I'm an EE with a lot of digital logic / VLSI design knowledge under my belt, but I made a big change to work for a utility. I'd like to bone up on power systems. I know with "electronics" in the name, this group is perhaps not the appropriate place to ask, but can anyone recommend a good text on power systems?
In particular, I want to understand a bit more how impedances and power flows are modeled/calculated without respect to voltage, using the "per unit" system. This seems to be the norm in power engineering because transformers are all over the place with all kinds of ratios, and rather than keep track of all that, they seem to just "reflect" impedances over to one reference node.
I think.
Any recommendations?
thanks, Dave J
