Project objective

The main objective of the project “Design for Reliable Power Performance” is: to improve the reliability and controllability of offshore wind turbines to reduce the operational uncertainty of future offshore wind power plants. To realize this objective the project is subdivided in four Work Packages (WP) that have the following sub-objectives:  Improve the availability of the electrical generator systems by using modular conversion system concepts that are fault tolerant, re-configurable and self-healing  Generate the knowledge to reduce the uncertainty in the aerodynamic performance and the reliance on failure prone features, allowing for larger and lighter offshore wind turbine blades  Increase reliability and decrease the impact of uncertainty in the cost of the support structure by using integral probabilistic structural design techniques  Develop self-adaptive control algorithms dealing with the variability and uncertainty in environmental conditions and system response (e.g. water depth changes due to tides and/or scour, ice formation, etc.)  Substitute unplanned with planned maintenance by bridging the gap between existing condition monitoring and fault tolerant control schemes

Expected outcome

The Cost of Energy of offshore wind farms is reduced by integral reduction of uncertainties; design for reliability and system identification are applied to re-assess the safety factors and reduce operational uncertainty of the offshore wind turbines.
