over the world, its joint operation has important and strategic significance to China＇s energy security and water resources security. We have designed a new control scheme for such a hydropower system, combining traditional operation charts with a progressive optimization algorithm, and applied it to huge cascaded reservoirs on this river that will be in joint operation with the leading reservoir under construction to verify its performance. This paper describes this scheme and its application results, and analyzes the benefits of leading reservoir in its compensation to the power generation of the hydropower cascades and the mainstream water resources in low water season. We also demonstrate variation trends in comprehensive compensation benefits that depend on the storage of leading reservoir through sensitivity analysis, including a trend in the comprehensive benefits of the Three Gorges reservoir under the construction of leading reservoir. Strategic thinking that how to develop the leading and controlling cascaded reservoirs for a general valley, is also suggested.
