摘　　要：应用判别式法求解大规模梯级水电站库群发电优化调度问题,以便能够直观反映梯级水电站系统的运行规律.为解决方程组求解带来的困难,采用坐标轮换法,将多库同时供、蓄水决策转化为单库逐次轮换决策,并结合水库常规调度图规则,对判别式法进行修正,使求解结果更为合理.结合乌江流域梯级水电站调度系统,给出了一个在梯级系统保证出力约束条件下发电量最大的实际例证.Discriminant method was introduced to solve the large-scale hydropower-scheduling problems. It can reflect the running rules of hydroelectric stations directly. In order to solve difficulties of calculation of equation groups, the coordinate transmigration method was adopted. The store or purvey quantity of water decision-making from malti-reservoir can be translated simultaneously to single reservoir step by step. On the basis of the routine operation chart of hydropower station, the discriminant method was improved and the result was reasonable. In combination with the Wujiang cascaded hydroelectric stations system, an example of maximizing the energy was given.
