The lectures are combined with exercises founded in real wind turbine measurements, calibration of sensors in the laboratory and recording of real-time data from a 500 kW wind turbine sited at Risø. The wind turbine is operational and equipped with a complete measurement system, which is available from DTU over the Internet, see www.winddata.com/nordtank/.* ^! `( t- o9 m) {1 Z, N7 B
