Abstract

The invention relates to a public transformer station area line loss rate abnormity reason detection method and system. The method comprises steps that basic source data of a public transformer station area with line loss rate abnormity is acquired from a distribution network production system, an automatic metering system and a marketing system; one or more of the following items is analyzed for the public transformer station area with line loss rate abnormity according to the basic source data, including metering monitoring abnormity analysis, load rate analysis, power factor analysis, user CT saturation analysis, three-phase imbalance analysis and electricity stealing reason analysis; abnormity reasons of the public transformer station area with line loss rate abnormity are displayed on a display interface according to an analysis result. The method is advantaged in that through collecting data sources of the distribution network production system, the automatic metering system and the marketing system, the line loss rate abnormity reasons are analyzed and positioned through multiple analysis methods, the method is objective and real, line loss management personnel is efficiently facilitated to carry out more accurate abnormity determination, and thereby a line loss management lean level 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 the cause of abnormal line loss rate in a utility substation area. 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 ...
