Abstract

The present invention provides a method and device for diagnosing abnormal line loss based on a power curve characteristic model. The method is applied in the field of electric power technology. The method includes: obtaining the first source data from the first system; Set rules to process the first source data to obtain second source data; use the Pearson correlation coefficient algorithm to perform first line loss abnormality diagnosis and analysis on the second source data, and use clustering algorithm and decision analysis algorithm to analyze all The above-mentioned second source data is used for the second line loss abnormality diagnosis and analysis. The abnormal line loss analysis method and device based on the characteristic parameter model of the power curve provided by the present invention adopts two abnormal line loss 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,...
