Fuzzy neural technique based dynamic voltage restorer for power quality enhancement under different voltage variations

الملخص EN

Recently a large interest has been focused on power quality field due to: disturbances caused by non-linear loads, Increase in the number of electronic devices and renewable energy sources.

Power quality measures the fitness of the electric power transmitted from generation to the industrial, domestic and commercial consumers.

In a power system voltage distortion introduced by harmonics and voltage sags are the most severe affecting power quality, because of both consumers and utilities are affected by these disturbances.

Different methods to enhance the power quality but the custom power device is the most effective and efficient method.

One of which is the use of Dynamic Voltage Restorer (DVR).

The performance of the DVR based on Fuzzy Neural controller to restore the load voltage to its nominal value under different fault conditions and power disturbances is presented in this paper.

Simulation results are carried out using MATLAB/SIMULINK program.

The faults and disturbances are initiated at 0.8s and kept till Recently a large interest has been focused on power quality field due to: disturbances caused by non-linear loads, Increase in the number of electronic devices and renewable energy sources.
