Projet
HT-20MW
Electrical connection hub and application for a wind turbine for a 20 MW wind turbine
- Duration: 48 months (2023-2027)
- Budget: €6,200K
Context
France wants to position itself as the world’s leading manufacturer of floating wind turbines. To meet these ambitions, the industry needs to organise itself to offer more competitive solutions and develop its industrial facilities to produce locally and in series. Furthermore, extending the offshore interconnection grid is vital if the energy generated by floating wind turbines is to be fully exploited.
The first link in this grid is a high-power rotating electrical connection for machines that orient themselves into the wind. Mooring lines are also key components. While new materials are available, they do not yet have sufficient feedback to be deployed commercially on a large scale.
Objective
- To design, test and certify a high-voltage rotating mechanical and electrical connection that is watertight and maintenance-free for 10 years
Scientific content
Parameterisation and coding of the behaviour of polyamide mooring lines in commercial software
Identification of failure modes for mooring lines and dynamic cables
Local and global numerical modelling of the dynamic cable, carrying out sea trials for in-service monitoring
Fatigue testing of dynamic cables and mechanical testing of mooring lines
Analysis of standards and certifications for mooring lines and electrical connections
Design and full-loading analysis of a 20 MW wind turbine
Design, manufacture and assembly of the mechanical and electrical parts of the rotating connection
Basin tests on a reduced-scale model of the 20 MW wind turbine
Expected results
- Qualification of an in-service monitoring solution for dynamic cables
- Qualification of external protection solutions for mooring lines and dynamic cables
- Methodological note on fatigue and extreme loadings of mooring lines
- Numerical model of a 20 MW wind turbine for fixed and floating applications
- Design and demonstration of the wind turbine’s rotating connection
