摘　　要：雷电是影响输电线路稳定运行的关键环境因素,精准掌握输电线路雷击跳闸率对电网可靠运行具有重要意义。本文基于海南电网线路跳闸数据、地理环境信息数据和杆塔数据,通过关联规则和CRITIC法分别计算海拔高度、坡度、坡向、坡位、经度、纬度、土地类型等7个地理环境特征和电压等级、杆塔的型号、根开、呼高、导线弧垂、地线弧垂、档距、接地电阻等8个杆塔特征与雷击跳闸的关联关系,并揭示各参数的权重大小,得出海南电网输电线路雷击跳闸率计算关键参数,为线路的雷击风险评估提供支撑。Lightning is a key environmental factor affecting the safe and stable operation of transmission lines,and accurately grasping the lightning-induced trip rate of power transmission lines is of great significance for the reliable operation of the power grid.This paper is based on the trip data,geographic environment information data,and pole-tower data of the Hainan power grid.By using association rules and the CRITIC method,the correlation between 7 geographical environmental characteristics such as altitude,slope,slope direction,slope position,longitude,latitude,and land type,and 8 pole-tower characteristics such as voltage level,pole-tower model,root opening,height,conductor sag,ground wire sag,span,and grounding resistance,with lightning-induced trips is calculated.The weight of each parameter is revealed,and the key parameters for calculating the lightning-induced trip rate of power transmission lines in the Hainan power grid are derived.This provides support for the assessment of lightning strike risks along the lines.
