【摘要】 跨流域调水是21世纪中国水利的一大特点,本文分析了调水工程水力控制的现状及发展状况,研究了长距离调水工程水力控制模型和神经网络理论在该领域的应用。 本论文的主要研究内容和研究成果有: ● 通过研究明渠水力瞬变的数学描述,提出了新的适用于明渠动态特性的线性化数学模型; ● 研究了描述管道、前池和水泵水力特征的线性数学模型; ● 分析了变速泵控制前池水位的自动调节系统,建立其控制调节的数学模型; ● 采用MATLAB中Simulink作为仿真工具,建立了调水工程水力控制的面向对象可视化仿真模型; ● 尝试把神经网络理论引入到调水工程水力控制领域,以优化系统调节的动态品质。

【Abstract】 Interbasin diversion is an important strategy of China in 21st century. Through analyzing the development, present situation and trend of this field, this paper provides a new hydraulic control model for water diversion projects and introduces the Artificial Neural Network to optimize the performances of the controlled systems.This paper includes the following works: Propose a linear numerical model adapting to the dynamic characteristics of open channels through theoretical research. Give a linear numerical model oriented to hydraulic characteristics of pipe system, upper pool and pump. Investigate the automatic control measures on regulating the upper pool water level by variable speed pumps. Build an object oriented visual model for the hydraulic control of water diversion projects, based upon Simulink toolbox of MATLAB. Introduce Artificial Neural Network to the hydraulic control field to optimize the performances of the controlled systems.
