Valve tracking logic for trip mitigation
GE Vernova’s valve tracking logic for trip mitigation is an application software enhancement developed to improve TMR reliability and mitigate the risk of gas turbine trip.
Reducing the risk of unit trip
Software to enhance Mark* Ve and Mark VIe triple modular redundancy (TMR)
Benefits:
- Avoid 24 – 48-hour valve-failure downtime, possibly extending to a week without spares
- Extended maintenance and overhaul intervals by 96,000 hours for eGCV/eIGV
- Avoid $10 – $50K in direct costs per failure, not including lost revenue
- Performance recovery of ~0.5% output or improved heat-rate
- Reduced O&M with ~$300K savings in hydraulic valve overhauls, reduced oil filters inventory, no servos needed
Upgrade features
GE Vernova’s software enhancements can prevent a single controller in a tripped state from causing your gas turbine to trip.
Here's how we do it:
- Improved fuel stroke reference (FSR) startup and acceleration schedules to prevent FSR from being latched in at a low value
- Valve oscillation detection algorithm, which allows for opening up the limits on the gas control valve tracking protection
- All equipment can be installed in a single CI, HGP, or MI outage
- Pricing includes significant engineering and materials cost synergies
