Research On Visualization Of Power System

With the development of power system, its operating state is more and more complex. The operators need to deal with a great deal of data, whose tasks are heavy. With the improving of the application software of energy management system (EMS) and the increasing of the computer calculating speed, kinds of results come into being. The development of power system brings a great deal of economic data. The present method of displaying data cannot be satisfactory. So a good way is needed to display the data so as to improve the operators' working efficiency.The visualization technology is a new research domain with the developing of the computer technology at the end of the 1980s. It is used to analyze and deal with an immense amount of information and to improve working efficiency.This paper carries through a deep research on the display of data in power system combining the visualization technology and computer technology, and has successfully designed the visualization software of data in power system. The system is designed regarding Windows XP as operation system, and Visual C++ 6.0 as developing tool, and SQL Server 2000 as database. The system have the characteristic of modularization, and have universal property, its planning idea is object - oriented technology.This paper mainly illustrates the design progress of the visualization technology and accomplishes the overall structure of the visualization software of data according to the features and requirements of power system, and makes out the composing modules and the relationships between them; The system is divided into two parts: configuring platform and running platform; Then the paper focuses on the key techniques used in each part of the system emphasizing the Object-Oriented technique, graph technique and database technique.Graph technique is mainly used in the part of graph configuration. It mainly refers to drawing with GDI functions, and carries out the functions of collect, copy, paste and so on; At the aspect of database it manly introduces the knowledge of the view and database interface , and connects the data between the figure and database using ADO; Finally, the paper introduces the technique of data display, including the display of dynamic arrows, pie and three-dimension. Based on these visualizations technologies, visualizations in the power flow and bus voltage three-dimension are implemented. The characteristics of software are shown in concrete application combining with running example on IEEE 36.
