I’m a protective relay settings engineer at a contractor for lots of power companies. I’m dipping my toes into my first substation automation project. Getting to design the device native files, IPs, and other networking parts from the drawings package of site and device manuals. It’s all SEL equipment with a gateway at the top and local powerWAN, RTAC, annunciators, and relays below. I live thousands of miles from the site, so local testing would be challenging but probably have to fly or something lol. I have been doing some research on how to emulate this is a lab setting when all you have is the RTAC and some relays. Is this something SCADA engineers have to do sometimes? Like if you need to test a scheme when you can’t build it physically first?
