AVR- AUTOMATIC VOLTAGE REGULATOR
AVR is a device used to measure any difference in the
generator terminal voltage and highly stabilized reference
value, and if it detects any difference, it controls the
firing pulses of the thyristors connected in the
system.....to change the output voltage of the pilot
exciter which in turn changes the output of the main
exciter n ultimately the generator voltage........
IN SHORT, IT IS USED TO MAINTAIN THE GNEREATOR TERMINAL
VOLTAGE B/W THE TRANSIENT STABILITY LIMITS so that d
generator remains in synchronism
