Alternator Excitation Control Systems and Methods
Excitation systems are the systems that supply field current to a alternator's rotor winding. Excitation systems that are well-designed give operational dependability, stability, and quick transient response. Shunt or Self ExcitedExcitation Boost System (EBS)Permanent Magnet alternator (PMG)Auxiliary Winding (AUX). Each strategy has its own set of advantages. To deliver DC output to the exciter stator, all techniques employ an Automatic Voltage Regulator (AVR). The AC output of the exciter rotor is rectified to a DC input for the main alternator rotor. More complex systems employ a second AVR input. This article will go into the construction, function, and application of…
