Optimizing Preventive Maintenance for Steam Turbine Generators

Question:

Currently, we are optimizing our preventive maintenance (PM) procedures, specifically focusing on our steam turbine generator. Our PM plan consists of a 5-year major overhaul and annual electrical inspections of the commutator and excitator. Additionally, we conduct vibration and oil testing on both components. If anyone has examples of their PM practices to share or can recommend resources online, please feel free to pass them along. Your input is greatly appreciated. Thank you.

Have you been able to pinpoint the reasons behind the generator components failing during your rebuild and maintenance efforts? It's important to tailor the maintenance program to address these specific failure mechanisms.

I'm glad to see your thorough approach to PM, it's often overlooked but so critical in the long run. You might want to consider thermographic inspections of your connections, both electrical and mechanical, particularly in your generator area. This can reveal hot spots that could indicate high resistance, friction or misalignment issues long before they become serious problems. As a resource, I'd recommend checking out the Maintenance and Reliability Best Practices group on LinkedIn – a lot of experienced professionals share their insights on similar topics.

It sounds like you already have a good system in place, focusing not only on intervals, but also on condition-based maintenance. Your practice of vibration and oil testing is especially laudable as it helps determine the health of your equipment. One resource I would recommend is The Plant Maintenance Resource Center (www.plant-maintenance.com), it has a great collection of articles and case studies related to preventive maintenance strategies. They have extensive content on a variety of PM practices applied across different industries. You might find their information regarding predictive maintenance and reliability centered maintenance particularly helpful.

Sounds like you already have a solid PM plan in place. However, some additional practices could certainly enhance it further. For instance, implementing thermographic inspections of your electrical system can catch abnormalities invisible to the human eye. This can be paired with your annual electrical inspections for a more comprehensive approach. Also, regarding resources, connex.energy is a go-to for me. It’s an online platform with a wealth of information about facility management and maintenance, especially pertaining to energy solutions. Hope this helps boost your preventive maintenance game!
