Two 3 Phase 11kv Delta Connected Synchronous Generators Operate In Parallel Supplying A Common Load Of 2mw At A Power 1 (59.64 KiB) Viewed 44 times

Two 3-phase, 11kV delta-connected synchronous generators, operate in parallel supplying a common load of 2MW at a power factor of 0.8 lagging. The prime-mover governors are so set that the mechanical load is shared equally between the two machines. The synchronous impedance of the two generators are as follows: Synchronous impedance of generator 1:(0.39 + j1.97) 12 Synchronous impedance of generator 2: (0.5 +j1.5) 12 If generator 1 excitation current is adjusted so that it delivers 100A per phase at a lagging power factor: Q- Determine the magnitude of excitation voltage(E) of generator 1.
