Abstract

The invention discloses a local node mining method based on distributed data stream processing. The local node mining method comprises the following steps: S1, selecting a data sequence; S2, establishing a big data stream classification model; S3, a local node mining method; and S4, a center node mining method based on the unbalanced data stream. According to the local node mining method, the problem of local node mining in power grid equipment online monitoring data stream distributed processing is solved based on the data stream cleaning method for the power grid equipment from the perspective of large data stream distributed processing.

Description

technical field [0001] The invention relates to data processing of power grid equipment, in particular to a local node mining method based on distributed data flow processing. Background technique [0002] At present, as the entire power grid is moving towards the direction of intelligence, informatization and network, various sensors and various automatic monitoring equipment are widely used in the power grid, which makes the automatic monitoring system in the power grid form a huge amount of monitoring in real time. data. According to statistics from relevant departments, as of 2013, the State Grid has installed a total of 182 million smart meters and completed the collection of electricity consumption data for 191 million users, making the automation system for electricity consumption data collection the largest in the world for electric energy. The metering automation system requires real-time acquisition of grid equipment monitoring data, so that the amount of data col...
