Abstract

The growing expansion of wind power generation demands the verification of compliance with the grid operating requirements. In the current scenario, in the occurrence of a disturbance near the point of common coupling between the wind power plant and the electrical system, the wind turbines are required to remain in operation (a characteristic which is known as Fault Ride-Through (FRT)) and contribute to the control and stability of the electrical network. Despite having good functional characteristics, the DFIG wind turbines are machines sensitive to voltage sags, due to its constructive aspects. Thus, it has become necessary to implement methods to improve the dynamic behavior of these wind turbines in the occurrence of electrical network contingencies.. In this way, the present research project aims to verify two approaches, one based on an hardware and another on software approach, for the improvement of the FRT characteristic of grid-connected DFIG-based wind turbines. The steps of the project aim at a bibliographic review of the pertinent themes, implementation of a DFIG wind power plant connected to an electric network, implementation of a storage energy system to be connected to the wind power plant, application of an optimization method in the AC / DC / CA, and evaluation of the results. The present proposal is expected to contribute to studies and development of techniques for improving FRT capacity and, as a final consequence, to improve the energy quality and electrical system stability.
