Abstract

The invention provides a line loss abnormality diagnosis method and a device based on an electric quantity curve characteristic model. The method is applied to the technical field of electric power. The method comprises the following steps of: obtaining first source data from a first system; obtaining the first source data from the first system; processing the first source data according to a preset rule in a second system to obtain second source data. A Pearson correlation coefficient algorithm is used to perform a first line loss anomaly diagnosis analysis on the second source data, and a clustering algorithm and a decision analysis algorithm are used to perform a second line loss anomaly diagnosis analysis on the second source data. The method and device for analyzing line loss abnormality based on characteristic parameter model of electric quantity curve provided by the invention adopt twice line loss abnormality analysis, the calculation speed is fast, the data acquisition is convenient, and the reliability of the analysis result is high.

Description

technical field [0001] The invention belongs to the field of electric power technology, and more specifically relates to a method and device for diagnosing abnormal line loss based on a power curve characteristic model. Background technique [0002] Power grid power loss rate, referred to as line loss for short, is an important comprehensive technical and economic index for electric power enterprises. It reflects the planning and design, production technology and operation management level of a power network, and has long been valued by power companies at all levels. With the development of the economy and the deepening of power marketization, in order to reduce the operating cost of the power grid, higher requirements are put forward for the work of energy saving and loss reduction of the power grid. When the acquisition device fails, the acquisition data transmission fails, the line transformer relationship error, the system file error, the concentrator measurement error,...
