Methods and Systems for Blade Health Monitoring

摘要

Systems and methods for blade health monitoring are provided. According to one embodiment of the disclosure, a system may include a feature extraction module and an anomaly detection module in communication with the extraction module. The feature extraction module may be configured to continuously receive blade passing signal data associated with clearance of a blade and pre-process the blade passing signal data. Blade clearance feature data may be extracted from the blade passing signal data prior to transmission to the anomaly detection module. The anomaly detection module may be configured to normalize the blade clearance feature data received from the extraction module, analyze the blade clearance feature data to detect a shift in the clearance of the blade, and determine an abnormality of the blade based on the shift exceeding a predetermined shift threshold.

1. A method for blade health monitoring, the method comprising:
continuously receiving, from an extraction module, blade passing signal data associated with a clearance of a blade, wherein the blade passing signal data is pre-processed by the extraction module; extracting blade clearance feature data from the blade passing signal data; normalizing the blade clearance feature data; based at least in part on the blade clearance feature data, detecting a shift in the clearance of the blade; evaluating the shift in the clearance of the blade; and determining at least one abnormality of the blade based at least in part on the shift exceeding a predetermined shift threshold.
