Abstract
Official abstract text for this publication.
A method of detecting faults in a wind turbine generator based on current signature analysis is disclosed herein. The method includes acquiring a set of electrical signals representative of an operating condition of a generator. Further, the electrical signals are processed to generate a normalized spectrum of electrical signals. A fault related to a gearbox or bearing or any other component associated with the generator is detected based on analyzing the current spectrum.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for detecting mechanical faults in an electromechanical machine having multiple electrical phases, the method comprising: acquiring electrical signals for each phase of the multiple electrical phases from one or more sensors representative of an operating condition of the electromechanical machine; normalizing the electrical signals to extract spectral information; and detecting a fault based on analysis of the spectral information compris…
