ABB 650 series User Manual

selected depends on the status of the breakers and/or disconnectors. By checking
the status of the disconnectors auxiliary contacts, the right voltages for the
synchronizing, synchrocheck and energizing check functions can be selected.
Available voltage selection types are for single circuit breaker with double
busbars . Single circuit breaker with a single busbar do not need any voltage
selection function. Neither does a single circuit breaker with double busbars using
external voltage selection need any internal voltage selection.
The voltages from busbars and lines must be physically connected to the voltage
inputs in the IED and connected, using the PCM software, to each of the
SESRSYN functions available in the IED.
8.1.2.5 External fuse failure
M12322-3 v12
Either external fuse-failure signals or signals from a tripped fuse (or miniature
circuit breaker) are connected to HW binary inputs of the IED; these signals are
connected to inputs of SESRSYN function in the application configuration tool of
PCM600. The internal fuse failure supervision function can also be used if a three
phase voltage is present. The signal BLKU, from the internal fuse failure
supervision function, is then used and connected to the fuse supervision inputs of
the SESRSYN function block. In case of a fuse failure, the SESRSYN energizing
function is blocked.
The UB1OK/UB2OK and UB1FF/UB2FF inputs are related to the busbar voltage
and the ULN1OK/ULN2OK and ULN1FF/ULN2FF inputs are related to the line
voltage.
External selection of energizing direction
M12322-10 v8
The energizing can be selected by use of the available logic function blocks. Below
is an example where the choice of mode is done from a symbol ,created in the
Graphical Design Editor (GDE) tool on the local HMI, through selector switch
function block, but alternatively there can for example, be a physical selector
switch on the front of the panel which is connected to a binary to integer function
block (B16I).
If the PSTO input is used, connected to the Local-Remote switch on the local HMI,
the choice can also be from the station HMI system, typically ABB Microscada
through IEC 61850–8–1 communication.
The connection example for selection of the manual energizing mode is shown in
figure
33. Selected names are just examples but note that the symbol on the local
HMI can only show the active position of the virtual selector.
