Exercise 1 Purpose This exercise will show you how to configure GOOSE messages on two different REX670 relays.
1.2
System Configuration In this exercise a 4 breakers system with two IEDs will be the starting point for the GOOSE configuration. The figure above shows the system configuration. Breaker 1 and 2 will be controlled by a RED670 relay and breakers 3 and 4 by a RET670 relay.
The following GOOSE messages will be required:
DocNo/Rev. 2
RET670 o
87T trip signal
o
Breaker failure initiate signal of Breaker 4
o
Breaker 3 and 4 position
RED670 o
Breaker failure initiate signal of Breaker 2
o
Breaker 1 and 2 position

Checking PCM configuration and creating an IET600 new project 1. Double check that GOOSEBINRCV and GOOSEINTLKRCV are included on the PCM configuration of the RET670 and RED670 relays. If they are not available on the configuration, you will need to add both of them in order to receive the GOOSE messages.

ABB Substation Automation Products Because this exercise only uses ABB relays, you can leave the default settings when you are exporting the SCD file. If you were using relays from different vendors on PCM, then you will need to uncheck Export Private Sections and Export it.
3. Open IET600.
4. Click on the IET icon on the top-left side on the IET window and select Manage Projects.

8. You can identify the IED if you select the IED tab and then select one of the IEDs. You will see the given name on PCM on the properties section.
1.4
Creating Datasets
The next step is to create datasets on the RET670. The first dataset will have the 87T trip signal. On this exercise, this signal will be simulated from the tripping logic block (SMPPTRC).

1. Click on Datasets and then right click anywhere on the area showed on the figure above. Select Insert new row.
2. Write a name to the first dataset and click OK. Notice that the dataset is under the LLN0 node.

3. Select the created dataset and look for the SMPPTRC function block. Every protection function will be in the LD0 node. You will need to add the quality and then the general trip output to this dataset. To add quality [ST] and general [ST]use the Append button. In the right side column you can see what has been added to the dataset.

The third and last dataset on the RET670 is the breaker position indication of breakers 3 and 4. These signals come from SCSWI function blocks.

4. Create a second GCB Data. Follow the steps above and add the dataset that has the breaker failure initiate signal of breaker 4.
5. Create a third and last GCB Data. It will send breaker 3 and 4 positions.
If you are using a particular Virtual Local Area Network (VLAN), you can set this up on the option showed above on the same GCB Data window. Same applies to the GOOSE priority. You can choose a high priority (7) is the message is of high importance. NOTE: In this exercise we will use the default settings.

Creating Datasets and GOOSE Control Blocks on the RED670 relay The same procedure will be done on the RED670 to create the datasets and the GCB Data as in 1.4 and 1.5. The only difference with the RET670 is that only breaker failure initiate signal of breaker 2 and breaker 1 and 2 breaker position will be sent through GOOSE messages. The following figures show what will be included on the RED670’s datasets.

Now we will need to create the GCB Data on the RED670. After creating them, you will have something like in the figure above.
1.7
Subscribing IEDs One of the final steps before exporting the configured file is to subscribe the IEDs to the GOOSE message that is of interest of to each relay. In this exercise, the RED670 will subscribe to all the messages created on the RET670. The same applies to the RET670. It will subscribe to all the messages sent by the RED670. 1. Select the RED670 on the IED section and then double click on the boxes that have the GOOSE messages sent by the RET670. You will see an “x” when the selection is done.

3. Export the SCD with the GOOSE configuration.
4. Right click over substation section and click on Import. You will need to import the SCD file already created on IET600. Note: It is important that you make a backup of your PCM project before importing the configured SCD file.

5. Leave the default options for this exercise when the importing window pops up. If you were communicating with relays from different manufacturers and you included them on your IET600 configuration, you will need to choose Replace unknown IED types with generic IEC 61850 object type.
After importing the configured SCD file onto PCM, you will have to enable some parameters settings.
6. Open Parameter Settings Tool. Look for IEC61850-8-1:1in the IED Configuration. In the Operation setting choose Enabled. It will enable GOOSE messages. In GOOSE setting, verify that the GOOSE messages are sent by OEM311_AB Ethernet rear card. Note: It is possible to send GOOSE messages by the front Ethernet port, but it does not have a high priority on the relay’s logic when sending GOOSE messages through it.

7. Under the Application Configuration section, look for GOOSEBINRCV:1. Enable it. This setting enables the GOOSEBINRCV block to receive GOOSE messages. Note: The name of the tab, GOOSE, could be different if you chose a different name for it when you added the GOOSEBINRCV block on PCM.
8. Repeat the step above for the GOOSEINTLKRCV.
9. Open the Signal Matrix Tool. Select the Goose Receive tab. Map the GOOSE messages to the GOOSEBINRCV and GOOSEINTLKRCV.
