Sensitivity assessment of PQ theory and synchronous detection identification methods of current harmonics under non-sinusoidal condition for shunt active filter

Abstract

This paper presents a comparative study between two commands of the shunt active filter under nonsinusoidal condition. In fact: 1) theory PQ. 2) Synchronous detection theory. The principal objective of this work is to test the sensitivity and robustness of the identification methods of the currents references, by calculating the THD. Interesting results are presented and analyzed below.
