Plug-and-play configuration method for distributed bus protection main and sub-machines, main machine and sub-machines

Abstract

The invention discloses a plug-and-play configuration method for distributed bus protection main and sub-machines, the main machine and the sub-machines. The method is executed at the sub-machines and comprises the steps of: receiving sub-machine serial numbers, wherein the sub-machine serial numbers are used for self identity recognition, the sub-machines located at different intervals have different sub-machine serial numbers, loop virtual terminal connection configurations (CCD configuration) are stored in the sub-machines, protection programs are stored in the sub-machines, and GOOSE tripping commands of a host to all intervals are stored in the CCD configurations stored in the sub-machines; receiving a GOOSE tripping command issued by the host; and judging according to the sub-machine serial numbers by the protection programs. One sub-machine number is set for each sub-machine protected by a distributed bus, a universal main and sub-machine communication CCD configuration file is preset in the device, one protection program carries out identity recognition according to the sub-machine numbers, the CCD configurations are automatically rewritten according to agreed rules, and flexible expansion and plug and play between a main machine and interval sub-machines are achieved.

Description

technical field [0001] The invention relates to the technical field of distributed busbar protection systems, in particular to a plug-and-play configuration method for distributed busbar protection main and submachines, and the mainframe and submachines. Background technique [0002] A set of distributed busbar protection device is composed of 1 main unit and n sub units. As the acquisition and execution unit, the slave machine is configured according to the interval. The slave machine collects the analog information (such as current, voltage, etc.) position, failure switch input, etc.) are sent to the host by GOOSE message, and the host acts as the central processing unit. After receiving the analog and switch information sent by the slave, it performs logical operation processing, outputs a trip command and sends it through the GOOSE message For the sub-machine, after receiving the GOOSE trip command issued by the host, the sub-machine drives the local hard-open contact t...

Problems solved by technology

[0005] Each interval sub-machine must send SV and GOOSE messages to the host, but the IEDName of each sub-machine, APPID and other parameters for issuing SV and GOOSE messages are not allowed to be repeated, otherwise the main and sub-machines will not be able to communicate normally.

[0006] Due to the large number of sub-machines in a set of distributed bus protection, if the CCD configuration of each sub-machine is different, it will cause difficulties in production, debugging and configuration management. CCD configuration, unable to achieve plug and play
