Optimizing power transmission networks resilience: Development of tools for monitoring and analyzing the reinforcement of conductors subjected to extreme climatic loads

Our energy transition to renewable energies is intimately related to the performance of our power transmission networks. In operation for several decades now, the ageing of these infrastructures poses major challenges, especially in maintaining their reliability when considering the impact of climate change. In this context, overhead conductors are particularly vulnerable to wind and ice loads. Solutions that are better adapted to current and future problems are needed to ensure the reliability and resilience of our networks. Carried out in partnership with PLP Canada, this research project proposes the development of analysis and control tools designed to increase the resilience of conductors to extreme climatic loads. The work is organized around three specific objectives, each associated with separate master's and/or PhD projects:

1. Characterization of the dynamic behaviour of conductor spans using advanced modelling, including fluid-structure interactions
2. Development of a new vibration damper concept including energy harvesting and multi-modal capacities.
3. Optimization of overhead conductor repair methods based on finite element modelling.
