In　order　to　overcome　the　defects　of　existing　methods　on　monitoring　and　warning　of　the　wild　fire　near　transmission　lines,　such　as　satellite　and　image　monitoring,　an　automatic　identification　algorithm　of　wild　fire　near　transmission　lines　based　on　the　CINRAD-net　monitoring　was　proposed　in　this　paper.　According　to　a　sample　database　of　CINRAD　echoes　for　historical　wild　fires　in　a　certain　area,　the　characteristics　of　the　CINRAD　echoes　for　wild　fire　were　analyzed.　Thereby,　the　features　characterizing　CINRAD　echoes　were　constructed　and　the　threshold　criteria　were　given.　Then,　the　four-neighborhood　algorithm　was　used　to　automatically　identify　the　wild　fire,　and　the　radar　clutter　was　filtered　to　improve　the　identifying　accuracy.　Combined　with　multithread　processing　method,　the　automatic　identification　for　wild　fire　was　realized.　Based　on　an　improved　tower　location　method,　fast　locating　and　warning　of　wild　fire　were　achieved　for　transmission　line　towers.　The　application　in　a　provincial　power　grid　has　showed　that　the　proposed　method　has　an　identification　accuracy　of　nearly　80%　in　sunny　days.　This　paper　provided　a　new　way　for　monitoring　and　warning　of　the　wild　fire　near　transmission　lines,　which　can　be　verification　and　a　supplement　for　satellite　monitoring　method.　©　2020　Chin.　Soc.　for　Elec.　Eng.
