A megawatt scale test bed for power hardwarein-the-loop experimentation with high speed generators is described, and selected results from testing of a generator are presented. The test bed includes a dynamometer and high speed gearbox used to deliver up to 5 MW to the mechanical shaft of a generator at speeds of up to 24000 rpm. A rectifier using fast recovery diodes is used to rectify the vol...

The paper presents a new approach to the parameter identification of a wind turbine shaft vibrations measured with piezoelectric sensor. The system order and unknown processes matrices are determined using the wind force as the model input and wind turbine shaft vibrations as the model output. The identified model can be used to estimate the shaft vibrations and design an early damage monitorin...

This thesis deals with the modeling, analysis and control of a novel brushless generator for wind power application. The generator is named as rotating power electronic brushless doubly-fed induction machine/generator (RPEBDFIM/G). A great advantage of the RPE-BDFIG is that the slip power recovery is realized in a brushless manner. This is achieved by introducing an additional machine termed as...
