We’ve had a couple of surge events during turbine startups lately. What are the best strategies to avoid this issue and ensure smoother startups?
Ensure your variable inlet guide vanes (VIGVs) are properly calibrated. Misaligned vanes often lead to surges during startup.
Monitor your fuel ramp rates closely. Too much fuel too quickly can destabilize the compressor and cause a surge.
Conduct a startup sequence review. We found a programming error in our logic that was triggering surges unexpectedly.
