Basler Electric DGC-2020HD Digital Genset Controller
Description
A rugged paralleling and load-share controller for multi-set plants
The Basler Electric DGC-2020HD is a rugged, reliable, all-in-one genset control and load share system. Basler designed it as a complete, adaptive controller for mains fail, paralleled units and systems with multiple buses, with the necessary control, protection and metering plus an extensive programmable logic system.
It can monitor a generator and up to two buses using up to seven current transformers, handles kW and kvar load sharing over Ethernet, and offers peak-shave and import/export power control. The housing is potted for extreme environments, with an IP56 front panel.
DGC-2020HD functions
- Three-phase generator metering; up to two buses with three-phase voltage metering
- Three dedicated generator CTs plus up to four auxiliary CTs
- Standard protection 27, 59, 81O/U, 32, 40Q; enhanced 46, 47, 51, 78, 81 ROCOF; Enhanced Plus option adds 87N and 87G differential
- Load sharing of kW and kvar over Ethernet; soft loading and unloading with zero-power transfer
- Peak Shave and Import/Export modes, load anticipation, automatic load shedding, tie breaker control
- Dual CAN ports (J1939 ECU and expansion), dual Ethernet ports (fibre optional), optional colour touch screen
- Connects to four AEM-2020, six CEM-2020 modules and one VRM-2020 voltage regulation module

DGC-2020HD or a simpler controller?
Choose the HD when sets must share load, close to more than one bus or run in peak-shave and import/export schemes. For a single standby set the DGC-2020 or DGC-2020ES covers the need at lower complexity. Decide on the standard, enhanced or Enhanced Plus differential protection, the colour touch screen, fibre Ethernet and analog sender options at order stage, using the datasheet style chart; supply the style code, bus layout and breaker scheme so we can check the selection.
Installation and operation notes
Breaker schemes are selected in BESTlogicPlus, which makes breaker control quick to configure; the built-in real-time monitor helps during commissioning and tuning. Plan the CAN network carefully, because one CAN port serves the J1939 engine ECU and the other serves expansion modules. Segmented-system and tie-breaker (Main-Tie-Main) control modes are described in the datasheet and should be validated with the system integrator.
Where the DGC-2020HD is used
Multi-engine power stations, camp power plants and industrial sites with paralleled sets, mains-fail systems with a tie breaker, and plants with peak-shave contracts. The potted, IP56 front-panel design and the -40 C to 70 C operating range (default screen) are intended for the harshest panels.
Selection and care notes
Paralleling systems depend on correct wiring and settings, so confirm the number of generators, the bus arrangement, the communication network and the load sharing method before ordering. Commission with the software, test the logic offline where possible and save the settings. Check the potting and the IP56 front panel against the installation conditions.
