Load compensation for single phase system using series active filter

The exponentially rising application of power electronics based appliances in Domestic Consumer Voltage Distribution System (DCVDS) has enhanced power quality problems even at the lowest voltage level in distribution system. Starting from transmission system to low voltage distribution system, quite a good number of series active filters has been designed with a limited emphasis on single phase system as no imposition has been made by governing bodies/standards at international level. In this paper a new control strategy for series active filter has been proposed for improvement of power quality problems in single phase system. Since the non linear loads in the system comprises of both voltage source harmonic and current source harmonic loads and the dominancy of each type of load varies from time to time, the non linear load ranging from voltage source type harmonic load (VSHL) dominant to current source type harmonic load (CSHL) dominant has been taken up for study. The proposed series active filter has shown better power quality improvement even with variation of non linear load from voltage source harmonic load dominant to current source harmonic dominant. The power quality improvement has been shown through simulation results using EMTDC/PSCAD.
