A-B 1407-CGCM C

Description

ALLEN BRADLEY 1407-CGCM is a combined generator control module produced by Allen-Bradley(a brand of Rockwell Automation).The following is a detailed introduction to the product:

1.Product Overview

ALLEN BRADLEY 1407-CGCM is a microprocessor-based control and protection device that integrates the regulation,protection and synchronization functions of the generator.It supports multiple control modes for different application scenarios and provides a wealth of input and output options,including communication interfaces and excitation power connections,for easy integration and flexible application.

2.Main functions

Generator regulation and control functions:

Four excitation control modes:automatic voltage regulation(AVR),manual or field current regulation(FCR),power factor(PF)and reactive power(VAR).

In AVR and FCR control modes,soft start voltage increase is achieved through adjustable ramps.

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

Underfrequency compensation(volts/hertz),line drop compensation.

Automatic tracking between operating modes and between redundant CGCM units.

Automatic transfer to standby CGCM unit in redundant systems.

Generator paralleling with reactive droop compensation or cross current(reactive differential)compensation.

Generator paralleling with real power load sharing.
