地区电网图形化综合故障分析与继电保护测试软件研究

Research on software for graphic integrated fault analysis and relay protection test for district power grid

从现代地区电网的特点和需求出发,研究了图形化综合故障分析与继电保护测试软件的开发。软件依靠面向对象技术,采用图形数据一体化建模,具备了计及线路互感的多重复杂故障计算等功能,并在网络环境下进行数据共享。同时,将故障分析结果通过接口程序与继电保护测试仪相连,并接上实际的保护装置,实现了基于综合故障分析的继电保护动作测试。该软件已经投入实际使用。

According to features and requirements of modern district power grid, the development of software for graphic integrated fault analysis and relay protection test is researched. Based on object -oriented technology and integrative modeling of graph and data,the software has the function of complicated multi- fault calculation,considering mutual- inductance of lines,and realizes data sharing under network environment. Fault analysis results are sent to relay protection test device via interface program. The actual relay protection is connected with the test device and tested according to the integrated fault analysis results. The software has been put into operation.
