Control strategies of selective harmonic current shunt active filter
چکیده
Abstract
This paper presents the possible calculation methodologies in orden to design a selective shunt active filter. For realizing to selective extraction of harmonic sequences the modulation - filter - demodulation technique is used. The fundamental equations of this method are established in the case of pq theory showing its equivalence with the SRF (Synchronus Reference Frame) method. In order to prove the proposed ways of calculation real non-periodic currents data with a great harmonic distortion of an arc furnace are used, with the good results achieve shows the ability of filtering in a selective and controlled way the undesired current harmonics.
