Simulation And Performance Investigation Of Series Active Power Filter Using Hysteresis Current Control Method

摘要

The simulation study of Hysteresis Current Controlled, three phase series active power filter to improve power quality b y co mpensating harmonics and reactive po wer required by a non -linear load is presented. The series active filter employs a simple method for the reference compensation voltage based on p-q theory. Classic filters may not have satisfactory performance in fast varying conditions. But auto tuned active power filters give better result for harmonic minimization, reactive power compensation and power factor improvement. This paper has proposed an auto tuned series active filter maintains the THD well within the IEEE-519 standards. The results are found to be quite satisfactory to mitigate harmonic distortion, reactive power co mpensation and power factor improvement
