Pss Sincal 18.5

The operating equipment of the network must be designed to withstand short-circuits. Until now, this required extensive manual short-circuit calculations for the entire network area, considering the clearing times of the network protection.

The new module Thermal Destruction Analysis enables both the network planning and the protection department to perform an automated check for thermal destruction for all lines, transformers, busbars and breakers in the network.

As a result, the user receives a clear representation of all the checked equipment with simulation results showing thermally destroyed elements. A detailed analysis in the network is directly accessible from the results view. Based on the results, measures regarding network protection or network reinforcement can be derived and their effectiveness can be checked by the Thermal Destruction Analysis.

Thanks to all our PSS®SINCAL users who submit & review ideas through the PSS® Ideas Portal. We are thrilled to highlight four of many ideas which are implemented:

• Click and drag for labels in protection documentation diagrams:
• Deleting network data without graphics:
• Creation of heatmaps based on the bus voltage angle:

Along with the PSS® Ideas Portal ideas, the upcoming release will include several UX/UI improvements based on your direct feedback to the PSS®SINCAL team, including:

• Direct link from graphical elements to settings dialogues or network element data
• Autodetection and opening of network graphic views containing the element to select in network browser, tabular view, etc.
•   Simplified functionality to switch between network graphic evaluation filters in the UI
• Revisited and restructured input data dialogs for controllers (transformer tap changers and shunt elements) according to the user workflow.

It is getting increasingly important to consider the short-circuit current contributions from converter driven plants. The extensions in the short-circuit calculation standard G74 Issue 2 shows exactly this.

With PSS®SINCAL 18.5, this new standard is supported.

Furthermore, the short-circuit current contribution capabilities of converter driven plants are extended to reflect the real converter behavior as realistic as possible. This can be used to extend other short-circuit calculation standards like the IEC 60909 and all calculation methods making use of short-circuit calculations (e.g. protection simulation).
