Abstract

The invention discloses a user fault positioning method and a user fault positioning device. The User fault positioning method comprises the steps of: acquiring a power load data model and a power grid data model, wherein the power load data model is a model established according to power grid information data of target users, and the power grid data model is a model established according to powerequipment operation data relevant to each target user, and an association relationship exists between the power grid data model and the power load data model; detecting whether power equipment in thepower grid data model fails; and determining a suspected fault user according to the association relationship exists between the power grid data model and the power load data model when detecting that one or multiple sets of power equipment in the power grid data model fails, wherein the suspected fault user is a user corresponding to the failed power equipment. The user fault positioning methodand the user fault positioning device solve the technical problem of low efficiency of positioning fault users when dealing with power system failures in the related technologies.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a user fault location method and device. Background technique [0002] In related technologies, when determining the scope of influence of equipment failure in the power system, the scope of influence of the failed power equipment is generally manually analyzed, and the analysis efficiency is low and the analysis time is relatively long. In the current power system, it generally includes plants, stations and operating lines. Among them, plants and stations generally include switches, switches, busbars, transformers, generators, capacitors, load lines and other equipment. The relationship between plants and stations is connected by power operating lines. To form a network topology, the power equipment is connected with switches and switches to form a plant station topology. When a fault occurs on the operating line in the power system, it is necessary to determine the loc...
