Design and Implementation of an automatic voltage regulator of an engine generator set using microcontroller

Abstract

AC generators commonly use a combination Exciter-Voltage Regulation system to maintain generator field current under varying electrical loads. The basic voltage regulation system is designed to automatically regulate generator output terminal voltage within close tolerances of a specified value. The generic regulation system is a 'closed loop' feedback system in which generator output voltage is automatically compared to a reference voltage. The error signal is used to change generator excitation. The objective of this project to design and implement an Automatic Voltage Regulator for an engine generator set using
