IINTRODUCTION
The PMVF 80 equipment has been designed as an Interface Protection (IP) in accordance with VDE-AR-N 4105 and VDE V 0126-1-1 application guide. It can be applied to all LV generation systems (photovoltaic,
wind) where it is used to control the interface switch between generation system and public grid.
In the event of problems on the grid (e.g. due to maintenance), the system trips by opening the Interface switch (e.g. contactor) and isolating the generation system. In the event of Interface S witch (IS) failure, it can
also control a backup device to disconnect the generation system in any case.
The equipment features 4 digital inputs permitting the connection of the system to the signals provided by the network operator to meet the requirements of the current regulations. The functions implemented and the
possibility of further expansion ensure that it is prepared for any developments to the protection system.
The PMVF 80 equipment is supplied already programmed and assembled. With the factory settings, once the connections have been made, it is ready for operation in compliance with the requirements of
VDE-AR-N 4105 application guide without requiring any further settings to be made. It is nevertheless prepared for any future changes to the operating parameters.
Changes to the settings are password protected, preventing tampering by unauthorised personnel. In case of damage or malfunctioning the device shall be returned to LOVATO Electric.
DESCRIPTION
– Modular construction for DIN rail, 6 units.
– LCD graphic 128x80 pixel, backlit, 4 grey levels.
– Display and setting buttons.
– Voltage measuring inputs three-phase + neutral.
– Possibility of operation in the following line configurations:
• Three-phase with neutral, VL-L voltage controls;
• Three-phase with neutral, VL-N voltage controls;
• Three-phase with neutral, VL-N + VL-L voltage controls (default);
• Three-phase without neutral, VL-L voltage controls;
• Single-phase, VL-N voltage control.
– 2 switching relay outputs to control:
• OUT1: IS (Interface Switch) coil control;
• OUT2: backup device control.
– 4 contact digital inputs for:
• INP1: IS feedback input;
• INP2: R.O.C.O.F and Vector Shift monitoring function inhibition;
• INP3: interface protection disabling signal;
• INP4: remote tripping control input.
– Optional power unbalance limit (LSP) threshold control (current transformers required).
Two possible modes:
• IS trip (OUT1) when LSP exceeded;
• Separate output switching (OUT3) on additional expansion module for LSP trip indication.
– Settings lock via 2-level changeable password.
– Optional additional measurements, via connection of external CTs:
• Currents;
• Powers;
• Energies supplied.
– Setup for future installation of Interface module.
– Programmable multifunctional output (OUT4) on additional expansion module.
TRIP THRESHOLDS
– The voltage and frequency trip thresholds for which the equipment is set up according to the factory defaults are listed below. They correspond to the default requirements of VDE-AR-N 4105 application guide.
PMVF 80 can be set to P
≤
50kW or P>50kW cases by specific commands available in the command menu.
