提出并研究了一种基于Microsoft Visio2003图形软件的,利用VBA进行二次开发的图形化电力系统不对称单一故障及复杂故障计算软件开发的新技术和新的实现方法。研究了基于所绘电气接线图的电力系统通用的图形化建模方法,以及电网拓扑结构的自动识别。开发了运行于Visio2003的实用的电力系统图形化故障计算软件。开发实践表明,Visio的二次开发技术为图形化电力系统故障计算软件的开发提供了新的有效的途径。
A new technology and a new method for the development of asymmetric single fault and complex fault calculation software of graphic power system based on Microsoft Visio2003 graphics software based on VBA are proposed and studied. The graphical modeling method of power system based on the drawn electrical wiring diagram and the automatic identification of power network topology are studied. Developed a practical power system graphical fault calculation software running on Visio2003. Development practice shows that Visio’s secondary development technology provides a new and effective way for the development of graphical power system fault calculation software.
