Interline Dynamic Voltage Restorer (IDVR), voltage swell/sag, PID Controller technique.


IDVR is a device where more than two DVR connected in multi-transmission line. Performance of DVR is to inject the voltage to the line for long period voltage sag/swell. Generally, DVR in IDVR device compensates voltage sag/swell other DVRs connected in common DC link capacitor which replenish the energy and keep up the DC link at constant. Design, modeling, and performance of IDVR are proposed in this paper. IDVR consist of two different lines with two DVR devices to compensate the voltage sag. Series connected compensator (DVR) compensates sending end voltage disturbance voltage sag. In this paper, analyse the closed loop control of IDVR system is using PID controller and their output results are verified using MATLAB/Simulink.
