To import the example model, start by creating a new HYPERSIM model and continue by following the steps described in PowerFactory | Importing a Network .

As explained in https://opal-rt.atlassian.net/wiki/spaces/PDOCHSDOCHS/pages/889028859/Examples+PowerFactory+Import+39-Bus+New+England+System#Location , the xml input file for the example can be found under the PowerFactory_ref_model folder.

...

Load flow calculation must also be carried out in HYPERSIM (see the steps in Quick Start | Load Flow). The table below shows the absolute errors in voltage magnitude and angle for all buses in the network model. Please notice that even though in general all error values are negligible, there is a relatively large mismatch in the voltage angle at bus 34 (i.e.,

Mathinline
body\approx
2.5 deg).

The large voltage angle mismatch at bus 34 can be explained by the value of the parallel Transformers parameter in Trf 20 - 34 (see the figure below). As pointed out in https://opal-rt.atlassian.net/wiki/spaces/PDOCHSDOCHS/pages/875528410/PowerFactory+Supported+Features+and+Limitations#Transformers , this feature is not yet supported by the PowerFactory Network Import function.

Note

Source Files in the ScopeView Template Need to be Replaced Before Playing the Recorded Data!

EMT simulation results from the PowerFactory (for this study case) have been included in the PowerFactory_Import_39_Bus_Results.csv file. The data source for the HYPERSIM recordings also needs to be replaced.

Use the Data Source > Replace function in ScopeView to update the data sources.

...

Test sequence:

  1. Run the model for a few seconds.

  2. Stop the model. This will create the …\PowerFactory_Import_39_Bus\PowerFactory_Import_39_Bus_hyp\Recordings folder. The data.oprec file will be retrieved there after simulation.

  3. Open Scopeview

  4. Open the "PowerFactory_Import_39_Bus.svt" template in the main folder

  5. Replace the Power Factory signals with the "PowerFactory_Import_39_Bus_Results.csv" file in the "powerfactory_ref_model" folder

  6. Replace the REC1 signals with the "data.oprec" file in the "powerfactory_import_39_bus_hyp>Recordings" folder

    PF_Import_39_Bus_2.gifImage Added

  7. Play the recorded data with the play button on the left side of the window:
