摘　　要：建立了一种基于双启动标准的限制供水解析规则.新规则由3个子规则组成,并考虑了未来潜在缺水量与当前可利用水量的关系.首先通过时段初蓄水量与时段末两级目标蓄水量的关系决定潜在缺水量,从而确定调用何种子规则;然后在每个子规则中,根据当前可利用水量决定是否启动限制供水.从理论上给出了新规则的解析表达式,同时采用主-从种群混合进化的粒子群算法优化规则参数.徐家河水库供水调度的实例研究表明:新规则具有一定的合理性和有效性,结果明显优于标准运行策略、调度图以及常规连续型限制供水规则.A analytical hedging rule based on a double triggering mechanism was proposed.The new rule was composed of three sub-rules and considered the relationship between potential water shortage and water availability.First,the sub-hedging rule was invoked based on the relationship between initial storage and rule curves.When to start hedging was then decided by the current water availability in each sub rule.The proposed rule was analytically derived and the parameters on hedging were optimized by serial master-slaver swarms shuffling evolution algorithm based on particle swarm optimization.The Xujiahe reservoir was employed as a case study to verify the efficiency of the proposed rule.The operation results show that the proposed rule is more effective and reasonable to handle water supply operation problems,compared with the standard operation policy and conventional hedging rules.
