Automatic cut-off and recovery method for intelligent substation communication system

Abstract

The invention discloses an automatic cut-off and recovery method for an intelligent substation communication system. The automatic cut-off and recovery method comprises the following steps: step 1, capturing and analyzing a message; step 2, monitoring; step 3, performing comparative analysis; step 4, automatically cutting off; step 5, automatic recovering. The method comprises the following steps:performing capture processing on an original data packet of a transformer substation, setting a configured filter after filter strategy setting compilation is completed, filtering a required data packet, cyclically calling back a function provided by a user through a scheduler, setting a cyclic capture packet, transmitting the data packet to an application program, and then analyzing an application layer message through message analysis; the system analyzing the captured data packet, and importing a configuration file detection message through an abnormality monitoring module; performing comparative analysis on the abnormal message information detected by the detection module and normal message information detected by the detection module and stored in a database. According to the method,automatic cut-off and recovery can be realized, and the monitoring effect on abnormal data is good.

Description

technical field [0001] The invention relates to the technical field of intelligent substations, in particular to a method for automatically disconnecting and restoring a communication system of an intelligent substation. Background technique [0002] Smart substation adopts advanced, reliable, integrated and environment-friendly intelligent equipment, with the basic requirements of digitalization of whole station information, networking of communication platform, and standardization of information sharing, and automatically completes basic functions such as information collection, measurement, control, protection, measurement and detection. At the same time, for substations with advanced functions such as real-time automatic control of the power grid, intelligent adjustment, online analysis and decision-making, and collaborative interaction, the communication system of the intelligent substation in the prior art cannot realize automatic cutting and recovery, and the monitorin...
