Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings.

[0032] The grid resource fault diagnosis method based on association rules of the present invention comprehensively collects relevant data of power equipment, establishes a multidimensional data model and a fault fact table, provides a data basis for data mining, uses cluster analysis to conduct preliminary analysis on data, and synthesizes various types of data Carry out data association analysis, compare and judge, form multi-intelligence criterion synthesis, and accurately judge faults, such as figure 1 shown, including the following steps,

[0033] Step (A), extracting fault data, converting the fault data, and loading it into the data warehouse, establishing a multidimensional data model and fault fact table, and extracting fault data is to extract historical fault data from the data warehouse, mainly from PMS, SCADA / EMS, MIS, DBMS, PUMs, GIS and other systems; ...

Abstract

The invention discloses a power grid resource fault diagnosis method based on association rules. The method comprises the following steps: A, drawing off fault data, converting the fault data, loading the fault data to a data warehouse, and establishing a multidimensional data model and a fault fact table; B, performing cluster analysis on the fault data; C, performing association rule analysis on the fault data; and D, abstracting actual fault events as nodes, if it is compared that a high-credibility fault power grid device accords with a calculated aggregation degree, obtaining a diagnosis result, and giving assistance advice for processing of power grid faults. According to the invention, correlation data of power equipment can be comprehensively acquired, the multidimensional data model and the fault fact table can be established, a data base is provided for data mining, data is preliminarily analyzed by use of the cluster analysis, data association analysis is performed by integrating various data, comparative determining is carried out, integration of multiple intelligent criteria is formed, the faults are accurately determined, and the application prospect is good.

Description

technical field [0001] The invention relates to the technical field of grid fault analysis, in particular to a grid resource fault diagnosis method based on association rules. Background technique [0002] With the continuous expansion of the power grid scale, there will be a large amount of fault information for power equipment when a fault occurs. When the dispatch center receives this information, the dispatcher will generally quickly analyze the fault characteristics, judge the faulty equipment and restore power supply as soon as possible. In the actual diagnosis of power grid faults, dispatchers are faced with the problem of how to find out the correlation between the cascading faults and the probability of causing other faults from the massive historical fault data. [0003] Our country's research on fault diagnosis technology can be divided into two stages. The first stage is the initial stage. It took about 10 years from 1979 to 1990. The characteristic of this stage...
