Working Principle of Voltage Regulator

The automatic voltage booster works on the principle of detection of errors. The single phase step voltage regulator obtained through a potential transformer and then it is rectified, filtered and compared with a reference. The difference between the actual voltage and the reference voltage is known as the error voltage. This error voltage is amplified by an amplifier and then supplied to the main exciter or pilot exciter.Thus, the amplified error signals control the excitation of the main or pilot exciter through a buck or a boost action (i.e. controls the fluctuation of the voltage). Exciter output control leads to the controls of the main alternator terminal voltage.

A regulator regulate the voltage

The automatic voltage regulator is used to regulate the voltage. The auto load booster 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.In DC supply system the step voltage stabilizer can be controlled by using over compound generators in case of feeders of equal length, but in the case of feeders of different lengths the voltage at the end of each feeder is kept constant using feeder booster. In AC system the voltage can be controlled by using the various methods likes booster transformers, induction regulators, shunt condensers, etc.

high voltage auto load booster in the utility’s distribution systems

The power distribution system applied to utilities is generally the high voltage auto load booster (SVR). It should be noted that there are two different types of ac automatic load supercharger: medium-voltage cascade voltage regulator (mechanical) and low-voltage regulator (mechanical or electronic). Their differences in operation and design clearly indicate that their applications are different. The latter aims to protect end-user equipment from overpressure and undervoltage conditions. However, this article will focus on high voltage automatic load modulators, and voltage applications are mainly used to compensate for voltage drop in feeder or power distribution systems.

An instantly acting automatic voltage booster

An instantly acting automatic voltage booster employing autotransformers each having a secondary winding connecting between power supply lines and a load in a three phase system for supplying power continuously to the load. Primary windings are maintained in short circuited condition by contacts of a relay actuated when step voltage regulators supplied via the supply lines remains above a predetermined minimum magnitude. The relay contacts open to energize the primary windings and induce voltage in the secondary windings when the supplied voltage falls to or below the predetermined magnitude for maintaining voltage supplied to the load above the predetermined magnitude. A switch is provided to short circuit the secondary windings and open circuit the primary windings in the event of equipment failure.
