Contribution to Wind Turbine Emulation Based on Wound Rotor Induction Machine Configuration
Résumé
This paper deals with a technique for emulation of wind turbine systems which are based on wound rotor induction machine technology using a reduced-scale test bench. The development of new control algorithms and fault diagnosis techniques is the main aim of this emulation with which the efficacy of these novel strategies can be evaluated in working conditions similar to those of full-scale wind turbines. The reduced-scale test bench has been designed according to the main components of a full-scale wind turbine system namely the main bearing, the main shaft, the planetary gearbox and the wound rotor induction machine. A rotor side converter is involved to manage both active and reactive power exchange with the power grid. Moreover, an external real-time data acquisition platform is utilized for data collection from different elements of the test bench. This has been realized using different kinds of measurement which are the outcome of accelerometer, torque, current and voltage sensors that will be used for studying the efficacy of various approaches of wind turbines' condition monitoring. The parameters of a full-scale 600kW wind turbine have been used and adapted to a reduced-scale test bench setup based on a 5.5kW wound rotor induction machine for the validation of the proposed method.
