Ok i think i got it. :)
You just have to ask: ¿Will the lier door lead me to death?
Then just take the door of the guard that would say yes.
Explanation: You don't really know who tells the truth and who lies, but here's the trick.
D is death door. F is freedom door.
1. If the lier is...
I'm a total newbie on this, but from what i've read, you need to express all variables as a state space variable if you want to use them in a state space form. For example, when you want to incorporate an excitation system into a SMIB model, you have to express the variables of the excitation...
I'll try to use the perspective of power. As far as ii know, a conductive predominant circuit has positive reactive power, so S=P+jQ. Now, in per unit, we have S=VI*
By substituting terms I=S*/V* which means I=(P-jQ)/V*
S=P-jQ gives you a negative angle so current lags voltage, if you want to...
I've been searching everywhere for useful info about this topic, but I haven't been able to find anything.
My question is: Is it viable to tune a PSS by using time domain?
The thing is, i don't know how you can associate the frequency range in which the PSS is needed for...
