A three phase synchronous generator operates onto a grid bus of voltage 33 kv (line to line). The armature reactance of the machine is 2 ohms per phase and the leakage reactance is 3 ohms per phase. The magnitude of the generator equals the magnitude of the bus voltage. The machine delivers 36 MW to the grid? Find
a). The power angle (delta)
b). phase current, magnitude and phase relative to V1
c). magnitude and direction of reactive power.
d). draw the equivalent circuit of the machine and the phasor-vector diagram listing all details like constant power loci of I1, and the constant power loci of Ef
