CHAPTER 3: IEC 61850 COMMUNICATION
Description
87L DIFF PFLL FAIL operand, which
becomes on when the differential
element's phase and frequency lock loop
(PFLL) has failed.
87L DIFF CH ASYM DET operand, which
becomes on when the differential
element's has detected substantial
communications channel asymmetry.
87L DIFF CH ζ FAIL operand, which
becomes on when the differential
element's has detected communications
channel ζ failed.
87L DIFF CHζ LOSTPKT operand, which
becomes on when the differential
element's has detected the lost packet
threshold has been exceeded on channel
ζ.
87L DIFF CHζ CRCFAIL operand, which
becomes on when the differential
element's has detected the CRC error
threshold has been exceeded on channel
ζ.
87L DIFF CHζ ID FAIL operand, which
becomes on when the differential
element's ID check for a peer L90 on
channel ζ has failed.
87L DIFF GPS FAIL operand, which
becomes on when the GPS signal failed
or is not configured properly at any
terminal.
87L DIFF CHζ MAX ASYM operand, which
becomes on when the Asymmetry on
channel ζ exceeded preset value.
87L DIFF CHζ TIME CHNG operand, which
becomes on when the Change in round
trip delay on channel ζ exceeded preset
value.
87L DIFF GPS ζ FAIL operand.
87L DIFF BLOCKED operand, which
becomes On when the 87L function is
blocked due to communication problems.
only instantiated in L90
50DD SV operand, which becomes On
when the 87L disturbance detector has
operated.
STUB BUS OP operand, which becomes
On when the Stub Bus function is active.
