• 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 against unbalanced load, abnormal frequency protection, reverse or low-forward power protection and start-up supervision for motors.

• Condition monitoring including circuitbreaker condition monitoring, trip circuit supervision and internal self-supervision of the machine terminal.

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.

• 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 Substation Automation system.

Design

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).

Protection functions Protection is one of the most important functions of the REM 54_ machine terminal. The protection function blocks are independent of each other and have their own setting groups, data recording, etc. Typical current-based protection functions (e.g. overcurrent) can use either Rogowski coil or conventional current transformer measurement. Correspondingly, voltage-based functions (e.g. overvoltage) use either voltage dividers or voltage transformers.

The recordings can be ed with a DRCollector Tool which converts the data to a COMTRADE format. The DR-Collector Tool is ed in CAP501 and CAP505 relay tools.

Control functions The control functions are used to indicate the status of switching devices, i.e. circuit breakers and disconnectors, and to execute open and close commands for controllable switching devices of the switchgear. Furthermore, control functions provide on/off switching objects for control logic purposes and miscellaneous objects for data monitoring, etc. The control functions configured with the Relay Configuration Tool must be linked to object status indicators included in the MIMIC configuration picture displayed on the HMI. The object status indicators are used to indicate the status of switching devices via the MIMIC picture and to control them locally.

Condition monitoring functions

For further information about functionality levels and the protection functions included in them, refer to the table “Functionality levels, protection functions” in section “Ordering”.

Condition monitoring function blocks such as supervision of the energizing current and voltage input circuit, operation time counter, circuit-breaker electric wear, scheduled maintenance, trip circuit supervision and breaker travel time are available for the REM 54_ machine terminals.

Measurement functions

General functions

The measurement functions include threephase currents, neutral current, three-phase voltages, residual voltage, frequency, active and reactive power and power factor. An optional RTD/analogue module can be used for measuring stator winding, bearing, and ambient temperatures.

Disturbance recorder The transient disturbance recorder is able to record 16 current or voltage waveforms and 16 logic digital signals. The sampling frequency of the analogue inputs is 2 kHz at the rated frequency of 50 Hz and 2.4 kHz at the rated frequency of 60 Hz. 4

The can set the length of a recording within a range determined by the number of analogue inputs used. The number of recordings depends on the sampling frequency, length of recordings and number of analogue inputs.

Additional functions are available for different general purposes to be used in logics such as activation of HMI backlight, switchgroups, and resetting of operation indications, latched output signals, s and disturbance recorder.

Communication functions The machine terminal REM 54_ provides three serial communication protocols: SPA, LON and MODBUS.

Standard functions Standard functions are used for logics such as interlocking, alarming and control sequencing. The use of logic functions is not limited



Design (cont´d)

and the functions can be interconnected with protection, control, measurement, condition monitoring and other standard functions. In addition, digital inputs and outputs and LON inputs and outputs can be connected to standard functions by using the Relay Configuration Tool.

Other functions Low auxiliary voltage indication

The REM 54_ terminal is provided with a low auxiliary voltage indication feature. The power supply module issues an internal alarm signal when a drop in the power supply voltage is detected (ACFail, active low). The alarm signal is activated if the power supply voltage is about 10% below the lowest rated DC input voltage of the power supply module. The indication of a low auxiliary voltage is available in the machine terminal configuration and can be connected to any signal output of the REM 54_. Overtemperature indication

The REM 54_ machine terminal includes an internal temperature supervision function. The power supply module issues an internal alarm signal when overtemperature has been detected inside the terminal enclosure. The alarm signal will be activated once the temperature inside the terminal enclosure increases to +78°C (+75°C…+83°C). Overtemperature indication is available in the machine terminal configuration and can be connected to any signal output of the terminal. Analogue channels

The machine terminal measures the analogue signals needed for protection, measuring, etc. via sensors developed by ABB or galvanically separated matching transformers. Depending on whether sensors are included or not, REM 54_ machine terminals have 9 (without sensors) or 10 (with sensors) physical analogue channels. The number of channels used depends on the machine terminal configuration and the kind of matching transformers or sensor inputs used. Furthermore, the machine terminal includes virtual analogue channels for calculating the neutral current and residual voltage from phase currents and voltages. A current sensor (Rogowski coil) or a voltage divider can be connected to each sensor input.

Analogue channels of the machine terminal are configured with the CAP 505 Relay Product Engineering Tool. A separate scaling factor can be set for each analogue channel. The factors enable differences between the ratings of the protected unit and those of the measuring device (CTs, VTs etc.). The setting value 1.00 means that the rated value of the protected unit is exactly the same as that of the measuring device. • Machine terminals with the hardware number REM54x_xxxAAAA/CAAA/AAAB are configured for matching transformers • Machine terminals with the hardware number REM54x_xxx AABA/CABA/AABB are configured for matching transformers and sensor inputs Calculated analogue channels

The REM 54_ machine terminal includes virtual channels to obtain the neutral current and residual voltage when sensors are used. Current sensors and voltage dividers are connected to the machine terminal via coaxial cables and therefore a residual connection of the phase currents or an open-delta connection of the phase voltages cannot be made. Both the amplitude and the phase angle are calculated for the virtual channels. Though primarily meant to be used with sensors, the calculated analogue channels can also be used with conventional current and voltage transformers. Note! When sensitive earth-fault protection is needed, core balance transformers are not recommended to be replaced with the numerically derived sum of phase currents. Normally, an earth-fault setting below 10% of the rated value requires the use of a core balance transformer. Digital inputs

The digital inputs of the machine terminal are voltage-controlled and optically isolated. The function of a digital input can be inverted. The programmable filter time removes debounces and short disturbances on a digital input. The filter time is set for each digital input of the machine terminal. Some specific digital inputs can be programmed either as digital inputs or as pulse counters. When a digital input operates as a pulse counter, the frequency range of the input is 0…100 Hz. 5



Design (cont´d)

Oscillation suppression

The machine terminals have two global parameters for the suppression of digital input oscillation. The settings of these parameters determine the oscillation level and hysteresis for all digital inputs. An event is generated if oscillation is detected. Attributes of a digital input for machine terminal configuration

For each digital input the status of the input (value), the time tag for the status change (time) and the validity of the digital input (invalidity) can be issued by the attributes. These attributes are available in the machine terminal configuration and can be used for various purposes. Digital outputs

The digital outputs of the machine terminal are categorized as follows: • HSPO: High-speed power output, doublepole , preferred for tripping purposes and for circuit breaker and disconnector control • PO: Power output, either single-pole or double-pole , preferred for circuit breaker and disconnector control • SO: Signal output, either NO (Normally Open) or NO/NC (Normally Open/Normally Closed) . The output is a normal duty and cannot be used for controlling a heavy load such as a circuit breaker

Analogue outputs can be utilized for transferring any measured or calculated information to meters or e.g. PLCs. Alarm LED indicators

The machine terminal offers eight alarm LED indicators to be configured with the Relay Mimic Editor. The LED colours (green, yellow, red), their use and the ON and OFF state texts can be freely defined. Three basic operation modes are ed: non-latched, latched-steady and latched blinking. Alarms can be acknowledged remotely, locally and by using logic. The alarm channels include time tagging for detected alarms. The time tagging principle used depends on the operation mode. Interlocking LED indicator

The interlocking LED indicates that control operation has been interlocked or that the interlocking is in by mode, e.g. when control is possible despite of interlocking. Trip Circuit Supervision

The purpose of this function is to supervise the tripping circuitry of the circuit breaker. An alarm will be generated in case a faulty tripping circuit, e.g. a circuit is not able to perform a trip, is detected. The supervision is based on the constant-current injection through the tripping circuitry.

Display RTD/analogue inputs

The REM 543 and REM 545 machine terminals equipped with an RTD/analogue module (RTD1) have eight general purpose analogue inputs for DC measurement. The RTD/analogue inputs are galvanically isolated from the machine terminal power supply and enclosure. However, the inputs have a common ground. The general purpose RTD/analogue inputs accept voltage-, current- or resistance-type signals. For each measuring mode, a separate parameter is provided for choosing between the available measurement ranges. Analogue outputs

The REM 543 and REM 545 feeder terminals equipped with an RTD/analogue module have four general purpose 0...20 mA analogue current outputs. All outputs are galvanically isolated from the supply and enclosure of the machine terminal and from each other.

6

The machine terminal is provided with either a fixed display or an external display module. The external display module requires a separate voltage supply from a common source with the main unit. The display consists of 19 rows divided into two windows: a main window (17 rows) and an assisting window (2 rows). The graphic display presents detailed information on MIMIC, objects, events, measurements, control alarms, and parameters. The assisting window is used for terminal-dependent indications/alarms and help messages. Additionally, the includes the following HMI items: • three push-buttons for object control (I, O, object selection) • eight freely programmable alarm LEDs with different colours and modes according to the configuration



Design (cont´d)

• LED indicator for control test and interlocking • three protection LED indicators • HMI push-button section with four arrow buttons and buttons for clear and enter • optically isolated serial communication port • backlight and contrast control • freely programmable button (F) which can be used in the configuration of the machine terminal • a button for remote/local control The HMI has two main levels, the level and the technical level. The level is for “everyday” measurements and monitoring whereas the technical level is intended for advanced machine terminal programming.

Serial communication The machine terminal has three serial communication ports, one port on the front and two ports on the rear . The standard optical ABB connector

The standard optical ABB connector (RS-232 connection) on the front is intended for the connection of a PC for configuring the machine terminal with CAP 50_ tools. The front interface uses the SPA bus protocol. SPA/Modbus communication on the rear connector X3.2

The 9-pin D-type subminiature male connector (RS-232 connection) on the rear connects the machine terminal to the distribution automation system via the SPA bus or the Modbus. The fibre-optic interface module type RER 123 is used for connecting the machine terminal to the fibre-optic communication bus for SPA protocol. A third-party fully isolated RS-232/RS-485 converter1) is used for connecting the machine terminal to the RS-485 multi-drop communication bus for the Modbus. 1)

The port is not isolated. The functionality of the port is tested

machine terminal to the fibre-optic communication bus. The module RER 103 s both SPA bus and LON bus communication.

Self-supervision The machine terminal REM 54_ is provided with an extensive self-supervision system. The self-supervision system handles run-time fault situations and informs the of faults via the HMI and SPA/LON bus communication. When a fault has been detected, the green Ready indicator starts blinking and a fault indication text appears on the HMI. At the same time, the machine terminal delivers a fault signal to the self-supervision output relay and blocks the protection trip outputs. When an internal fault appears, the selfsupervision system generates an IRF code indicating the type of the fault. The fault code can be read from the machine terminal main menu.

Machine terminal configuration The Relay Configuration Tool, based on the IEC 61131-3 standard and included in the CAP 505 Relay Product Engineering Tools, is used for configuring the basic terminal, protection and logic function blocks, control and measurement functions, timers and other functional elements included in the logic functions category. The programmable system of REM 54_ machine terminals allows the output s to be operated in accordance with the state of the logic inputs and the outputs of the protection, control, measurement and condition monitoring functions. The PLC functions (e.g. interlocking and alarm logic) are programmed with Boolean functions, timers, counters, comparators and flip-flops. The program is written in the function block diagram language by using the configuration software.

with Phoenix RS-232/RS-485 converter (PSM-MERS232/RS485-P). In the delivery of the REM 543 with Modbus communication, a dedicated cable is included.

LON/SPA bus communication on the rear connector X3.3

The 9-pin D-type subminiature female connector (RS-485 connection) on the rear connects the machine terminal to the distribution automation system via the SPA bus or the LON bus. The fibre-optic interface module type RER 103 is used for connecting the

Mimic configuration with Relay Mimic Editor

The Relay Mimic Editor, included in the CAP 505 Relay Product Engineering Tools, is used for configuring the graphic display and the alarm channels of the machine terminal. The mimic configuration may include circuit breakers, disconnectors, indicators, measurement data objects and -defined texts and explanations. Any configuration can be saved for later use. 7



Design (cont´d)

All of the eight alarm function blocks can be configured in the same alarm view of the mimic editor. ON and OFF state texts (only one language version at the time can be ed for the alarm) and LED colours can be defined. Three different colours can be used to define the ON and OFF state. Three basic modes are available: • non-latched • latched-steady • latched blinking Interlocking LED texts can also be defined in the same alarm view but the colour of the interlocking LED cannot be changed. Lon network configuration

The Lon Network Tool is used for binding network variables between the machine terminal units. Typically, LON is used for transferring status data between units for interlocking sequences running in each machine terminal.

Machine terminal parameterization The parameters of the machine terminal units can be set either locally over the HMI or externally via the serial communication using the Relay Setting Tool CAP 501 or Substation Monitoring System SMS 510. Local parameterization

When the parameters are set locally, the setting parameters can be chosen from the hierarchical menu structure. The desired language for parameter description can be selected.

8

External parameterization

The Relay Setting Tool is used for parameterizing and setting the machine terminal externally. The parameters can be set off-line on a PC and ed to the machine terminal over a communication port. The menu structure of the setting tool, including views for parameterization and settings, is the same as the menu structure of the machine terminal.

Terminal connections All external circuits are connected to the terminal blocks on the rear . The terminal block for the measuring transformers consists of fixed screw terminals. ABB sensors (Rogowski coil or voltage divider) are connected to the machine terminal with a special type of shielded twin BNC connectors. This type of connectors are used to improve reliability and protection against disturbances. Unused sensor inputs must be short-circuited with special connectors, type 1MRS 120515. The digital input and output s of the machine terminal are connected to the multipole connectors. Protective earth is connected to the screw marked with the earth symbol.

Ordering

The following is to be specified when ordering REM 54_ machine terminals: order number, display language combination, quantity of machine terminals and possible Modbus option.

The order number is labelled on the marking strip on the front of the machine terminal delivered, e.g. Order No: REM543CM212AAAA.

Each REM 54_ machine terminal has a specific order number that identifies the machine terminal type as well as the hardware and the software as described in the figure below.

Ordering (cont´d)

Hardware versions of REM 543 and REM 545 For the number of digital inputs and outputs of REM 54_ machine terminals, refer to the tables above. The number of matching transformers, sensor inputs and analogue inputs and outputs, and the auxiliary voltage range vary between the different hardware versions of REM 54_. Moreover, both REM 543 and REM 545 can be supplied with an RTD/analogue module.

Software configuration Each REM 54_ machine terminal allows various software configurations based on separate functions. Functions included in the selected

52

functionality level can be activated within the scope of the I/O connections and considering the total U load of the functions.

Parts and assembly descriptions To achieve the best possible operation accuracy, all parts of REM 54_ have been calibrated together. Thus, each product forms a whole for which no separate spare parts can be supplied. In the event of malfunction, please consult your machine terminal supplier.
