Decision Support for Maintenance Management of High Voltage Components

Transmission and distribution components in the power network are capital intensive assets, which force the owners of these assets to utilise them in the most efficient way. Efficient utilisation demands a thorough analysis of the relation between the assets performance and the stakeholders´ expectations. To support electrical engineers in the interpretation of diagnostics on behalf of assessment of the condition of high voltage components, and to aid the as set management in above mentioned analysis, linkage between different information domains has to be brought about to generate the required decision knowledge. Because of the large amount of components, the diversity of component types and measurement data, information systems are needed for storage, correlation and comparison of measurement data on specific components and specific component types. Nowadays, however, decisions will have to be based on more than this technical information alone. A more integral approach is required, paying attention to all stakeholders´ expectations. This paper discusses research performed on modelling the asset management decision process to provide support during the decision process
