Abstract

The invention relates to a method and system for detecting a line loss rate anomaly reason of a 10kV line. The method comprises the steps of acquiring basic source data of a 10kV line with the line loss rate being abnormal from a distribution network production system, a measurement automation system and a marketing system; performing any one or more items of measurement monitoring anomaly analysis, load rate analysis, power factor analysis, user CT saturation analysis, line diameter analysis and electricity stealing reason analysis on the 10kV line with the line loss rate being abnormal according to the basic source data; and displaying an anomaly reason of the 10kV line with the line loss rate being abnormal on a display interface according to an analysis result. According to the invention, analysis and positioning are performed on the anomaly reason of the 10kV line with the line loss rate being abnormal by combining various analysis methods through data source collection for the marketing management system, the measurement automation system and the production system, so that the line loss management personnel can be more efficiently assisted to perform more accurate anomaly judgment, and the lean level of line loss management is improved.

Description

technical field [0001] The invention relates to the field of power grid line loss analysis, in particular to a method and system for detecting abnormal causes of line loss rate of 10kV lines. Background technique [0002] Line loss is a general term for the comprehensive power loss of the power grid, and it is the total power loss that occurs during the power transmission process of the power grid operating enterprises. The line loss index is the core index to measure the planning and design, production operation, management level and comprehensive strength of the power grid enterprise, and it is the "international language" for dialogue with the advanced level. The level of line loss directly affects the economic benefits of enterprises, and has become an important breakthrough to improve operating benefits and enhance core competitiveness. At present, the daily line loss management of power supply enterprises only relies on on-site inspections, personal experience and ski...
