Abstract
In allusion to deficiency of pertinence of using lightning positioning system for evaluating lightning protection,and intelligent fault diagnosis system of distributed powertransmission line being only able to monitoring lightning action of pow-er transmission line corridor while unable to record lightning direct stroke lines,a kind of new evaluation method for light-ning protection was proposed based on integrated application of intelligent fault diagnosis system and lightning positioning system.This method uses lightning stroke frequentness acquired from lightning stroke monitoring data of intelligent fault di-agnosis system and lightning positioning system to calculate shielding failure trip-out rate and back-strike switching rate of the tower,then to divide easily stroke sections of shielding and back-strike according to trip-out rates in order to make point-ed references in developing differentiation lightning protection transformation works.Actual measuring lightning data of some evaluation case was used for evaluating technical transformation effect of lightning protection and the result indicated that this method could used for effectiveness evaluation on lightning protection measures in short time,forming closed-loop control on evaluation on lightning protection transformation measures and effects and promoting veracity of evaluation anal-ysis on lightning protection and economy of lightning protection transformation.关键词
