Development of an experimental rig for doubly-fed induction generator based wind turbine

This paper deals with an experimental rig for a doubly-fed induction generator (DFIG) based wind turbine developed at the University Duisburg-Essen. The authors provide an overview of the dimensioning, commissioning and operation as well as show results of the measurements and compare these with simulation results. The main focus of the paper is the practical implementation and programming of the digital signal processor (DSP). Chapter one gives an introduction, followed by a brief explanation of the DFIG concept and its control in chapter two. Chapter three deals with the equipment of the experimental rig, and this is followed by the introduction of the rapid control prototyping approach chosen for programming the DSP. The paper ends with a comparison of the results of simulations with measurements and some concluding remarks.
