Disrespectful Sampled Values subscriber behaviour
Disrespectful Sampled Values subscriber behaviour

Teaser: Some IEDs require that SV (or maybe GOOSE) messages on ingress port of the IED have proper VLAN tag (as configured in the subscription), thus resulting in failure to receive the untagged messages (or messages with another VLAN ID tag). Such behaviour of an IED is wrong but sometimes you can meet this. Read the full article to dig into the details.

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.

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.

Software Based Centralized Protection: commissioning experience
Software Based Centralized Protection: commissioning experience

In 2018 Tekvel signed several contracts to commission centralized protection system based on servers and independent software. In this article we would like to share our experience and discuss some of the problems, that might require special attention from utilities on the way to mass deployment of centralized PAC systems.
