Configuring a Waveform Extractor project

You can create memory equipment that will allow alarms to be processed and inserted into the alarm log for each Comtrade file acquired by the Waveform Extractor service.

To define a virtual device:

1. If not already defined in your project, create a virtual system equipment as an IEC61850N memory device.

Example of a memory device defined within the example project:



2. Define the I/O device for virtual system equipment by setting the protocol to IEC61850N and Memory to TRUE. See Memory devices for more information.

You can define the variable tags that will be referenced by the timestamped digital alarms.

To set up variable/alarm tags:

1. Create a uniquely named variable tag for each virtual timestamp digital alarm that you will define.
2. Set the Data Type field to DIGITAL.
3. Define the timestamp digital alarms by populating the following fields:
• Equipment: Must display the equipment defined within the Waveform Extractor wizard to acquire Comtrade files.
• Variable Tag A: As defined in step 1.

The remaining fields are customizable.

The following example shows an alarm with the built-in low priority category. It uses custom fields to enable further flexibility around filtering and incident creation in the WebHMI.

You can create an event in the event log for every waveform acquired by the Waveform Extractor with a corresponding timestamp.

To create a waveform event:

1. Create a new Cicode file to initialize waveformsearch.dll to create events for each acquired waveform.

The following Cicode file, which is based on custom configuration, is an example of how to initialize and create alarms with associated Comtrade files:

Copy

FUNCTION Comtrade_Almstartup()

    STRING dirLogging = "[DATA]:..\Logs";
    STRING dirWaveforms = ParameterGet("WaveformDB", "LocalRoot", "[DATA]:WaveformDB");
    
    //Allow the alarm server to start up
    Sleep(30);
    
    IF (0 = WFSearch_Initialize(dirWaveforms, dirLogging)) THEN
        // Did not initialize...
        // Add any messages/warning/logs here
        
        RETURN;
    END
    
    
    WHILE (true) DO
        PLS_WaveformEvent_CreateWaveformEvents("PLSDCluster", "ION_7403", "PLSDCluster.PLS_DEMO\WF1");
        PLS_WaveformEvent_CreateWaveformEvents("PLSDCluster", "ION_7403_2", "PLSDCluster.PLS_DEMO\WF2");
        PLS_WaveformEvent_CreateWaveformEvents("PLSDCluster", "ION_7403_3", "PLSDCluster.PLS_DEMO\WF3");
        PLS_WaveformEvent_CreateWaveformEvents("PLSDCluster", "ION_7403_4", "PLSDCluster.PLS_DEMO\WF4");
        PLS_WaveformEvent_CreateWaveformEvents("PLSDCluster", "ION9000", "PLSDCluster.PLS_DEMO\WF5");
        PLS_WaveformEvent_CreateWaveformEvents("PLSDCluster", "PM8000", "PLSDCluster.PLS_DEMO\WF6");
        PLS_WaveformEvent_CreateWaveformEvents("PLSDCluster", "PM8243", "PLSDCluster.PLS_DEMO\WF7");
        PLS_WaveformEvent_CreateWaveformEvents("PLSDCluster", "PM8243_2", "PLSDCluster.PLS_DEMO\WF8");
        
        
        
        Sleep(120);
    END
END

2. Save the file.
3. In Power Operation Studio, navigate to Project > Setup Wizard.
4. In Startup Functions Setup, add the function you created as the Alarm Server Component's Startup Function.

Your newly-generated timestamped alarms will be visible within the alarm views, as defined by the configured priority and alarm level. It is recommended that custom alarm and incident views are created based on your needs. For more information, see Adding a new Alarms view.
