Abstract :
Power quality problems have received great attention nowadays because of their bad economical impacts on both utilities and customers. The current harmonics are the most common power quality problem, and the voltage sag is the most severe one. This paper introduces a new control algorithm based on wavelet transform for unified power quality conditioner (UPQC) to suppress current harmonics and voltage sags. The proposed control algorithm is verified by digital simulation results using PSCAD/EMTDC
