PROTECTION DEVICE INTERFACE CEI 0-16
Monitoring system for photovoltaic system
The protection system interface (SPI) PMVF 30 has been designed according to the CEI 0-16, edition December 2012, and it is employed in the case of connection of a system of local generation in parallel to the medium voltage network of the distributor.
The checks cover limits on the voltage and frequency.
The SPI must take action de-energizing a relay output to the release of the device interface (DDI) in the case at least one of voltage and frequency appears outside the permitted limits.
PMVF 30 is equipped with inputs with the following
feedback status of DDI
exclusion interface protection
remote trip (forced opening of the DDI regardless of the values of voltage and frequency).
In addition, there are 2 relay outputs for:
opening of reinforcement device (programmable output: retentive normally energized, de-energized or normally retentive pulsed adjustable).
The command for the device of reinforcement is required for installations above 400kW and is constituted by a delayed signal of 1s compared to the opening command of the DDI, the DDI only sent if it fails sectioning.
Auxiliary voltage: 30 PMVF: 100 ... 250VDC 400VAC/110 ...
voltage inputs (insertion via TV): Primary: 50 ... 500.000V, secondary: 50 ... 500V
relay outputs 250VAC 5A (AC1) / 30VDC 5A
4 digital inputs
current inputs (optional): by CT / 5A or / 1A Selectable
support communication modules EXP ... by adding communication ports (USB, RS232, RS485, Ethernet, see page 4)
