Draw a schematic diagram of a per-phase synchronous

Question

Part -1:

a) Discuss the methods used for finding the approximate transformer parameters R_ser, L_ser, R_par and L_par.

Part -2:

a) Draw a schematic diagram of a per-phase synchronous electrical generator.

b) Define the components in the armature stator side of the diagram.

e) Define the generator's torque components.

d) Define the generator's power components.

A 3-phase, 600 kVA synchronous generator has a rated line voltage of 3300 V. The stator winding is star connected and has a resistance of 0.37 Ω/phase. Its synchronous impedance is 4.3 Ω/phase.

e) Draw the synchronous generators per phase voltage and current phasor diagram.

I) Calculate the per phase output voltage.

g) Determine the voltage dropped across the synchronous impedance.
