| The Electric Power Network Simulation System(EPNSS) is a software which can be used as a training system or be used to appraise the disaster reaction. It has a same function process with the electric power network control system. The difference between them lies in that the basic data in the Simulation system could be collected from control system, and could be modified or saved as a case.With the increasing of the requirements, the quantity of electric power devices is also increasing. In the system, how to get the information of target devices is getting more and more important.In most electric power network control systems, the service processing server and console server are usually be constructed under UNIX/LINUX operation system, and using X Windows as the main display measure.Motif is a standard library on graphical user interface, which is designed by the Open Software Foundation (OSF). It has been widely used in most UNIX systems. It's an industrial strength toolkit based on X Toolkit, and is very useful in developing the user interface application in industry software. Motif is high remarkable with efficiency, reusability, and transferability.By analyzing the composition of existing device database, the thesis designs a mode which could make the devices'data to adapt the EPNSS, presenting the concept of electric power device database inquiry system. To diverse the inquiry method, the more convenient user experience as the goal, by separating the user interface and function processing, function processing and object data, so that the version update and the crosswise transplant could be more convenient. The thesis unified Motif's characteristic, completed the system outline design under the OSF/Motif platform. Finally, the device database inquiry system has being realized. By using the software, the efficiency of data modify and reference was remarkably enhanced, and as an outstanding software, it has be transplanted to other electrical power systems. |
