double helical precision carburized ground gear elements, split steel backed babbitt lined journal
bearings on all shafts and a low speed quill shaft.
Unit Enclosure
The equipment package is supplied with weatherproof acoustic enclosures. The enclosures are
completely assembled and mounted over the equipment prior to testing and shipment. The gas
turbine compartment is fully ventilated with duplex belt driven fans. The generator compartment is
fully ventilated with direct driven fans. Explosion-proof A.C. lighting is provided in both
compartments. The enclosure provides guaranteed average noise emission of 85 dB(A) at 1m
distance measured at 1.5m above grade in a free field condition, during full load operation. Noise
emission could be greater than 85 dB(A) at 1m distance measured at 1.5m above grade in a free
field condition, during equipment start-up and shut down.
Baseplate
The equipment package is supplied with the support structures for the gas turbine generator set
consisting of a two piece skid assembly, which is sectioned between the gas turbine and the
generator/main load gearbox. The full depth, bolted section is designed to provide the full structural
properties of the wide flange I-beams. Full depth crossmembers are utilized to provide for a rigid
design that is suitable for installation in earthquake areas (U.S. Seismic Zone 4) as well as
providing a convenient structure for transportation. The baseplate support system is enhanced by
the installation of a heavy duty, welded superstructure which utilize structural tubing for wall
columns and roof beams.
Air Inlet System
The equipment package is supplied with a modular, three-stage filtration system consisting of inlet
screens, an EU4prefilter and an EU7 final barrier filter.
The filtration system removes more than 99.9 percent of all particles 5.0 micron and larger by
utilizing a three-stage design, that is designed to meet the following downstream conditions:
~95% of the time, must not contain solid particles exceeding 0.004 grains/1000 cubic feet, and
~5% of the time, must not contain solid particles exceeding 0.04 grains/1000 cubic feet.
It will be possible to replace the pre-filter and high efficiency filter without stopping the GTG,
however, replacement of the high efficiency filter with the GTG on line is very dangerous and not
recommended by GE Energy.
Acoustical louvers for noise control are installed to the intake of the inlet filter, in lieu of the weather
hoods. The acoustic louvers provided are 600 mm deep. The acoustical louvers provides
guaranteed average noise emission of 82 dB(A) at 1m distance from the inlet filter intake, during full
load operation. The estimated pressure loss added by the louvers is 20 mmH2O. A detailed
description of the acoustical louvers provided for noise control and installed to the intake of the inlet
filter is included in Section 7 of this proposal.
All air for ventilation systems is filtered to the same level as turbine combustion air.
Filtered air is silenced before entering the turbine plenum. This design results in a compact
arrangement and eliminates the need for customer supplied inlet ducting when the standard design
is utilized. Internal lighting of the filter house is provided to facilitate inspection and service.
Package is also supplied with platforms and ladders to service the inlet filter (internal platforms and
ladders only). These items are packaged separately for shipment.
Inlet Air Multi Purpose Coils
The equipment package is supplied with high performance multi purpose coils for combustion air
heating and chilling as an integral part of the air inlet system. Customer shall provide adequate
quantities of hot water and chilled water and interconnecting piping to GE Energy furnished chilling
coils at filter house.
For the Anti-Ice System, that is required to allow safe operation of the equipment package during
icing conditions, Customer shall furnish water at 27°C and 345 kPag, for circulation through the GE
Energy supplied coils. The quantity of heat should be enough to heat the inlet air 5.6°C above
ambient temperature when ambient temperatures are less than -1.1°C and to heat the inlet air to
4.4°C when ambient temperatures are between -1.1 and 4.4°C . No heating is required for
ambient temperatures above 4.4°C .
For temperatures below -9.4°C there is no need for anti-icing operation, due to the very low
moisture content of the air. The only expectation would be where there is fog, snow, or other visible
precipitation.
Anti-ice protection is not required during startup and warm up period (maximum 5 MW) for up to 1
hour maximum time period.
Turbine Exhaust
The equipment package is supplied with a circular, axial exhaust outlet with connection flange to
facilitate in-line mounting of a WHRU.
Fuel System
The equipment package is supplied with a Dry Low Emission (DLE) natural gas fuel system using
an electronically controlled fuel metering valve. All necessary shutoff valves, piping and
instruments between the fuel module connection and the engine are included. As part of the fuel
system, a fuel gas chromatograph for engine control purpose is also provided as a loose item.
SPRINT® (Spray Inter-cooling) Power Boost System
The equipment package is supplied with the SPRINT® boosts system for engine performance
augmentation. The SPRINT® boosts engine performance system uses a spray inter-cooling design
that significantly increases the mass flow by cooling the air during the compression process. The
system is based on an atomized water spray injected through spray nozzles placed at two
locations, one between the high pressure and low pressure compressors, and the second at inlet
bellmouth. Water is atomized using high pressure air taken off of the eighth stage bleed. The
water flow rate is metered, using the appropriate engine control schedules and at the inlet
bellmouth. Bellmouth and inter-stage portions on SPRINT® alternate operation based on turbine
inlet temperature.
If the SPRINT® boosts system is used, Customer must provide a supply of purified water per GE
specification MID-TD-0000-3 (see Section 12) to a flange connection at the Sprint skid, at 200-450
kPag.
Lube Oil Systems
The equipment package is supplied with two separate lube oil systems: one for the gas turbine and
one for the generator/gearbox. The oil reservoirs and piping are all stainless steel, and the lube oil
system valves have stainless steel trim. Each lube oil system has duplex filters, duplex Shell and
Tube water coolers, and thermostatic-controlled electric heaters. The oil reservoir, and filters for
each system are mounted on an auxiliary equipment module located next to the gas turbine
baseplate. The auxiliary equipment module provides simplified piping connections and reduces
custome, r's installation time and costs. The gear box/ generator lube oil system is located on the
mineral lube oil module. The Shell and Tube water coolers are mounted on dedicated foundations
and located near the gas turbine baseplate.
Each lube oil system has a lube oil vent separator able to reduce oil emission in the atmosphere as
follows:
Max mineral oil emissions:
Max synthetic oil emissions:
20 mg/Nm3 and average 0.079167 kg/h over a 24-hour period
20 mg/Nm3 and average 0.0375 kg/h over a 24-hour period
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 gas turbine accessory gearbox. Hydraulic hoses are furnished to connect the auxiliary
equipment module and the main baseplate.
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 both
generator and engine compartments. The fire protection system includes cylinders containing CO2
mounted on the auxiliary 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, and the primary CO2
cylinders are discharged into the turbine and generator compartments via multiple nozzles, and the
ventilation dampers automatically close. After a time delay a slow extended discharge of CO2 is
provided.
Winterization
Being the Equipment operating outdoors in relatively cold climates (-15°C absolute minimum
ambient temperature) GE Energy provides the winterization of the Equipment. The winterization
includes the following modifications:
· Inlet air anti-icing (see above)
· Heat tracing and insulation of applicable unit mounted piping
· Enclosing and heat exposed instruments and equipment
For ambient temperatures below -15°C, additional special equipment available as an option will be
required.
Gas Turbine Generator Control System
The equipment package is supplied with a free-standing control panel suitable for mounting in an
indoor, non-hazardous area provided by Customer. The control system key features are:
· Full MicroNetTM (Woodward MicroNet Simplex Digital Control) microprocessor based control
panel for gas turbine fuel/airflow management, and auxiliary system sequencing/protective
functions.
· GE EX2100 AVR.
· Bently Nevada digital microprocessor-based vibration monitor
· Digital generator system multifunction meter (Watts, VARS, Amps, Volts, etc)
· Beckwith M-3425 digital microprocessor-based generator protection system.
· Desk top HMI computer (human machine interface) provides graphical displays in English
language, and logging of key gas turbine, generator, and auxiliary system data. The HMI
software will be Intellution.
· Manual and Automatic Synchronization
The conditions inside the non-hazardous area provided by Customer for GE Energy’s control
panels installation are as follows:
· Design temperature: 26 deg C summer / 20 deg C winter
· Design RH: 65% summer / 30% winter
The operator selects HMI displays with a mouse or trackball. The HMI includes a set of graphic
displays for the gas turbine, its auxiliaries and driven equipment.
Alarm and shutdown events are displayed on the HMI automatically. When an alarm is issued, it is
displayed on the dedicated alarm display on the HMI and sent to the Customer supplied alarm
printer connected to the HMI. Alarm and shutdown events printing are in English language. Alarms
are processed between 5 and 60 milliseconds depending on the scan time in the Micro Net
Controller for a specific function. The operator can identify the first out by reading the time when
the alarm occurred.
The MicroNet is a Simplex control containing a Pentium/NT CPU, that offers very high
performances for this application. The NT CPU module runs the application program. The NT CPU
supports Windows NT with real time extensions to maintain a rigorous real-time environment.
Woodward’s GAPTM (Graphical Application Program) software is the graphical programming tool
specifically designed for quick and easy implementation of complex control strategies.
Woodward’s unique rate group structure ensures that control function will execute deterministically
at rate groups defined by GE Energy. Critical control loops can be processed within 5 milliseconds.
Less critical code is typically assigned to slower rate groups. The rate group structure prevents the
possibility of changing system dynamics by adding additional code. Control is always deterministic
and predictable.
Power for the control panel is provided by a dedicated 24V DC Ni-Cd battery system with dual
100% capacity chargers. The 24V DC battery system provided can supply the control loads for at
least three hours without recharging. This allows the safe shut-down and cool-down of the GTG
without Customer’s UPS.
An Ethernet TCP/IP Modbus or a RS485 Modbus Port is provided to transmit unit conditions
(status, pressures, temperature, etc.) to the customer's Distributed Control System (DCS).
For allow the operation and control of the equipment package as an integrated heat production
plant from the cogeneration DCS provided by Customer, the main I/O hardwired provisions, up to
20 I/Os, (such as: start, stop, start automatic synchronization, power factor increase, power factor
decrease, power output up, power output down) are included.
To allow time synchronization with the Customer’s Distributed Control System, the time
synchronization capability trough GPS is provided. For the time synchronization GE Energy would
utilize a 637PCI card in the HMI which utilizes IRIG-B. The GPS signal should be received from the
Customer’s DCS to the HMI, synchronized with the HMI, MicroNet controller, the generator
protective relay module.
In addition to the alarm display and the Customer supplied alarm printer, all alarms and events are
also automatically logged to a database on the hard drive. The data stored on the hard drive can
be easily retrieved from the HMI desk top. This will bring up a form that will let the operator select
the type of data he is interested in and submit a query.
GE Energy uses the trending features of the HMI for capturing long trending. The MicroNet
communicates to the HMI over ModBus and the update time is 1 to 2 seconds. GE Energy and
Customer will pre-define the variables to monitor or trend in the GAP program but at least all analog
values. The length of time that data is stored on disk before offline archiving is required depends
upon the deadband configuration, process rate of change, and disk size. Buyer may back up the
data on a regular basis on the DVD recorder included in the HMI but no more often than once a
month.
The time stamping for the alarms is occurring in the HMI.
GE Energy provides a suite of software tools (Control Assistant) for the MicroNet control. Providing
additional functionality beyond variable viewing, Control Assistant provides the tools to perform
advanced system diagnostics and other functions. Control Assistant is a suite of three software
products:
· Datalog Capture and Graph View functions provide a powerful graphical tool for viewing
dynamic control variable performance off-line. Millisecond time resolution gives great clarity
to dynamic control transients. Control Assistant's graphical features complement lowerresolution
trends from a traditional HMI, letting you solve problems quickly and get back online
sooner.
· Tunable Maintenance Utility includes the capture, sorting, comparing vs. baseline, saving,
and uploading new tunables to the control. This feature allows a user to download all the
tunable information out of one control system and upload it into another. Or download
tunables from two control systems and compare the difference.
· HEX file download is the utility to load a new program into the control system.
The software tools are available for use in the HMI. Diagnostic messages for hardware limit checks
and all other hardware diagnostics for the board can be accessed with the software tools.
All software licenses required to use or maintain the Woodward MicroNet control panel and HMI
are included in the GE Energy scope of supply
