KDR-1100,1200 (Excitation Control System)

KDR-1200S/1200D (Excitation Control System)

Collaborative product of E2S and KEPRI

A generator auto voltage controller(KDR-1100,1200D) is sometimes called an excitation system.
It controls the DC current flowing in the field winding of a synchronous power generator in order to adjust the output voltage of a generator.
It improves the electricity quality and stabilizes the power system.

TriEx (Tripe Redundant Excitation System)

Collaborative product of E2S and Doosan heavy industry

Various control functions of a generator excitation system are backed up by the
limit/protection functions. Such control and protection functions tend to become digitalized. To improve the reliability, we prefer to make dual/triple structure of these controllers. TriEx is a device developed jointly with Doosan Heavy Industry to perform a triple function of a digital excitation controller.
