Abstract

The invention discloses a fast anomaly detection method for large-scale power transmission and transformation equipment monitoring data streams. The method includes the following steps: performing clustering and category marking on historical data by using a DBScan algorithm, and sending a marked sample to a SparkStreaming cluster to perform real-time incremental clustering; enabling a front-end processor to receive data streams sent by various terminals, pushing the data streams to a Spark Steaming (as shown in the original document) cluster for processing, and implementing real-time featureextraction and normalization processing on the Spark Steaming cluster; and then performing real-time clustering to complete the judgment of a new sample category. By adopting the method, the fast analysis of large-scale data streams of smart power grids can be realized, and the fast anomaly detection of the large-scale power transmission and transformation equipment monitoring data streams can beimplemented.

Description

technical field [0001] The invention relates to the field of large-scale power transmission and transformation equipment monitoring, in particular to a fast anomaly detection method for monitoring data streams of large-scale power transmission and transformation equipment. Background technique [0002] With the advancement of smart grid construction, multiple links in the power system are facing the challenge of rapid analysis of large-scale data flows. Especially in the online monitoring system of power transmission and transformation equipment, as the monitoring scope expands and the depth continues to strengthen, a large number of multi-source heterogeneous monitoring data collected by many measurement and sensing devices are continuously sent to the monitoring center in the form of data streams, forming Large-scale monitoring data flow, and the monitoring center needs to process these streaming data in real time and quickly. [0003] The current mode of testing data ana...
