6.4.2 Load Division. When generators are operated in parallel,
proportional division of the electric load (kW) depends on the power
supplied by the engine which is controlled by the speed. However, reactive
Kilovoltampere Reactive Power (KVAR) division is shared according to
generator excitation. Provisions to adjust excitation for kvar sharing in
the generator control is called crosscurrent compensation. Crosscurrent
compensation is provided by each current transformer supplying each voltage
regulator and acts to limits each generator's share of the total kvar
required. The load is proportionally shared to each generator's rating.
