Abstract

An advanced control approach for power quality compensation using Unified Power Quality Conditioner (UPQC) is presented in this paper. This approach has capability of voltage distortion mitigation as well as current harmonics compensation. In the UPQC control, Series Active Filter (SAF) is controlled by d-q-o approach for voltage harmonic compensation. Voltage signal calculated at SAF is used for calculation of required reference signals using P-Q theory for Parallel Active Filter (PAF) control for current harmonic compensation. This control strategy requires reduced number of measurements (source voltage & load current). Simulation results show the validation of proposed method.
