Development of graphic fault analysis software in power system based on VisioVBA

A new technique and a new method of developing the asymmetric single fault and complex fault analysis software in power system are proposed and studied,which use Microsoft Visio2003 as development platform and VBA as secondary development tools.On basis of electrical connect graph drew,the generally used method of graphic modeling of power system and the automatically identification of power network topology structure,are studied.Finally,the practical graphic asymmetric single fault and complex fault analysis software in power system is developed,which is operated under Visio2003.By developing this software,it indicates that the technique of secondary development for Visio offers a new effective method for the development of the graphic fault analysis software in power system.
