DUOGEN
Two gensets controlled
by a single unit

• Cost effective solution
• Manual and auto synchronization
• Load sharing (kW/kVAR)
• 50 / 60 Hz compatibility
• Fast commissioning

DUOGEN is a microprocessor ONE UNIT – TWO GENSETS
based module which controls DUOGEN is a cost effective and innovative unit for synchronization and
load sharing with 2 gensets. It combines the following features:
two generators.
DUOGEN carries out manual
and auto synchronization, isochronous load sharing or droop
load sharing.

•t 1 digital input for auto synchronization.
•t 1 sync check relay to monitor phase, frequency and voltage differences.
•t 1 ‘Load shedding’ output relay which start/stop the generators
depending on power requirements. This allows a better power plant
global efficiency.
•t 2 isochronous kW sharing controls.
•t 2 constant voltage kVAR sharing controls.
•t 2 reverse power protections.

INPUTS/OUTPUTS FOR EACH GENSET

•t 3 phase genset voltages (3 or 4 wires, 100 to 440 VAC).
•t 3 phase genset currents (1A or 5A CTs).
•t 1 digital input: feedback of the genset breaker position.
•t 1 digital input: unload request (adjustable ramp time).
•t 1 analog input for speed control (potentiometer ± 5 VDC).
•t 2 output relays: breaker trip and reverse power protection.
•t 1 analog output: active power monitor (0-5V or 0-1mA adjustable).
•t Proportional and integral gain potentiometers for synchronization.
•t 1 analog output for speed control which is adjustable with Gain
and offset potentiometers, compatible with most electronic governors (Barber Colman, Woodward, GAC, Heinzmann, Ambac, DDEC,
MDEC…).
•t 1 analog output for voltage control, adjustable with Gain and Offset
potentiometers, compatible with most AVRs (Leroy Somer, Stamford,
Basler…).
