ABB GOOSE Horizontal communication

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.

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.

Configuring horizontal communication

See detailed descriptions of the steps in corresponding chapters.

1. Add devices to a PCM600 project.

2. Export the SCD file.

3. Import the SCD file to IET600.

4. Engineer the GOOSE connections between the devices

4.1. Define the published GOOSE data and control blocks.

4.2. Define the subscribing IEDs for the GOOSE data.

5. Export the SCD file back to PCM600.

6. In PCM600. engineer the IED applications with GOOSE inputs.
