Research on Fault Early Warning Technology of Key Operation Nodes in Power Communication Network

Abstract

In the process of power grid operation and maintenance, the current fault early warning technology has the problem of single access channel, which leads to more misjudgments. This paper designs a research on fault early warning technology of key nodes in power communication network operation. Using stratified sampling method, combined with data mining technology to detect abnormal network operation data, switching communication network access channels, developing link control procedures, using three-scale analytic hierarchy process to identify key nodes, sending information symbols and check symbols at the same time, eliminating the problem of information dispersion, setting fault early warning mode. Experimental results: the design of fault early warning technology, and the other two kinds of early warning technology, the average number of misjudgment is 8.06, 9.8, 10.06, which proves that the design of fault early warning technology has higher use value.
