摘要

As a basic requirement for optimum operation of a power plant efficiency and availability must be kept at their design values. Online diagnostic systems help to achieve thermodynamically optimal operation. Additionally, informations are provided to realize operation with high plant availability. The operation of a power plant is increasingly being supported by systems for monitoring, analyzing and diagnosing the data of important components. Complementing the operational I&C equipment, the systems recognize changes in the behaviour of components which influence plant efficiency and may cause higher fuel consumption. Additionally, such systems ensure plant availability through an early warning in case that signals are significantly changing compared to reference values. Malfunctions can therefore be detected earlier than has been possible up to now and subsequent damage can be precluded. With these features the systems pave the way for a condition-based maintenance strategy thus saving maintenance costs and improving availability. Today's modern computer systems make it easy to work with large data quantities covering extensive periods of operation, for example the interval between two inspections, and permit planning of important maintenance and overhaul work in due time.
