(b) A 50 Hz synchronous generator with inertia constant H = 6.2 MJ/MVA is connected to an infinite bus through a purely reactive circuit, as illustrated in Figure Q5(b). The generator is delivering real power P3 = 0.950 pu and Q3 = 0.713 pu to the infinite bus at a voltage of V3 = 1.0 pu. A temporary three-phase fault occurs at the receiving end of Line 1 at point F. When the fault is cleared, both lines remain following the disturbance. Propose the stability limit of the system by determining the critical clearing angle (8.) and the critical fault clearing time (tc) for the given disturbance.

A circuit is constructed with an AC generator, a resistor, capacitor and inductor as shown. The generator voltage varies in time as ε = Va - Vb = εmsinωt, where εm = 120 V and ω = 429 radians/second. The values for the remaining circuit components are: R = 61 Ω, C = 426 μF. The value for L is unkown. What is known is that the voltage across the generator leads the current in the circuit by φ = 48 degrees. 1) What is t1, the first time after t = 0 when the magnitude of the voltage across the inductor is maximum? 4) What is VL,max, the magnitude of the maximum voltage across the inductor? 5) What is VL = Vb - Vc, the voltage across the inductor, at time t = 0? Note that VL is a signed number.
