Performances of a wind power system based on the doubly fed induction generator controlled by a multi-level inverter

The objective of this work is to study the contribution that use multi-level inverter can make compared a conventional two-level inverter, in wind power production line (WPG) associated with doubly fed induction generator (DFIG). DFIG driven by variable speed turbine and operates maximum point tracking (MPPT) mode, for optimum efficiency. rotor supplied DC/AC five levels MPC structure, controlled PWM technique, while stator connected network. active reactive powers exchanged between network achieved indirect vector control oriented flux (IFOC), regulators, ensuring zero unitary factor. total harmonic distortion (THD) current signals/voltages entire chain exposed criticized. obtained results are very promising, offering possibility turbines high voltage large power.
