Description

REM543CM216AAA REM543 Machine Terminals

Product description

• Integrated machine terminals for the protection, control, measurement and supervision of small and medium size generators, synchronous motors and large asynchronous motors.
• Voltage and current measurement via conventional measuring transformers or current sensors and voltage dividers.
• Fixed man-machine interface including a large graphic display, or an external display module for flexible swichgear installation.
• Extended functionality including protection, control, measurement, condition monitoring and communication.
• Non-directional/directional overcurrent/earth-fault protection functions, over- /undervoltage protection functions and special functions for the protection of motors and generators, e.g. voltage controlled overcurrent protection, differential protection with several principles, underexcitation protection, underimpedance protection (line back-up prot.), thermal overload protection, protection again stunbalanced
load, abnormal frequency protection,  reverse or low-forward power protection and start-up supervision for motors.

• Control functions including local and remote control of switching objects with synchro-check, status indication of the switching objects and interlockings on bay and station level.
• Measurement of phase currents, phase-tophase and phase-to-neutral voltages, neutral current and residual voltage, frequency, power factor, active and reactive power and energy.
• Optional RTD/mA I/O-module for stator winding, bearing and ambient temperature monitoring. Analog mA outputs for interfacing with process control system.
• Condition monitoring including circuitbreaker condition monitoring, trip circuit supervision and internal self-supervision of the machine terminal.
• Communication over three communication interfaces: one for local communication with a PC and the others for remote communication with a substation control system or with a substation monitoring system.
• Part of the ABB’s Distribution Automation system.

REM543

Product parameter

The machine terminals REM 543 and REM 545 differ from each other in the number of digital inputs and outputs available. Please refer to the section “Ordering” for more details.
The REM 54_ machine terminals incorporate a wide range of functions:
• Protection functions
• Measurement functions
• Control functions
• Condition monitoring functions
• General functions
• Communication functions
• Standard functions
The function blocks are documented on the CD-ROM “Technical Descriptions of Functions” (1MRS 750889-MCD).

Application field

The REM 543 and REM 545 rotating machine terminals are designed to be used as an integrated main protection system of generator and generator-transformer units in small and medium-power diesel, hydroelectric and steam power plants, etc. The protection of large and/or important MV synchronous and asynchronous motors used e.g. in pumps, fans, mills and crushers during start-up and normal run forms another application area.
The REM 54_ machine terminals as integrated packages make possible compact marine environment solutions for unit protection, too.
In addition to protection, measurement, control and condition monitoring and general functions, the machine terminals are provided with a large amount of PLC functions allowing several automation and sequence logic functions needed for substation automation to be integrated into one unit. The data communication properties include SPA bus, LON bus or MODBUS communication with higher-level equipment. Further, LON interbay communication, together with PLC functions, minimizes the need for hardwiring between the machine terminals.

widely used in smart home, logistics management, environmental monitoring and other fields.
