b) Two synchronous generators, G2 and G2, are connected parallelly supplying a load. Generator G1 has a no-load frequency of 50.5 Hz and a slope of 300 MW/Hz. Generator G2 has a no-load frequency of 50.2 Hz and a slope of 500 MW/Hz. The load consumes 250 MW real power. (1) At what frequency does this system operate, and how much power is supplied by each of the two generators? (ii) An additional 100 MW load is added to this power system. What is the new system frequency, and how much power do G1 and G2 supply? (iii) The governor set point of G2 is changed to control system frequency back to 50 Hz. Determine the G2 governor set point.
The solution is largely correct but for a few errors.. Also note that the generator is represented by a voltage source and an impedance in series. Likewise the motor.please taking into consideration the following comment can you please resolve the question
. A 20 kW compound generator works on full load with terminal voltage of 250 V. The armature, series, and shunt windings have resistances of 0.05-ohm, 0.025 ohm, and 100 ohms, respectively. If the machine is connected short shunt, the emf generated is nearest to. (Our subject is Electrical Machines 1 ) (I need a clear answer and solution. Thank you so much)

Determine the air-gap flux, the flux density and the field intensity of the core and gap. Because of a fault in the power supply, the exciting current is increased to 8 A causing the mobile element of the iron core to move to a zero gap position as a result of the excessive electromagnetic force action.
