The simulation study of hysteresis controlled three phase unified power quality conditioner (UPQC) to improve power quality by compensating harmonics and reactive power required by a non-linear load is presented. UPQC consists of back to back connected Series And Shunt Active Filters, and is modeled with reference to a synchronously rotating d-q-o reference axes. The shunt active power filter compensates the source current harmonics and also it maintains the dc link voltage unchanged in steady state, while the series active power filter compensates the load voltage harmonics. This paper has proposed auto tuned UPQC maintains the THD well within the IEEE-519 standards. The results are found to be quite satisfactory to mitigate harmonics distortion, reactive power compensation and power factor improvement.
