Power distribution network fault positioning research and judgment method and system, computer equipment and storage medium

Abstract

The invention relates to a power distribution network fault positioning research and judgment method and a system, computer equipment and a storage medium. The method comprises the steps of collecting output information of different associated systems, and performing data fusion processing on the output information to obtain fault research and judgment data; and based on the main and distribution network topology structure, performing hierarchical fault research and judgment on the fault research and judgment data, generating a corresponding fault research and judgment result, determining a fault type and a fault area of the power distribution network according to the fault research and judgment result, and generating corresponding alarm information. According to the method, outputs of a plurality of different associated systems are collected for fusion and integration, so that more comprehensive fault research and judgment data can be obtained, and a more accurate fault research and judgment result is obtained when hierarchical and hierarchical fault research and judgment are performed according to the comprehensive fault research and judgment data; therefore, rapid fault location positioning and rapid first-aid repair by matching first-aid repair measures are realized, the power distribution network fault repair efficiency is improved, and rapid power distribution network fault recovery is achieved.

Description

technical field [0001] The present application relates to the technical field of electric power engineering, in particular to a method, system, computer equipment and storage medium for fault location and judgment of distribution network. Background technique [0002] With the development of power engineering technology, as well as the improvement of economic and living standards, people's demand for the reliability and quality of power supply of distribution network is also increasing. In order to ensure good power supply reliability and power supply quality, it is necessary to pay attention to the operation status of the power system of the distribution network, carry out fault diagnosis on the operation process of the distribution network, find out the fault in time, and then realize the recovery after the fault of the distribution network. Quick recovery. [0003] Among them, distribution network fault diagnosis is a device that identifies the location, type and misoper...

Problems solved by technology

[0004] However, due to the fact that most of the traditional diagnosis methods are aimed at the transmission network and focus on the use of local information of a single diagnostic object, and considering the complex and changeable structure of the distribution network, the many branches, and the degree of automation of the distribution network, there are a large number of uncertain factors, which affect Integrity of information, so that fault diagnosis cannot be performed based on comprehensive distribution network information

Therefore, when multiple faults occur, there will be a large number of faulty components and non-faulty components in the power-off area, and the switch protection will refuse to operate or malfunction, which is easy to interfere with fault research and judgment, and it is impossible to accurately know the faults in the distribution network type, and it is impossible to accurately analyze the location of different faults, resulting in low efficiency of distribution network fault repair, and cannot guarantee rapid recovery after distribution network faults
