Embodiment Construction

[0021] Such as figure 1 As shown, a method for data mining and analysis of abnormal line loss causes, including steps:

[0022] S100: Establish a line loss cause analysis specification, wherein the line loss cause analysis specification includes a line loss abnormality cause definition, a line loss abnormality analysis guideline, and a line loss abnormality handling guideline.

[0023] The data required for the establishment of line loss cause analysis specifications can be obtained from historical experience data or expert database data. Specifically, step S100 is specifically: based on the actual line loss analysis workflow and business connotation, sort out the cause map of the line loss abnormality. Combined with the business terminology, it gives the definition of abnormal line loss causes, standardizes the definition and application rules of abnormal line loss reasons, and provides analysis guidelines and handling guidelines for various abnormal line loss causes.

Abstract

The invention provides a method and a system for line loss abnormal reason data mining and analysis. The method includes: establishing a line loss reason analysis standard, obtaining line loss resource information, conducting a line loss resource information analysis according to the line loss reason analysis standard, building a line loss basic information model, obtaining power grid business data, performing line loss abnormal reason data mining and relative information characteristic analysis according to the power grid business data, the line loss resource information, and the line loss basic information model, finding a large-probability reason for line loss anomaly, according to the idea of EMS and DMS state estimation, performing metering bad data identification, thereby correcting the large-probability reason for line loss anomaly, and obtaining the large-probability reason for line loss anomaly after correction. In the whole process, mining and analysis of the power grid business data and the practical condition of power grid line loss resources are performed, and accurate analysis of the line loss abnormal reason is realized.

Description

technical field [0001] The invention relates to the technical field of power grids, in particular to a method and system for data mining and analysis of abnormal line loss causes. Background technique [0002] Line loss refers to the energy loss dissipated in the form of heat energy, that is, the active power consumed by resistance and conductance. The causes of line loss during the transmission of electric energy include resistance, magnetic field and management. [0003] In the past, although there are many theories in the research and results of line loss management, these measures and studies are often researched and analyzed from the theoretical knowledge of line loss, and fail to fully consider the line loss management of power supply enterprises in specific regions. Analyze the situation. [0004] If the line loss management of power supply enterprises in specific regions is not analyzed, there will be large errors in the research results of line loss management. ...
