A manufacturing plant takes 200 kW at 0.6 power factor, from 600 volts, 60-cycle 3 phase system. It is desired to raise the power factor of the entire system to 0.9 by means of a synchronous motor, which at the same time to drives a dc generator, requiring that the synchronous motor take 80 kW from the line. What should be the reactive power in KVAR of the synchronous motor?
