Abstract:
1. An excitation system for a power generation system, comprising: an exciter, said exciter generating a field voltage for exciting a rotor of said power generation system; a first automatic voltage regulator, said first automatic voltage regulator receiving an output voltage of said power generation system as an input; and a second automatic voltage regulator, said second automatic voltage regulator receiving said field voltage as a first input; wherein an output of said first automatic voltage regulator is provided as a second input to said second automatic voltage regulator, wherein said first automatic voltage regulator is in selective electrical communication with said exciter through a first line conductor having first separable contacts such that an output of said first automatic voltage regulator may be selectively provided as an input to said exciter, and wherein said second automatic voltage regulator is in selective electrical communication with said exciter through a second line conductor having second separable contacts such that an output of said second automatic voltage regulator may be selectively provided as an input to said exciter.
