Dispelling the (irrational) fear or uncertainty about using GOOSE and all things IEC 61850 ...

Whether it is fear, or just ignorance … I often hear people say they don’t want IEC?61850. ??????♂???♂?
You might have noticed I usually jump in and generally “blow them out of the water” .. I apologise to those that may have suffered the barrage of my comments … I hope the reply did end up being useful.
But the fear and the nay-sayers (its good, but not on my watch …) are still out there …
So to put it all somewhere more “discoverable” and something easy for you to link to, I have pulled the key parts of the fear versus the far more rational imperative together here:

Of course you may think you know what IEC?61850 is …
but you might be surprised to learn what it REALLY is …, and what it really isn’t ….

Of course there are lots of my own papers to review: https://ideology.atlassian.net/l/c/2m1A4HY6
... and lots of CIGRE references (and a new Green Book about to hit the shelves in August 2022)
... and lots of great articles in the PAC World magazine (can you afford USD25/year?) https://www.pacw.org/
If it all still seems a bit scary, or daunting .. or has you intrigued and excited .. please reach out to me for further assistance.

2 年Power system protection with analog technique is not better than standardized digital technique (read IEC 61850). The difference is that in the analog world we have the solutions to the problems that we may face, and if I do not have the solution, I know my colleagues have it. Example? The trip circuit (from the relay trip contact to the circuit breaker trip coil) is not so reliable as many say. If it was, why should we have invented the "trip circuit supervision"? Trip circuit supervision is "odd" to implement. It makes many things more complicated. In GOOSE the "trip circuit supervision" is much simpler, but if the TRIP GOOSE gets trapped in the Ethernet switch because of wrong VLAN configuration, this makes people nervous. Again, the solution is simple, but you need to have experience to know it and implement it.

2 年I think that the "irrational fear" has nothing to do with IEC 61850. It has to do with us, engineers and humans: we don't like to handle things that we don't know, and especially engineers don't like to have to do with things that have problems but their solutions are unknown. This knowledge is based on experience. Very few do "pioneering". Pioneering is when you show to others that "it can be done". Later on the "others" will also do it, because there is the confidence that it can be done.

2 年At the end I think it will happen what has already happened in other circumstances: generational change will get new engineers ask this question in their company: "why don't you use IEC 61850?" instead of today's question: "why should I use IEC 61850?".

2 年I appreciate your efforts in promoting this new technology (more than 18 years old... but still new)!

2 年I think also the industry (read "equipment vendors" and "WG10") still has much work to do, as implementation in devices have shortcomings. 3 things I think every device must support are: configurable LDs, the ability to control the mode of LDs, and configurable prefixes for LNs and LDs. I'm working on a specific project where the utility needs all 3 of these, but their vendors don't support them. To me, configurable prefixes are vital. We will, for the foreseeable future, use GGIO on projects, mostly because of custom logic used in devices, or shortcomings in the 61850 model. If I have to use GGIO, I want to be able to modify the prefix so I can give it some semantics, and no device I have looked at permits this. [Yes, Rod, I know GGIO is to be avoided. And yes, I know there is work being done on logic modeling in 61850. But for the time being, we're stuck with GGIO in a lot of circumstances, so we should make it more usable.] And yes, there are some shortcomings in the 61850 model - I have a small example in mind, but I'm going to leave it for now.?? /end
