Projektbeschreibung
Neue Instrumente zur Verwaltung der Vermögenswerte bei Windkraftanlagen
Europas drängende Herausforderung des übermäßigen Energieverbrauchs erfordert nachhaltiges Ressourcenmanagement. Die Windenergie ist zwar eine der wichtigsten erneuerbaren Energiequellen, doch die Lebensdauer und das Management von Windkraftanlagen werfen erhebliche Probleme auf. Die vorhandenen Instrumente haben nicht mit den Fortschritten in der Windkraftanlagentechnologie Schritt gehalten, sodass Sichtprüfung und Offline-Bewertung die Norm sind. Vor diesem Hintergrund wird im Rahmen des EU-finanzierten Projekts WINDMIL ein intelligenter Rahmen für die Überwachung, Prüfung und Lebenszyklusbewertung von Windkraftanlagen vorgeschlagen. Dabei werden erschwingliche Sensortechnologie, modernste numerische Modellierung und Datenverarbeitungswerkzeuge zu einem umfassenden Ansatz kombiniert. Mithilfe der Zusammenführung von Informationen über das Strukturverhalten, der Simulation von Einflussfaktoren und der Anwendung eines stochastischen Rahmenwerks wird innerhalb von WINDMIL an der Bereitstellung eines revolutionären „Schutzanzugs“ gearbeitet, der aus Hardware-Sensoren und einem modularen Softwarepaket besteht.
Ziel
The excessive energy consumption that Europe is faced with, calls for sustainable resource management and policy-making. Amongst renewable sources of the global energy pool, wind energy holds the lead. Nonetheless, wind turbine (WT) facilities are conjoined with a number of shortcomings relating to their short life-span and the lack of efficient management schemes. With a number of WTs currently reaching their design span, stakeholders and policy makers are convinced of the necessity for reliable life-cycle assessment methodologies. However, existing tools have not yet caught up with the maturity of the WT technology, leaving visual inspection and offline non-destructive evaluation methods as the norm.
This proposal aims to establish a smart framework for the monitoring, inspection and life-cycle assessment of WTs, able to guide WT operators in the management of these assets from cradle-to-grave. Our project is founded on a minimal intervention principle, coupling easily deployed and affordable sensor technology with state-of-the-art numerical modeling and data processing tools. An integrated approach is proposed comprising: (i) a new monitoring paradigm for WTs relying on fusion of structural response information, (ii) simulation of influential, yet little explored, factors affecting structural response, such as structure-foundation-soil interaction and fatigue (ii) a stochastic framework for detecting anomalies in both a short- (damage) and long-term (deterioration) scale.
Our end goal is to deliver a “protection-suit” for WTs comprising a hardware (sensor) solution and a modular readily implementable software package, titled ETH-WINDMIL. The suggested kit aims to completely redefine the status quo in current Supervisory Control And Data Acquisition systems. This pursuit is well founded on background work of the PI within the area of structural monitoring, with a focus in translating the value of information into quantifiable terms and engineering practice.
