Aplicații
Rezidential/ComercialUn Grup Electrogen lucreaza adesea cu o sarcina medie foarte scazuta, in special cind este utilizat impreuna cu un sistem de producere a energiei din surse regenerabile (solara, eoliana, etc) Aceste circumstante cresc consumul de carburant si diminueaza intervalele de intretinere datorita, printre altele, reziduurilor mari de combustie.
Grupurile Electrogene COELMO® din seria DCi Generators cu turatie variabila sunt proiectate si realizate pentru a rezolva problemele de joasa eficienta si de intretinere ridicata.
Datorita unui alternator cu magneti permanenti, un sistem electronic de gestiune si un convertor AC/DC, Grupul Electrogen COELMO® DCi Generator lucreaza intotdeauna intr-un regim de turatie care optimizeaza eficienta sistemului, maximizind perioada dintre intervalele de intretinere si reducind zgomotul, cu tensiunea stabila si un riplu scazut la iesire
Grupurile Electrogene COELMO® din seria DCi Generators cu turatie variabila sunt re comandate pentru acele aplicatii unde puterea e sensibil mare in raport cu sarcina medie ajungindu-se la o economie de combustibil si intretinere de aproximativ 40% comparativ cu un grup electrogen traditional.

Nowadays, most of the telecoms equipments are designed to run on DC power. If an AC Generating Set is installed, a DC rectifier is required, with a lose of almost 5-10% in efficiency. DC rectifiers are also a common point of equipment failure on telecoms site.
By using a DC Generating Set in a Hybrid System, no rectifier are required, resulting in:
- Better power efficiency = lower fuel usage
- Less equipment heat = less site cooling = lower fuel usage
- Less maintenance = lower maintenance costs
An addition benefit of a DC Generating Set based Hybrid System is that no separate battery charger is required, since the Generating Set can charge the battery bank directly.
A Variable Speed Generating Set is a Generating Set that is able to regulate the power based on the site load.
Despite the traditional Generating Sets, that can only operate at a standard rotation (3000/1500 rpm @ 50Hz or 3600/1800 rpm @ 60Hz) delivering the rated power only, a Variable Speed Generating Set, equipped with a permanent magnet generator (PMG) and an electronic management, is designed to deliver the exact power required by the site, following the load variation, maximizing the intervals maintenance and reducing the noise , with a stable voltage and a low output ripple.
By using a Variable Speed Generating Sets the following benefits are found:
- Better power efficiency = lower fuel usage
- Less maintenance = lower maintenance costs
- Extended Engine Life Time
Benefits of Hybrid Systems with DC Variable Speed Generating Set:
- Fuel Saving of up to 85%
- Maintenance cost reductions of up to 75%
- Extended Generating Set lifetime of up to 300%
Reduced equipment requirements:
- No rectifier required
- Possible removal of air conditioning supported through removal of rectifier heat
- Replacement of UPS battery bank with deep-cycle battery bank.
