Automatic Voltage Regulator (AVR) is a device designed to regulate voltage automatically. It takes the fluctuate voltage and changes them into a constant voltage. The fluctuation in the voltage mainly occurs due to the variation in load on the supply system. The variation in voltage damages the equipment of the power system. The variation in the voltage can be controlled by installing the voltage control equipment at several places likes near the transformers, generator, feeders, etc., The voltage regulator is provided in more than one point in the power system for controlling the voltage variations.
AVR – to take a fluctuating voltage level and turn it into a constant voltage level.
What is the function of an AVR?
The function of the Automatic Voltage Regulator (AVR) is to maintain constant voltage and power line conditioning to the equipment load under a wide variety of conditions, even when the utility input voltage, frequency or system load vary widely.
What is meant by voltage regulation?
The voltage regulation is the percentage of voltage difference between no load and full load voltages of a transformer with respect to its full load voltage. Explanation of Voltage Regulation of Transformer: Say an electrical power transformer is open circuited, means load is not connected with secondary terminals.
How does an AVR work?
An Automatic Voltage Regulator (AVR) is an electronic device for automatically maintaining generator output terminal voltage at a set value under varying load and operating temperature. It controls output by sensing the voltage V-out at a power-generating coil and comparing it to a stable reference.
Why is voltage regulation necessary?
The voltage regulator is needed to keep voltages within the prescribed range that can be tolerated by the electrical equipment using that voltage.
What are the features of AVR?
- It controls the voltage of the system and has the operation of the machine nearer to the steady state stability.
- It divides the reactive load between the alternators operating in parallel.
- The automatic voltage regulators reduce the overvoltage’s which occur because of the sudden loss of load on the system.
- The automatic voltage regulators reduce the overvoltage’s which occur because of the sudden loss of load on the system.
- It increases the excitation of the system under fault conditions so that the maximum synchronising power exists at the time of clearance of the fault.
