Description
Base Bid Scope Of Supply
Titan 130 power generator set basic package
The Titan 130 power generator is a compact gas turbine designed for power generation applications
The generator set is a completely integrated package ready for installation
The gas turbine engine, gearbox, generator, control system, fuel system, lubrication system, and start system are included in the package
Package certification: Solar is supplying a CSA certified NEC package; no modifications are included to comply with GOST or other Russian or European standards
Base: the turbine and the generator assemblies are each installed on a separate base frame platform that provides rigid support for the driver and driven equipment
Each base provides a permanent mounting structure for the associated operating systems and accessories
The bases are manufactured by Solar using structural steel with welds per AWS D1.1
Four lifting eyes are welded to each base
Drip pans to collect potential liquid spills are welded within each base
Approximate overall dimensions: 46 ft (14.02 m) long, 10 ft - 10 in (3.30 m) wide
Approximate height of an unenclosed package is 10 ft - 9 in (3.28 m) and may vary with ancillary equipment and generator selection
Piping: all tubing and piping with a nominal diameter up to 4 inches are made of stainless steel
Package piping is designed and fabricated to ANSI B31.3
Tube fittings: all tube connections use stainless steel compression fittings
Electrical system: the PG generator set is designed to comply with the requirements of the National Electrical Code for installation in a non-hazardous location per NFPA 37
Package motors and heaters are rated for 380 VAC / 50 Hz / 3-phase, unless otherwise noted
Single-phase loads are rated for 220 VAC / 50-60 Hz, unless otherwise noted
Gas Turbine Engine
The Solonox Titan 130S is a single shaft, axial flow gas turbine engine that includes Solar's dry, low NOx combustion system
The output gearbox, including accessory drive pads, is a separate, close-coupled unit located at the forward end or turbine air inlet side of the package
The engine assembly consists of: gear unit with accessory drive pads; air inlet collector with a flexible flange connection; axially split compressor case in the vertical plane, housing a fourteen-stage axial flow compressor with variable geometry consisting of variable inlet guide vanes control over the first six rows of stators; annular Solonox combustor with 14 lean premix fuel injectors; three-stage power turbine assembly; turbine exhaust collector
The components of the Solonox Titan 130S engine are maintained in accurate alignment by mating flanges and are bolted together to form a rigid assembly
The turbine rotor shaft drives the speed-reducing gearbox
The gearbox mechanically drives the main lube oil pump
The gas turbine output shaft is mechanically coupled to both the compressor and turbine sections of the engine to form a solid or single shaft configuration
This feature enhances speed stability and response under constant and varying load conditions - a highly desirable feature in generator applications requiring precise frequency control
Inlet orientation: the gas turbine air inlet flange terminates in the up position
Speed-Reducing Gearbox
The reduction drive gearbox is provided to reduce the output speed of the turbine to the generator's required input speed of 1500 rpm for 50 Hz applications
The speed-reducing gearbox contains an epicyclic star-compound gear designed specifically for the PG turbine-generator set
The gearbox is bolted directly to the gas turbine engine to provide a rigid support; therefore gearbox alignment with the engine is not required
Alignment tooling is provided to align the reduction gearbox output shaft with the generator input shaft
Generator
Generator rating: the generator is rated per NEMA standards so that it will not limit turbine performance over the Solar specified range of site ambient temperatures
Generator standard features include: sleeve bearings with pressure fed sumps; stator winding RTD's; power terminal box; form wound stator windings; rotor balance to 125% rated speed; permanent magnet pilot exciter; anti-condensation space heaters; 300% short circuit capability for 10 seconds; overload capacity per NEMA (continuous duty rating): 150% rated current for 1 minute, 110% for 2 hours in any 24-hour period
Voltage regulator characteristics: solid state; three-phase sensing (single phase sensing can be accommodated); ±10% voltage adjustment range, voltage resolution is 0.1%; ±0.50% steady state voltage regulation; reactive load sharing to within 5% nameplate rating; crosscurrent compensation capability
Voltage drift: the change in voltage will not exceed ±1.0% when the generator is operating at rated voltage, 0.8 to 1.0 lagging power factor, and with a constant load between no load and full rated load
Generator construction: an open drip proof generator per NEMA standards is provided
Generator voltage: the generator output is 10,500 volt / 50 Hz / 3-phase
Insulation conforms to NEMA class F with class B (80°C) temperature rise
Start System
Start motor: two direct drive AC electric motors are provided to start the gas turbine engine
A blank plate is located at the package base edge for routing cables or conduits for electrical interconnection to the start motor inside the package
Variable frequency drive: a single variable frequency drive (VFD) is provided to control the speed of the two AC start motors
The VFD is housed in a NEMA cabinet, designed for wall mounting installation off-skid in a non-hazardous
Natural Gas Fuel System
A natural gas fuel system is provided and includes all the hardware and software components necessary to maintain turbine speed and provide a constant generator output frequency and/or load depending on the generator set mode of operation
The fuel system, in conjunction with the electrical control system, includes all necessary components to control the fuel pressure, schedule fuel flow during start-up, and modulate fuel flow during operation
The fuel system also provides the necessary instrumentation for the control system to monitor the operation and automatic shutdown of the unit in the event of a malfunction
Pilot system: the pilot system is a fail-safe fuel shutoff system in the event of a control system failure
The fuel pilot system requires external compressed air to the customer connection located on the side of the package base; reference the package utility requirements list for air flow and pressure requirements
Fuel requirements: the natural gas fuel system requires a constant supply of fuel to the customer connection located at the side of the package base
The fuel quality must conform to Solar specification ES 9-98
The gas fuel should be free of sulfur, contaminants, entrained water, and liquid hydrocarbons; please also refer to Solar's product information letter (PIL) 162: recommendations for the sourcing, handling, storage, and treatment of fuels for Solar gas turbines
