Research Of The Methods Of Electrical Parameters' Organization Based On Interactive Graphic System

As well known, interactive graphic software platform, which has been widely spread in almost every aspect in the calculation and analysis application of power system, can help us establish a standard, scientific and efficient management information system. Be different from common graphic software, interactive graphic system has not only to display the graph, but also to save the data to RAM and database, which belong to corresponding graphic elements. Therefore, we must arrange them into appropriate organization so that we can manage them effectively. This thesis, which starts from the model of the graphic element, has discussed how to organize the data in interactive graphic system. The following items are concerned:(1) Establish the data model of graphic element. Graphic element is the fundamental unit in interactive graphic system, which is abstract image of existed electrical equipment. All the parameters in graphic system can be planned as a whole in the data model.(2) Set up the memory structure of graphic elements in the way of fully object-oriented method, and the data structure of elements' manager as well. Apply the command mode into the graphic system, and has discussed how to change the descriptive way of graphic elements from objected-oriented mode to relative data model, so that we can store the data for longer use.(3) Has discussed the method to integrate the graphic data and the attributive data into a whole entity, which is the key problem in interactive graphic system, from an electrical engineering point of view, and the specific way to realize it.
