Relay protection, SCADA, Metering, and Cybersecurity for electrical infrastructure.
A contractor hands over an SCD file claiming it matches the actual device configuration. But how do you verify that quickly and provably when there are 76 IEDs on site and no permanent monitoring system? A field case from Tekvel: the verification module in the Tekvel Magic software automatically compared the device configurations against the SCD and produced an engineering deviation report covering DataSets, GOOSE, Sampled Values and MMS reports in 15 minutes.
There is quite a few projects we've met, where each IED publishes single GOOSE message with huge dataset instead of having several GOOSE. We decided to understand which solution is preferrable?
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.
В предыдущей публикации [1] мы рассмотрели один из важных и наиболее обсуждаемых коммуникационных протоколов, описанных стандартом МЭК 61850 — протокол GOOSE, — предназначенный для передачи, в первую очередь, дискретных сигналов между устройствами релейной...
