Most fossil-fuelled power stations are used as base- or middle-load power stations. In these applications in particular, the highly sensitive monitoring of the normal operation and the analysis of run-up and run-down procedures is of significant importance.
The operating condition dependant monitoring of the normal operation enables abnormal deviations of the behaviour of the machine to be recognised at an early stage.
As in other applications for power generation, some main characteristics of modern monitoring and diagnostic systems are
