Abstract

The invention discloses an online and on-off detection control method for intelligent substation switching equipment, comprising the following steps of: analyzing an intelligent substation SCD file, and obtaining an IED device and APPID correspondence table; identifying, by a service sensing unit, a GOOSE message and a SV message generated by the IED device, and establishing a switch port and APPID storage table; comparing and merging the two tables to complete a connection relationship binding between the an information exchange device port and the IED device so as to the sense the online state of the IED device at a specific port; setting a time period, regularly generating a switch port and IED device correspondence table, comparing the two switch port and IED device correspondence tables so as to determine an offline IED device. The technical solution in the present invention solves the problem that an existing Layer-2 switch cannot detect and sense the online and on-off state of the IED device connected to each service port of the switch, and is unable to control the offline IED device such that the debugging and operation and maintenance difficulty of the intelligent substation is increased.

Description

technical field [0001] The invention relates to the technical field of electric power system automation, in particular to a detection and control method for switching equipment in an intelligent substation on-line and switching on and off. Background technique [0002] In today's network-centered smart substation, the switch is an important communication hub device; the operating status of the switch is crucial to the security, reliability and effectiveness of data and information in the smart substation, so it is necessary to Monitor the operating status of the switch. The operating status of the switch includes status information such as port online / offline status, port bit error rate, port data packet count, operating temperature, etc.; most of the current smart substations use layer 2 switches for the process layer network; the existing layer 2 switches cannot detect and sense in real time The online and commissioning status of the IED devices connected to each service ...
