Hello to u all,
I have questions regarding icd files related to SIEMENS devices and differences between this vendor and others (GE, SEL, ABB...etc).
Procedure that I have used for definition of GOOSE messages (sending/polling) worked nice between two SIPROTEC devices. i.e.
1) Allocate signals...
Of course - u can close CB. How could u energize S/S (bus bar) if u don't close breaker?
You can choose - if it is request of Grid department, than through Sync logic - close CB when:
DL-DB
DL-LB
LL-DB
LL-LB (volt, angle, freq condition - are in setting region)
(AND if no VT MCB trip...
It depends which dist. prot. u r using. Or should I say - according to manufact. specs. For Areva relays - it is defined by manufac., for Siemens relays - you can specify by software. ABB relays also - you can spec by means of software. So, just check the manual.
