Adaptation of existing wind turbines for operation on high wind speed complex terrain sites; kWh cost reduction. The ADAPTURB project

摘要

The main objective of the project is the examination of the total design envelope criteria of existing selected Wind Turbines (WT) for complex terrain operation (Stall, Pitch, Variable Speed, and Teeter concepts) in relation to the IEC-61400-1 standard, the wind climate and the complex terrain wind structure, as well as to investigate the potential for increase in WT energy production and/or decrease in loading that can be attained through feasible WT adaptations. To this end, new rotor designs for Stall and Pitch WTs adapted for operating on highly complex terrain sites with very high wind speeds are investigated along with controller parameter optimization. The objective is supported by the implementation of the findings of the research test and development work on selected WTs operating on highly complex terrain sites, while the final target will be to fully quantify and verify the performance of the adapted WTs through detailed wind, load, power and machine condition measurement programs on the adapted WTs. In this work the project results are presented, particularly those referring to databases documentation and design envelope assessment results and guidelines, which are of utmost importance for standardization and certification purposes. Therefore, the presented results are expected to be of interest also to the European certification organizations. In addition to that, the European Standardization work performed by CEN/CENELEC would also be benefited.
