【摘要】 水力—机械过渡过程对水电站的安全性和经济性均有重要意义，其计算软件的研发也一直是水电工程界的热点问题。但由于受软件开发环境、开发平台等条件的限制，目前开发出来的大部分软件在通用性、易修改性、易校对性方面都有待提高。本文根据自动形成水力—机械过渡过程数学模型软件的研究现状，着眼于有压过水系统的主要结构形式，借鉴相关软件的开发经验，研制开发了一套基于图形界面的自动形成水力—机械过渡过程数学模型应用软件。主要研究内容如下： 1．在分析水电站水力—机械过渡过程的主要数学模型和计算方法的基础上，研究了有压引水系统数学模型的特点和共性，提出了拟开发的具有图形界面自动建模软件，该软件具有通用性强、易校对性、易修改性、界面友好等特点和要求。 2．根据图形化自动形成有压过水系统数学模型仿真软件的开发要求，对比现有的程序开发环境、开发平台和开发工具，根据实际需要，采用visual Basic开发本软件，并介绍了软件开发技术路线。 3．详细论述图形化自动建模软件的设计方法、软件结构、相关的数据结构、算法、关键技术及界面制作途径。 4．举出实例，根据软件开发要求，对用图形界面形成的有压过水系统进行修改，然后输出相关数据文件，对比两个修改前后的模型之间的差异，验证软件开发的正确性。更多还原

【Abstract】 Study of hydro-mechanical transient is crucial in design and operation of hydroelectric power plant and the development of computation software is always the hot point in hydroelectric engineering field. But because of the constraint of software develop environment, platforms etc, most of the software developed recently have some difficulties in aspects such as generality and modifiability, which are to be improved. Based on the status of research on the software now existing, the author has developed a graphical interfaces based software which can form automatically hydro-mechanical transient, computation model for hydroelectric power plant with different water conveying system. Main research points are as follows:1. Analyzing the main mathematical models and computation methods of hydro-mechanical transient, characteristics and commonness of the mathematical models of water conveying are discussed, and characteristics of the graphical interfaces based-automatic model constructing software such as generality, modifiability, user friendly interface are proposed.2. Based on the requirement of software development and comparison of the software develop environment, platforms and tools, the feasibility of using Visual Basic to develop the software and the technical route of software development are confirmed.3. The design methods, software structure, related data structures, algorithms and key technology in the implementation of the software and interfaces are discussed.4. The software has been used for a project to form and modify computation model of hydro-mechanical transient, and the correctness of the software is confirmed. The results show that the objectives proposed above are achieved.更多还原
