Use the following transfer function G(S) :
(s+2)(s+8)(s+9)*
Using signal-flow graphs, represent
the system in parallel, cascade, controller canonical, and observer canonical forms, as well as in
phase variables.
A3 φ, 10 kVA, 220 V, four-pole, 60 Hz, star-connected synchronous machine has negligible stator winding resistance and a synchronous reactance of 6 ohms per phase at rated terminal voltage. The machine is first operated as a generator in parallel with a 3φ, 220 V, 60 Hz power supply.
(a) Determine the excitation voltage and the power angle when the machine is delivering rated kVA at 0.8 PF lagging.
(b) If the field excitation current is now increased by 20 percent (without changing the prime mover power), find the stator current, power factor, and reactive kVA supplied by the machine.
