GOOSE/SMV (generic object oriented substation event/sampled measured value) message subscribing method, GOOSE/SMV message subscribing configuration module and GOOSE/SMV message subscribing terminal

Abstract

The invention relates to the technical field of automated power communication, in particular to a GOOSE / SMV (generic object oriented substation event / sampled measured value) message subscribing method. The method includes the steps: an operating mode of a network adapter of a subscribing terminal is set into a mixed mode to receive all communication messages that a release terminal sends out, GOOSE / SVE messages are screened from the communication messages and are analyzed item by item to obtain subscription feature information of each message, displayed on a user interface; a user selects the certain message item and forms the corresponding feature information into a persistent file; the subscribing terminal subscribes to the required GOOSE / SMV messages through the subscription feature information included in the persistent file. The method has the advantages that the method is independent of model files, subscription failure caused by model error or inconsistence between models and actual messages is thoroughly avoided, and subscription accuracy is improved; compared with a method for subscribing to messages directly through SCD / CID (substation configuration description / configured IED description) files, the method ensures that less memory is used during system startup and that system startup is faster.

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
