Generator Users Group : Mechanical Dynamics & Analysis

Recent Generator Findings And Preparing Generator Rotors for Cyclic Duty

THURSDAY, DECEMBER 3, 2020 @ 3pm EST/12pm PST

Presentation Synopsis

Recent Generator Findings presentation will include a percentage breakdown of work in the MD&A shop over the last 18 months in addition to case studies defining: why the unit was brought down, the root cause, the applied repair, and if it was planned work or emergent / forced outage work. Preparing Generator Rotors for Cyclic Duty presentation will include case studies with cycling impacts on generator rotors with actual findings and applied repairs.

Key Takeaways for Users

1 – Be thorough in your investigation when a unit is down, and document everything. Most items can be viewed overtime and will give clues to when a failure will occur. Review these documents before an upcoming outage so you have a good baseline on where you have been.

2 – If your unit is down for any length of time utilize a borescope and get your eyes on the machine (if possible) and take note of everything you see. It never hurts to get additional eyes on your system even if it isn’t a planned outage.

3 – Regular maintenance of the unit should not be delayed if possible. A rigorous inspection and maintenance schedule should be followed whenever possible.
