Method and device for detecting fault type of power transmission line

The embodiment of the invention discloses a power transmission line fault type detection method and device. The detection method comprises the following steps of acquiring a historical fault waveform of a power transmission line; determining a historical fault type corresponding to the historical fault waveform according to a stored corresponding relationship between the fault waveform and the fault type; based on the historical fault waveform and the historical fault type, training the established convolutional neural network model to obtain a fault type detection model; and inputting the to-be-detected fault waveform into the fault type detection model, detecting the to-be-detected fault waveform through the fault type detection model, and determining a fault type. According to the power transmission line fault type detection method, efficiency and reliability of power transmission line fault type detection can be improved. 本发明实施例公开了一种输电线路故障类型的检测方法及装置，该检测方法包括：获取输电线路的历史故障波形；根据已存储的故障波形和故障类型的对应关系，确定历史故障波形对应的历史
