Understanding the Plant Systems to configure the Plant

TC BC HR EC PI


Systems-based methodology guides configurations Plant configuration requirements

Plant configuration decisions 1. Modularization of GT enclosure 2. Use of plant fieldbus controls 3. Plant layout 4. Steam turbine side exhaust 5. Use of a clutch in single shaft 6. Generator position 7. Simplification of aux systems

1. Plant cost • Enhance equipt packaging • Height of the building • Type/height of foundation • Reduce aux steam need

2. Ease/speed of installation • Dense plant layout • Separation of work • Parallel installation

3. Operability and Maintainability • Fast start up capability • Minimal cranes sizes • Outage laydown space


Re-engineering of GT enclosures and accessories

Plant configuration decision example Modularize GT enclosure and accessories

*7HA.01 compared to 7F.03 **piping between GE supplied equipment

Plant requirements fulfilled • Plant cost • Ease of installation • Speed of installation • Operability • Maintainability

Key value created • Reduced installation*: pre-wired, piped,

shipped assembled … 10k less man-hours • Less connections/welds*: field installed

valves – 451; field welds 525238 • Common interfaces: less field routed pipe,

interconnecting piping provided** • Maintainability built in: roof access, space

to drop combust cans, crane in module


Plant configuration decision example Deploying digital fieldbus technology across the plant


Simplified device couplers instead of junction boxes


Key value created • Reduction in startup and commissioning

time*: pre-configured devices and skids • Less installation cost*: 10,500 man-hours

less than I/O • Less wires and terminations: i.e., MOV

wires 800120; terminations 3,200130 • Enhanced trouble shooting capability:

smart digital devices identify a fault source *FFB compared to traditional I/O MOV – Motor Operated Valve


Plant configuration decision example Plant layout for ease of construction, operations and maintenance

Mechanical work area

Electrical work area

Shaft line work area

1 x 9HA plant layout with separate work areas


Key value created • Layout capable of fast installation: 24

months NTP to COD • Separate work areas for construction:

parallel work with specific tasks • Turbine building through road: for

construction and 34 day major plant outage • Lower building cost: 5m lower* using pier

foundation and side inlet/ST exhaust *FE50 compared to 109F block 3 plant

9HA FlexEfficiency*50 Plant



Key components 9HA gas turbine

World’s largest, most efficient gas turbine

Integrated approach

D650 steam turbine >40% shaft efficiency SS: 3 casing, lateral exhaust MS: Opposed-flow HP/IP

Plant configuration Smaller footprint, improved serviceability

W86 generator Reduced site assembly, enhanced serviceability

Mark Vie* ICS Plant controls Digital architecture, performance seeking algorithms



Enhanced user interface Industry standard Enables faster assessment and

trouble shooting • Simple and intuitive • Actionable information • Easy to use • Quickly recognize items


1x1 9HA FlexEfficiency*50 Power Plant • 600-700 MW, 50 Hz … 61%+ base load efficiency

• Start-up to full load <30 minutes

• Ramp-rate >60 MW/minute

• Plant turn-down to 50% load

• A new standard in efficiency AND flexibility

Summary

Understanding the needs of the plant owner is critical

Develop the plant using Systems Based approach to value creation

Integrating the equipment in the

plant is key to competitiveness
