Through testing, the method can quickly realize the transient waveform identification of the power transmission line, the identification accuracy reaches 92.67%, and the method can replace human experts to carry out the work in the aspect.

Description

Technical field [0001] The present invention relates to the field of power system fault identification, and more particularly to artificial intelligence fault identification systems and methods based on transient waveforms of transmission lines. Background technique [0002] The geographical conditions of the transmission line are complex and diverse, and there is a trip accident in terms of lightning, filthy, animal and plant, wind, and ice-free, and other natural factors. The route trip has a great impact on system security, equipment security, and power supply reliability. my country's power grid operation procedures require the failure position and fault type in the shortest time after trip. Therefore, fast, accurate, reliable troubleshooting and positioning techniques are particularly important for transmission line safe operation. [0003] At present, my country's power transmission line is installed with a distributed fault line wave detection device, which can measure tra...
