Abstract
Protection and substation control have
Under gone dramatic changes since the
advent of powerful micro-processing and
digital communication. Smart multi
functional and communicative feeder
units, so called IEDs(Intelligent
Electronic Devices) have replaced
traditional conglomerations of
mechanical and static panel
instrumentation. Combined protection,
monitoring and control devices and LAN
based integrated substation automation
systems are now state of the art.Modern
communication technologies including
the Internet are used for remote
monitoring, setting and retrieval of load
and faultdata. Higher performance at
lower cost hasresulted in a fast
acceptance of the new technology.
The trend of system integration will
continue, driven by the cost pressure of
competition and technological progress.
The ongoing development towards
totally integrated substations is expected
to pick up speed with the approval of the
open communication standard IEC61850
in the next years.
