2       Design Principles / Scope of Supply
2.1  Design Principles
Generator use gas fuel as power supply and thermal dynamic conversion from spark ignition engine. Equipped with cooling,lubrication,fuel supply,control,power output,parallel gensets,base frame system which is a completed power output equipment. Low voltage,high pressure gas fuel is acceptable.
Gas engine and flange-mounted alternator (SAE  housing) are connected via a torsionally resilient coupling and resiliently mounted to a rigid, welded steel base frame. Between them there is vibration dampers for eliminating vibration.
Genset controllers integrated on the base frame,adopting DeepSea or ComAp generator set controlling module
Gas valves integrated on the base frame,gas valves including:pressure gage ,filter,pressure maintaining valve,safe solenoid,flame arrestor
Gas Engine:Cummins NTAA855 engine,equipped with multi-sequential ignition engine management control system,one high energy ignition coin per cylinder,gas dedicated speed governor (WOODWARD),proportional gas mixer,exhaust gas turbocharge,air/air intercooler
Alternator:Marathon/USA  brushless self excitation AC synchronism alternator with PMG function
Skid Mounted Generator Set
