Resumen
This work presents a study of the impact of a new wind farm, in a particular system, of some converters for wind power generation with focus in the distortion of the voltage waveform in the system main bus. This document is developed through an introduction of some of the several existent topologies for wind power generation, as well the technologies of power converters applicable to each one of this configurations. It is also described the operation of these converters and the rule they have in this type of generation. After an explanation about the harmonics generated by a typical PWM converter applied to this kind of system, it is proposed and studied the behavior of a new wind farm operating in a weak grid. The voltage and current harmonic distortions are compared against the standards and current Brazilians grid code. With the obtained values can be observed that is needed the utilization of additional measures to guarantee the level of harmonic distortion within the required limits.
