• Pole discrepancy supervision
• Operation counter
• Suppression of Mid position
The apparatus control function is realized by means of a number of function blocks
designated:
• Switch controller SCSWI
• Circuit breaker SXCBR
• Circuit switch SXSWI
• Bay control QCBAY
• Position evaluation POS_EVAL
• Bay reserve QCRSV
• Reservation input RESIN
• Local remote LOCREM
• Local remote control LOCREMCTRL
SCSWI, SXCBR, SXSWI and CBAY are logical nodes according to IEC 61850. The
signal flow between these function blocks appears in figure 233. To realize the
reservation function, the function blocks Reservation input (RESIN) and Bay reserve
(QCRSV) also are included in the apparatus control function. The application
description for all these functions can be found below. The function SCILO in the
figure below is the logical node for interlocking.
Control operation can be performed from the local IED HMI. If the administrator has
defined users with the UMT tool, then the local/remote switch is under authority
control. If not, the default (factory) user is the SuperUser that can perform control
operations from the local IED HMI without LogOn. The default position of the local/
remote switch is on remote.
