A method for subscribing goose/smv messages, a configuration module and a subscriber

Abstract

The invention relates to the technical field of electric power automation communication, in particular to a method for subscribing to GOOSE / SMV messages. The method sets the working mode of the network card of the subscriber to the mixed mode, receives all the communication messages sent by the publisher, screens the GOOSE / SMV messages from them, and analyzes them one by one to obtain the subscription feature information of each message, and presents it to On the user interface: the user selects a specific message item and forms its corresponding feature information into a persistent file; the subscriber uses the subscription feature information contained in the persistent file to subscribe to the required GOOSE / SMV message. The invention does not rely on model files at all, completely avoids subscription failures caused by model errors or inconsistencies between models and actual messages, and improves subscription accuracy. And compared with the method of directly using SCD / CID file subscription, it reduces the memory occupied during the system startup process and speeds up the system startup speed.

Description

technical field [0001] The invention relates to the technical field of electric power automation communication, in particular to a method for subscribing GOOSE / SMV messages, a configuration module and a subscription terminal applied in the field of intelligent substations. Background technique [0002] At present, the IEC61850 standard has been widely used in smart substations, among which, GOOSE / SMV communication is an important part of it, and the bay layer device needs to subscribe to the GOOSE / SMV message from the process layer device. Usually, based on the IEC61850 standard, the system integrator first provides the SCD file required on site, and then further separates the CID file of each device, and the subscribing device directly uses the SCD file or uses the CID file of the required device to determine the GOOSE / SMV report. The detailed information of the message is used as the main basis for subscribing to the message. [0003] However, due to changes in user needs...

Problems solved by technology

[0003] However, due to changes in user needs, design changes, and correction of design errors, etc., the site often leads to frequent revisions of SCD files. The understanding is not in place, and the IEC61850 standard does have ambiguities, or the wrong version of the model is given due to busy debugging work, which often causes inconsistencies between the GOOSE / SMV message actually released by the publisher and the model given offline In this situation, the subscription information determined by the subscriber based on the model is inconsistent with the actual message, resulting in the common error of always failing to subscribe

The developers on the subscriber and publisher side spend a lot of time carefully checking the subscription information and confirming the details of the subscription, and the workload is also huge

These have greatly affected the construction efficiency

[0004] When subscribing to GOOSE / SMV messages by directly using the SCD / CID file, since the SCD / CID file must follow the file format specified in the IEC61850 standard, and this format is very complicated, the subscriber loads and parses the SCD to subscribe to the GOOSE / SMV information When / CID files need to process complex file structures, the processing process often takes up a lot of memory and greatly prolongs the startup time of the subscriber
