Abstract

The invention discloses a high-resistance grounding fault detection method, device and apparatus, and a storage medium. The method comprises the steps of obtaining to-be-analyzed high-resistance grounding data in a power distribution network; inputting the high-resistance grounding data to a preset fault detection model, and obtaining a fault detection mark corresponding to the high-resistance grounding data, wherein the fault detection model is obtained after an initial fault detection model is trained through a high-resistance grounding training sample; and obtaining a fault detection result corresponding to the high-resistance grounding data according to the fault detection mark and a corresponding relationship between the fault detection mark and the fault detection result. The technical problem that an existing high-resistance grounding fault detection method in a power distribution network is low in accuracy is solved.

Description

technical field [0001] The present application relates to the technical field of distribution network fault detection, in particular to a detection method, device, equipment and storage medium for a high-impedance ground fault. Background technique [0002] Modern society has higher and higher requirements for power quality, and the world is trying to reduce the power outage time and operating costs of distribution networks as much as possible. The detection of distribution network faults is a key link, which has been extensively studied in the world in recent decades. [0003] High-resistance ground faults are the key issues in distribution network faults. Because high-resistance ground faults are usually accompanied by arcs, they are likely to cause fires or personal accidents. In distribution network faults, high-resistance ground faults are one of the main causes of death. Therefore, it is of great significance to detect it quickly and accurately. High-resistance groun...
