INTRODUCTION
The PMVF 60 equipment has been designed as an Interface Protection (IP) in accordance with the SHAMS DUBAI - DRRG Standards Version 2.0 Dubai Electricity & Water Authority.
It can be applied to all LV and MV micro-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 switch (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 60 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 the SHAMS DUBAI - DRRG STANDARDS VERSION 2.0
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.
DESCRIPTION
–
Modular construction for DIN rail, 6 units.
–
LCD graphic 128x80 pixel, backlit, 4 grey levels.
–
4 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 (default).
•
Three-phase with neutral, VL-N voltage controls.
•
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 (auxiliary closure indication contact).
•
INP2: Remote frequency threshold selection input (external signal).
•
INP3: Interface protection disabling signal.
•
INP4: Remote tripping control input.
–
Optional power imbalance limit (LSP) threshold control.
–
Settings lock via 2-level changeable password.
–
Optional additional measurements, via connection of external CTs:
•
Currents.
•
Powers.
•
Energies supplied.
–
Set up for future installation of Interface module.
–
Optional power imbalance limit (LSP) threshold control in two possible modes:
•
IS trip (OUT1) when LSP exceeded.
•
Separate output switching (OUT3) on additional expansion module for LSP trip indication.
–
Programmable multifunctional output (OUT4) on additional expansion module.
TRIP THRESHOLDS
