Traveling wave distance measurement method and system based on variable scale waveform dynamic analysis

The invention provides a traveling wave fault location method and system based on variable scale waveform dynamic analysis. The method comprises the following steps: screening candidate data segments containing fault points according to a pre-trained anomaly detection neural network; for the candidate data segment containing the fault point, roughly positioning a section where the fault point is located based on a waveform form movement algorithm; and based on the determined section where the fault point is located, accurately positioning the fault point by using a morphological analysis algorithm. According to the invention, each data segment near the fault point can be screened out through an algorithm, the range of the fault point can be limited according to waveform form dynamic analysis, various complex waveforms can be analyzed to the maximum extent by introducing the traveling wave fault location method based on variable scale waveform dynamic analysis, and the fault location precision can be improved.
