Automatic genset controller AGC-4

The Automatic Genset Controller, AGC, is a flexible control unit containing all necessary functions for protection and control of a genset. It can be used as a single unit for one genset, or a number of AGCs can be connected in a complete power management system for synchronising projects, islanded or paralleled to the mains.

Patent-pending Emulation

A standard in the Automatic Genset Controller, AGC-4, using DEIF’s Emulation Solution, all you need to do to perform a complete test of your Power Management Systems is to turn on your controller and connect communications.

Remote communication and control

The AGC-4 supports serial communication protocols including Modbus (RS-485, USB, and TCP/IP) and Profibus. This feature allows you to supervise and control your genset/plant from a remote location. 

Critical power applications

With its integrated close before excitation (run-up synchronisation) feature, the AGC-4 secures backup power availability from an impressive six seconds. Combined with the option of having doubled, redundant/hot standby controllers on all positions, the unit is ideal for all types of critical power applications, such as data centres, hospitals, airports and fish farms. 

Rental genset applications

Rental companies will benefit from the standardised user interfaces of all DEIF controllers. The controllers have been designed with ease of operation in view, and rental companies can easily set and lock parameters to ensure full protection of their equipment.

Hybrid applications

AGC-4 is plug’n’play compatible with DEIF’s ASC-4 hybrid controller for easy integration of diesel genset applications into a variety of hybrid installations. The market-leading solution maximises sustainable power penetration while always securing a sufficient amount of spinnning reserve in case PV production drops.

Available standard modes:

Island mode: Power plant with synchronising generators or a stand-alone generator. Also applicable in critical power plants.

Automatic Mains Failure: Critical power/emergency standby plants, black start generator.

Fixed power: Power plant with fixed kW set point (including building load).

Peak shaving: Power plant where generator supplies peak load demand paralleled to the mains.

Load takeover: Plant mode where the load is moved from mains to generator, for example peak demand periods or periods with risk of power outages.

Mains power export: Power plant with fixed kW set point (excluding building load).

Remote maintenance: Used when the generator has to supply the load while a distribution transformer is disconnected for service.

All modes are configurable, and it is possible to change the plant mode on the fly both in single and in power management applications.

Grid code compliant

The AGC-4 controller complies with the majority of requirements for parallel to grid operation, including VDE, EN and ENA standards. Both protections and grid support functions are included, giving you a “single controller fits all” solution.
