intro

The combined generator control module (CGCM unit) is a microprocessor based control and protection device.

CGCM units can be integrated with Logix series programmable controllers to provide generator control, protection and synchronization.

With programmability of system parameters, adjustment Settings and protection functions, CGCM units can be used in a wide range of applications.

Feature

The following sections outline the capabilities of the device.

Generator regulation and control functions

This list includes 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 increase via adjustable ramp in AVR and FCR control modes

- Limit overexcitation (OEL) and underexcitation (UEL) in AVR, VAR and PF control modes

- Underfrequency compensation (volts/Hertz)

- Line drop compensation

- Automatic tracking between running modes and between redundant CGCM units

- Automatic transfer to standby CGCM units in redundant systems

- Parallel generators with reactive drop compensation or cross current (reactive differential) compensation

- Generators in parallel with actual power load sharing

- One or two circuit breakers are synchronized
