4. Two alternators A and B are in parallel and supplying a 600- V,60 Hz bus load consisting of a 270 kVA unity power factor load a group of induction motors totaling 420 kVA at 89.4 percent power factor and a synchronous motor that draws 300KVA at 92.3 percent power factor leading. If the machine A is carrying 60 percent of the total active power load at a power factor of 70.4 percent lagging, determine the active and reactive components supplied by machine B.

270 kVA unity power factor load a group of induction motors
totaling 420 kVA at 89.4
percent power factor and a synchronous motor that draws
300KVA at 92.3 percent power
factor leading. If the machine A is carrying 60 percent of the
total active power load at a
power factor of 70.4 percent lagging, determine the active and
reactive components supplied
by machine B.
