Interrelationships among fault torque, voltage unbalance, fault current, and generator impedances of aircraft electric power systems

AMONG the many problems facing those working with aircraft electric power systems is that of satisfying requirements with respect to voltage and current during fault or unbalance conditions, while limiting the torques imposed on the constant-speed drive. It is the purpose of this paper to present a method for obtaining and depicting the interrelationships which exist among these several quantities such that a basis for evaluation in system design may be achieved. The method should help the system engineer and generator designer to arrive at a compromise, giving the best possible system performance in terms of these performance characteristics and generator weight.
