基于图形界面的电力系统短路计算

Short Circuit Current Calculation of Power System Based on Graphic Interface

介绍了一种基于图形界面的电力系统短路计算软件。利用面向对象技术,实现了电网图形编辑器及电网拓扑数据库和参数数据库的形成,并且在图形上直接进行故障设置,软件能自动计算出故障位置,计算出结果。计算结果能直接在图形上显示出来也能保存在数据库中,便于结果的理解与查找。该软件采用Visual C++的MFC编程环境来实现电力系统的故障计算,人机界面友好,使用方便。

In this paper, a graphic interface based software for the short circuit current calculation of power system is introduced. It makes use of object-oriented technology to achieve the graphic editor for power network and the formation of topology database and parameter database for power network. When a fault is set on the graph directly, the software can automatically calculate the position of the fault, and calculate the result. The result can be displayed on the graph directly or saved in database, which is convenient for understanding and finding the result. The software uses the MFC environment of Visual C ＋ ＋ to implement power system fault calculation, and has friendly man-machine interface and is convenient in use.
