KOMBINASI FEED BACK DAN FEED FORWARD KONTROLLER PI SEBAGAI KENDALI DYNAMIC VOLTAGE RESTORER (DVR) UNTUK MEMULIHKAN VOLTAGE SAG DAN INTERRUPTION
Abstract: Dynamic voltage
restorer (DVR) is one of equipments to protect sensitive load from voltage
drop. DVR is installed series with line feeder by serial transformer which
injecting voltage when under voltage occurs. This research is investigate the
capability of DVR, which controlled by combination of feed back and feed
forward PI, to handle voltage sag and interruption. DVR controls have been
designed and implemented in DVR prototype. As a result, in simulation, DVR can
maintain voltage in range 90% - 105% nominal voltage. Voltage at load side can
be restored to 1 pu and 0.79 pu when voltage sag and interruption respectively.
Furthermore, DVR prototype can restore 0.95 pu when voltage sag and 0.54 pu
when interruption.
