Interline Dynamic Voltage Restorer (IDVR) is an optimum solution to compensate voltage sag in multiple lines. The IDVR consisting of two or more DVRs connected to different feeders in a power system sharing a common DC link energy. This paper presents the hardware implementation of novel bidirectional voltage sag compensation by the IDVR in multiple feeders at same instance.  A two line feeder power system with IDVR installed is considered. The IDVR is implemented using two VSI with filter. The control system of IDVR is developed using DSPACE 1103.
