Power distribution automation terminal fault diagnosis method and device, equipment and storage medium

Abstract

The invention discloses a power distribution automation terminal fault diagnosis method and device, equipment and a storage medium. The method comprises the following steps: acquiring an alarm signal of a power distribution automation terminal acquired by a collector, arranging the collector in a field of the power distribution automation terminal, inputting the alarm signal into a preset first classification model for processing to obtain a first fault diagnosis result of whether the alarm signal has a fault, and if the first fault diagnosis result is that the fault exists, classifying the alarm signals by adopting a clustering algorithm to obtain a second fault diagnosis result of the fault category of the alarm signals. By performing text classification on the alarm signals, the fault diagnosis of the power system can be accurately and efficiently realized, multiple different faults occurring at the same time can be accurately diagnosed, the power distribution operation and maintenance working efficiency is improved, and data support is provided for subsequent operation and maintenance.

Description

technical field [0001] Embodiments of the present invention relate to power fault analysis technology, and in particular to a method, device, equipment and storage medium for fault diagnosis of a power distribution automation terminal. Background technique [0002] In terms of ensuring the safe operation of the distribution network and improving the reliability of power supply, distribution automation terminals are playing an increasingly important role. The fault message of the distribution automation terminal is of great significance to the fault trip analysis of the distribution line, and the fault area can be remotely and conveniently identified through the "three remote" information. [0003] However, since the distribution network generally adopts the wireless public network communication method, the frequency of sending messages is limited, and the fault instantaneous current and voltage values ​​cannot be sent to the master station, and the fault action value can onl...

[0003] However, since the distribution network generally adopts the wireless public network communication method, the frequency of sending messages is limited, and the fault instantaneous current and voltage values ​​cannot be sent to the master station, and the fault action value can only be viewed at the distribution automation terminal.

[0004] At present, the common method is to take pictures to record. However, the safety risk of high-altitude operation is high, it takes a long time, and the photo collection is easy to record incompletely. Multiple photos are also not good for fault analysis, which has formed a serious restrictive factor for rapid fault analysis.
