Research on Intelligent Judgment Technology of Monitoring Alarm Based on Power Grid Topology Division

In order to effectively solve the problems of discrete and complex alarm information and single display means in power dispatching automation system, this paper proposes an intelligent research and judgment technology of power grid monitoring alarm based on power grid topology analysis. According to the topology search of adjacent devices and the topology search of power supply path, this method divides the devices with electrical relationship, integrates the alarm data regularly according to the electrical associated path of the equipment, and forms different alarm data sets; through the alarm data set, keyword extraction and knowledge evaluation network are established to study and judge the alarm information. This method can assist the dispatcher to locate the key equipment of operation monitoring in time. It can quickly and effectively screen and extract important information from the massive operation data, and improve the speed and reliability of power grid monitoring alarm.
