Problems solved by technology

[0012] 1) When denoising, only the history event table is used without combining other relevant information, resulting in long denoising time
[0013] 2) The decision tree algorithm was not improved during denoising, resulting in a decrease in classification accuracy
[0014] 3) When using the rough set algorithm for rule reasoning, the alarm type is only set to the

Embodiment Construction

[0053] The technical content of the present invention will be further described in detail below with reference to the drawings and specific embodiments.

[0054] Such as figure 1 As shown, the intelligent alarm analysis method for power grid dispatch provided by the present invention includes the following steps: extracting the alarm information of the power grid, preprocessing the alarm information of the power grid, and collecting statistics on the daily and monthly reporting times of the alarm information and noise data Relationship, set an appropriate threshold according to the operation of the power grid and the requirements of alarm accuracy. When the number of daily and monthly reports of alarm information exceeds the set threshold, the alarm information is obviously noise data, and the obvious Noise data: Associate the alarm information with the remote measurement value to remove the wrong alarm information; then use the decision tree algorithm with Bayesian nodes to class...

Abstract

The invention discloses a power-network-dispatching-oriented intelligent warning analysis method. The method comprises the following steps that warning information of a power network is extracted and is preprocessed; denoising is carried out on the preprocessed warning information, and a denoising classification rule is obtained; the denoised warning information is subjected to induction and dupliction removal, warning combinations are generated, and the warning type to which each warning combination belongs is judged; each warning combination and the corresponding warning type are subjected to association rule mining, and a power network warning inference rule is obtained. After the intelligent warning analysis method is utilized, the filtering rate of noise data in the warning information and the comprehensiveness of the warning types are improved.

Description

Technical field [0001] The invention relates to an alarm analysis method, in particular to an intelligent alarm analysis method oriented to power grid dispatching, and belongs to the technical field of power system dispatching. Background technique [0002] With the continuous expansion of the scale of the power grid, the alarm information generated is also increasing, and thousands or even tens of thousands of alarm information flood into the control center every day. The abnormality of the measuring equipment during operation and the necessary equipment maintenance will generate noise data, resulting in insufficient accuracy of the alarm information. At the same time, the current alarm information is directly presented to dispatchers at an extremely fast speed, and no associated grid reasoning rules have been formed, which makes dispatchers unable to quickly determine the type of alarm. [0003] In order to ensure the accuracy of alarm information and quickly determine the type ...
