The Research And Development Of Graphic Electric Power System Computing Based On Visio

With the development of the electrical power enterprise and computer technology, It is important to design a highly efficient, better maintainable and graphic interface based software package for power system analysis and computing.With the development of optimization techniques and the use of computers during last two decades, many power system software came into use, which have changed the situation of handwork, improved the work efficiency greatly and relieved workers from heavy work burden. However, the fast development of computer technology and Internet makes the software no longer meet the need of today's power system computing work. We considered the deficiency of the software at present and utilize Visio to develop the practical graphic power system calculating software from many references to research results of power system calculation and relevant graphic software. Main works as following.1. Set up platform frame of the graph, design the basic model of electric component, and realize the design of object-oriented component data structure. This software has realized a great deal of graphic editing function, and can draw and edit network geographic connect and electrical connect graph on software platform.2. Utilizing the characteristic of Visio, carry on the automatic serial number to the component, discern the topological structure of the electrical network automatically, realize the input and setting of the parameter in the graph. It utilizes strong secondary development function of Microsoft Visio and regards ShapeSheet tables as contact of every graph and the background VBA macro, then forms the library of the components and makes components library correspond to ShapeSheet tables.3. Utilizing VBA editing machine of Visio, finish the establishment of calculating module, compile power flow and short circuit module. This software can label every result of calculation in the graph, and can combine the result of calculation and excel, form beautiful, standard calculation report forms.In sum, this software has strong adaptability, good reusable and expanding, can provide automatic and intelligent calculations, and is also helpful in the everyday maintenance and facilitates the system administration. At the same time, this software...
