架空线—GIL混合系统短路电流分布特性研究

open access: yesGaoya dianqi, 2021
由于采用管道密封绝缘输电,GIL系统受地形、天气和外界环境干扰较小,采用架空线—GIL混合系统输电会变得越来越普遍。当混合系统短路故障时,其电流分布将异于正常输电线路。为了明晰混合系统短路电流分流问题,文中首先建立了架空线—GIL混合输电系统模型,通过开关闭合操作模拟设置输电侧导线发生接地短路故障,GIL管廊内三相导线电流的增强倍数在1.01~2.08倍之间,且当发生三相接地短路故障时的电流增强倍数最高;设置GIL管廊内部导线发生接地短路故障,GIL管廊内三相导线电流的增强倍数在1.05~21 ...
