Generator protection REG670
Version 2.2
IEDs in a safe way and to prevent double operation in a
bay, switchyard part, or complete substation.
Reservation input RESIN
The Reservation input (RESIN) function receives the
reservation information from other bays. The number of
instances is the same as the number of involved bays
(up to 60 instances are available).
Bay control QCBAY
The Bay control (QCBAY) function is used together with
Local remote and local remote control functions to
handle the selection of the operator place per bay.
QCBAY also provides blocking functions that can be
distributed to different apparatuses within the bay.
Proxy for signals from switching device via GOOSE
XLNPROXY
The proxy for signals from switching device via GOOSE
(XLNPROXY) gives an internal representation of the
position status and control response for a switch
modelled in a breaker IED. This representation is
identical to that of an SXCBR or SXSWI function.
GOOSE function block to receive a switching device
GOOSEXLNRCV
The GOOSE XLN Receive component is used to collect
information from another device's XCBR/XSWI logical
node sent over process bus via GOOSE. The GOOSE XLN
Receive component includes 12 different outputs (and
their respective channel valid bits) with defined names
to ease the 61850 mapping of the GOOSE signals in the
configuration process.
Local remote LOCREM/Local remote control
LOCREMCTRL
The signals from the local HMI or from an external local/
remote switch are connected via the function blocks
local remote (LOCREM) and local remote control
(LOCREMCTRL) to the Bay control (QCBAY) function
ControlMode in function block
block. The parameter
LOCREM is set to choose if the switch signals are
coming from the local HMI or from an external hardware
switch connected via binary inputs.
Tap changer position reading TCMYLTC and
TCLYLTC
On-load tap-changer position can be monitored on-line.
This can be done by either using BCD coded binary input
signals or alternatively via an mA input signal. The actual
tap-position can be used by the transformer or overall
differential protection function in order to enable more
sensitive pickup setting. This will in turn make
differential protection more sensitive for low level
internal faults such as winding turn-to-turn faults.

Logic rotating switch for function selection and
LHMI presentation SLGAPC
The logic rotating switch for function selection and
LHMI presentation (SLGAPC) (or the selector switch
function block) is used to get an enhanced selector
switch functionality compared to the one provided by a
hardware selector switch. Hardware selector switches
are used extensively by utilities, in order to have
different functions operating on pre-set values.
Hardware switches are however sources for
maintenance issues, lower system reliability and an
extended purchase portfolio. The selector switch
function eliminates all these problems.
Selector mini switch VSGAPC
The Selector mini switch (VSGAPC) function block is a
multipurpose function used for a variety of applications,
as a general purpose switch.
VSGAPC can be controlled from the menu, from a symbol
on the single line diagram (SLD) on the local HMI or from
Binary inputs.
Generic communication function for Double Point
indication DPGAPC
Generic communication function for Double Point
indication (DPGAPC) function block is used to send
double point position indications to other systems,
equipment or functions in the substation through IEC
61850-8-1 or other communication protocols. It is
especially intended to be used in the interlocking
station-wide logics.
Single point generic control 8 signals SPC8GAPC
The Single point generic control 8 signals (SPC8GAPC)
function block is a collection of 8 single point
commands that can be used for direct commands for
example reset of LEDs or putting IED in "ChangeLock"
state from remote. In this way, simple commands can be
sent directly to the IED outputs, without confirmation.
Confirmation (status) of the result of the commands is
supposed to be achieved by other means, such as binary
inputs and SPGAPC function blocks. The commands can
be pulsed or steady with a settable pulse time.
Automation bits, command function for DNP3.0
AUTOBITS
Automation bits function for DNP3 (AUTOBITS) is used
within PCM600 to get into the configuration of the
commands coming through the DNP3 protocol. The
AUTOBITS function plays the same role as functions
GOOSEBINRCV (for IEC 61850) and MULTICMDRCV (for
LON).
Single command, 16 inputs
The IEDs can receive commands either from a
substation automation system or from the local HMI.
