【 摘 要 】

PI controller is very common in the control of DVRs. However, one disadvantage of this conventional controller is its inability to still working well under a wider range of operating conditions. So, as a solution fuzzy controller is proposed. This paper discusses the design and simulation of dynamic voltage restorer for improve power quality and reduce the harmonics distortion of sensitive load. Power quality problem is an occur as a non-standard voltage, current and frequency. Electronics devices are very sensitive load against harmonics. In power system voltage sag, swell, flicker and harmonics are some of the problem to the sensitive load. The compensation capability of a DVR depends primarily on the maximum voltage injection ability and the amount of stored energy available within the restorer. This device is connected in series with the distribution feeder at medium voltage. A fuzzy logic control is proposed. Simulation result carried out by Matlab/Simulink verifies the performance of the proposed method.
