Description of the research topic:
A significant part of the cost implications of operating the electricity system is due to maintenance interventions and depreciation associated with the reduction in the lifetime of network elements. The efficiency of system interventions can be improved through the application of an asset management system based on the condition monitoring of the network devices. Conventional, failure- and time-dependent maintenance strategies do not allow to identify the relationships between asset status and a failure that has occurred, nor to monitor changes in status information, therefore, customer outages can be significant in case of an equipment failure. The objective of risk-based asset management is to determine the level of intervention and investments required for the whole apparatus by taking into account the expected reliability.
The condition factors generated by the application of asset management make it possible to compare the condition of equipment in different asset categories by taking into account the consumer's exposure. Moreover, it provides the possibility to integrate new intervention methods and innovative technologies. The comparative advantage of asset management is that the lifetime of network equipment can be extended on an information basis, ensuring safe operation beyond their expected lifetime.
Currently, extensive physical models mainly available for substation equipment to track their condition and the calculation of the resulting state factors in a systematic way. On the other hand, power line infrastructure is also a significant part of both the transmission and distribution systems, for which a much smaller number and less detailed physical models are available for condition monitoring of towers, conductors, insulators and fittings. The aim of this research is the physical modeling of the degradation of transmission line infrastructure, on the basis of which a unified condition factor system can be defined. A further objective is to develop a conceptual basis for a risk-based asset management system for transmission lines.
