Detection of Emerging Faults on Industrial Gas Turbines Using Extended Gaussian Mixture Models

Table 1

Stages of the proposed methodology.

Step	Process	Purpose	Output
1	Sensor measurement collection (sampled or batch)	—	Collate data for analysis
2	VBGMM	Preprocess data to remove transient measurements	Measurements only of steady state operation
3	Statistical analysis	Extraction of important features within the data	Features for identifying emerging faults
4	GMMOC	Novelty detection of emerging faults	Early warning of emerging or imminent fault conditions
