摘要
Abstract
Lightning activities in Guangzhou area are frequent,but there is only one detection station without a central station.Thus,lightning detection efficiency and location precision are both poor,which can not satisfy requirement for lightning fault location.Therefore,Guangdong power grid co.,ltd.starts construction of a new generation lightning location system from 2012 and has finished constructing the new generation location system covering five detection stations in 2013.Meanwhile,it has accomplished interconnection with the lightning location system of CSG.The new system after interconnection has been greatly improved in detection efficiency and location precision,and it has a central station which is able to realize measurement and statistics for critical parameters such as lightning frequency and lightning current amplitude.The new system has been used for statistics and analysis on lightning activities in Guangzhou area in 2015 and 2016.By comparing lightning tripping data of transmission lines in 2016,differences of three lightning location systems in location precision and detection efficiencies are analyzed.Results show detection efficiency of the new interconnected system is 91.4％ which has been improved by17％ higher than the old system,and the average location precision of the new system is 592.52 m which has been promoted by 34％ higher than the average location precision of the old system.关键词
