This wind trainer is used to investigate the design and operation of modern wind power stations with double-fed induction generators. The effect of wind force and the mechanical design of wind power stations can be emulated in realistic detail using the servo machine testing stand and the WindSim software. The control unit for the double-feed asynchronous machine (as a generator for the wind power plant) ensures user-friendly operation and visualisation during the experiments. The corresponding Interactive Lab Assistant Multimedia course is designed to convey knowledge and provide interactive support for carrying out the experiments and allows for PC-assisted evaluation of the measured data.
