A diagnostic system for predicting wind turbine failure "before damage actually happens" has been developed in Germany by the Institut für Solare Energieversorgungstechnik (ISET) and Schenck Vibro of Darmstadt. The system combines expertise on turbine simulation with industrial microprocessor technology. "The mechanical vibrations of a turbine are continually analysed during operation and compared with those of a turbine operating perfectly. At the first signs of any deviations from the norm, the operator is automatically informed via modem and telephone," says Peter Caselitz from ISET. The development was supported by the federal research ministry and the Hesse environment ministry.
