Abstract: An increase of demand for electric energy results in a search for potential generation sources. The SIN (Brazilian interconnected electrical system) is expanding with the growth of its energy matrix mainly through renewable sources, as solar and wind generation. Those kind of sources configure an intermittent nature of generation and are typically linked to the grid using power electronics equipments. Also, they have intrinsics features that cause electromagnetic propagation phenomena in the extension of the grid where they are connected. Considering that scenario, the aim of this work is to evaluate wind turbines hold out in voltage sags situations, due to the occurrence of transmission grid short circuits. Plus, this work searches, as well, to carry out the study of the harmonic distortions caused by the wind generation to the Brazilian electric system. To develop this analysis, a case study is performed in a wind power plant located in the northeast of Brazil. Whole system is modeled using the ATPDraw and HarmZs softwares by equivalent models of the wind power plant. Voltage sag simulations applied showed up an existence of permission points for disconnecting the wind generators units in the first and second closer buses (closer substations), according to current Brazilian guidelines. As results, harmonic distortion simulations indicate that the performance of the wind power plant studied already presents an adequate individual harmonic distortion rate. Also, a future capacitor bank installation should reduce the harmonic distortion rate for a larger range of frequencies.
