Abstract

The invention discloses a line loss query method and system for a power distribution network. The system comprises a data acquisition module which is used for acquiring electric quantity data of eachzone area of the power distribution network; a construction module used for constructing a data analysis model, wherein the data analysis model is obtained by training a plurality of groups of data, and each group of data comprises an electric quantity transmission initial value and a final transformer area transmission value; the analysis module is used for analyzing the acquired electric quantity data of each transformer area according to the data analysis model so as to determine the line loss of each transformer area; and the determination module is used for determining whether the transformer area is abnormal or not according to the line loss of each transformer area. According to the method and the device, the technical problems of high line loss treatment difficulty and low efficiency due to the fact that on-site checking is needed when the line loss of the power grid is inquired in the prior art are solved.

Description

technical field [0001] The invention relates to the technical field of distribution network, in particular to a method and system for querying line loss of a distribution network. Background technique [0002] The line loss is the sum of the power loss generated in the transmission, transformation, distribution and power consumption during the transmission of electric energy from the grid to the user. The line loss rate is the ratio of the power loss to the total power supply in a certain period of time. , is an important indicator to measure the technical economy of power grid enterprises. The current power grid line loss is mainly in each station area, but the current line loss control of the station area is mainly through the analysis of each station area on the intranet desktop computer. At the same time, abnormalities need to be screened out The details of the station area. The screened abnormal stations need to analyze the power supply relationship, metering device, c...
