Method for generating big data causal model in corresponding power grid operation environment

Abstract

The invention relates to a method for generating a big data causal model in a corresponding power grid operation environment, and belongs to the technical field of power grid automatic scheduling. Themethod comprises the following steps: 1) obtaining a correlation factor set of events occurring in the operation process of current power grid equipment; 2) screening out high-probability associationfactors of which the correlation with the event is greater than a preset value from the association factor set; 3) performing causal relationship detection on the high-probability association factorsand the events, and determining strong association factors; 4) generating a big data causal model by utilizing a Bayesian causal network and regulation big data based on the strong correlation factors; and 5) carrying out matching combination on the big data causal model and a preset experience model to generate a regulation and control business big data causal model of the current power grid equipment. By applying the method, the causal relationship between the defect event of the power grid equipment and each factor influencing the time can be intuitively reflected, so that an observer canquickly obtain the cause of the defect of the power grid equipment in an emergency situation.

Description

technical field [0001] The invention relates to a method for generating a big data causal model corresponding to a power grid operation environment, and belongs to the technical field of power grid automatic dispatching. Background technique [0002] With the continuous development of science and technology and the continuous improvement of the power system, it not only brings infinite convenience to people's life (such as lighting, etc.), but also provides more convenience in people's travel (such as electric vehicles, trains and trams, etc.). With the overall acceleration of UHV power grid construction, the rapid development of new energy and the deepening of electricity market-oriented reforms, the integrated operation of power grids has become more and more obvious. Collaboration and other needs are more urgent. [0003] In recent years, the information resources that can be obtained by the power grid dispatching control center have become more and more abundant, and t...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is that in the current power grid system, the information resources that can be obtained by the power grid dispatching control center are becoming more and more abundant, and there are more and more information sources available for the regulation and analysis of power grid equipment, and the amount of information is huge. Big data statistics itself is a method of statistical analysis, unable to test the logical causal relationship, making it difficult for observers to quickly and intuitively understand the direct cause of grid defects from a large amount of information
