Voltage Sag, Swell And Interruptions Compensation Based On Feed Forward Backpropagation Network Using Dynamic Voltage Restorer

Abstract

The widespread use of power electronics devices has led to a complete change in electrical load nature, all these variations in load causes disturbances in voltage waveforms. The disturbance includes Voltage sag/ swell, interruption etc. the use of custom power devices is considered to be the most efficient method for restoration of system voltage. Dynamic Voltage Restorer (DVR) can provide the cost effective solution for mitigation of short duration voltage disturbances in distribution system. Here in this paper, Three phase Dynamic voltage Restorer based on Neural Network controller with Levenberg- Marquardt Back propagation training algorithm are proposed for mitigating voltage sag, swell and interruptions. Short duration voltage disturbances are simulated on a three phase system and the comparative results has been presented using MATLAB/SIMULINK
