The Selector mini switch VSGGIO function block is a multipurpose function used for a variety of applications, as a general purpose switch.
VSGGIO can be controlled from the menu or from a symbol on the single line diagram (SLD) on the local HMI.
IEC 61850 generic communication I/O functions DPGGIO
The IEC 61850 generic communication I/O functions (DPGGIO) function block is used to send double indications to other systems or equipment in the substation. It is especially used in the interlocking and reservation station-wide logics.
Single point generic control 8 signals SPC8GGIO
The Single point generic control 8 signals (SPC8GGIO) function block is a collection of 8 single point commands, designed to bring in commands from REMOTE (SCADA) to those parts of the logic configuration that do not need extensive command receiving functionality (for example, SCSWI). 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 SPGGIO function blocks. The commands can be pulsed or steady.
AutomationBits, command function for DNP3.0 AUTOBITS
AutomationBits 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 signals
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.
Scheme communication
Scheme communication logic for distance or overcurrent protection ZCPSCH
To achieve instantaneous fault clearance for all line faults, scheme communication logic is provided. All types of communication schemes for example, permissive underreaching, permissive overreaching, blocking, unblocking, intertrip are available.
The built-in communication module (LDCM) can be used for scheme communication signaling when included.
Phase segregated scheme communication logic for distance protection ZC1PPSCH
Communication between line ends is used to achieve fault clearance for all faults on a power line. All possible types of communication schemes for example, permissive underreach,permissive overreach and blocking schemes are available. To manage problems with simultaneous faults on parallel power lines phase segregated communication is needed. This will then replace the standard Scheme communication logic for distance or Overcurrent protection (ZCPSCH) on important lines where three communication channels (in each subsystem) are available for the distance protection communication.
The main purpose of the Phase segregated scheme communication logic for distance protection (ZC1PPSCH) function is to supplement the distance protection function such that:
• fast clearance of faults is also achieved at the line end for which the faults are on the part of the line not covered by its underreaching zone.
• correct phase selection can be maintained to support single-pole tripping for faults occurring anywhere on the entire length of a double circuit line.
To accomplish this, three separate communication channels, that is, one per phase, each capable of transmitting a signal in each direction is required.
ZC1PPSCH can be completed with the current reversal and WEI logic for phase segregated communication, when found necessary in Blocking and Permissive overreaching schemes.
Current reversal and weak-end infeed logic for distance protection ZCRWPSCH
The current reversal function is used to prevent unwanted operations due to current reversal when using permissive overreach protection schemes in application with parallel lines when the overreach from the two ends overlap on the parallel line.
The weak-end infeed logic is used in cases where the apparent power behind the protection can be too low to activate the distance protection function. When activated, received carrier signal together with local undervoltage criteria and no reverse zone operation gives an instantaneous trip. The received signal is also echoed back during 200 ms to accelerate the sending end.
Three phase or phase segregated scheme logic is available.
Current reversal and weak-end infeed logic for phase segregated communication ZC1WPSCH
Current reversal and weak-end infeed logic for phase segregated communication (ZC1WPSCH) function is used to prevent unwanted operations due to current reversal when using permissive overreach protection schemes in application with parallel lines when the overreach from the two ends overlaps on the parallel line.
The weak-end infeed logic is used in cases where the apparent power behind the protection can be too low to activate the distance protection function. When activated,received carrier signal together with local under voltage criteria and no reverse zone operation gives an instantaneous trip. The received signal is also echoed back to accelerate the sending end.
