摘　　要：水库群联合调度规则最优性条件是科学制定水库群联合调度策略的理论基础,也是确定水库群蓄放水次序的重要依据。先确定水库群系统总供水量进而优化其在各个水库中的供水任务分配是水库群联合调度中最常见的做法,因而由总供水量确定规则和供水任务分配规则(蓄水量空间分布规则)构成的水库群联合调度规则也是最常见的调度规则。本文以并联水库群系统中这类调度规则为研究对象,采用库恩-塔克条件(K-T条件),给出了这类常用调度规则的最优性条件及其对应的时段可利用水量阈值范围,提出了水库蓄放水优先次序的划分标准。研究结果表明:由总供水量确定规则和蓄水量空间分布规则构成的水库群联合调度规则适用条件较差,而且仅当水库群系统中每个水库可利用水量与系统总可利用水量始终维持在给定的阈值范围内时,并联系统调度运行的最优性才能得到保障。The optimality conditions of operation rule are essential for the coordinated operation of multi-reservoir system. The purpose of this paper is to derive the optimality conditions of operation rule for parallel reservoir system,which is defined in terms of system-wide release rules and individual reservoir storage balancing functions,by using the K-T conditions to solve a two-period model. Specially,the applicable water availability of both parallel system and individual reservoir for the optimality conditions are given,and themain factors to determine the water supply priority of individual reservoir are specified. The theoretical re-sults show that both the total system water availability and individual reservoir water availability have to be restricted within a certain range,in order to guarantee the optimal operation of parallel reservoir system.
