Three synchronous generator are connected in parallel to a an infinite s. G1 only provides active power by sp1=1MW/Hz and fnl=61.5Hz. G2 ly provides reactive power by sq2=0.2MVAr/V and vnl =482 V. G3 is oviding active power with sp3=0.8MW/Hz and fnl =61 Hz and also a active power by sq3=0.6MVA//V and vnl =481. if the infinite bus determines system frequency as 60 hz and the bus Itage as 480 find the active and reactive power of all generators. If G3 is working at its rated power, find a new fnl and vnl that G3 ovides its maximum active power to the system.

Question

Please provide Handwritten answer

2) Three synchronous generator are connected in parallel to a an infinite
bus. G1 only provides active power by sp1=1MW/Hz and fnl=61.5Hz. G2
only provides reactive power by sq2=0.2MVAr/V and vnl =482 V. G3 is
providing active power with sp3=0.8MW/Hz and fnl =61 Hz and also a
reactive power by sq3=0.6MVAr/V and vnl =481.
a) if the infinite bus determines system frequency as 60 hz and the bus
voltage as 480 find the active and reactive power of all generators.
b) If G3 is working at its rated power, find a new fnl and vnl that G3
provides its maximum active power to the system.
