Using the 2 different 'single phase equivalent circuits' given below, the desired equations will be deducted. Equations separately for asynchronous motor powered by voltage source will be removed and the spaces given below will be written. You can also do your inference work. show it and deliver it. V1 and I1 are the RMS value of the AC phase voltage and current. All formulas (3 phase motor) will be written as a function of motor parameters and slip.

can you calculate the efficiency of the alternator

Q2. a) A 415V, 50Hz, 3-phase induction motor supplies its rated power to a load. The rated speed of the motor is 980 rpm. 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. (i) 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.
