The data acquisition system has been designed and implemented by Ris together with students and teachers from DTU. It is based on LabVIEW combined with MySQL database for data management. The system enables online access for real-time recordings, which are used both for demonstration purposes, in individual [student] exercises and in scientific investigations. Long-term registration of wind turbine loads results in unique database of non- commercial time series, which are available for practicing fatigue calculations and extreme loads estimation in basic wind turbine courses. Power quality analysis is carried out based on high speed sampled, three-phase voltage and current signals. The wide spectrum of sensors enables detailed study of the correlation between meteorological, mechanical and electrical quantities. Measurements are acquired by PC placed at the wind turbine site near Ris National Labora
