Power failure monitoring method for feeder and important customers based on metering automation system

Abstract

The invention provides a power outage monitoring method for feeder and important customers based on a metering automation system, which comprises the following steps of: obtaining load data of a transformer of the metering automation system and event information reported by a metering automation equipment terminal in real time; classifying the transformer as the transformer with outage alarm or incoming call alarm, and the transformer without outage alarm and incoming call alarm according to the outage alarm and incoming call alarm in the event information; identifying a power outage time of atransformer with a power outage alarm or an incoming call alarm, and identifying a power outage time of a transformer without a power outage alarm or an incoming call alarm; determining whether the blackout lines and important customers are blackout or not according to the transformer and its blackout time,. The invention realizes the real-time monitoring of the 10kv feeder outage condition by the metering system, greatly improves the monitoring efficiency and accuracy of the 10kv feeder outage condition, and solves the technical problem that the prior art adopts the manual processing mode with low efficiency and poor accuracy, and can not provide the technical means of real-time, reliability and high accuracy.

Description

Technical field [0001] The invention relates to the technical field of metering automation, in particular to a method for monitoring power outages of important customers and feeders based on a metering automation system. Background technique [0002] The metering automation system realizes the collection of raw data related to power system metering equipment, covering all substations, power plants, special transformers, public transformers and low-voltage users in the area. The provincial centralized metering system integrates the metering systems and electrical energy data of the original cities The related functions of the platform realize the provincial management of metering business and data, and realize data interaction and information integration with external systems such as the network-level electric energy data platform system and the provincial marketing management information system, and provide comprehensive metering business applications and data analysis , To provi...

AI Technical Summary

Problems solved by technology

[0004] At present, the coverage rate of distribution network automation terminals is low, and it is impossible to achieve full coverage of 10kv feeders and important customers. It is impossible to monitor the operation and power failure status of 10kv feeders in real time, and there are blind spots in the monitoring range. It has a shortpart

[0005] In view of the fact that the metering automation system has achieved 100% full coverage of the public substation terminal, the terminal online rate and the complete data collection rate are relatively high. However, for 10kv feeders and important customer power outages, it is still a blind area of ​​distribution network line scheduling. The existing The technology uses manual processing with low efficiency and poor accuracy, and cannot provide real-time, reliable, and accurate technical means
