ABB REF542 series 1VCR007346 G0028 Function and configuration

Functions

REF542plus Multifunction Protection and Switchbay Control Unit integrates all the secondary functions in a single unit. This multifunctional unit also features a self monitoring function. All functions are designed as freely configurable software modules. Therefore, a wide range of operation requirements in MV stations can be met without any problems. The versatility of the software makes it possible to use the REF542plus on every switchboard independent on the specific application required.

Configuration

Each application for protection and control can easily be configured by software function modules, which make arbitrary definition of the following features as part of the secondary system possible:

LED's (meaning and colors) for local indication

Single Line diagram to show the status of switching devices

Protection schemes

Control schemes

Interlocking schemes

Automation sequences

All functions in the switchbay can be specified in collaboration with ABB. The result of the configuration is saved and delivered together with the switchboard to the users. By using the "FUnctional block" Programming LAnguage (FUPLA) the REF542plus Multifunction Protection and Switchbay Control Unit offers engineers, especially those who are not software experts, the opportunity of easily updating the operation and handling of the switchbay.

With REF542plus the user has the benefit of a secondary system that is fully integrated in a true programmable controller. This flexibility is very advantageous for defining control functions for automation sequences, which can, for example, include the interlocking of the switching devices, blocking the release of specific protection functions, as well as starting switching sequences.

REF542plus multifunctional unit provides a wide range of logical functions so that each required control schemes can be configured. The range of logical functions includes:

AND logic gate

NAND logi

c gate

OR logic gate

NOR logic gate

XOR logic gate

Bistable and monostable flip flop

Counters

Timers

Pulse generators

Memories

Similar to the free definition of the control scheme, each required protection scheme can be configured by the combination of the available protection function modules. For example, the following protection functions areavailable:

Definite time overcurrent protection

Inverse time overcurrent protection 

 Directional overcurrent protection

Under- or overvoltage protection

Distance protection

Differential protection for transformer and motor

Thermal protection for cable, transformer and motor

Reverse power protection

Synchronism check

Note

The specific software configuration of the required protection scheme can only be carried out in-house at ABB.

The protection scheme parameters can be changed via the HMI Control Unit without using a personal computer. Additional functions can be excuted with a personal computer running the configuration software and connected to the optical interface on the front of the HMI unit.  

These additional functions are:

Parameterization of the protection scheme,

Read-out of the current measurement values,

Read-out of the status of the binary inputs and outputs,

Read-out of the fault recorder and

Viewing of the FUPLA logic I/O states
