Excitation Control System (AVR system)

Excitation Control System (AVR system)

The excitation control system automatically controls the generator terminal voltage by supplying DC current to the generator's field winding
By controlling the DC current according to the system load, it supplies the high-quality electricity that customers want.
It is equipped with a power system stabilization system (PSS), contributing to system stability.
The excitation system is applied to thermal, pumping, hydropower, combined and nuclear generators and is designated as a major facility.
