Total Number of Digital Substations in South Korea

Number of Digital Substation Installations

substation engineering tool called
S-CLICK (it sets up and verifies
communication and data exchange
between various IEDs and operating systems of a digital substation),
substation human-machine interface (HMI), IEC 61850 server/client conformance testing device, and
application software programs for
the substation automation system.
Several other items needed to be
developed, including protection and
control IEDs [e.g., protective relaying devices, on-load tap-changer
controllers, circuit breaker (CB)
controllers, capacitor bank switches, recloser controllers, voltage regulators, and shunt reactor switches],
power quality IEDs, a bay controller
(controlling a bay in a substation), a
merging unit (a device that enables
the implementation of IEC 61850 by
converting the analog signals from
the conventional current transformers and voltage transformers into
IEC 61850 sampled values), and a
generic object-oriented substation
event (GOOSE) messaging agent
(software that monitors and publishes GOOSE messages to test and
verify GOOSE messages of IEDs).
