    Authors: Schepers, J.G.; Brand, A.J.;

    In these full scale aerodynamic test program local aerodynamic quantities (forces, inflow velocities, inflow angles) are measured at several radial positions along the blade.The aerodynamic experiments at ECN were performed in two different phases: The non-rotating phase (1993-1994). In this phase the blade was mounted vertically on a non-rotating facility in the free stream. This test aimed at acquiring data at free stream conditions without rotational effects. Furthermore the instrumentation could be tested relatively easy in order to prepare for the next phase. The rotating phase (1995-1997). In this phase the blade was mounted on the HAT-25 experimental wind turbine and data were acquired under rotation. Furthermore some non-rotating measurements have been repeated. In this report the measurements from the rotating phase are reported only. The HAT-25 wind turbine is located at ECN near Petten in the Netherlands. The prevailing wind direction is from South-West, at which most of the measurements are taken. In this direction, the terrain upstream of the turbine is obscured by dunes over around 600 m. As a result, the turbulence intensities at the site may depend strongly on the conditions. Generally, the values of the turbulence intensities are between 5% and 20%.Time series measurements are supplied, in which the angle of attack ranges from negative values to deep stall values. Also measurements at yaw misalignment and at stand still have been supplied. Also sectional profile coefficients under rotating and 2D conditions are stored. The SourceDatabase.zip archive contains original database with data file formats and conventions harmonized (across all IEA Task 18: Enhanced Field Rotor Aerodynamics experiments) in order to make the full database easy accessible. The rotating phase measurements have been merged into two files: "rottim_prof_merged.csv" (containing profile, SCADA and SHM data) and "rottim_p_merged.csv" (containing aerodynamic pressure measurements) to facilitate import of all the data.  IEA Task 18 Acknowledgement: The support of the IEA R&D Wind Executive Committee which made it possible to cooperate in the Annexes XIV and XVIII is highly appreciated. The measurement programme on the experimental facility of the Netherlands Energy Research Foundation was made possible by financial support from the Dutch Ministry of Economic Affairs (Energy R&D Targeted Funding 1991-1995). In addition support has been obtained by the Dutch Organisation for the Energy and Environment, NOVEM, within the EGIB project (NOVEM project number 224.720.9640) and through NOVEM project number 224.750.9858 The contribution from Risø to the IEA Annex XIV project has been funded by the Danish Ministry of Energy under contract: ENS 1364/94-0001 which is gratefully acknowledged. The U. S. Department of Energy is credited for its funding of the Unsteady Aerodynamics test program through the National Renewable Energy Laboratory under contract number DE-AC36-98-GO10337. The measurement programme from Imperial College/Rutherford Appleton Laboratories was funded by the Department of Trade and Industry, Energy Technology Support Unit and Engineering and Physical Sciences Research Council. The measurement programme from Mie University has been supported by the Japanese Ministry of Education. Furthermore the European experimental programmes were funded through several JOULE projects. These JOULE projects are partly funded by the EU and partly by the participating organisations and/or their national agencies.

    General description of wind turbine: The ETH owned wind turbine is Aventa AV-7, manufactured by Aventa AG in Switzerland and was commissioned in December 2002. The turbine is operated via a belt-driven generator and a frequency converter with a variable speed drive. The rated power of the Aventa AV-7 is 7 kW, beginning production at a wind speed of 2 m/s and having a cut-off speed of 14 m/s. The rotor diameter is 12.8 m with 3 rotor blades, and a hub height is 18m. The maximum rotational speed of the turbine is 63 rpm. The tower is a tubular steel-reinforced concrete structure, supported on concrete foundation, while the blades are made of glassfiber with a tubular steel main-spar. The turbine is regulated via a variable-speed and variable pitch control system. Location of site: The wind turbine is located in Taggenberg, about 5 km from the city centre of Winterthur, Switzerland. This site is easily accessible by public transport and on foot with direct road access right next to the turbine. This prime location reduces the cost of site visits and allows for frequent personal monitoring of the site when test equipment is installed. The coordinates of the site are: 47°31'12.2"N 8°40'55.7"E. Control and measurement systems and signals: The turbine is regulated via a variable-speed and collective variable pitch control system. SHM Motivation: Designed and commissioned in 2002, the Aventa wind turbine in Winterthur is soon reaching its end of design lifetime. In order to assess the various techniques of predicting the remaining useful lifetime, a Structural Health Monitoring (SHM) campaign was implemented by ETH Zurich. The monitoring campaign started in 2020, and is still ongoing. In addition, the setup is used as a research platform on topics such as system identification, operational modal analysis, faults/damage detection and classification. We analyze the influence of operational and environmental conditions on the modal parameters and to further infer Performance Indicators (PIs) for assessing structural behavior in terms of deterioration processes. Data Description: The tower and nacelle have been instrumented with 11 accelerometers distributed along the length of the tower, nacelle main frame, main bearing and generator. Two full bridge strain gauges are installed on the concrete tower based measuring fore-aft and side-side strain (and can be converted to bending moments) – all acceleration and strain signals sampled at 200Hz. Temperature and humidity are measured at the tower base – 1Hz data. In additional we are collecting operational performance data (SCADA), namely: wind speed, nacelle yaw orientation, rotor RPM, power output and turbine status – SCADA signals are sampled at 10Hz.

    General description of wind turbine: The ETH owned wind turbine is Aventa AV-7, manufactured by Aventa AG in Switzerland and was commissioned in December 2002. The turbine is operated via a belt-driven generator and a frequency converter with a variable speed drive. The rated power of the Aventa AV-7 is 7 kW, beginning production at a wind speed of 2 m/s and having a cut-off speed of 14 m/s. The rotor diameter is 12.8 m with 3 rotor blades, and a hub height is 18m. The maximum rotational speed of the turbine is 63 rpm. The tower is a tubular steel-reinforced concrete structure, supported on concrete foundation, while the blades are made of glassfiber with a tubular steel main-spar. The turbine is regulated via a variable-speed and variable pitch control system. Location of site: The wind turbine is located in Taggenberg, about 5 km from the city centre of Winterthur, Switzerland. This site is easily accessible by public transport and on foot with direct road access right next to the turbine. This prime location reduces the cost of site visits and allows for frequent personal monitoring of the site when test equipment is installed. The coordinates of the site are: 47°31'12.2"N 8°40'55.7"E. Control and measurement systems and signals: The turbine is regulated via a variable-speed and collective variable pitch control system. SHM Motivation: Designed and commissioned in 2002, the Aventa wind turbine in Winterthur is soon reaching its end of design lifetime. In order to assess the various techniques of predicting the remaining useful lifetime, a Structural Health Monitoring (SHM) campaign was implemented by ETH Zurich. The monitoring campaign started in 2020, and is still ongoing. In addition, the setup is used as a research platform on topics such as system identification, operational modal analysis, faults/damage detection and classification. We analyze the influence of operational and environmental conditions on the modal parameters and to further infer Performance Indicators (PIs) for assessing structural behavior in terms of deterioration processes. Data Description: The tower and nacelle have been instrumented with 11 accelerometers distributed along the length of the tower, nacelle main frame, main bearing and generator. Two full bridge strain gauges are installed on the concrete tower based measuring fore-aft and side-side strain (and can be converted to bending moments) – all acceleration and strain signals sampled at 200Hz. Temperature and humidity are measured at the tower base – 1Hz data. In additional we are collecting operational performance data (SCADA), namely: wind speed, nacelle yaw orientation, rotor RPM, power output and turbine status – SCADA signals are sampled at 10Hz. See appendix for further details of the sensors layout. The measurements/instrumentation setup, type and layout is provided in the pdf files. The data: the data is provided in zip files corresponding to four use-cases as follows: Normal operation data for system identification Aerodynamic imbalance on one blade Rotor icing event Failure of the flexible coupling of the linear drive of the collective pitch system The data for each of the four uses-cases is organized in zip files. The content of each zip file is as follows: Time-series data in HDF5 format Metadata: Turbine specification (Aventa-AV-7.json and Aventa-AV-7.yaml) Sensor specification (Aventa_sensors.json ) Unstructured description of the Aventa Turbine and the installed sensors (Aventa_Sensors_Specs.xlsx) Semantic artifacts: WindIO Wind Turbine YAML schema describing turbine specifications (IEAontology_schema.yaml) Sensor specification JSON schema (sensors_schema.json) Media: Pictures of leading edge roughness and a clip of wind turbine operation Code: Jupyter notebook containing example code to load metadata from JSON and data from HDF5 files (example.ipynb) Additional data is available upon request, please contact: Prof. Dr. Eleni Chatzi (chatzi@ibk.baug.ethz.ch) Dr. Imad Abdallah (ai@rtdt.ai , abdallah@ibk.baug.ethz.ch) For further details or questions, please contact: Prof. Dr. Eleni Chatzi Chair of Structural Mechanics & Monitoring ETH Zürich http://www.chatzi.ibk.ethz.ch/

    Authors: Schepers, J.G.; Brand, A.J.;

    In these full scale aerodynamic test program local aerodynamic quantities (forces, inflow velocities, inflow angles) are measured at several radial positions along the blade.The aerodynamic experiments at ECN were performed in two different phases: The non-rotating phase (1993-1994). In this phase the blade was mounted vertically on a non-rotating facility in the free stream. This test aimed at acquiring data at free stream conditions without rotational effects. Furthermore the instrumentation could be tested relatively easy in order to prepare for the next phase. The rotating phase (1995-1997). In this phase the blade was mounted on the HAT-25 experimental wind turbine and data were acquired under rotation. Furthermore some non-rotating measurements have been repeated. In this report the measurements from the rotating phase are reported only. The HAT-25 wind turbine is located at ECN near Petten in the Netherlands. The prevailing wind direction is from South-West, at which most of the measurements are taken. In this direction, the terrain upstream of the turbine is obscured by dunes over around 600 m. As a result, the turbulence intensities at the site may depend strongly on the conditions. Generally, the values of the turbulence intensities are between 5% and 20%.Time series measurements are supplied, in which the angle of attack ranges from negative values to deep stall values. Also measurements at yaw misalignment and at stand still have been supplied. Also sectional profile coefficients under rotating and 2D conditions are stored. The SourceDatabase.zip archive contains original database with data file formats and conventions harmonized (across all IEA Task 18: Enhanced Field Rotor Aerodynamics experiments) in order to make the full database easy accessible. The rotating phase measurements have been merged into two files: "rottim_prof_merged.csv" (containing profile, SCADA and SHM data) and "rottim_p_merged.csv" (containing aerodynamic pressure measurements) to facilitate import of all the data.  IEA Task 18 Acknowledgement: The support of the IEA R&D Wind Executive Committee which made it possible to cooperate in the Annexes XIV and XVIII is highly appreciated. The measurement programme on the experimental facility of the Netherlands Energy Research Foundation was made possible by financial support from the Dutch Ministry of Economic Affairs (Energy R&D Targeted Funding 1991-1995). In addition support has been obtained by the Dutch Organisation for the Energy and Environment, NOVEM, within the EGIB project (NOVEM project number 224.720.9640) and through NOVEM project number 224.750.9858 The contribution from Risø to the IEA Annex XIV project has been funded by the Danish Ministry of Energy under contract: ENS 1364/94-0001 which is gratefully acknowledged. The U. S. Department of Energy is credited for its funding of the Unsteady Aerodynamics test program through the National Renewable Energy Laboratory under contract number DE-AC36-98-GO10337. The measurement programme from Imperial College/Rutherford Appleton Laboratories was funded by the Department of Trade and Industry, Energy Technology Support Unit and Engineering and Physical Sciences Research Council. The measurement programme from Mie University has been supported by the Japanese Ministry of Education. Furthermore the European experimental programmes were funded through several JOULE projects. These JOULE projects are partly funded by the EU and partly by the participating organisations and/or their national agencies.
