【摘要】 万家寨引黄工程是国内最大、具有国际先进水平的封闭式引水工程。该工程所处地域地形复杂，属大流量、长管道、高扬程、多级泵站串联运行的封闭式大型引水工程，沿线调蓄能力差，运行工况复杂。本文在引黄工程全系统分析的基础上，以面向对象的分析和设计方法，设计了水力学仿真系统的对象模型；建立了泵系统、管道和阀门的水力学仿真计算的数学模型。在此基础上，给出了管道、泵系统数值计算和阀门关闭曲线的抛物线插值算法的流程。 在Windows XP环境下，以上述仿真计算模型和算法为基础，使用Visual basic语言，编程实现了引黄工程从总干万家寨水库至申同嘴水库水利学仿真计算程序，对总一、二级泵站的多种运行工况的水力学瞬变特征进行了仿真计算。 理论分析和实际仿真计算结果表明，本文所采用的数学模型及数值计算方法是可靠的。因此计算得到的系统特性是精确可靠的，并且与实际发生的工况基本吻合。更多还原

【Abstract】 The Wanjiazhai Yellow River Diversion Project (YRDP) is the biggest on scale in China and the most advanced close diversion project on earth as well, which is big flow, long tunnel, high head serially close large-scale diversion project and has low ability to adjust and save with complex running conditions. This paper puts forward the object models of the hydraulics computer simulation system on the basis of object-oriented system analysis and design as well as the whole-system analysis of YRDP. At the same time, system designs and creates the hydraulics mathematical models in terms of its pump system, conduit and valve. On this base, put forward the flow of numerical calculation of the conduits and pump system, and the flow of parabola-insertion algorithm, on which the value of the midst point on the valve-closed curve can be calculated.On the platform of Windows XP, depending on the model of the hydraulics computer simulation and the algorithm, aiming at the General Main Pump Station(GMPS) of YRDP, from Wanjiazhai reservoir to Shentongzui reservoir, the hydraulics computer simulation program has been programmed and implemented with MS VB 6.0, which is able to simulate the hydraulics characteristics of a series of transient working conditions between GMPS1 and GMPS2 of YRDP.Theoretical analysis an practical numerical calculation result indicatethat mathematical models and numerical calculation methods in the paper is exactly reliable. So the characteristics of system are exactly reliable by calculation. And it tallied with the actual working conditions of the system.更多还原
