Question

A 3 phase cylindrical rotor synchronous generators with its armature resistance and leakage

Answer 1

: Synchronous Machines Numericals

Q
A 3-phase cylindrical-rotor synchronous generators with its armature resistance and leakage reactance being neglected, is synchronized to an infinite bus and its field excitation is kept constant thereafter. Now the machine is loaded by supplying mechanical input to the shaft so that the load angle δ reaches a value of 60o under this condition, the operating power factor would be
