• The Switch controller (SCSWI) initializes all operations for one apparatus. It
is the command interface of the apparatus. It includes the position reporting as
well as the control of the position
• The Circuit breaker (SXCBR) is the process interface to the circuit breaker for
the apparatus control function.
• The Circuit switch (SXSWI) is the process interface to the disconnector or the
earthing switch for the apparatus control function.
• The Bay control (QCBAY) fulfils the bay-level functions for the apparatuses,
such as operator place selection and blockings for the complete bay.
• The Reservation (QCRSV) deals with the reservation function.
• The Protection trip logic (SMPPTRC) connects the "trip" outputs of one or
more protection functions to a common "trip" to be transmitted to SXCBR.
• 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 46
below.
