PSS/E Modelling
PSS/E Modelling
(OP)
Hey everyone - came across this forum and am hoping to get involved. I am a recent graduate from Engineering Physics and I have landed a job in a local utility. I'll be the first to admit, I probably don't have the "power" experience that an EE would - eager to learn though!
In preparation, I am trying to up my experience in PSS/E. I have downloaded the University version (which is free up to 50 buses). I can't seem to find much of anything online in terms of tutorials, so I thought I would ask here. Is there a way to include and model specific relay characteristics in PSS/E? For the life of me, I can't figure out how to add, let along model, a relay. Also, would adding relays necessitate the addition of CTs/PTs?
Thanks! (sorry if my questions are basic)

RE: PSS/E Modelling
Before spending too much time learning PSS/E, find out what software your utility uses. Your new employer may be willing to pay for some training on their software.
RE: PSS/E Modelling
They do use PSS/E and training is provided, however, I don't start till May of next year. As such, I have a bit of time. I figure I might as well learn as much as I can now.
I was told this: PSS/E models the characteristics of distance relays in terms of "straight-line blinders" and "circles" particularly for transient simulations.
Can someone shed light on this? I understand the concept of transient simulations, but what what straight line blinders and circles, and where/how does PSS/E model this?
Thanks again
RE: PSS/E Modelling
I am in no means presuming to judge your starting level of knowledge, but I would think an important focus should be learning relaying and power system fundamentals (especially if you haven't had many courses in those) before diving into software.

If you're going to be doing this for a living, buy a copy of "Protective Relaying" by J. Lewis Blackburn. Also see:

RE: PSS/E Modelling
There is a good list of references here:
FAQ238-1287: What are good references for a Power Engineer?
Many of them are free on-line. That includes GE's Art and Science of Protective Relaying (with a chapter on distance relays), also some good free references from Areva T&D and others.
