The window of time during which the unblocking logic is enabled starts 10 ms after the guard
signal is lost, and continues for 150 ms. The 10 ms delay gives time for the signaling
equipment to change frequency as in normal operation. For the duration of any alarm
condition, zone 1 extension logic will be invoked if the option
Z1 Ext on Chan. Fail
has been
Enabled.
1.23.6
Distance scheme BLOCKING (Distance option only)
The signaling channel is keyed from operation of the reverse zone 4 elements of the relay. If
the remote relay has picked up in zone 2, then it will operate after the trip delay if no block is
received. Listed below are some of the main features/requirements for a BLOCKING
scheme:
BLOCKING schemes require only a simplex signaling channel
Reverse looking Zone 4 is used to send a blocking signal to the remote end to prevent
unwanted tripping
When a simplex channel is used, a BLOCKING scheme can easily be applied to a
multi-terminal line provided that outfeed does not occur for any internal faults
The blocking signal is transmitted over a healthy line, and so there are no problems
associated with power line carrier signaling equipment
BLOCKING schemes provides similar resistive coverage to the permissive overreach
schemes
Fast tripping will occur at a strong source line end, for faults along the protected line
section, even if there is weak or zero infeed at the other end of the protected line
If a line terminal is open, fast tripping will still occur for faults along the whole of the
protected line length
If the signaling channel fails to send a blocking signal during a fault, fast tripping will
occur for faults along the whole of the protected line, but also for some faults within the
next line section
If the signaling channel is taken out of service, the relay will operate in the conventional
basic mode
A current reversal guard timer is included in the signal send logic to prevent unwanted
trips of the relay on the healthy circuit, during current reversal situations on a parallel
circuit
Figure 40 shows the simplified scheme logic.
