Supported ABB solutions

The REX640 protection relay together with the Substation

Management Unit COM600S constitutes a genuine IEC 61850

solution for reliable power distribution in utility and industrial

power systems. To facilitate the system engineering, ABB’s

relays are supplied with connectivity packages. The

connectivity packages include a compilation of software and

relay-specific information, including single-line diagram

templates and a full relay data model. The data model includes

event and parameter lists. With the connectivity packages, the

relays can be readily configured using PCM600 and integrated

with COM600S or the network control and management

system MicroSCADA Pro.

REX640 offers native support for IEC 61850 Edition 2 including

binary and analog horizontal GOOSE messaging. In addition, a

process bus enabling sending and receiving of sampled values

of analog currents and voltages is supported.

The Operator pages can be used as such or customized

according to the project’s requirements using Graphical Display

Editor (GDE) within the PCM600 software tool. The Engineer

pages are fixed and cannot be customized.

The Operator pages can be scrolled either by tapping the Home

button or by swiping the actual pages. The Engineer pages are

accessible by touching the upper horizontal section of the

screen.

The LHMI is an accessory for the relay which is fully operational

even without the LHMI. The relay communication card has a

dedicated port where the LHMI is connected using an RJ-45

connector and a CAT6 S/FTP cable. The LHMI can be

connected to the relay also via station communication network

if a longer distance is required between the relay and the LHMI.

Additionally, the LHMI contains one Ethernet service port with

an RJ-45 connector and one USB port. The service port can be

used for the PCM600 connection or for Web HMI connection.

Data transfer to a USB memory is enabled via the USB port. By

default the USB port is disabled and has to be taken into use

with a specific parameter.

Local HMI

The LHMI uses rugged 7-inch high resolution color screen with

capacitive touch sensing technology. The user interface has

been carefully designed to offer the best situational awareness

to the user. Visualization of the primary process measurements,

events, alarms and switching objects’ statuses makes the local

interaction with the relay extremely easy and self-evident. The

LHMI provides a control point for the selected primary devices

via pop-up operator dialogs.

Additionally, the LHMI supports the engineer during the relay’s

testing, commissioning and troubleshooting activities. The

information, traditionally accessible through different paths

within the menu structure, is provided in collectively grouped

and visualized format.

REX640 offers comprehensive base functionality. However, it is

possible to further adapt the product to meet special installation

needs by including any number of the available optional

application packages into a single REX640 relay. For the

selected application packages, the functionality can be

extended by including the related add-on package. The

REX640 connectivity package guides the engineer in optimizing

the application configuration and its performance.

Description

REX640 is a powerful all-in-one protection and control relay for

use in advanced power distribution and generation applications

with unmatched flexibility available during the complete life

cycle of the device – from ordering of the device, through

testing and commissioning to upgrading the functionality of the

modular software and hardware as application requirements change.

The modular design of both hardware and software elements

facilitates the coverage of any comprehensive protection

application requirement that may arise during the complete life

cycle of the relay and substation.

REX640 makes modification and upgrading easy and pushes

the limits of what can be achieved with a single device.

When IED configurations are changed using IET600. some preparations are

required when a project is started and the 615 series IED data model is imported to

the tool for the first time.

• The default 615 series IED SCL export from PCM600 contains five default

client definitions, “Client1”…”Client5”, which are used by all the RCBs.

MicroSCADA and COM600 clients can use the client definitions directly. If

other clients need to be added to the IET600 project, import the ICD file

describing the client data model to the project and attach the file to the same

IEC 61850 subnetwork in the Communication tab.

• Create the bus connections for the IEC 61850 clients.

All data sets must be configured under the logical node LLN0 and must be

provided with names unique within the IED. In 615 series IEDs there are a

maximum of four GOOSE control blocks allowed, which effectively limits the

relay to four data sets for GOOSE as there is a one-to-one correspondence between

the GOOSE control blocks and GOOSE data sets. Typically it is sufficient to

define a single data set and control block for an application. However, it is

recommended to use a separate data set and corresponding control block for analog values.

Importing a new IEC 61850 client

Adding a new IEC 61850 client to an IET600 project is a two-step operation. The

client must be first created using the Create New IED function, after which the

Update IED function can be used to import the related ICD (or CID) file.

1. To create an IED, click the IEDs tab in the navigation pane.

2. Click the root node in the IED tree.

3.Right-click the node and click Create New IED on the shortcut menu.

Creating a GOOSE data set

Define the sending data set used by the GOOSE control block. With the 615 series

IEDs, the sending GOOSE data set can have at maximum 20 data attributes to

minimize the message handling load in receiver and sending IEDs.

All data sets must be configured under the logical node LLN0 and must be

provided with names unique within the IED. In 615 series IEDs there are a

maximum of four GOOSE control blocks allowed, which effectively limits the

relay to four data sets for GOOSE as there is a one-to-one correspondence between

the GOOSE control blocks and GOOSE data sets. Typically it is sufficient to

define a single data set and control block for an application. However, it is

recommended to use a separate data set and corresponding control block for analog values.

A 615 series IED can send any type of status or measurand data in the GOOSE

messages from its IEC 61850 data model. The status data response time, that is, the

time it takes for the application to handle a received GOOSE message and to send

the concerned data back to the network, is with the 615 series IEDs below 3 ms.

The response time fulfils the tightest Type 1A, Class P2/3 requirements of the

standard.

When a 615 series IED is configured to send measurements, the analog, integer or

counter type of data should be placed on its own dataset. The triggering of analog

type of data sending is controlled by deadband handling, zero-point clamping and

limit supervision.

The horizontal communication configuration consists of the IEDs’ GOOSE control

block, data set and GOOSE input configuration. The result of the configuration

work is a system configuration file which can be downloaded to the IEDs. The

used files in the workflow are IEC 61850 standard format SCL files.

GOOSE is used in substation automation for fast horizontal communication

between the IEDs. GOOSE can be used for direct data exchange, for example, of

interlocking and blocking information between IEDs. According to the IEC

61850-8-1 standard, GOOSE uses a publisher/subscriber profile in which

information is shared from one IED to one or several IEDs by using Ethernet

multicast messages. A message is an image of a sent IEC 61850 data set that is

defined in the configuration.

IET600 is used to configure the vertical and horizontal communication properties

of the 615 series IEDs.

A 615 series IED can send any type of status or measurand data in the GOOSE

messages from its IEC 61850 data model. The status data response time, that is, the

time it takes for the application to handle a received GOOSE message and to send

the concerned data back to the network, is with the 615 series IEDs below 3 ms.

The response time fulfils the tightest Type 1A, Class P2/3 requirements of the

standard.
