Intelligent transformer station configuration file standardized management system and file verification method

Abstract

The invention discloses an intelligent transformer station configuration file standardized management system comprising a server terminal which is arranged in a scheduling department and configuration management client-terminals which are arranged in all intelligent transformer stations. The multiple configuration management client-terminals are communicated with the server terminal via a scheduling data network. Management flow of an SCD file is standardized, the intelligent transformer station SCD file can be locally analyzed, and the SCD file can be verified via auxiliary verification functions like shema verification, model static verification and model dynamic verification so that correctness, rationality and integrity of the SCD file are ensured. Besides, the SCD file of each intelligent transformer station is uploaded to the server terminal to be managed in a unified way so that an effective tool for managing and inspecting a configuration file is provided for a transformer station operation maintenance unit, proper use of the configuration file in the processes of construction, acceptance, operation maintenance and enlargement of the intelligent transformer stations is facilitated for basic technical personnel, reliable operation of the intelligent transformer stations is ensured, and thus the system can be widely applied to all levels of electric power scheduling centers.

Description

technical field [0001] The invention relates to an intelligent substation configuration file management system and a file verification method, in particular to a smart substation configuration file standardized management system and a file verification method. Background technique [0002] SCD file, also known as smart substation overall configuration file, as a unified data source for the whole station, describes the instance configuration and communication parameters of all IEDs in the smart substation, the communication configuration between IEDs and the interconnection information of virtual terminals, etc. The design, commissioning, operation, and maintenance of smart substations are of great significance. [0003] With the continuous acceleration of the construction of smart substations, the standardized management of SCD files as the core configuration files of smart substations has been put on the agenda, but there are many irregular behaviors in the management of ex...

AI Technical Summary

Problems solved by technology

[0004] 1) The review of the SCD file format is not strict, and the IED model does not follow the requirements of relevant standards, such as "Q / GDW 396 IEC 61850 Engineering Relay Protection Application Model";

[0005] 2) Only modify and download the configuration of a single IED, but ignore the download of other related IED configurations, resulting in communication problems between IEDs;

[0006] 3) The actual model of the IED device is inconsistent with the description in the SCD file;

[0007] 4) Unauthorized modification of SCD files without backing them up in time, resulting in multiple SCD files in the site and confusing versions;

[0008] 5) The technical level of each power supply unit is uneven, resulting in loopholes in the acceptance and management of SCD files, which brings a lot of inconvenience to operation and maintenance and expansion work, and brings hidden dangers to safe operation
