【 摘 要 】

The increment of voltage – sensitive load equipment has made the industrial process must more susceptible to degradation in the power quality. Voltage deviation, often on the form of voltage sag, can cause severe process, result in economical loss. Among the Custom Power Device (CPD), the application of Dynamic Voltage Restorers (DVRs) in the distribution system is the recent invention. DVR’s are used to protect sensitive loads from the effects of voltage sags on the distribution feeder. DVR normally installed between the source voltage and critical or sensitive load. This paper describes DVR using Proportional Integral (PI) control technique. The simulations are performed using Matlab/Simulink’s SimPowersystem Toolbox.
