A plug-and-play management method and system for a relay protection device

Abstract

The invention discloses a relay protection device plug-and-play management method and a system, belonging to the relay protection technology field. The relay protection device plug-and-play management method comprises steps of performing one-by-one whole box data one key automatic backup on all relay protection devices of a whole station when an intelligent transformer station operates in a good state, submitting backup files to a main station for management, downloading the backup files of the relay protection device from the main station when the relay protection device is faulted, and utilizing a deployment terminal to automatically recover the backup files to the faulted device through one key when replacement of a plug-in is finished. The invention guarantees the consistency of data information in the recovered device through a uniformity check-up, realizes the plug-and-play for the plug-in replacement, achieves the simplification of the operation and maintenance, improves the efficiency of the operation and maintenance, and guarantees the quality of operation and maintenance. Furthermore, the invention solves the problems that the plug-in configuration of the relay protection device of the intelligent transformer station is complicated and the replacement is hard once the a fault happens.

Description

technical field [0001] The invention relates to a plug-and-play management method and system for a relay protection device, belonging to the technical field of relay protection. Background technique [0002] There are many types of plug-ins for smart substation relay protection devices, and the composition is complex; each plug-in is composed of three layers: hardware, firmware (similar to operating system + protection program), configuration file (describing the virtual secondary circuit), especially CID, CCD, etc. The configuration files are very different for each device instance, and it is often required to download the corresponding firmware and configuration files on site according to the actual situation. [0003] At the same time, as a new thing, smart substation lacks relevant experience in equipment operation and maintenance, especially the operation and elimination of equipment, which puts forward higher requirements for operation and maintenance personnel.

Problems solved by technology

[0003] At the same time, as a new thing, smart substation lacks relevant experience in equipment operation and maintenance, especially the operation and elimination of equipment, which puts forward higher requirements for operation and maintenance personnel.

Considering the uneven professional level of the maintenance personnel, the wrong configuration may lead to the malfunction or refusal of the protection device, seriously affecting the safety of the power system
