Modeling, Simulation and Real Time Implementation of MPPT Based Field Oriented Control Applied to DFIG Wind Turbine

This paper aims to study the application of the maximal power point tracking (MPPT) to a variable speed wind turbine where a field-oriented control (FOC) is applied to the generator. Simulation in Matlab/Simulink environment is achieved first, then an experimental validation is conducted by means of a test bench containing a doubly-fed induction generator (DFIG) driven by a servomotor that emulates the behavior of the wind turbine, a back to back power converter and an RL filter. The implementation of the field-oriented control is realized using a digital signal processor (DSP) card and an acquisition interface.
