Integrated platform of configuration protection and engineering configuration of digital transformer substation

Abstract

The invention discloses an integrated platform of configuration protection and engineering configuration of a digital transformer substation, which is characterized by comprising an imaging device function configuration module, an IEC 61850 modeling configuration module and a secondary equipment networking module of a transformer substation, wherein the imaging device function configuration module is used for imaging configuration, automatically generating protection based on the C language after configuration and simultaneously generating a device function description configuration file provided for the IEC 61850 modeling configuration module to use; the IEC 61850 modeling configuration module is used for managing configuration files of the whole transformer substation and carrying out secondary instantiation and private configuration mapping through the device function description configuration file output by the imaging device function configuration module; and the secondary equipment networking module of a transformer substation is used for finishing the GOOSE communication configuration of a single device or devices of the whole station and outputting a GOOSE dummy terminal signal list. The invention can quickly meet different requirements of different users to realize the protection of flexible configurations and quick configuration so as to improve the on-site engineering debugging efficiency of the digital transformer substation.

Description

technical field [0001] Aiming at the problem of how to solve the protection configuration and engineering configuration in the digital substation of the electric power system to quickly respond to on-site requirements, the invention proposes an integrated platform for the protection configuration and engineering configuration of the digital substation, which belongs to the technical field of electric power system digital substations. Background technique [0002] After more than 20 years of development of relay protection devices, the site has more and more functional requirements for protection devices, making the current protection software functions more and more complicated, increasing the difficulty of software maintenance, and it is difficult for general engineering debuggers to fully grasp the design principles. The difference between the digital substation and the traditional substation is that the configuration of the digital substation is very flexible, and the one-...

AI Technical Summary

Problems solved by technology

Since the digital substation adopts the IEC61850 standard, it is possible to achieve interoperability between the equipment of various manufacturers. However, there is no standard agreement on the format between the GOOSE communication configuration and the IEC61850 path mapping to the private internal data of the manufacturer.

This leads to the fact that each manufacturer has its own independent configuration file tool during the commissioning process, and a digital substation often integrates protection products from multiple manufacturers. The configuration of GOOSE communication in the whole station is cumbersome and needs to be performed by different configuration tools of each manufacturer. Import and export common configuration parts, making it difficult to track and manage mutual versions
