【摘要】：随着我国最严格水资源管理制度的实施和水库梯级化流域化建设进程的推进,水库调度管理工作的重心逐渐由单一水库调度向复杂水库系统联合调度转变,迫切需要提出一套新的水库群联合优化调度理论体系与系统分析方法,以克服单库调度理论难以指导实际水库群联合调度运行的不足。基于此,论文以供水水库群联合调度规则表述形式及其最优性条件作为研究核心,以水资源系统中具有代表性的并联供水水库群和跨流域供水水库群作为研究对象,以两阶段调度模型与模拟-优化模型作为研究基础,以凸规划求解技术与智能优化技术作为研究方法,以开发模型最优求解算法和设计水库调度规则作为研究目的,开展了相关研究工作,具体包括以下三个方面内容：(1)水库群联合调度规则最优性条件是科学制定水库调度运行策略的理论基础,也是实际应用中确定水库群时段总供水量与蓄水量在不同水库间分配的重要依据。论文通过并联水库系统两阶段联合调度模型的建立与求解,提出了由确定时段总供水量的供水规则与蓄水量在不同水库间分配的空间分布规则组合构成并联供水水库联合调度规则的最优性条件,给出了符合该最优性条件的水库可利用水量运行区间,明确了水库蓄放水优先次序的划分标准,开发了并联供水水库两阶段调度问题的最优求解算法。辽宁省碧流河水库与英那河水库联合调度的结果表明,新算法显著改善了用水户缺水状况,提高了供水保证率,具有一定合理性与有效性。(2)水库群联合调度规则种类繁多、关系复杂,相互影响又相互制约,是水库调度研究的难点与焦点问题。论文以并联水库系统两阶段联合调度模型作为切入点,推导并给出了并联水库系统供水规则、分配水规则和蓄水量空间分布规则的解析表达式,探讨了由系统供水规则与蓄水量空间分布规则组合使用并联水库联合调度规则的适用条件。研究成果表明：新的分配水规则在一定程度上克服了现有并联水库调度规则系统性、适用性较差以及表述形式不统一的缺陷,同时明显优越于由限制供水规则(Hedging rule)确定时段总供水量和由参数式规则(Parametric rule)进行供水任务分配的组合调度规则。(3)跨流域供水水库群调水启动标准的合理性对于充分发挥调水工程在水资源配置方面的作用具有重要指导意义。针对现有调水启动标准未考虑水源水库蓄水状态的缺陷,论文构建了跨流域水库系统两阶段调度模型,推导了调水启动标准和水源水库可利用水量与受水水库可利用水量的函数关系,提出了一种由关于水源水库与受水水库蓄水状态综合判断条件构成的新调水启动标准。研究成果表明,新的启动标准更为充分地根据水源水库与受水水库的蓄水状态做出判断以确定给各个受水水库的适宜调水时机,较只考虑受水水库蓄水状态和在水源水库上采用统一的调水控制线的两种调水启动标准优越。论文拓展了两阶段调度模型的理论体系,给出了并联供水水库联合调度规则与跨流域供水水库群调水启动标准的最优性条件,探讨了现有供水水库群联合调度规则的适用性与局限性,开发了并联供水水库两阶段调度问题最优求解算法,设计了并联供水水库调度规则以及跨流域供水水库群调水启动标准,所取得研究成果不仅丰富了复杂水资源系统调度的理论体系,而且为水利工程的调度实践提供了技术支撑。
[Abstract]:With the implementation of the strictest water resources management system in China and the advancement of the cascade watershed construction process in the reservoir, the focus of the reservoir dispatching management is gradually changed from single reservoir to complex reservoir system. A new combined optimization and dispatching theory system and system analysis method is urgently needed. The single reservoir scheduling theory is difficult to guide the insufficiency of the actual reservoir group joint operation. Based on this, the paper takes the formulation of the joint dispatching rules of the water supply reservoir group and its optimality conditions as the research core, taking the representative parallel water supply reservoir and the cross flow field water supply reservoir group as the research object in the two stage. The scheduling model and the simulation optimization model are used as the research basis, the convex programming solution technology and the intelligent optimization technology are used as the research methods. In order to develop the optimal solution algorithm and the design of the reservoir scheduling rules as the research purpose, the relevant research work is carried out, including the following three aspects: (1) the optimal regulation of the reservoir group joint scheduling. The sexual condition is the theoretical basis for scientific formulation of the operation strategy of reservoir operation, and also an important basis for determining the distribution of the total water supply and the volume of water storage in different reservoirs in the actual application. Through the establishment and solution of the two stage joint dispatching model of the parallel reservoir system, the water supply rules for the total water supply in the period of time are proposed. The combination of spatial distribution rules for the distribution of water storage in different reservoirs constitutes the optimality conditions for the joint dispatching rules of the parallel water supply reservoir, and gives the operation interval of the available water for the reservoir. The dividing standard of the priority order of the reservoir water storage is clarified, and the two stage scheduling problem of the parallel water supply reservoir is opened. The optimal solution algorithm. The results of joint scheduling of Liaoning Bi Liu River Reservoir and the angna River Reservoir show that the new algorithm greatly improves the water shortage of the water users and improves the water supply guarantee rate. (2) the joint scheduling rules of the reservoir group are various, the relationship is complex, and the mutual influence is restricted to each other. It is a reservoir scheduling research. The paper takes the two stage joint dispatching model of parallel reservoir system as a breakthrough point, derives and gives the water supply rules of the parallel reservoir system, the distribution rules of water and the spatial distribution rules of the storage volume, and discusses the combination of the system water supply rules and the spatial distribution rules of the storage volume and the combination of parallel reservoirs. The research results show that the new distributive water rule overcomes the existing scheduling rules systematicness, poor applicability and inconsistency of expression forms, and is obviously superior to the total water supply of the limited water supply rule (Hedging rule) and the parameter rules (Parametr The IC rule) carries out the combined scheduling rules for the distribution of water supply tasks. (3) the rationality of the start standard of water diversion in the cross basin water supply reservoir is of great guiding significance to fully play the role of water diversion project in water resources allocation. The two stage scheduling model of the reservoir system is used to deduce the function relation between the starting standard of water diversion and the available water of the water source reservoir and the available water in the water reservoir. A new starting standard for water diversion is proposed, which is composed of the comprehensive judgment conditions of the water storage state of the water source reservoir and the water reservoir. The research results show that the new starting standard is more sufficient. According to the water storage status of the water source reservoir and the water receiving reservoir to determine the appropriate timing of water transfer to each water reservoir, two kinds of water transfer starting standards are superior to the water reservoir storage state and the unified water control line on the water source reservoir. The thesis extends the theoretical system of the two stage scheduling model and gives the theory. The joint dispatching rules of the joint water supply reservoir and the optimal conditions for the water diversion standard of the cross basin water supply reservoir group are discussed. The applicability and limitation of the joint dispatching rules of the existing water supply reservoirs are discussed. The optimal solution algorithm for the two stage scheduling problem of the parallel water supply reservoir is developed, and the scheduling rules of the combined water supply reservoir and the cross basin water supply are designed. The research results not only enrich the theoretical system of the scheduling of complex water resources system, but also provide technical support for the scheduling practice of water conservancy projects.
