Load current feedforward based control of doubly fed induction generator feeding nonlinear load

The paper presents the method of stator voltage control of the doubly fed induction machine based generation system feeding nonlinear load. The method uses load current signal as feedforward structure without the use of selective extraction of harmonics components. There are compared results with measured and estimated current of nonlinear and unbalanced load. The dynamic states of step loading and unloading are presented in the paper.
