Sensitivity requirements of reactive load division circuits in aircraft electric systems

Reactive load unbalance among paralleled generators is analyzed to relate the largest unbalance with the sensitivity of the reactive load division circuit employed in the regulators and with the regulation characteristics of the individual generator-exciter-regulator units. The maximum permissible sensitivity of the reactive load division circuit is found, from stability considerations, to be determined by the unsaturated synchronous reactance of the paralleled generators. The design of the reactive load division circuit is discussed from a system viewpoint.
