Dynamic Adjustment Method of Equipment Performance Index Threshold in Electric Power Monitoring System

Abstract

The present invention provides a method for dynamically adjusting the performance index threshold of the power monitoring system equipment, which includes setting the trigger condition for calculating the dynamic threshold value of the index in the network security management platform. Index data, clustering based on the weighted cosine similarity, comparing the clustering results with the previous clustering results, if the clustering results no longer change, then output the clustering results, otherwise re-clustering based on the square mean Class center, re-clustering. Finally, according to the output clustering results, the performance index threshold of the power monitoring system is calculated. The present invention calculates the alarm thresholds of each indicator in each device in the power monitoring system through the k-means algorithm, and at the same time periodically adjusts the alarm thresholds to achieve the purpose of dynamically adjusting the indicator alarm thresholds and reduce the generation of alarm false alarms.

Description

technical field [0001] The invention relates to a method for dynamically adjusting the performance index threshold of an electric power monitoring system, belonging to the technical field of electric power monitoring. Background technique [0002] At present, the safety thresholds of various performance indicators such as hosts, network devices, security devices, and databases in the power monitoring system are manually configured in the network security management platform. The operation and maintenance personnel in the power monitoring system are good and bad, and the thresholds configured based on their own experience cannot well reflect the situation of the equipment in the area. This is not only prone to false alarms, but also the risk of false alarms. At the same time, there is no relevant scientific basis , the failures that occur cannot be eliminated in time, seriously affecting work efficiency and affecting the stable operation of the power monitoring system.

Problems solved by technology

The operation and maintenance personnel in the power monitoring system are good and bad, and the thresholds configured based on their own experience cannot reflect the situation of the equipment in the area. This is not only prone to false alarms, but also the risk of false alarms. At the same time, there is no relevant scientific basis , the failure can not be eliminated in time, which will seriously affect the work efficiency and affect the stable operation of the power monitoring system

Especially when the power monitoring system is in an emergency situation, a large number of alarms make it impossible for managers to judge the fault in a timely and accurate manner, which will lead to missing the best time to deal with the accident and cause the accident to expand.
