考虑先导电流的架空输电线路雷电反击研究

open access: yesDianci bileiqi
先导发展法作为架空输电线路耐雷水平计算中绝缘子串闪络的判据之一,在国内外已经获得广泛应用。在先导通道的建立过程中,会有大量电荷在先导通道中积聚,可以等效为流过放电通道的先导电流,一般认为该先导电流和先导发展速度成正比。但目前基于先导发展法的绝缘子串闪络计算中通常忽略了先导电流。基于CIGRE推荐公式计算先导发展速度和先导电流,在EMTP/ATP中采用可控时变电阻、TACS可控开关、MODEL模块建立了考虑先导电流的绝缘子串闪络模型,开展了500 kV和110 kV架空输电线路反击耐雷水平和500 ...
