Description

The system which is used for providing the necessary field current to the rotor winding of the synchronous machine, such type of system is called an excitation system. In other words, excitation system is defined as the system which is used for the production of the flux by passing current in the field winding.

Specification

The excitation may be controlled either manually by a base or dc regula- tor adjuster or automatically by the ac voltage regulator in response to the generator terminal voltage. The system may be configured to provide var or power factor control instead of terminal voltage regulation.
