【摘要】：水库调度是运用水库的调蓄能力,在保证坝体安全的前提下,对水库上游的天然洪水及径流进行有计划的蓄泄,以达到兴利除害、综合利用水资源、满足国民经济各部门需要的目的。水库调度的优劣不仅影响到大坝及下游人民的安全,更影响到水库蓄泄过程中产生的经济效益和社会效益。由于现今优化调度成为水库调度研究的一个热门方向,在此领域有了百花齐放的研究成果,但其优化模型复杂,数据采集量大,计算参数复杂多变,优化调度方案在调度实际中难以得到广泛应用。本文根据水库调度在调节计算过程中最常用的等流量调节计算方法,提出了动态适应性水库调度方法,结合知识可视化综合集成平台,构建了较为通用的动态适应性调度、评价管理系统,旨在通过计算机及可视化手段,快速计算生成调度方案,对水库调度决策者提供科学合理的帮助与指导。论文主要研究内容和成果如下:(1)动态适应性的调度方法研究。基于常规等流量调节计算方法,分析其中不足之处,对其进行改进,提出适应性水库调度方法。其适应性主要体现在:适应不同的调节周期,适应不同的来水过程,适应不同的供需过程,适应生态用水等其它约束条件,并可以对调度方案进行实时动态修正及人工调整。(2)调度方案的评价优选。系统的研究了水库调度方案评价的指标体系,并采用层次分析法与熵权法确定评价权重,运用集对分析法、模糊优选法、灰色关联分析法三种评价方法对调度方案进行评价优选。(3)动态适应性调度、评价管理系统研究及实例应用。基于知识可视化综合集成平台,通过实例仿真,对一般水库在调度过程中各种水量约束下,快速计算生成调度方案,并可以进行方案人工调整,结果以图、表的形式展示,过程可视可信,并具有较强的通用性;对多个调度方案进行多方法的综合评价,并对多评价结果进行组合评价,为水库调度过程提供了决策、协商和高效、可操作的综合系统。
[Abstract]:Reservoir operation is to use the ability of reservoir regulation and storage, under the premise of ensuring the safety of dam body, to store and drain the natural flood and runoff upstream of the reservoir, so as to achieve profit and eliminate damage and make comprehensive use of water resources. The purpose of meeting the needs of various departments of the national economy. The quality of reservoir operation not only affects the safety of dam and downstream people, but also affects the economic and social benefits produced in the process of reservoir storage and discharge. At present, optimal operation has become a hot research direction of reservoir operation, and there are a hundred flowers blooming research results in this field, but its optimization model is complex, the amount of data acquisition is large, and the calculation parameters are complex and changeable. The optimal scheduling scheme is difficult to be widely used in scheduling practice. According to the calculation method of equal flow regulation, which is the most commonly used method in the process of reservoir operation calculation, this paper puts forward the dynamic adaptive reservoir operation method, and constructs a more general dynamic adaptive operation method combined with the knowledge visualization integrated platform. The purpose of the evaluation management system is to quickly calculate and generate the dispatching scheme by means of computer and visualization, and to provide scientific and reasonable help and guidance to the reservoir dispatching decision makers. The main contents and achievements of this paper are as follows: (1) dynamic adaptive scheduling method. Based on the conventional equal flow regulation calculation method, the shortcomings are analyzed, and the adaptive reservoir operation method is put forward. Its adaptability is mainly reflected in: adapt to different adjustment cycles, adapt to different incoming water processes, adapt to different supply and demand processes, adapt to other constraints such as ecological water use, The real-time dynamic correction and manual adjustment of the scheduling scheme can be carried out. (2) the evaluation and optimization of the scheduling scheme. The index system of reservoir operation scheme evaluation is systematically studied, and the evaluation weight is determined by analytic hierarchy process (AHP) and entropy weight method, and the set pair analysis method and fuzzy optimization method are used. Three evaluation methods of grey relational analysis are used to evaluate and optimize the scheduling scheme. (3) dynamic adaptive scheduling, evaluation management system research and application. Based on the integrated platform of knowledge visualization and integration, through an example simulation, the dispatching scheme of the general reservoir is quickly calculated and generated under all kinds of water constraints in the dispatching process, and the scheme can be manually adjusted. The results are shown in the form of graphs and tables. The process can be trusted and has strong generality. The multi-method comprehensive evaluation of multiple dispatching schemes and the combined evaluation of multi-evaluation results provide a decision-making, negotiation and efficient and operable integrated system for reservoir operation process.
