摘要
利用EMTP电磁暂态仿真软件,对某800 k V GIS系统中的快速暂态过电压进行仿真计算,得到系统在不同操作方式下,各个节点上VFTO的幅值大小,其值为1~2 p.u.。同时,利用MATLAB得到各个节点上VFTO的频谱图,并对其各自的波形进行简单分析。最后,利用得到的仿真结果分析了VFTO的影响因素。
This article makes simulation calculation using the EMTP electromagnetic transient software with a 800 kV GIS system about the Very Fast Transient Over-voltage. The obtained result shows the VFTO amplitudes of all the nodes in the system under different op- erating modes which are with a value between 1 to 2 p. u.. Meanwhile, the VFTO spectrum diagrams of every node are gained by using of MATLAB and the diagrams are made a simple analysis on their respective waveform.
