Question: m a generator is feeding an infinite bus through transfer...

Question details

m: A generator is feeding an infinite bus through transfer line J as shown in the Figure. gging. In point A there is a zero resistant fault that causes s after the fault. It can be presumed that the fault is cleared while generators power is p-0.8 and cosp 0.85 la the break the breakers are open. Calculate: ers Ki and K2 to open 0.1 a) The line current before the fault occurs (using power and pf). Internal voltage of the generator and its phase angle, considering the infinite bus voltage as a reference b) c) The power-angle equation d) the critical clearing angle at which the breakers must be re-closed at the latest to maintain stability.
