Auto voltage control device

KDR-1100,1200 (Excitation Control System) KDR-1200S/1200D (Excitation Control System)

Collaborative product of E2S and KEPRI

A generator auto voltage controller(1200S/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.

Features
1. Digital control + analog backup(KDR-1200S)
2. Dual digital control(KDR-1200D)
3. Auto voltage controller(AVR), manual voltage controller(MVR)x
4. Overexcitation limiter(OEL)m under excitation limiter(UEL)
5. Over field flux limits(V/Hz)
