Line loss abnormity location method and system

Abstract

An embodiment of the invention discloses a line loss abnormity location method. The method comprises obtaining the month line loss rate on line loss lines, recalculating the month line loss rate larger than the preset threshold on the line loss lines according to the set line loss calculation model and month line loss rate, and determining actual month line loss lines, actual line loss months and the line loss conditions of the months after comparing the recalculated month line loss rate with the preset threshold; obtaining the day line loss amount in every month on the line loss lines, calculating the day line loss amount difference between the same line loss line and the same month adjacent days according to the obtained day line loss amount, and determining actual day line loss lines, actual line loss days and line loss conditions of the line loss days after comparing the day line loss amount difference to be calculated with a preset day line loss amount mutation value. The embodiment of the invention further discloses a line loss abnormity location system. According to the method and the system, the problems of lack of automatic means for diagnosis analysis, large troubleshooting difficulties and heavy workloads of line losses in the prior art are solved.

Description

technical field [0001] The invention relates to the technical field of power system line loss analysis, in particular to a method and system for locating abnormal line loss. Background technique [0002] Line loss is an important comprehensive economic index to measure electric power enterprises. It runs through the whole process of "generation, transmission, distribution and consumption", and comprehensively reflects the level of power grid planning and design, production technology and operation management. How to use the line loss data to mine the abnormal information behind the hidden data, identify and terminate the abnormality in time. In the face of huge and complex data, it is necessary to design a simple, efficient and rigorous line loss anomaly precise location information system for unified management, analysis and application. [0003] At present, the domestic systems with line loss statistics mainly include marketing system and metering automation system, but t...
