Compressor Surge Control Using Nonlinear Model Predictive Control Based on LS-SVM", IEEE Transaction on Control Systems.
Compression systems are designed and operated to eliminate or minimize the potential for
compressor surge, a dynamic instability detrimental to the integrity of the unit.
Ingestion of this ash ablates jet engine blades and vanes and the ash can melt to a molten glassy state, causing blockages which can lead to
compressor surge and possible flameout.
Eliminating
compressor surge results in tremendous compressor energy savings and operational benefits such as:
I can guess, though: violent
compressor surge, catastrophic blade failure, severe vibration, primary structure failure, impact into terrain.
Centrifugal
compressor surge and its prevention have drawn significant attention in compressor literature and editorial content.
Compressor surge is sometimes viewed as a common occurrence but design of a proper surge control system should be regarded as both a necessary design practice and an effective risk-mitigation measure.
The retrofit included improving the reliability of the gas turbine fuel control systems, upgrading the
compressor surge control systems, and adding instrumentation to the stations and the turbines to allow for more precise monitoring.
