Rezumat: Intr-un sistem de filtrare activa paralel, componenta circuitului de control care implementeaza strategia de compensare adoptata este blocul de generare a curentului de referinta, ce trebuie compensat. In aceasta lucrare, este prezentata o biblioteca Matlab/Simulink pentru generarea curentului de referinta in cazul compensarii totale si al celei partiale, bazata pe conceptele principalelor teorii ale puterilor in regim deformant. Aceasta este utilizata in implementarea sistemului de control pe o platforma experimentata dSPACE.

Abstract: In a shunt active filtering system, the component of the control circuit which implements the adopted compensation strategy is the reference compensating current generation block. This paper presents a Matlab/Simulink library for compensating current generation in case of both total and partial compensation, based on the concepts of the main theories of the powers under nonsinusoidal conditions. It is used in the implementation of the control system on an experimental dSPACE platform.

Keywords: active filters, modeling, software libraries, command and control systems
