• 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
• Bay reserve QCRSV
• Reservation input RESIN
• Local remote LOCREM
• Local remote control LOCREMCTRL
The signal flow between the function blocks is shown in Figure 140. 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.
When the circuit breaker or switch is located in a breaker IED, two more functions are added:
• GOOSE receive for switching device GOOSEXLNRCV
• Proxy for signals from switching device via GOOSE XLNPROXY
The extension of the signal flow and the usage of the GOOSE communication are shown in Figure 141.
