摘要
雷电电流幅值的概率分布对输电线路雷电性能的估计起着重要的作用。本文评估了代表San Salvatore山(Mount San Salvatore, MSS)和Morro do Cachimbo站(MCS)记录的闪电活动的闪电电流波的两个概率函数对230 kv输电线路反闪率的影响。采用可选暂态程序(ATP)计算产生的绝缘子过电压,并考虑破坏效应模型计算临界电流值和线路中断率。结果表明,根据临界电流水平的不同,所考虑的概率函数可能导致闪电性能估计的显著差异。
An Investigation into the Effect of the Probabilistic Distribution of Lightning Current Amplitude on a Transmission Line Backflashover Rate
Probability distributions of the lightning current amplitude plays an important role on the estimation of transmission lines lightning performance. In this paper, an assessment is made of the effect of two probability functions, related to lightning current waves representative of the lightning activity recorded at Mount San Salvatore (MSS) and Morro do Cachimbo Station (MCS), on the backflashover rate of a 230-kV transmission line. The Alternative Transient Program (ATP) is used to obtain the resulting overvoltages across line insulators and the disruptive effect model is taken into account to compute the critical current value and the line outage rate. The results show that, depending on the critical current level, the probability function considered may lead to significant differences in the lightning performance estimation.
