The IEEE 39-bus system is well known as 10-machine New-England Power System original presented in [1], which consists of 10 generators, 39 busbars, 12 transformers and 19 loads. The original benchmark network is an example model in PSCAD v5 [2], extra components are added to test fault transients in the PSCAD reference model provided with this example. Then, the PSCAD reference model is imported to HYPERSIM via [The Unified Database]. In both the PSCAD reference model and imported HYPERSIM example model, each machine (generator) is represented as a voltage source, and its source impedance is arbitrarily set at 10 Ohms. This example demonstrates that the PSCAD model has been imported successfully and all the components have been mapped with the correct parameters in HYPERSIM. All the necessary components required to complete the IEEE-39 bus benchmark model in HYPERSIM are available at The Unified Database. For this example, two fault scenarios are considered on Bus 1. Users can modify fault times as required or add new faults to other buses as well.

It is noted that PSCAD reference model disconnect disconnects the Bus 1 from the system with two breakers at 0.4s, the PSCAD breakers and switching operation are imported to the HYPERSIM model as well. The breaker operation time is configured with breaker logic component as
...
The following figures compares compare the HYPERSIM (REC1) and PSCAD (PSC1) simulation results following the three-phase fault on Bus 1.
...
It is noted that instantaneous waveforms measured from the imported HYPERSIM model perfectly overlaps with the results from PSCAD reference model. This validate validates the accuracy of imported HYPERSIM model.
...
It is assumed that the timed fault logic component and breakers used to disconnect Bus 1 operates operated in the the same manner as scenario 1; thus, no further modifications are required.
The following figures compares compare the HYPERSIM (REC1) and PSCAD (PSC1) simulation results following the Single-phase fault on Bus 1.
...
The accuracy of the imported model is also verified with a an unbalanced fault, the imported HYPERSIM model provide provides decent accuracy when compared to the PSCAD reference model.
