Automatic Voltage Regulator

AVR (Automatic Voltage Regulator) plays a key role in generating stations. To maintain voltage stability of the generator the terminal voltage should remain constant all the times. In a large interconnected system manual regulation is much complicated and therefore automatic generation and voltage regulation is necessary. So, to maintain a constant voltage level, Automatic voltage regulators are used at each generating station. Generally the voltage fluctuation is mainly due to the variation in the load and if there is a variation in the voltage then it can damage the equipment so it is necessary to stabilize there voltage so automatic voltage regulator is used in the system to stabilize the voltage or to regulate the voltage.
