The content of this function is represented by the IEC 61850 definitions for the
logical nodes Circuit breaker (SXCBR) and Circuit switch (SXSWI) with
mandatory functionality.
12.3.1.4 Proxy for signals from switching device via GOOSE XLNPROXY
GUID-2DA1E47C-5A9A-4C53-8D60-7B1729EF6B90 v1
The purpose of the proxy for signals from switching device via GOOSE
(XLNPROXY) is to give the same internal representation of the position status and
control response for a switch modeled in a breaker IED as if represented by a
SXCBR or SXSWI function.
The command response functionality is dependent on the connection of the
execution information, XIN, from the SCSWI function controlling the represented
switch. Otherwise, the function only reflects the current status of the switch, such
as blocking, selection, position, operating capability and operation counter
.
Since different switches are represented differently on IEC 61850, the data that is
mandatory to model in IEC 61850 is mandatory inputs and the other useful data for
the command and status following is optional. To make it easy to choose which
data to use for the XLNPROXY function, their usage is controlled by the
connection of each data’s signal input and valid input. These connections are
usually from the GOOSEXLNRCV function (see Figure
78 and Figure 79).
