Dynamic updating method of safety check standard library based on data mining

Abstract

The invention discloses a dynamic updating method of a safety check standard library based on data mining. The method comprises the following steps: extracting N types of characteristics from a safety check result library, synthesizing the N types of characteristics and obtaining N-dimensional vectors; performing normalization processing on the N-dimensional vectors to obtain a data set; using a canopy algorithm to aggregate the data set to obtain a first cluster, and according to a K value of the first cluster; according to the K value, using a K-Means algorithm to cluster the data set until a central point converges or reaches a preset requirement, and obtaining a plurality of clusters; and determining key elements in every cluster according to a preset vector similarity threshold, extracting key attributes which lead to system operation safety hidden dangers according to the key elements, when the quantity of key attributes of a new check item in the safety check result library is greater than a preset key attribute quantity threshold, adding the new check item to the safety check standard library. The dynamic updating method of the safety check standard library based on the data mining provided by the invention has the following advantages: the update time is shortened, and whether or not the new check item is added to the safety check standard library is judged automatically.

Description

technical field [0001] The invention relates to the field of electric power system safety inspection automation, in particular to a method for dynamically updating a safety inspection standard library based on data mining. Background technique [0002] With the rapid development of social economy, the construction of power grid has also entered a period of rapid development, the scale of power grid has reached a high level, and the structure of power grid has become increasingly complex. The number of power equipment is growing rapidly, and the amount of data information generated by equipment running in the power system is increasing sharply. In this case, ensuring the safe and stable operation of the power grid is the top priority of the power grid, and safety inspection is one of the important links to ensure the safe operation of the power grid. [0003] The traditional safety inspection is that the relevant staff conduct regular or irregular inspections or spot checks ...

Problems solved by technology

[0003] The traditional safety inspection is that the relevant staff conduct regular or irregular inspections or spot checks on each inspection item item by item according to the contents of the safety inspection standard library. However, with the increase of the power grid scale, the traditional safety inspection standard library has been unable to keep up with the power grid. The update speed and structure complexity of system operation safety production inspection items will inevitably lead to omissions, or long-term non-updating of inspection items will result in low work efficiency or duplication of labor
