Abstract :
The paper is focused on the presentation of the different theories of powers and current decomposition methods in the compensating current calculation for three-phase three-wire shunt active filtering systems. The decomposition methods are grouped into two categories, depending on the type of coordinate system used in the processing measurements involved in calculations. The former is based on the phase coordinates system and includes: the theory of Fryze, the theory of Fryze-Buchholz-Depenbrock, the so-called generalized theories of instantaneous reactive and non-active powers, the Currents´ Physical Components Theory (CPC) and the Conservative Power Theory (CPT). The latter refers to the orthogonal reference frame-based approaches such as the p-q theory and id-iq method. The applicability of each theoretical approach in the control of a shunt active power filter was analyzed. A summary highlighting the applicability under non-sinusoidal voltage and the main performance of each method is performed. Next, our platform for testing the control strategies of shunt power filters, based on DSP DS1103 system, is presented. An implementation on a dSpace 1103 DSP system of the theories presented above and some experimental results are given in the second part of the paper.
