Researches of transition and quasi-steady state processes in a shunt active power filter

Abstract

One of the methods to improve the power quality in electric power networks is the use of active power filters. In the article, a method of analysis of transition and quasi-steady state processes in a shunt active three-phase power filter (SAPF) was presented. The analysis of electromagnetic processes was carried out on the basis of a mathematical description of the active filter. Structural models for the simulation of dynamic processes in the shunt active three-phase power filter were developed. The results of studies of dynamic states obtained for the SAPF with independent control and current control were shown. A study of the active filter was performed with the use of Matlab-Simulink program.
