Power distribution network power failure range positioning method, system, equipment and medium

Abstract

The invention belongs to the field of electric digital data processing, and particularly relates to a power distribution network power failure range positioning method, system and device and a medium. The method comprises the following steps: establishing an information interaction and data integration platform on the basis of an on-line power grid system; constructing a power grid topological structure according to the archive relationship, and forming a geographical wiring diagram in cooperation with the equipment coordinates; obtaining a user power failure event record in real time through an intelligent electric meter HPLC module; processing user power failure event record data; associating the user power failure event with the distribution transformer according to the user relationship, and analyzing the power failure range of the distribution transformer; and calling label adding and coloring API services, and carrying out positioning, power failure label labeling and highlight display on the distribution transformer and the distribution line in the geographical wiring diagram. Based on the HPLC technology, the granularity of power failure range analysis is reduced to be below a transformer area, the accuracy of power failure range analysis of the power distribution network is remarkably improved, intelligent analysis of the power failure range is achieved, and second-level identification of a single power failure event can be achieved.

Description

technical field [0001] The invention belongs to the field of electrical digital data processing, and in particular relates to a method, system, equipment and medium for locating a power outage range of a distribution network. Background technique [0002] With the continuous maturity of distribution network technology and the continuous increase in the reliability requirements of power supply services, the rapid detection and repair of power failures in distribution network have become the service focus and important research direction of power supply enterprises. [0003] At present, in the process of power supply service management, power grid enterprises mainly rely on the OMS power outage information management system to manage the business flow of planned outages and fault outages, and mainly rely on SCADA data acquisition and monitoring control systems and distribution automation systems to realize the operation of distribution networks. For real-time perception of dat...

AI Technical Summary

Problems solved by technology

[0004] The power supply service, fault perception and equipment repair work of the distribution network have the following shortcomings: 1. The granularity of perception is not fine enough

The current power outage and fault perception of distribution network is based on SCADA and distribution automation system. Its perception granularity is at the level of 10 kV distribution switch. It is difficult to accurately and effectively perceive power outages in the station area and users below the station area. 2. Lack of active perception ability

For power outages and faults at the customer level, passive means such as telephone repairs and online repairs are still used to obtain information, and it is difficult to actively perceive; 3. Lack of accurate and intelligent analysis methods

For distribution network outages that can be sensed by existing methods, it is mainly based on the operation information of the power grid, including voltage, current, and switch displacement. The method of power outage analysis at the distribution line level in the electrical automation system is used to judge the scope of power outages, and based on the above judgments to carry out equipment inspections and emergency repairs, it cannot be refined to the station area and users, and its intelligence is insufficient. Guidance for emergency repairs The value is limited; 4. The scope of analysis is mainly based on the topological map of the power grid, lacking support information based on the actual geographical location, and has limited guiding value for emergency repair work
