Key Issues on Turbomachinery Controls
Key Issues on Turbomachinery Controls
• Energy consumed by turbomachinery is a major cost of operation in process plants and oil production operations
• Poor control is a major risk to the safe and reliable operation of turbomachinery
• The economic consequences of non-availability of turbomachinery is large
• Poor control can lead to false limitations on production
• Capable support services are critical to the successful application of turbomachinery controls

Profit Enhancement Opportunities for CCC Customers
Profit Enhancement Opportunities for CCC Customers
• Maximize reliability of machinery and process:– Prevent unnecessary process trips and
downtime– Minimize process disturbances – Prevent surge, overspeed and associated
damage – Automate startup and shutdown
• Increase efficiency of machinery and process:– Operate at lowest possible energy levels– Minimize antisurge recycle or blow-off– Optimize loadsharing of multiple units– Operate close to limits, safely

Control Retrofits are Economically Attractive
Control Retrofits are Economically Attractive
• Typical turbomachines last 30 years or more
• Control systems are technically obsolete in 10 years
• Old control systems may not be maintainable due to unavailability of Electronic component
• Newer control systems offer– Better performance– Better machinery protection– Better system availability
• Improved electronic components• Redundancy
• ROI (Return On Investment) can be attractive due to production increases and energy savings

Challenges and opportunities in gas turbine control
• Integration with controls of driven object (compressor, generator or pump)
The Control system of both the Gas Turbine as well as the compressor on the same seamless platform
Better control system in order to maintain or maximize machine and associated process reliability.

ClassificationsClassifications• Application
– Fixed speed - electrical power generation– Variable speed- mechanical drives, pumps, compressors
• Design– Industrial, heavy duty, robust long life– Aircraft derivative, lightweight, derated for stationary
applications
• Rotor– Single shaft (usually generator applications)– Dual shaft– Three shaft (aeroderivative types)
• Cycle– Simple cycle– Regenerative– Cogeneration, waste heat

2nd stage nozzle control2nd stage nozzle control
• Why Nozzles– Second stage Nozzles allow the HP turbine to run at its
optimal speed for better fuel efficiency. They remain at EGT limit
• Control implication– There is a strong interaction between NHP, FCV and Nozzle
control. This requires decoupling of controllers
• Start-up– Nozzles are open during start-up – Close at NHP idle speed
• Which GT’s has them– General Electric FS3002 and FS5002– Nuovo Pignone PGT5 and PGT10

CCC 8420 Fuel Valve
The 8402 Fuel Control Valve
• A high quality, high performance fuel control valve • The 8402 is equipped with an electric stepper motor actuator
which can fully stroke the valve in only 250 milliseconds. • The valve has a 500:1 turn down ratio to provide precise fuel
delivery to the turbine from light off to maximum power. • The digital encoder for position measurement provides position
repeatability of 0.05 %.

What Can Be ImprovedWhat Can Be Improved
Avoidance of flame out- Fuel valve movement limiting during surge detection .
Limit the fuel valve rate of change limit for a specified time.
Avoidance of Over temperature trip- Derivative Exhaust temperature set point reduction.
As function of the rate of change of the EGT and CDP
Avoidance of Surge- Integrated control solution by using:
•Feed forward and De-coupling between all controllers•Patented control algorithms
–Derivative Close and open loop control –Pressure override control

• Tests:– Conventional PID control only– Conventional PID control and restricted FCV movement– Conventional PID control with Recycle Trip (open loop
response) and restricted FCV movement– Fully integrated control
• Settings:– Control settings were identical for all four tests
• Starting point:– Compressor with discharge valve fully open– Maximum discharge pressure– Recycle valve closed
• Test:– Step to close position of the process compressor discharge

ConclusionsConclusions
• Gas turbine Fuel stroke limiting during a surge event:– Avoids a Gas turbine “loss of flame” trip– Reduces the magnitude of thermal and mechanical
stresses – Doesn’t affect the process response
• Exhaust temperature set point reduction– Prevents the gas turbine from an over temperature trip– Eliminates the need for unnecessary big control margins
on the Exhaust Gas Temperature limit
• Integrated solution– Avoids surge– Reduces the number of surge events, if they happen– Reduces the magnitude of process upsets– Reduces the magnitude of thermal and mechanical
stresses

Production IncreaseProduction Increase
• Customer had lowered EGT limit set point to eliminate tripping on EGT trip limit due to poor gas turbine control system
• Increase set point from 650 C to 660 C which is original OEM set point
• Results– 3.8% increase in Exhaust Gas Horsepower (EGHP)
– Translating this to the compressor map results in a 6000 Nm3/hr increase in flow at constant compression ratio
– 300 days/yr * 24 hrs/day * 6000 Nm3/hr = 43,200,000 Nm3/yr increased production
Equals $4,860,000/yr in increased production per machine!

System AvailabilitySystem Availability
• In the Past, Most Comparisons Have:– Focused on “The Box”, not on the Entire System.
– Used Oversimplified Models.
– Used a Safety System Mindset, Focusing Only on Dangerous Failures, and Not on the Total Failure Rate of Devices and the System.
– Ignored Controller Diagnostics, Common-Cause Failures, and Other Important Considerations.
• This Approach is Too Simplistic, and Leads to Invalid Conclusions.

ConclusionsConclusions
• Availability analysis comparing controllers alone is not valid. The complete control system must be considered.
• Improving control system availability is best accomplished through increasing the effective availability of field devices.
• Hardware redundancy and software fallback strategies can both be very effective at increasing sensor availability.
• High-reliability output devices provide cost-effective availability increases.
• Automated partial-stroke valve testing isbeneficial if performed frequently.

Increase compressor system reliability and availability with fall-back strategies
Increase compressor system reliability and availability with fall-back strategies
• Over 75% of the problems are in the field and not in the controller
• The CCC control system has fall-back strategies to handle these field problems
• The controller continuously monitors the validity of its inputs
• If an input problem is detected the controller ignores this input and automatically switches to a fall-back mode

Acceptance Test RequirementsAcceptance Test Requirements
• Acceptance test requirements for new control systems– Antisurge Control
• In response to full closure of a substation suction or discharge block valve, the system must not allow any compressor to surge.
• In response to the simultaneous closure of both suction and discharge block valves, the system should not allow any compressor to surge more than once.
– Discharge Pressure Control• In steady state, deviation of the discharge pressure from its
set point shall not exceed 0.5 %.
– Load-Sharing Control• In response to bringing a compressor on-line or taking one
off-line, the control system shall reestablish steady-state operation with all units equally loaded (within 1%) in no more than 30 minutes.

Acceptance Test RequirementsAcceptance Test Requirements
– Turbine Speed Control• In steady state, deviation of the turbine speed from its
set point shall not exceed 0.5%.
– Turbine Limiting Control• In response to a rise in the speed set point, the system
shall not allow an increase in speed after the exhaust-gas temperature has exceeded its limiting control threshold by 0.5% of the sensor span.
• In response to a rise in the speed set point, the system shall not allow an increase in speed after the air-compressor discharge pressure has exceeded its limiting control threshold by 0.1% of the sensor span.
• In response to a rise in the speed set point, the system shall not allow an increase in speed after the uncontrolled shaft speed has exceeded its limiting control threshold by 0.5% of span.
