Nedbringelse af Cost of Energy (CoE) fra vindmøller igennem reduktion af fejl i pitchsy-stemet

This project aims to improve the uptime in wind turbines by improving the reliability of the hydraulic system, thus reducing the downtime due to pitch system faults by >15%, lowering the Levelized Cost of Energy and ensuring a more stable supply. This is done by developing and improving methods and knowledge to predict when and why a component is failing and using this information for online monitoring of the systems.

Specifically, the project is organized around a number of work packages, dealing respectively with infor-mation gathering, reliability modelling and lifetime prediction, accelerated testing of components, condition monitoring, fault detection and diagnostics, and fault tolerant control enabling the operating of the system under certain types of faults. The knowledge generated will thus be used to more accurately predict the remaining lifetime, when a system needs servicing, for online monitoring of the systems to plan preventive service (so-called predictive maintenance), and for lifetime design optimization. The results will thus both be implemented through methods and procedures for design and testing of systems, both also in form of on-board diagnostics systems implemented in the pitch system to provide feedback about current state and future service requirements.
