In　the　paper,　the　complete　lightning　model　for　HVDC　transmission　lines　is　presented,　and　the　model　is　divided　into　five　parts:　lightning　discharging　model,　insulator　string　flashover　model,　arrester　model,　tower　model　and　conductor/ground　wires　model.　The　proposed　lightning　model　was　successfully　tested　in　the　PSCAD/EMTDC　software.　And　the　model　is　shown　to　be　a　potential　tool　for　studying　on　lightning　disturbance　identification　of　DC　line　protection.
