变电站雷电侵入过电压计算图形软件开发应用
|
摘要
针对雷电直击输电线路引起的变电站侵入波过电压问题,在贝杰龙法的基础上基于.NET平台采用面向对象的C#编程语言,开发了一套Windows系统下的变电站侵入波过电压计算图形软件,并通过通用计算程序EMTP验证了该软件的正确性。该软件具有参数输入、过电压计算和结果输出管理等功能,利用该软件对某500 kV GIS变电站侵入波过电压计算,根据各电气设备上的过电压数值研究变电站防雷保护方案。结果表明,该软件具有数据处理高效、方便数值建模等特点。
Regarding to the over-voltage in substation induced by lightning striking transmission line,the Bergeron method is employed to develop a set of graphics modeling software via C# programming language on the.NET platform in Windows system. This software is for calculating lightning intruding wave induced overvolt-age in substation,and its correctness is verified by the general program EMTP. The software has the functions of parameter input,overvoltage calculation and output management. This software is used to calculate the over-voltage on each electrical equipment in a 500 kV GIS substation for the purpose of putting forward lightning pro-tection schemes of the substation,and the results show that the software has many advantages,such as high ef-ficiency and convenient numerical modeling.
