Technical Specifications of 1600kva Cummins Diesel Genset

1600kva/1280kw Prime rated emergency diesel generator is manufactured by Dingbo Power factory, it is powered by CCEC Cummins engine KTA50-GS8, coupling with original Stamford S7L1D-D41 and Deep Sea controller 7320MKII, mounted on a steel frame structure with skids and necessary dampers and floor anchors. The genset is installed in a canopy container cabinet for outside any building, soundproof and weatherproof.

Dingbo Power includes all the equipment and components necessary to complete the set as a fully operational unit namely control cabinet, electric starter, battery, charger exhaust system, fuel day tank, cables, piping, etc. All mechanical and electrical accessories is mounted on the generator set. The exhaust pipe and muffler is extend outside the generator container. Of course, the exhaust and muffler also can inside the generator container.

This 1600kva Cummins diesel generator meets the standard of ISO9001 quality management system certifications.

2.Generator Set Performance

Voltage

Automatic voltage regulator is solid state hermetically sealed for moisture protection.

It is three phases, sensing, filtered, with Volt per Hertz regulation and with improved transient response capability.

Voltage regulation: ±1% steady state from no load to full load including variation of power factor 0.8 to 1 and speed variation of 5%.

Voltage adjustment: ±10%

Waveform distortion: Total harmonic distortion with 30% asymmetric load shall be less than 5%.

Short circuit current capability:

300% of rated current for 5 seconds. If necessary Permanent Magnet Pilot exciter can be supplied.

Governor

Governor is electronic type.

Frequency performance: 50Hz

Even that the system will work as a stand alone system (not synchronized to another source) the governor and control system will be suitable to be synchronized to another source.
