Natural gas generator set QSK60 series engine - 1

Specification sheet Natural gas generator set QSK60 series engine 995 kW - 1540 kW Description This Cummins® gas generator set is a fully integrated power generation system utilizing state of the art technology that results in optimum performance and efficient use of fuel for continuous duty, CHP and peaking applications. Features Exhaust emissions – Lean burn technology provides exhaust emissions levels as low as 250 mg/Nm3 (0.5 g/hp-hr) NOx. Cummins® high efficiency gas engine – State of the art lean burn engine utilizes Miller cycle combustion and full authority electronic engine management system that provides low emissions and high efficiency. Permanent magnet generator (PMG) – Excitation system offers enhanced motor starting and fault clearing short circuit capability. Alternator – Several alternator sizes offer selectable voltage and temperature rise with low reactance 2/3 pitch windings; low waveform distortion with non-linear loads, fault clearing short circuit capability, bearing and stator RTDs, anticondensation heater, class F or H insulation (see alternator datasheet for details). Mechanically strengthened for use on utility paralleling with unreliable grid. Control system – The PowerCommand 3.3 generator set control is standard equipment and provides total generator set system integration including full paralleling capability in grid or load share mode, precise frequency and voltage regulation, alarm and status message display, AmpSentry™ protection, output metering, autoshutdown at fault detection and a user interface panel installed onto the generator set. Optional grid code compliant controls systems and operator panels are also available. Cooling system – The generator set is equipped with the capability to interface with a remote radiator or heat exchanger. Warranty and service – Backed by a comprehensive warranty and worldwide distributor network that can provide all levels of service from replacement parts to performance guarantee programs. 50 Hz 60 Hz Model kW Configuration Model kW Configuration C995 N5C 995 4 pole direct drive C1200 N5C 1200 4 pole direct drive C1400 N5C 1400 4 pole direct drive C1000 N6C 1000 6 pole direct drive C1540 N5CC 1540 4 pole direct drive C1100 N6C 1100 6 pole direct drive * Genset is capable of operating between 0.8 lagging and 1.0 power factor unless specified otherwise.
