Operation principle
The function sends information about the Permitted Source To Operate (PSTO) and
blocking conditions to other functions within the bay for example, switch control
functions and voltage control functions. The functionality of the Bay control
(QCBAY) function is mainly described by the LLN0 node in the IEC 61850-8-1
edition 2 standard, applied to one bay. In IEC 61850 edition 1 the functionality is
not described by the LLN0 node or any other node, therefore the Bay control
function is represented as a vendor specific node in edition 1.
Local panel switch
The local panel switch is a switch that defines the operator place selection. The
switch connected to this function can have three positions (remote/local/off). The
positions are here defined so that remote means that operation is allowed from
station and/or remote level and local means that operation is allowed from the IED
level. The local/remote switch is also on the control/protection IED itself, which
means that the position of the switch and its validity information are connected
internally, not via I/O boards. When the switch is mounted separately from the IED
the signals are connected to the function via I/O boards.
When the local panel switch (or LHMI selection, depending on the set source to
select this) is in Off position, all commands from remote and local level will be
ignored. If the position for the local/remote switch is not valid the PSTO output
will always be set to faulty state (3), which means no possibility to operate.
To adapt the signals from the local HMI or from an external local/remote switch,
the function blocks LOCREM and LOCREMCTRL are needed and connected to
QCBAY.
Permitted Source To Operate (PSTO)
The actual state of the operator place is presented by the value of the Permitted
Source To Operate, PSTO signal. The PSTO value is evaluated from the local/
remote switch position according to Table 96. In addition, there are two settings
and one command that affect the value of the PSTO signal.
If the setting AllPSTOValid is set to No Priority and the LR-switch position is in
Local or Remote state, the PSTO output is set to 5 (all), that is, it is permitted to
