D-PRO Protection relay Technical Manual 27

The parameter P.0542 allows to choose whether to send the phase-to-phase voltages
measurements or the phase-to-neutral ones to the server.

The parameters P.0581 and P.0582 allows to set the fixed coordinates of device location
(latitude and longitude) in Google Maps format to be sent to the server. (e.g. the SICES
’s
coordinates are: Latitude 45.70907 and Longitude 8.80595, while the SICES
BRASIL’s
coordinates are: Latitude -23.499973 and Longitude -46.852907).
For further details on the
communication to the “Si.Mo.Ne” server, see the document [9].

6.1
The correct operation of the controller is guarantee by the led ON flashing.
The D-PRO protection relay, once the initial check has been carried out, starts to work
acquiring the measurements of the plant and checking the status of the protections configured.
In the standard configuration, the protections are always enabled (status ENABLE). It is
possible to disable them individually, during the configuration procedure, by setting the related
“Protection delay” parameter to zero.
Usually, when the measurement exceeds the threshold configured, the protection is enabled
(ACTIVE); if the condition remains stable for the time configured, the protection triggers
(TRIP); otherwise, the protection is restored.
6.2
The intervention of the single protection can be dynamically inhibited according to the status
of the plant conditions (by configuring the digital inputs properly). For example, this procedure
allows to enable the protection intervention only with genset running and circuit breaker closed.
If no disabling input is combined, the protection is considered always enabled.
The D-PRO protection relay can combine eight functions to the digital inputs:
•
DIF.2711
(”Protections disabling - Level 1”). The controller inhibits the intervention of
the protections configured in the parameter P.0201.
•
DIF.2712
(”Protections disabling - Level 2”). The controller inhibits the intervention of
the protections configured in the parameter P.0202.
•
DIF.2713
(”Protections disabling - Level 3”). The controller inhibits the intervention of
the protections configured in the parameter P.0203.
•
DIF.2714
(”Protections disabling - Level 4”). The controller inhibits the intervention of
the protections configured in the parameter P.0204.
•
DIF.2715
(”Protections disabling - Level 5”). The controller inhibits the intervention of
the protections configured in the parameter P.0205.
•
DIF.2716
(”Protections disabling - Level 6”). The controller inhibits the intervention of
the protections configured in the parameter P.0206.
•
DIF.2717
(”Protections disabling - Level 7”). The controller inhibits the intervention of
the protections configured in the parameter P.0207.
