Abstract

Abstract: Transient process is the basis of the safe and stable operation of hydropower station. The calculation of transient process is realized by professional numerical simulation software. This paper presents the research and development of the visual numerical simulation software for transient process of hydropower station. The software is designed and developed based on the Java language and the Eclipse and IntelliJ IDEA development environment. The research and development thought contains five aspects. Firstly, the mathematical model for the transient process of hydropower station is established and the algorithm is adopted. The program for numerical simulation is designed. Secondly, based on the modularization design principle, the object modules and operating condition modules are designed and encapsulated. Thirdly, the user-oriented visual interface of the software is designed and programmed. The visual interface includes menu bar, toolbar and plotting area, which realize the drawing of topology of hydropower station, input of parameters, setting of calculation conditions and post-processing of calculation results. Fourthly, the foreground and background interaction based on graphic interface is achieved to realize the recognition of topology, automatic coding of object modules and transfer of foreground data. Finally, the mathematical model, algorithm, object modules, operating condition modules, visual interface and foreground and background interaction are integrated and the development of the visual numerical simulation software is completed. The visual numerical simulation software for transient process of hydropower station is a general software and has a friendly user interface. Test and application of practical engineering prove the correctness, reliability and precision of the software. The visual numerical simulation software provides a simple, practical and efficient tool for the calculation of transient process of hydropower station.
