Modeling and simulation of three-phase active filters

Summary from only given. Active filters are installed in parallel or in series with harmonic sources, combined with passive filters or integrated into unified power quality conditioners. Each configuration has its own advantages and limitations. Given the current status of electromagnetic transients programs, only an idealized representation of the power circuit of an active filter is possible. This is an important limitation for filter design; however, it allows users to analyze very accurately the interaction between the filter and the power system. This paper includes a complete case study with the application of an active filter for harmonic and reactive power compensation
