1407-CGCM/C

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.
Functions The following sections outline the functions of the unit. Generator Regulation and Control Functions
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
