Automatic Voltage Regulator Block Diagram

It takes the fluctuate voltage and changes them into a constant voltage.

Automatic voltage regulator block diagram. The automatic voltage regulator is used to regulate the voltage. An automatic voltage regulator. The automatic voltage regulator works on the principle of detection of errors. The input voltage is sensed by the microcontroller and it tries to keeps the output voltage between its specified ranges by switching the relays.

It controls the voltage of the system and has the operation of the limit nearer to the steady state stability. The microcontroller generates the control signals and four relays are used with the autotransformer for the control and conversion of voltage. Excitation system the equipment that contains control and power elements which provide the required field current to. Here is how it works.

The automatic voltage regulator is used to regulate the voltage. The block diagram to the right illustrates the basic concepts used in stabilizing the output of gensets with self excited alternators. It takes the fluctuates voltage and changes them into a constant voltage. It basically consists of a main exciter which excites the alternator field to control the output voltage.

The variation in voltage damages the equipment of the power system. Automatic voltage stabilizer working. The fluctuation in the voltage mainly occurs due to the variation in load on the supply system. Automatic voltage control figure 8 20 gives the schematic diagram of an automatic voltage regulator of a generator.
