In a power system, faults are considered to be an abnormal electric current parameter. Numbers of factors are responsible for the fault occurrence in a distribution system. Thus, Power electronics and advanced control technologies can be used to addresses the power system faults in order to detect and interrupt different types of faults in the power system. Major problems dealt in this paper are the current harmonics caused by non-linear loads, and voltage quality is another aspect that will cause several sensitive electronic types of equipment malfunctioning. Distribution static compensator (DSTATCOM) is used to compensate current harmonics, connected in series with the network. In order to improve voltage quality, Dynamic Voltage Restorer (DVR) is a solution, is connected in series with the network. The combination of a DSTATCOM and two DVR one can obtain Generalized Unified Power Quality Conditioner (GUPQC). This paper presents modelling, analysis and simulation GUPQC with three bus/feeder system with non-linear and sensitive loads. Simulation results of GUPQC under different fault conditions are discussed in this paper. The simulation results of the GUQPC to compensate current harmonics and voltage quality improvement shows its performance.
