Intelligent distribution network fault positioning and early warning system based on multi-source sensing cooperation

Abstract

The invention discloses an intelligent distribution network fault positioning and early warning system based on multi-source sensing cooperation, and relates to the technical field of fault positioning and early warning. The system comprises an edge sensing node module, a self-organizing networking module, a data sharing module, a collaborative research and judgment module and a decision output module. The edge sensing node module collects a distribution network multi-source signal and triggers a distributed collaborative decision when the distribution network multi-source signal is abnormal; the self-organizing networking module completes node scanning and multi-dimensional core node screening, and builds and monitors a temporary collaborative consensus group; the data sharing module realizes intra-group feature data sharing; the collaborative research and judgment module forms a research and judgment result, and triggers secondary acquisition verification when the research and judgment result is not consensus; and the decision output module pushes early warning information, and generates and uploads a fault positioning result and a disposal scheme. According to the invention, edge-side autonomous collaborative decision is realized, main station dependence is broken through, fault response time delay is shortened, misjudgment and missed judgment rates are reduced, and distribution network power supply reliability is improved.
