Danvest - Low-Loading Diesel Generator
Danvest enables conventional gensets to operate below 30% load at low fuel consumption, while keeping the ability to respond fast to any load changes. The gensets are ‘grid-forming’ at all times.
Robust Power Supply
- Excellent 50 Hz or 60 Hz power quality (+/- 0.5 Hz)
- The genset is grid-forming from zero to full load, always providing voltage and frequency control
- Non-stop available dynamic reactive power
- Using A-brand gensets – Factory warranties apply
- Only requires normal diesel service
- Easy to operate
High Direct Fuel Savings
- Annual fuel savings are 50-70% with wind turbines and 30-40% with solar systems (24/7 demand)
- Any renewable energy source is applicable
- With Danvest it makes sense to install renewable capacity that can match ‘peak demand’
- Payback period for total plant is 3 to 6 years
- Energy storage systems are optional
- Danvest components will be added to a conventional high speed genset.
- All factory warranties apply as the engine remains untouched.
- A Danvest genset operates like any other diesel generator.
Using standard components
THE ‘DEMS’
The ‘Danvest Energy Management System’ enables the genset to operate effectively under the 30% load at low fuel consumption. The system is grid-forming at all times, even when the engine clutches out, never losing frequency and voltage control.
MAGNETIC CLUTCH (optional)
The engine can de-clutch and stop when surplus renewable energy hits a set-point. The alternator continues to rotate at a constant speed and remains connected to the busbar. When the engine has to restart, it starts fast as it is disconnected, pre-heated and pre-pressurized.
PRE-PRESSURE SYSTEM
The pre-pressure system blows heated air in the air receiver when Danvest is in low-load operation. It avoids engine oil to loop up and it enables a better and cleaner combustion.
PRE-HEATER SYSTEM
The pre-heater system cooperates with the radiator system to heat up the engine cooling water when Danvest is in low-load operation. Avoiding cooling down of the engine enables a better and cleaner combustion.
DUMP LOAD CONTROLLER
A reliable dump load controller assists during fast load variations and when in low-load operation. It secures a balance between fluctuating energy supply and energy demand. The straightforward dump load system can optionally be replaced by a battery pack.
There is no technical reason to add a storage system to Danvest. Adding an ESS can purely be seen on its own economical and practical merits.
A precondition, is that renewable energy surpluses should appear on a regular base.
But these surpluses can sometimes also be allocated to energy off-takers like heaters, water pumps, TES systems, electric vehicles etc.
But…
- Any added storage capacity will add straight to the direct fuel savings of Danvest
- Hybrid inverters will not be necessary as Danvest always forms the grid.
- The amount of cycles and wear and tear of an ESS will be minimal.
- Top-tier genset brands will be Danvest-equipped in our workshop in The Netherlands.
- All Danvest products are thoroughly FAT-tested before shipment.
- We offer systems from 200 to 2.000 kW on one skid.
The high speed (1.500 rpm / 1.800 rpm) gensets keep their original factory given performance specifications and warranties
- The running conditions are centrally monitored via a regular SCADA connection
- The DEMS can be updated via SCADA
- We offer all kind of canopy/ container housings to suit local (climate) conditions
- The magnetic clutch can be opted-out at smaller capacities
- Waste-heat recovery systems are possible additions
- 24/7 worldwide service
When necessary we will send someone of our dedicated team or we use the service of available global diesel service networks. We know better than anyone else what the condition is of your Danvest genset. And when treated well, Danvest systems will last forever!
