Problems solved by technology
Process layer configuration files cannot be unified due to the influence of different hardware structure designs and platform designs of various manufacturers
It is precisely because of the existence of process layer configuration files that different manufacturers must use their own device instance configuration tools to generate CID (configured IED description, IED instance configuration file) and corresponding process layer configuration through SCD (substation configuration description, total station system configuration file) files, which makes the substation commissioning and maintenance process very complicated, and relies too much on equipment manufacturers

Embodiment Construction
[0016] The content of the present invention will be further described below in conjunction with the accompanying drawings.
[0017] Such as figure 1 As shown, this embodiment provides a maintenance method for a relay protection device in a smart substation, including the following steps:
[0018] S100 obtains the standard hierarchical model of the relay protection device to be repaired in the smart substation;
[0019] S200 Acquire the standardized GOOSE / SV communication interface and the standardized GOOSE / SV information flow of the relay protection device to be overhauled;
[0020] S300 Establish a mirror image device of the relay protection device to be repaired according to the standard hierarchical model, the standardized GOOSE / SV communication interface, and the standardized GOOSE / SV information flow;
[0021] S400 Switch the link between the process layer equipment and the relay protection device to be repaired to the link with the mirror device, and perform repairs o...

The invention relates to an overhauling method of an intelligent substation relay protection device. The overhauling method comprises the following steps of obtaining a standard layering model of the relay protection device to be overhauled in an intelligent substation, obtaining a standardized GOOSE / SV communication interface and standardized GOOSE / SV communication information flow of the relay protection device to be overhauled, establishing a mirroring device of the relay protection device to be overhauled according to the standard layering model, the standardized GOOSE / SV communication interface and the standardized GOOSE / SV communication information flow, performing switching from a link between a process layer device and the relay protection device to be overhauled to a link of the mirroring device and overhauling the relay protection device to be overhauled. By means of the overhauling method, a primary device is not needed to perform auxiliary stop, outage time is shortened, and power supply reliability is improved. In addition, the safe measure process of overhaul operation is simplified. Technical support from device production manufacturers is not needed in the overhauling process.
Description
technical field [0001] The invention relates to the technical field of intelligent substations, in particular to a maintenance method for relay protection devices of intelligent substations. Background technique [0002] Smart substations have been widely promoted and constructed after development in recent years, so the relay protection equipment of smart substations is also facing a lot of maintenance work. However, there are many problems in the maintenance of relay protection equipment at present, such as the inability to achieve complete blackout construction during the maintenance process, and the crux of the unprotected operation of primary equipment during the maintenance of relay protection equipment. [0003] Due to the wide variety of protection devices in smart substations, the use and operation of the devices are different. At present, the association between the physical ports of the relay protection devices and the actual data flow is mainly realized through t...
