Abstract
In this work was evaluated the behavior of a wind power generation system connected to the electric grid using the permanent magnet synchronous generator (PMSG). The active and reactive powers are controlled by the machine side converter (MSC) in dq coordinates by the rotor magnetic flux orientation, and in the grid side converter (GSC) they are controlled in αβ coordinates through electric grid voltage. The active power filter (APF) is added to the GSC through an algorithm that allows to compensate the harmonic components present in the electric grid currents.The results were obtained using the computer simulation software Matlab / Simulink. Two case studies are analyzed to investigate the effectiveness of the control techniques employed, in which in case 1 the wind system operates only in the control of powers, and in case 2 the APF function is added to the GSC. The total demand distortion (TDD) of the grid current of 10.84 % (case 1) were decreased to 1.37 % (case 2) when the electric generator operates at its nominal conditions. Thus, the techniques used in the PMSG / APF set proved to be effective for generating wind power and improvement of power quality.
