Bay control REC670 2.2
Product version: 2.2.1

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
LOCREM and LOCREMCTRL to the Bay control QCBAY
function 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.

Voltage control TR1ATCC/TR8ATCC , TCMYLTC/TCLYLTC

Automatic voltage control for tap changer, single control
(TR1ATCC), Automatic voltage control for tap changer,
parallel control (TR8ATCC), Tap changer control and
supervision, 6 binary inputs (TCMYLTC) and Tap changer
control and supervision, 32 binary inputs (TCLYLTC) are used
for control of power transformers with an on-load tap
changer. The functions provide automatic regulation of the
voltage on the secondary side of transformers or alternatively
on a load point further out in the network.
Control of a single transformer, as well as control of up to
eight transformers in parallel is possible. For parallel control of
power transformers, three alternative methods are available:
the master-follower method, the circulating current method
and the reverse reactance method. The first two methods
require exchange of information between the parallel
transformers and this is provided for within IEC 61850-8-1.

M5864-3 v12
Voltage control includes many extra features such as the
possibility to avoid simultaneous tapping of parallel
transformers, hot stand by regulation of a transformer in a
group which regulates it to a correct tap position even though
the LV CB is open, compensation for a possible capacitor
bank on the LV side bay of a transformer, extensive tap
changer monitoring including contact wear and hunting
detection, monitoring of the power flow in the transformer so
that, for example, the voltage control can be blocked if the
power reverses, etc.
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
