Line fault single-end traveling wave identification and wave head calibration method based on oscillogram sensitive angle detection

The invention relates to a line fault single-end traveling wave identification and wave head calibration method based on oscillogram sensitive angle detection, and belongs to the technical field of power transmission line fault positioning. Firstly, a time domain waveform is imaged, the most sensitive angle of wave head sudden change is detected by using Radon transformation variable angle projection under a digital image visual angle, and detection effectiveness checking is performed by using non-axisymmetric characteristics of two sides of the most sensitive angle of the wave head, so that a wave head group containing a plurality of wave heads can be effectively detected, and the method has self-checking capability and can be suitable for various bus outgoing line types. The wave head calibration method provided by the invention has strong robustness, and the detection result is not influenced by fault conditions, signal conditioning links and algorithm parameters. 本发明涉及一种基于波形图灵敏角检测的线路故障单端行波识别与波头标定方法，属于输电线路
