Background and Motivation for Modernization of a Steam
Turboset
Why investing in a Turboset?
Wear and tear of originally installed electronic, electrical and related
mechanical components
Spare parts are expensive or no longer available
Extensive overhaul work for the mechanical control and safety
system
► Decreasing In-Market Availability
Changing market requirements ( Derugalation )
Low degree of automation, less operational flexibility
Requirement for a Life Time Extension
► Decreasing Profitability of the Plant
Page 7
Energy Sector
In Market Availability and Operational Flexibility
“In-Market Availability” – is a measure of how successfully a generating plant
captured the revenue earning opportunities in the market over a period of time”
Power Delivery at a required point of time
“Operational Flexibility” – Ability of your power plant to adjust load output
fast and predictable to changing market/dispatch requirements
Page 8
Frequency control and ancillary services
High startup reliability under all turbine conditions
Load change predictability
Controllable load changes and load ramps
Fast start up and shut down
Energy Sector
More plants (mainly older plants)
predicted to be dispatched as
intermediate duty plants
Few plants (mainly new plants with
high efficiency) have the
opportunity to run base loaded
Progressing deregulation of the
power market
Operating hours per year
The Turkish Power Market
New plants operate in base-load regime …
… Implementation of up-to-date technology
results in lowest electricity costs
… while a shift to intermediate load
is expected during lifetime …
… due to competition with new plants.
Lifetime
Potential revenues for increased
flexibility and availability
Therefore advanced solutions for faster starts and
better cycling capability of the power plants necessary

What we achieve:
1 Security for the machine

Frequency control is not possible,
since the turbine's mechanic control
devices are too slow
Valve position control is imprecise
due to mechanical loose
Complex mechanical control valve
