When GOOSE can't fly!
When GOOSE can't fly!

Everyone who ever dealt with the commissioning of IEC 61850 based systems had situations when there were problems in establishing successful GOOSE communications between IEDs. The reasons for that are always different. There may be a fault of the commissioning engineer, a fault of the vendor or it may be a fault of both parties at the same time. We have faced such situation recently and this was the case when one could blame... decide yourself who is to blame in this situation, having read this note about nuances in configuring GOOSE-communications between IEDs of two different vendors.

Transmission of data structures in a GOOSE message
Transmission of data structures in a GOOSE message

GOOSE-messaging has been covered a lot in many technical papers and to add anything valuable to the subject is rather difficult. But we will try. And functional constrained data will help us with that.

Quality Assurance requirements and experiences for GOOSE/SV configuration

The paper describes our experiences in applying quality assurance principles during the off-line SCL engineering phase independent of the engineering tool or Excel files used. These principles include requirements for inspection, visualisation and detailed analysis of the configuration of the GOOSE and SV communication all directly from the SCL files. The results of these processes are presented in regards to optimised data flow, identification of unpublished or unsubscribed GOOSE/SV, restriction of use of generic Logical Nodes and generic signal names ensuring better overall performance and reliability.
