Abstract: In view of the problems such as low fault location accuracy of existing cable-overhead-hybrid transmission lines and difficulty in identifying the traveling wave head, this paper presents a newfashioned fault location technology for cable-overhead-hybrid transmission lines. Accurate calibration of the traveling wave head is achieved by improving the HOVMD-TKEO method. And based on this, the fault accurate location of overhead-cable hybrid line is realized by wave velocity normalization method. Finally, the feasibility and accuracy of this method is verified by PSCAD/EMTDC simulation analysis of 110kV cable-overhead-hybrid transmission lines.
