Preprocessing blocks and fixed signals

The analog current and voltage signals coming to the IED are processed by
preprocessing blocks. There are two types of preprocessing blocks based on 20
samples per cycle and 80 samples per cycle. All function blocks functioning at 5 ms
task time need 80 samples per cycle whereas all the rest need 20 samples per cycle.
A fixed signal block providing a logical TRUE and a logical FALSE output has been
used. Outputs are connected internally to other functional blocks when needed.
Even if the AnalogInputType setting of a SMAI block is set to
"Current", the MinValFreqMeas setting is still visible. This means
that the minimum level for current amplitude is based on UBase. As
an example, if UBase is 20 kV, the minimum amplitude for current is
20000 × 10% = 2000 A.

Control functions

Motor bay control QCCBAY

Bay control is used to handle the selection of the operator place per bay. It provides
blocking functions that can be distributed to different apparatuses within the bay. Bay
control sends information about the permitted source to operate (PSTO) and blocking
conditions to other functions within the bay, for example switch control functions.

Apparatus control SCILO, GNRLCSWI, DAXCBR, DAXSWI

Apparatus control initializes and supervises proper selection and switches on primary
apparatus. Each apparatus requires interlocking function, switch control function and
apparatus functions.
