Automatic Voltage Regulator Design for a Synchronous Generator

Synchronous Generator or alternator is the most prevalent and important component in a power system.  Most types of generating stations working as base load power plants use this type of generator to generate electrical power. It is requirement from all types of generating plants to provide an electric supply which has excellent voltage regulation. Due to this constraint it is essential to ensure a nearly constant voltage profile at the terminals of synchronous generator under all load conditions.

The objective of this project is to design an automatic voltage regulator for a synchronous generator, which controls the terminal voltage automatically by varying the excitation voltage of the generator in response to change in terminal voltage.
