Control DC link of single-phase dynamic voltage restorer

摘要: This paper is aimed to illustrate and expose the performance of single-phase voltage dynamic restorer (DVR) control connected electrical distribution grid. easily expressed by compensating for sags swells voltages, regulating across load injecting a component in series with source increased or decreased respect load-side waveforms are purely sinusoidal. The integration serial chopper converters makes DVR capable bidirectional power flow. key this topology its ability compensate sagging swelling long run. modeling design controller included document. Effectiveness systems start-up sequence operation verified detailed simulation studies. method used work based on use booster two cascade loops generate PWM command chopper. effectiveness suggested confirmed MATLAB/SIMULINK® results some prototype experiments. These show capacity proposed DC link control.
