EVALUATION OF HARMONIC DETECTION METHODS FOR THREE-PHASE SHUNT ACTIVE POWER FILTER APPLICATIONS

Investigation of Harmonic Detection Techniques for Shunt Active Power Filter

Active power filters are used to eliminate current harmonics of non-linear loads. This paper evaluates three different methods of determining the compensating current for a shunt active filter that is working under nonsymmetrical conditions. The paper compares the instantaneous reactive power theory, the synchronous reference frame theory and fast Fourier transform techniques. The comparison is...
