DETECTING ROTOR ANOMALIES DURING TRANSIENT SPEED OPERATIONS

摘要

A computing system for detecting anomalies in a rotor during a transient speed operation is provided which includes a first computing device programmed to identify a baseline sample set including a plurality of baseline samples. The computing device collects a plurality of current vibration samples from at least one vibration sensor during the transient speed operation, including a first current vibration sample including a first rotational speed measurement of the rotor and a first vibration measurement. The computing device selects one or more baseline samples from the baseline sample set based at least in part on the first rotational speed. Each baseline sample includes a baseline vibration value. The computing device compares the first vibration measurement to one or more baseline vibration values of the selected one or more baseline samples. The computing device transmits an alert to a monitoring device based at least in part on the comparing.
