1. SCOPE OF SUPPLY
1.1 Basic Scope Description
1.a.1 Gas Turbine
It is a 3 spool, hybrid gas turbine, consisting of a low-pressure compressor (LPC). LPC (first six stages) for higher airflow capability, an aero derivative core (consisting of a high-pressure compressor, combustor and high pressure turbine), a new two stage intermediate pressure turbine (IPT) which drives the LPC, and a new 5-stage free power turbine (PT), with the output shaft located aft of the free power turbine (hot end drive). Performance is normally 100 MW with >46 % simple cycle thermal efficiency. The distinguishing element is the intercooler, which is located between the LPC and the high-pressure compressor (HPC). lntercooling reduces HPC work of compression for increased efficiency and increases mass flow capability in the same turbine for increased power.
The equipment package is supplied with an air cooled, 2-pole, 13.8 kv V (60 Hz) generator located outside of the turbine enclosure and capable of handling the power requirement over a wide ambient temperature range. Fans, mounted on each end of the generator rotor shaft inboard of the bearings, draw air through the generator filter assembly. The cool air is forced through the air gap between the rotors and the stators in the main and exciter housings. The warm air is discharged through the top of the generator housing, directing warm exhaust air back to the air inlet to ensure ice does not collect on the inlet filter. The generator includes a brushless excitation system with a permanent magnet generator, along with neutral and line side cubicles.
1.a.3 Turbine Baseplate
The equipment package is supplied with the support structure for the gas turbine. Full depth cross-rnembers are utilized to provide for a rigid design that is suitable for installation in earthquake areas (IBC 2000) as well as providing a convenient structure for transportation.
The equipment package is supplied with an intercooler system that includes a water cooled heat exchanger, variable bleed valve (VBV), VBV silencer, and interconnect piping and supports. Customer must supply the necessary cooling water from a cooling tower or other source.
1.a.5 Unit Handing and Lineside Cubicle Configuration
In the standard configuration, as viewed from the generator non-driven end, the intercooler is located on the left side of the unit and the engine exhaust is located on the right.
The generator lineside termination cubicle is on the left side and the neutral cubicle is on the right. The generator lineside cubicle is configured for top bus duct entry.
1.a.6 Electro-Hydraulic Start System
The equipment package is supplied with an electric motor driven hydraulic pump assembly, filters, cooler and controls, mounted on the auxiliary equipment module. A hydraulic motor is also mounted on the accessory gearbox. Hydraulic hoses are furnished to connect the auxiliary equipment module and the main baseplate. The standard start cycle is 10 minutes to full load for non-DLE, non-steam injected units utilizing simple cycle exhaust stacks.
1.a.7 Fire Protection System
The equipment package is supplied with a factory installed fire protection system complete with optical flame detection, hydrocarbon sensing and thermal detectors, piping and nozzles in the engine compartment. The fire protection system includes cylinders containing CO2 mounted on a separate module. A 24 V DC battery and charger to power the fire protection system is also included. All alarms and shutdowns are annunciated at the unit control panel. An alarm sounds at the turbine if the gas detectors detect high gas levels, or if the system is preparing to release the CO2. When the system is activated, the package shuts down, the ventilation dampers automatically close, and the CO2 cylinders are discharged into the turbine compartments via multiple nozzles. Auxiliary enclosures, if provided, are equipped with hand held extinguishers.
1.a.8 Battery System
The equipment package is supplied with 24 V DC battery systems for the fire protection and gas turbine generator control systems, as described in those sections. The package is also supplied with o 125 V DC battery system for control cooling backup and a 240 V DC battery system to power the mineral lube oil system DC motor driven backup pump. All battery systems are valve-regulated lead acid (VLRA) type. Battery systems ship loose for indoor customer installation. If the optional Power Control Module is selected,the supplier will install the supplied DC battery systems in that module.
1.a.9 Generator Protective Relays
The equipment package is supplied with a microprocessor-based generator protective relay module, mounted in the turbine control panel. Protective relay system includes functions necessary for protection of the generator.
1.a.10 "On/Off Line" Cleaning and Soak Wash System
The equipment package is supplied with an "on-line" cleaning system, which allows customers to clean the compressor section of the engine during full power operation The same system reservoir and piping are utilized for off-line soak washing. Customer is required to provide purified water meeting MlD-TD-0000-4 and detergent meeting MID-TD-0000-5.
1.a.11 Component Testing and Factory Test for Package
The generator is tested to ANSI C50.14 or IEC 34.3 standards at its factory of manufacture. The core gas turbine (minus LPC, IPT, and PT) is performance tested at a test facility.The standard factory test for the package is a rigorous static test to confirm:
A full speed no load string test is available as an option.
