Optimising turbo-alternator performance with vibration analysis: A case study
Generating more power from turbo-alternators is increasingly important in today’s competitive generation market. Achieving this can involve plant modifications or enabling each unit to generate for longer periods between maintenance cycles. Adopting a maintenance strategy based on actual needs, rather than preventative schedules, can keep the plant operational while saving significant amounts of money.
To implement this strategy, it's crucial to determine the plant's condition in a cost-effective and non-invasive manner. One of the most effective methods for monitoring rotating plant is vibration analysis.
Vibration analysis allows for the continuous monitoring of machinery health, providing early detection of potential issues before they lead to significant failures. By monitoring vibration levels, it is possible to identify imbalance, misalignment, bearing wear, and other mechanical problems. This proactive approach helps in scheduling maintenance activities based on the actual condition of the equipment rather than on a predetermined schedule, leading to improved reliability and reduced downtime.
