Remote diagnosis method based on voltage and current metering anomalies

Abstract

The invention discloses a remote diagnosis method based on voltage and current metering anomalies and relates to a metering anomaly remote diagnosis method. At present, for voltage and current metering anomaly handling, dispatching usually is directly initiated under the situation that anomaly reason analysis is not performed, and waste of resources is caused. The method comprises the steps of preliminary diagnosis and remote master station analysis, wherein during remote master station analysis, a master station archive and load data are viewed; according to generated abnormal equipment workorders, abnormal equipment data reported lately is analyzed; and when misreport, a sporadic error and an archive data error are determined, non-processing is allowed, the data waits to be archived instead, and other failure abnormal work orders try to be remotely processed. According to the technical scheme, preliminary diagnosis is performed firstly, then remote preprocessing is performed, the anomalies capable of being subjected to remote operation are directly handled, subsequent site dispatching is reduced, and manpower cost is lowered; and the diagnosis result is used for subsequent anomaly handling, the pertinence of anomaly handling is enhanced, the efficiency of handling site anomaly faults is improved, and waste of resources is lowered.

Description

technical field [0001] The invention relates to a method for remote diagnosis of measurement abnormality, in particular to a method for remote diagnosis of measurement abnormality based on voltage and current. Background technique [0002] With the increase in the construction scale and coverage of the collection system year by year, its application field has gradually expanded and its application effect has been significantly improved. The closed-loop management function of collection operation and maintenance is used as a module of the main station system for electricity information collection. By establishing a closed-loop business process of collection operation and maintenance and On-site operations are standardized and standardized to realize real-time operation and operation and maintenance monitoring of important information such as user load, electricity, voltage, and current, and provide basic data for other business systems in a timely and accurate manner. The ele...

Problems solved by technology

The electricity consumption information collection system in the prior art generally cannot make full use of advanced technologies such as big data, the Internet of Things, and wireless communication networks, and the system has a single function, generally only having the collection function and basic data analysis and calculation functions

The existing methods for voltage and current metering abnormalities, either do not use remote processing or remote processing is only for querying historical data, and lack effective analysis and diagnosis wizards, resulting in personnel directly initiating dispatch without analyzing the cause of the abnormality, or Directly initiate the process of replacing terminals or ammeters, resulting in a waste of resources and is not conducive to handling abnormal faults on site, affecting the efficiency of voltage and current abnormal processing
