Research On Graphical Interfaces Automatic Model Constructing In Hydro-mechanical Transient

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.
