The Practical Application of On-Line Systems to the Diagnosis of Machine Problems
The diagnosis of problems on rotating machinery, particularly large turbines, has been significantly advanced in recent years by the use of systems monitoring and analysing vibrations on line. The specification of many of these systems has been developed however from the requirements of the vibration analyst. Consequently the emphasis has been placed on the speed and capacity at which they can gather their data, rather than the presentation of information to the Station engineers in simple formats relevant to the operation of their machine.
This paper describes the features of an on-line turbine monitoring system developed for the UK Power Industry which is now in operation in five UK Power Stations. The cdmmunication of information to the operational and maintenance staff is a key feature of the system and has enabled them to fully participate in routinely identifying and resolving turbine problems. Several examples are used to illustrate how the data acquired have been used in this process.
