A power grid accident correlation reason backtracking method based on data mining and visualization

Abstract

The invention relates to a power grid accident correlation reason backtracking method based on data mining and visualization, and belongs to the field of intelligent retrieval. The method comprises the following steps: S1, data mining; S2, accident event tracing retrieval; S3, displaying a tracing process in combination with a lexicon association rule; When the electric power system is in an operation state, if the system has a problem, the action information of the protection device can transmit the related information of the fault to the dispatching center; Fault information is imported intoan intelligent analysis system fault data mining algorithm is established, fault data can be analyzed, fault characteristics can be extracted, historical accident event data can be collected, mesh topology display can be carried out according to other operation information associated with the elements, and scheduling personnel can be assisted to investigate accident events, so that the system operation personnel can quickly judge and process power system faults.

Description

technical field [0001] The invention belongs to the field of intelligent retrieval and relates to a method for backtracking related causes of power grid accidents based on data mining and visualization. Background technique [0002] At present, due to the lack of support tools with closed-loop control functions such as operation instruction assistance and technical evaluation of operation results in the process of power grid dispatching operation, it is impossible to prevent the occurrence of failure problems in advance, and when equipment operation problems occur, resulting in equipment failure safety accidents, It is impossible to intuitively trace the causes of safety accidents, and it is impossible to conduct technical evaluation on the operation results of the next command issued by the same equipment to provide improvement measures. In addition, in the process of operation, there is no quantitative assessment basis for the operation efficiency and completion quality of...

Problems solved by technology

[0002] At present, due to the lack of support tools with closed-loop control functions such as operation instruction assistance and technical evaluation of operation results in the current power grid dispatching operation process, it is impossible to prevent the occurrence of failure problems in advance, and when equipment operation problems occur, resulting in equipment failure safety accidents, It is impossible to intuitively trace the cause of safety accidents, and it is impossible to conduct technical evaluation on the operation results of the next command issued by the same equipment to provide improvement measures

In addition, in the process of operation, there is no quantitative assessment basis for the operation efficiency and completion quality of the various disciplines of the system, and the operation efficiency of the power grid control and system operators cannot meet the requirements of the rapid development of the power grid
