Question

Electrical Engineering

a) Give TWO (2) types of rotor in synchronous machine anddescribe the differences of these two rotors.

b) A three-phase 11kV, 12 MVA, 50 Hz, 4 poles, Y-connected, 0.9power factor lagging synchronous generator has a synchronousreactance and armature resistance of 0.05 Ω and 0.4 Ω per phaserespectively. Under full load condition, the friction and windagelosses are 60 kW and the core losess are 39 kW. Determine:

i) The generator speed at no-load condition in rpm

ii) The magnitude of the phase and line current

iii) The internal emf generated and power angle

iv) The voltage regulation

v) The maximum power and converted torque
