Title:
SYSTEMS AND METHODS FOR ICING DETECTION OF COMPRESSORS
Document Type and Number:
Japanese Patent JP2018204604
Kind Code:
A
Abstract:
To provide systems and methods for detecting icing of compressors of a gas turbine system.SOLUTION: A controller 56 is configured to detect an icing condition of an inlet portion of a compressor 24 by: determining a current compressor efficiency value of the compressor, a current compressor flow value of the compressor, or any combination thereof; comparing the current compressor efficiency value to a compressor efficiency model of the compressor, comparing the current compressor flow value to the compressor flow model of the compressor, or performing any combination thereof; and providing an icing indication to an inlet bleed heat system if a first difference between the current compressor efficiency value and the compressor efficiency model is greater than a first threshold, a second difference between the current compressor flow value and the compressor flow model is greater than a second threshold, or if any combination thereof occurs.SELECTED DRAWING: Figure 1
