摘要(Abstract)：

针对传统故障计算软件在人机交互界面、数据库的连接访问速度及程序的运行效率等方面存在的不足,并且不能计算复杂故障等问题,介绍一种以多端口理论和通用边界条件为基础开发出的可视化电力系统复杂故障计算软件。该软件采用Delphi和Fortran混合编制技术以及利用先进的COM组件技术对故障计算程序进行封装集成,利用ActiveX数据对象(ADO)组件动态连接技术开发而成,实现了故障计算模块和人机界面的无缝连接。软件界面友好、操作方便、数据交换快速、计算高效准确。经地区电网工程实际应用,效果良好,具有很好的应用前景和实用价值。
Fault calculation is an important part of power system analysis and calculation. In traditional fault calculation software there are some shortcomings in aspect of man-machine interface,the speed of database linking and visiting,and running speed of the software. Moreover,they can not perform the complex fault calculation. In order to solve these problems,a visual power system complex fault calculating software was designed. It realizes the complex fault calculation by multiple-port theory and generalized fault boundary conditions. The Delphi language is used to design the interface of software and Fortran language is used to develop fault calculating program. In addition,it implements the seamless connection between the fault calculating module and man-machine interface by using the advanced COM component technique to integrate the fault calculating program. Moreover,in order to exchange data rapidly,it utilizes the ActiveX Data Objects (ADO) component to link the background database dynamically. These advanced techniques make the interface friendly,operation easily,calculation efficiently and accurately. The application of this software in region power system shows that it is effective,promising and valuable.
