System and method for blind fault detection for rotating machinery

摘要

A system includes more sensors configured to measure one or more characteristics of rotating equipment and a blind fault detection device. The blind fault detection device includes an input interface configured to receive at least one input signal from the one or more sensors. The blind fault detection device also includes a processing unit configured to identify a fault in the rotating equipment using the at least one input signal. The blind fault detection device further includes an output interface configured to provide an indicator identifying the fault. The processing unit is configured to identify the fault by determining at least one family of frequencies related to at least one sensor point, determining an average energy for the at least one sensor point based on the at least one family of frequencies, and comparing the average energy to a baseline value.

1. An apparatus comprising:
an input interface configured to receive input signals from sensors associated with at least one stage of rotating equipment; a processing unit configured to identify a fault in the rotating equipment using the input signals; and an output interface configured to provide an indicator identifying the fault; wherein the processing unit is configured to identify the fault by: monitoring multiple families of frequencies in the input signals; determining at least one average energy based on the multiple families of frequencies; and comparing the at least one average energy to at least one baseline value; and wherein the at least one average energy comprises an average energy of the multiple families of frequencies in the input signals from multiple sensors located at a common sensor point and having different measurement orientations.
