| Popis: | In this paper, a novel direct power control algorithm for a Doubly Fed Induction Generator-based wind system, robust to the machine parameters variations, is projected. The proposed scheme employs two loops designed using the discretized equations of the generator to obtain a high performance of the controller. Also, the rotor voltage vector is computed by the proposed strategy in order to guarantee the DFIG operation even during a symmetrical voltage sag on the power grid. The influence of the estimation errors for these parameters was also researched. The results obtained by computer simulations and by experimental setup corroborate the proposed controller performance. |
