雷电被认为是架空配电网故障的主要原因之一。由于使用的绝缘水平，直接中风通常会导致闪络。由间接雷击引起的感应过电压通常较低，金属氧化物避雷器可以有效地降低感应过电压。因此，其相关的闪络率可以降低。本文提出了一种启发式方法来优化避雷器的数量以及它们的位置。该方法以遗传算法为基础，通过评估绝缘闪络的费用，从经济角度考虑。
Lightning is considered one of the main causes of faults in overhead distribution networks. Direct strokes usually lead to flashovers due to the insulation levels that are used. Induced overvoltages caused by indirect lightning are usually lower and can be efficiently reduced by metal-oxide surge arresters. Hence, its associated flashover rate can be reduced. In this paper, a heuristic method is proposed to optimize the number of surge arresters as well as their locations. The method presented is based on genetic algorithms and an economic approach is taken into account by means of evaluating the cost of insulation flashover.
