RESEARCH & DEVELOPMENT
COMMON INDUSTRY PRACTICE It remains common industry practice to base energy production estimates on sales power curves coupled with a single wind speed prediction at hub height only. Prevailing continues to invest considerable R&D effort in improving the estimation of site-specific turbine performance. These methods take into account predicted and measured flow conditions, nearby forest, turbine positioning, hub height and rotor size. Wind flow across the whole rotor is considered.
DEVELOPMENTS CONTINUE IN THE FOLLOWING AREAS… • Operational observations of actual turbine performance in varying conditions
• CFD-based wind flow modelling validated with site measurements
• Aero-elastic rotor modelling for direct simulation of performance variation
• Industrial and academic collaboration • Efficiency gains to reduce computation time and cost
Continuous improvement in these methods relies on extensive validation and strong feedback from analysis of operational wind farms.
TURNING COMPLEX DATA INTO A DECISION MAKING TOOL
These techniques generate very substantial and complex data sets. Distilling this information into a real developer decision making tool is vital. Prevailing is able to provide both intuitive performance risk maps at the design stage (as seen within the image) and quantified expected performance variation for independent assessment purposes.
Prevailing provides a wide range of analysis tools, to enable confident decision making at each stage of a project life cycle from feasibility to finance.
