Generator Excitation System & Voltage Regulator (AVR)

Excitation systems are fundamental to the operation of modern synchronous machines. It is responsible for supplying direct current for the synchronous machine field windings. Well-designed excitation systems provide reliability of operation, stability and fast transient response.

  • For synchronous generators, it is responsible for maintaining a constant terminal voltage.
  • For synchronous motors, it is responsible for maintaining a constant power factor.

Excitation systems use closed-loop or feedback control to regulate the machine’s output. It also works as a Limiter – Limit the synchronous machine to work within the boundary & capacity. In addition, modern excitation system that equipped with the Power System Stabilizer (PSS) function,  provides a positive contribution by dampening the electromechanical oscillations arisen from the power system or the unit itself.
