In November 2023, an Alert was raised by the Anomaly Detection Engine (ADE) on the Air Cooler Output RTD Average (calculated) tag. The second contributing factor was the Cooling Water Output RTD tag, the third was Ambient Temperature, the fourth was Turbine Guide Bearing Temperature, and finally, the vibration on the Guide Bearing. When cooling […]

The Health Score (HS) for one hydropower generator was deteriorating over time. In April 2023, the HS reached a low of 88%. After a maintenance event correction, the HS was back up to the historically normal level of 95%. In addition to the vibration trends returning to normal levels, the Health Score also returned to

Vibration data from the Alert generated on March 4, 2023, shows the initiation of the defect, shown in the green box below. The vibration anomaly increased the amplitude on one of the vibration probes. For this machine, amplitudes below 6 Mils (0.006 inches displacement, peak-to-peak) are considered good. The Acceptable amplitude region is from 6

The Anomaly Detection Engine (ADE) feeds its results to the Apparent Cause Engine (ACE), and based on factors that may include a Failure Modes and Effects Analysis (FMEA), Action Recommendations are generated. Limiting the ACE with FMEA increases the probability of an accurate diagnosis by the ACE. Remember, these are specifically built, intentional outputs for

RTDs provide temperature measurements and in the case for the image below, the air cooling (Out and In) are the two largest contributing factors impacting the Anomaly Score. The MVAR and TopOilTemp tags are the lowest of the top five relative contributors to the Anomaly Score. Alerts and Recommendations may be generated by clicking on

A good Asset Management program requires some time-based activities, such as filter changes and lubrication events. The challenge is in performing scheduled maintenance activities on time to keep a low-risk profile. Skipping or deferring maintenance items will increase problems over time. In Hydro Generation, if air cooler fouling is left untreated, daily operations can be
