)NTRODUCTION

The Combination Generator Control Module (CGCM unit) is a

microprocessor-based control and protection device. The CGCM unit is

designed to integrate with a Logix family programmable controller to provide

generator control, protection and synchronization functions. Programmability of

system parameters, regulation settings, and protective functions enable the

CGCM unit to be used in a wide range of applications.

&UNCTIONS

The following sections outline the functions of the unit.

'ENERATOR2EGULATIONAND#ONTROL&UNCTIONS

This list contains the generator regulation and control functions:

•Four excitation control modes

•Automatic voltage regulation (AVR)

•Manual or field current regulation (FCR)

•Power factor (PF)

•Reactive power (VAR)

•Soft start voltage buildup with an adjustable ramp in AVR and FCR

control modes

•Over-excitation (OEL) and under-excitation (UEL) limiting in AVR,

VAR, and PF control modes

•Under-frequency compensation (Volts/Hertz)

•Line drop compensation

•Auto-tracking between operating modes and between redundant CGCM

units

•Automatic transfer to a back-up CGCM unit in redundant systems

•Generator paralleling with reactive droop compensation or cross-current

(reactive differential) compensation

•Generator paralleling with real power load sharing

•Synchronizing for one or two circuit breakers
