Closing Time:
During this state the recloser sends a closing command and for this reason, if
you wish to associate an output to that command, the output must be set to the 79 Closing Time
bit.
It must be possible to block the recloser, specially is maintenance tasks are carried out on the substation.
To achieve this, there is two logical signals
79Block Command
and
79Unblock Command
where up
to 4 logical inputs can assigned to each one. By default, they are configured as follows:
79Block Command
79Unblock Command
Input
Logical Gate
Input
Logical Gate
Block Command USB COM
OR
Block Command USB COM
OR
Block Command HMI
Block Command HMI
Block Command Rear COM
Block Command Rear COM
So, it can be (un)blocked with the next options:
✓
From the HMI.
There are two specific keys marked 79 Block and Unblock, plus a specific signal
led, allowing recloser operation, blocking or unblocking it.
✓
From the HMI.
This command can be executed from the command menu.
✓
Via protocol.
This is performed via any means of communication. This is carried out as if it was
a command, and the normal conditions of any command must be met.
In all these cases, the equipment stores the block situation in the non-volatile memory, as the last
command must be known for a possible re-start.
The logic signal
Hot Line Tag
also affects the behaviour of this function. When it is activated, the
function is blocked, and reclosing is not permitted.
Also, this logic signal can be configured to change the Settings Groups through PGC. This can be useful
to achieve a fast tripping of protection functions in Hot Line Tag Mode.
The auto-recloser´s start up is shown in the following figure:
