• The Autorecloser (SMBRREC) consists of the facilities to automatically close a tripped
breaker with respect to a number of configurable conditions.
• The logical node Interlocking (SCILO) provides the information to SCSWI whether it is
permitted to operate due to the switchyard topology. The interlocking conditions are
evaluated with separate logic and connected to SCILO .
• The Synchrocheck, energizing check, and synchronizing (SESRSYN) calculates and
compares the voltage phasor difference from both sides of an open breaker with
predefined switching conditions (synchrocheck). Also the case that one side is dead
(energizing-check) is included.
• The Generic Automatic Process Control function, GAPC, handles generic commands from
the operator to the system.
The overview of the interaction between these functions is shown in Figure
