MiCOM Relays Configuration Notes [PDF]

Zitiervorschau

Use the MiCOM S1 Studio software to configure the MiCOM relays for IEC 61850 communications. First we will use the MiCOM Data Model Manager to download device files off the Internet for a MiCOM Relay. In this example we will use a P443 relay. 1. Launch Data Model Manager.

Select “Add” from this window, and click the Next button.

Select the Source to be “Internet” and click the Next button. The next window that appears will show the Data Model Manager going out to retrieve all possible relay settings. You will then be asked to choose a language. The following window will appear showing the possible models to choose from.

Drill down into the “Px40/K/L/Px20(Courier) folder, and click on the checkbox for P443, and then click the Install button. This will download and install the necessary files on your PC to build a P443 relay device in MiCOM S1 Studio.

2. Create a new system and add a relay to the system.

Click on the “New System” icon, and enter in a name for the system (for example: TestP443).

Click on the New Device icon in the toolbar under Studio Explorer, or right click on the System that you created and select New Device. You will be prompted to select a device series, and for this example we will be creating a P443 relay, so we will select Px40 series.

You will be prompted to enter the model number for the specific relay, and in this example we will use a P44321AV7N0B00K.

You will be prompted to enter a name for the device, and in this example we will use P443.

Once this is complete a directory will be created for your new device.

3.

Add a setting file for the relay. Right click on the Settings folder and select New File. This will create a file “000” under the Settings folder. Double click on the “000” file. Double click on the System Data folder.

Here we will change the Frequency to 60Hz, by click on the row that says Frequency and a popup will appear asking you to enter in a new value.

When you click OK on the popup, you will see a Flag by Frequency and the text has been changed to RED. This is to denote a change in that particular setting, and that the setting must be saved by clicking on the “Save” button.

Double click on the CB CONTROL folder.

Here we will change how the Circuit Breaker is controlled. Double click on the “CB Control by” row, and a popup will appear asking you to change the setting.

We will change the setting to “Local+Remote”, which will allow the Breaker to be operated using PSE and the Front Panel pushbuttons.

We will also change the Circuit Breaker status setting. Double click on the “CB Status Input” row, and a popup will appear asking you to change the setting.

We will change the setting to “52A 3 pole”, which means the relay is monitoring a 3 pole circuit breaker using a single Form A contact input to the relay. Double click on the CT AND VT RATIOS folder.

Here we will change the VT and CT ratios for the relay. This information is typically found in the switchgear drawings. Double click on the row for “Main VT Primary”, and enter in a value of 7960. This will be a Line-Neutral voltage, and this is an example for a 13.8kV system (Primary=13800V : Secondary=120V).

Double click on the row for the “Main VT Sec’y”, and enter in a value of 120.

Double click on the row for the “Phase CT Primary”, and enter in a value of 600. In this example we will configure a 600A Feeder (Primary=600A : Secondary=5A).

Double click on the row for the “Phase CT Sec’y”, and enter in a value of 5.

Double click on the “OPTO CONFIG” folder.

Here we will change the logic level for the voltage for the contact inputs. Double click on the “Global Nominal V” row, and change the setting to 24/27V.

4. Next we will add a logic file to allow control and feedback of a Breaker connected to the MiCOM relay. Right click on the PSL folder and select New File. This will create a file “000” under the PSL folder. Double click on the “000” file. This will open a new window called PSL Courier.

Let’s zoom into the Opto Input Mappings, which is found on the upper left hand corner of the sheet.

This is where we can configure one of the status inputs to represent the Breaker status (Open/Close). In this example we will choose Input L9, and configure it for a 52-A 3pole contact. Input L9 is already configured for the Output Signal CB Aux A (52-B), but we will delete the Output Signal. Input L9 would be found on the back of the MiCOM relay as a digital input.

Next we will place an Output Signal, which can be found on the top toolbar, and place one next to Input L9.

Once you place the Output Signal on the sheet, you will be prompted with a Signal List.

Here we will choose the Output “CB Aux 3ph(52-A).”

Next we will link the Input L9 to CB Aux 3ph(52-A) output by using the Link button found on the top toolbar.

The final connection should look like the following:

Now if we move the sheet to the right we can view the Output Contacts for the MiCOM relay.

Here we see that Input Signal “Control Close” is linked to Output Contact R7 of the MiCOM relay, and that Input Signal “Control Trip” is linked to the Output Contact R8 of the MiCOM relay. This means that any Open command, either from SCADA or the MiCOM front panel will operate Relay 8 of the MiCOM relay to OPEN the breaker, and any Close command, either from SCADA or the MiCOM front panel will operate Relay 7 of the MiCOM relay to CLOSE the breaker. We will not make any changes to this logic, and will save the file and close the PSL Courier. 5. Add a MCL file for the relay for IEC61850 communications. Right click on the MCL 61850 folder and select New File. This will create a file “000” under the MCL 61850 folder. Double click on

the “000” file.

The IEC61850 IED Configurator will appear. Click on the Enter Manual Editing Mode button (Lock Symbol) found on the top toolbar.

Expand the Template listing found on the left hand pane.

Click on IED Details to configure the IED name.

For this example we will use the IED name P443.

Click on Communications on the left hand pane.

This is where you specify the IP Address of the MiCOM relay, and if the communications interface is Fiber or Copper.

Next click on Dataset Definitions on the left hand pane.

Here we will create a Dataset to include the data points that are required by SCADA. Click on the “Add Dataset” button.

You will need to create the Dataset in the System/LLN0 location, as this location is reserved for user configured datasets. Click on the “Set” button to continue.

Click on the “+” button to add data points to your dataset. In this example we will add the following points: Phase to Phase Voltage, Total Real Power, Total Reactive Power, Total Apparent Power, Total Power Factor, Frequency, Per Phase Amps, and the Breaker Status.

Next click on the Report Control Blocks on the left hand pane.

In this example we will configure Buffered Report A. Double click on System\LLN0\brcbA in the Report Control Blocks Summary window.

This is where you associate the custom dataset that you created earlier to a buffered report. Use the drop down box found under Dataset Reference, and select your dataset (P443System/LLN0$Dataset1 in this example).

Click on Controls in the left hand pane.

Here we will need to change the configuration of the XCBR node to allow for Control by the SCADA, as by default it is setup only for status. In this example we will modify the Control\XCBR1\Pos for status and control by double clicking on that entry in the Controls Summary window.

Use the drop down box found next to ctlModel, and select “direct-with-normal-security”, which allows for a Direct Operate command from SCADA.

Click on Measurements found in the left hand pane.

In the Measurements Summary window, you can enter the percentage change in terms of the primary values before a change gets reported by the relay. In this example we will look at the Phase to Phase Voltage (A-B).

The example shows that if you enter in a maximum value of 7960Volts, a change of 79.6V must occur before a change gets reported by the relay. Click on the save button, and then the validate button (green check mark), both which can be found on the top toolbar. When you click on the Validate button, the IED Configurator checks the settings of the MCL file that you created, and will show any Errors or Warnings, which you want to avoid. Close the IEC61850 IED Configurator window. 6. Create a connection to download all the settings that you created to the MiCOM relay. Right click on the Connections folder, and select New Connection. A popup window will appear.

In this example, we will use the MiCOM’s front serial port to send the settings to the relay.

This popup window is for you to choose what COM port to use on your PC to transfer the settings to the relay.

This popup window is where you will give a name for the connection between your PC and the MiCOM relay. In this example we will call it Front Port Serial. You can also uncheck the box for “Show me the Edit Communication Setup now”.

Right click on the Device (Device P443 in this example) and select Send. When you do this, the MiCOM S1 Studio will first check the connection to the relay to verify good communications between the PC and the relay. Then you will be prompted with a popup window.

Here we will select the following files to send: 000.set, 000.mcl and select Make Configuration Active, and 000.psl and select Group 1.

Click on the Send button to download the files to the relay. You will see an Operation Log window that will show the progress of all the different files that you’ve chosen to download to the relay. 7. Create a CID file to be used by the SCADA. Under the MCL folder, right click on the “000” file, and select Export SCL File.

In this example we will create a CID file called MiCOM_P443. 8. Modify the trigger options for the Report Control Blocks for the CID file. If we navigate in the CID file to the ReportControl name =”brcbA”, we will find the Buffered Report that we configured earlier in the example.

Notice that the TrgOps for period=”true”, which means the relay is setup to send out a Buffered Report on a periodic basis, regardless if any points have changed. We want to change that parameter to false.

Save the modified CID file. 9. After you created a Device Profile, and export the device to your Project, you can instantiate a new device using the Device Profile you created with the Profile Wizard in Citect Project Editor. You only need to configure the Equipment Name and I/O device name and then point to the .CID file for the MiCOM relay. After the process is complete, an XML file will be created for the new device that you instantiated. This will be found in the PSE Project Folder (example: C:\ProgramData\Schneider Electric\PowerSCADA Expert\v7.40\User\YourProjectName). In the example below, we are viewing a device that was instantiated for a MiCOM P443 relay, and the XML file that was created.

This XML file needs to be modified to show the Logical Device Name, and the reports to subscribe to using PSE. The Logical Device Name can be found in the .CID File under Report Control rptID=”IEDNameSystem/…….. In our CID file, we see that the rptID=”P443System/….. is for the Buffered Report A that we configured, and that the Logical Device Name is “System”, which is the Logical Device where the Buffered Report is stored in the relay, and our IEDName is P443 The buffered report PSE will subscribe to is LLN0$BR$brcbA01, which is taken from the CID file rptID=”P443System/ LLN0$BR$brcbA01”. The modified XML file is seen below.
