Considerations applicable to automatic paralleling of aircraft A-C generators

Practical and theoretical considerations relative to automatic paralleling of aircraft a-c generators are presented. Different types of a-c generator systems are classified generally as to requirements, and paralleling assumptions are proposed as design criteria. Synchronizing requirements as determined by subtransient and transient disturbance to the system, and paralleling requirements as determined by steady-state load division are presented. Considerations applicable to the development of autoparalleling systems are also discussed.
