Nowadays, wind turbines based on a doubly fed induction generator (DFIG) are a commonly\nused solution in the wind industry. The standard converter topology used in these systems is the\nvoltage source inverter (VSI). The use of reverse-blocking insulated gate bipolar transistor (RB-IGBT)\nin the current source inverter topology (CSI), which is an alternative topology, opens new possibilities\nof control methods. This paper presents a novel power control system for a DFIG supplied by a CSI.\nThe authors propose to use multi-scalar DFIG state variables. A nonlinear control method realized by\nfeedback linearization was used to control the active and reactive powers of the generator. In the\nfeedback linearization controls, the nonlinear DFIG model was taken into account. In the control\nsystem structure, classical proportional-integral controllers were used. The control variables were\nthe output current vector components of the CSI. Such approach was named the â??current controlâ?.\nThe proposed control method is characterized by good dynamic properties which, combined with\nthe inverter properties in the rotor circuit, allow to increase the quality of the energy transferred\nto the grid by the generator. In the simulation tests, the correctness of the decoupling of the active\nand reactive power control loops, the dynamics of controlled power changes, and the change of the\nmachine operating range resulting from the increase of the rotational speed of the generator shaft\nwere controlled. The simulation studies also evaluated the impact of changes in the value of the\npassive elements of the system on the operation of the generator system. Characteristic operating\nstates of the generator system were analyzed using computer simulations.
