A 700 kW, 60 Hz generator A, with 2.0% speed regulation, is operating in parallel with generator B of equal kW rating, but whose speed regulation is 6.0%. The total bus load of 1000 kVA at 60 Hz, 2400 V, and 80% power factor lagging is divided equally between the two machines. If a 200-kW load is disconnected from the bus, determine the new operating frequency and the active power load on each machine.
