| Popis: | The energy demand by modern society grows every day that allied with sustainable development requires the use of alternative sources in the new energy matrix. In this context, the wind energy as source by using a doubly-fed induction generator stands out due to its operational savings but still faces some conflicts in its power control. This paper proposes a state feedback plus integral controller for rotor current control. In order to verify the controller operation, an electromagnetic finite element analysis simulation of the interior of the machine was carried out, assuring the non-saturation of the core, which would lead to a control instability and it can increase the machine losses. For this, a machine modeling was presented into state equations in order to establish a power control diagram. The results of electromagnetic simulation and the experimental bench results when united ensure the correct functioning of the proposed system and the satisfactory efficiency of the controller. In this way, it can be concluded that the use of this control technique in counterpart with the conventional PI increases the response time of the system without affecting the electromagnetic dynamics of the generator. |
