Local remote LOCREM/Local remote control
LOCREMCTRL
M17086-3 v11
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 block.
The parameter
ControlMode in function block 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.
Logic rotating switch for function selection and LHMI
presentation SLGAPC
SEMOD114908-4 v11
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
SEMOD158756-5 v10
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
SEMOD55850-5 v7
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
SEMOD176462-4 v11
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. The commands can be pulsed
or steady with a settable pulse time.
AutomationBits AUTOBITS
SEMOD158591-5 v9
The Automation bits function (AUTOBITS) is used to
configure the DNP3 protocol command handling. Each of
the 3 AUTOBITS available has 32 individual outputs
available, each can be mapped as a binary output point in
DNP3.
Single command, 16 inputs
M12446-6 v6
The IEDs can receive commands either from a substation
automation system or from the local HMI. The command
function block has outputs that can be used, for example, to
control high voltage apparatuses or for other user defined
functionality.
10. Scheme communication
Scheme communication logic for distance or
overcurrent protection ZCPSCH
M13860-3 v12
To achieve instantaneous fault clearance for all line faults,
scheme communication logic is provided. All types of
communication schemes for permissive underreaching,
permissive overreaching, blocking, delta based blocking,
unblocking and intertrip are available.
The built-in communication module (LDCM) can be used for
scheme communication signaling when included.
Current reversal and WEI logic for distance
protection, 3-phase
M13896-3 v15
The ZCRWPSCH function provides the current reversal and
weak end infeed logic functions that supplement the
standard scheme communication logic. It is not suitable for
standalone use as it requires inputs from the distance
protection functions and the scheme communications
function included within the terminal.
On detection of a current reversal, the current reversal logic
provides an output to block the sending of the teleprotection
signal to the remote end, and to block the permissive
tripping at the local end. This blocking condition is
maintained long enough to ensure that no unwanted
operation will occur as a result of the current reversal.
On verification of a weak end infeed condition, the weak
end infeed logic provides an output for sending the received
teleprotection signal back to the remote sending end and
other output(s) for local tripping. For terminals equipped for
single- and two-pole tripping, outputs for the faulted
phase(s) are provided. Undervoltage detectors are used to
detect the faulted phase(s).
Local acceleration logic ZCLCPSCH
M13823-3 v7
To achieve fast clearing of faults on the whole line, when no
communication channel is available, local acceleration logic
(ZCLCPSCH) can be used. This logic enables fast fault
clearing and re-closing during certain conditions, but
naturally, it can not fully replace a communication channel.
The logic can be controlled either by the autorecloser (zone
extension) or by the loss-of-load current (loss-of-load
acceleration).
