A 3-phase, 1000-MVA, 20-kV, 60-Hz synchronous generator is connected to an infinite bus as shown below. All impedances are given in pu values. The generator delivers 0.9 pu power at unity power factor to the infinite bus whose voltage is at 1 p
A 3-phase, 1000-MVA, \(20-\mathrm{kV}, 60-\mathrm{Hz}\) synchronous generator is connected to an infinite bus as shown below. All impedances are given in pu values. The generator delivers \(0.9\) pu power at unity power factor to the infinite bus whose voltage is at 1 pu.If phase 'A' of circuit 2 (CCT 2) between buses H1 and H2 is suddenly opened at point ' \(\mathrm{F}\) ' near bus H1 due to the opening of a circuit breaker, determine:(a) [10 marks] The internal voltage...
