I was under the impression that the voltage fluctuations were more a result of the fundamental voltage drop of current flowing through resistance. (as opposed to the imbalance of demand/generation)
I.E. if your generating voltage (stepped up) is 69 kV, under a heavy load (or overload) you...
So to rehash this one more time.
Pin=Pout is really what I want to understand. At steady state let's say Pin = 100MW and Pout = 100MW. Now 1MW of load is lost. Examining this transient period of time - Pin is still 100MW because your generator has not had time to react.
Pout is still...
So during that brief time, the generator spins faster - effectively increasing the frequency, correct? And the mechanism by which the governor senses a loss of load is by monitoring that frequency?
I don't mean potential load exceeding potential generation.
I mean what happens if the instantaneous power produced on some pretend power grid was 100MW. The instantaneous demand at this time is also 100MW.
All of a sudden a large section of load is tripped offline and demand drops to 99MW...
Are you certain about that? From my (limited) power systems experience I was under the impression that if load exceeds generation the frequency will indeed begin to drop. (Voltage will drop as well just due to the increased voltage drop from higher currents).
Doesn't a typical utility have a...
I could rephrase the same question, why does the frequency decrease when load exceeds generation?
I know these are fundamental operating characteristics of a power system network but I'm not sure I can mathematically prove it. My best guess is that everything dissipates more power when the...
