摘要
基于层次分析法(AnalyticHierarchyProcess,AHP)的基本原理,建立了一个用于评估输电线路防雷措施的层次分析结构模型,以某220kV实际线路为例对各种措施进行综合评估和计算,得到了该线路防雷改造方案的优先次序:降低接地电阻、架设耦合地线、增加避雷线根数、安装线路型避雷器、增加两片绝缘子。
Based on the fundamental principle of analytic hierarchy process (AHP), the hierarchical structural model for lightning evaluation of transmission lines is established, With a practical 220kV transmission line as an example, several lightning protection measures are evaluated and calculated, the priority orders of the measures for the lightning protection renovation of this transmission line are as follows: reducing grounding resistance, erecting coupling earth wire, increasing the number of overhead ground wires, installing line lightning arresters and adding two pieces of insulators, etc.
