Special Issue Information

Dear Colleague,

The structural design of wind turbines is traditionally performed using deterministic/semi-probabilistic approaches, where characteristic values and safety factors are applied. Probabilistic approaches can be applied for more detailed modelling, where data can be utilized to improve assessments and reduce uncertainties; in addition, they can be used for direct reliability-based design, for calibration of semi-probabilistic approaches, and for assessments for life extension. Further, probabilistic modelling is an essential part of risk- and reliability-based integrity management (inspection and maintenance planning) and for risk-based assessments of wind turbine structures and wind farms.

The aim of this Special Issue is to collect the latest advances in the field of probabilistic design and assessment of wind turbine structures. Topics of interest for publication include, but are not limited to:

  • Probabilistic design of structural components;
  • Reliability analysis of wind turbine structural components;
  • Assessment of wind turbine structures for life extension;
  • Quantification of uncertainties;
  • Probabilistic assessments based on data;
  • Probabilistic derivation of semi-probabilistic approaches;
  • Risk- and reliability-based inspection and maintenance planning for wind turbine structural components;
  • System reliability assessments for wind turbines and wind farms;
  • Risk-based decision making;
  • Value of information analyses;
  • Derivation of target reliabilities.

The IEC 61400-1 standard specifies design load cases (DLCs) to be considered in the design of wind turbine structures. Specifically, DLC 2.3 considers the occurrence of a gust while the turbine shuts down due to an electrical fault. Originally, this load case used a deterministic wind event called the extreme operating gust (EOG), but the standard now also includes an approach for calculating the extreme response based on stochastic simulations with turbulent wind. This study presents and compares existing approaches with novel probabilistic design approaches for DLC 2.3 based on simulations with turbulent wind. First, a semiprobabilistic approach is proposed, where the inverse first-order reliability method (iFORM) is used for the extrapolation of the response for electrical faults occurring at a given rate. Next, three probabilistic approaches are formulated for the calculation of the reliability index, which differs in how the aggregation is performed over wind conditions and whether faults are modeled using a Poisson distribution or just by the rate. An example illustrates the methods considering the tower fore-aft bending moment at the tower base and shows that the approach based on iFORM can lead to reductions in material usage compared to the existing methods. For reliability assessment, the probabilistic approach using the Poisson process is needed for high failure rates, and the reliabilities obtained for designs using all semiprobabilistic methods are above the target level, indicating that further reductions may be obtained via the use of probabilistic design methods.

Assessing the structural health of operational wind turbines is crucial, given their exposure to harsh environments and the resultant impact on longevity and performance. However, this is hindered by the lack of data in commercial machines and accurate models based on manufacturers’ proprietary design data. To overcome these challenges, this study focuses on using Gaussian Process Regression (GPR) to evaluate the loads in wind turbines using a hybrid approach. The methodology involves constructing a hybrid database of aero-servo-elastic simulations, integrating publicly available wind turbine models, tools and Supervisory Control and Data Acquisition (SCADA) measurement data. Then, constructing GPR models with hybrid data, the prediction is validated against the hybrid and SCADA measurements. The results, derived from a year of SCADA data, demonstrate the GPR model’s effectiveness in interpreting and predicting turbine performance metrics. The findings of this study underscore the potential of GPR for the health and reliability assessment and management of wind turbine systems. Full article
