EMTP and HYPERSIM share the same user interface and network data format (*.ecf); thus, EMTP models can be open in HYPERSIM. However, the functionalities of the two software are not the same. Therefore, additional steps are required to simulate an EMTP model in HYPERSIM.

A point of wave (POW) must be included in all the HYPERSIM models, see Point-on-Wave Synchronization for details. It is remarked that the voltage source model from EMTP is based on a cosine function, while the HYPERSIM voltage source is based on a sine function. Thus, to maintain the same phase from the EMTP simulation, the POW is connected to an auxiliary HYPERSIM voltage source with the angle set as zero. The following Figure shows the final HYPERSIM model.

The following Figure shows the simple example model after replacing the switch in HYPERSIM. The definition of T1 in CB1 is set accordingly to reproduce the switching events from EMTP, i.e., the breaker is initially closed and then open at 4 ms, see the following Figure. The user can find more details about the settings of the HYPERSIM breakers in Circuit Breaker, 1-Phase Circuit Breaker.
NOTE: For this example model, it was not needed to set voltage levels for buses and run the load flow and since there are no synchronous machines or exciters or else. There was no need to verify the compatibility of EMTP controllers either. Therefore, after step 2, it is time to run the simulation.

The following Figure shows the simulation results obtained in both HYPERSIM and EMTP. It is observed that results from both software are superimposed.
IEEE 39 Bus Benchmark
EMTP model
This example considers the network IEEE39_345kV_2018_02_05.ecf available in the example models of EMTP 4.1, see the following Figure. The model is a 345-kV system of 39 buses that includes synchronous machines, 3-phase loads, two-winding and three-winding transformers. Note that the names of buses 6 and 16, and the load 16 are remarked in red in the Figure.
...
The series-connected EMTP switch must be replaced manually by the circuit-breakers in HYPERSIM if they are not externally controlled. The following Figure shows the model of the subcircuit load 16 after replacing the switch in HYPERSIM. Note that the switching times in the CB2 breaker correspond to the ones from the EMTP model. The user can find more details about the settings of the HYPERSIM breakers in Circuit Breaker, 1-Phase or Circuit Breaker or , 3-Phase Circuit Breaker.

The example model in HYPERSIM is configured to work with CP models. However, the user can change the CP line models to FD models if needed. The EMTP FD line components need to be replaced by the native HYPERSIM FD line components manually. Note the line data (*.pun files) need to be generated and loaded for every line when using the FD line models, as the same way that is required in EMTP, see Frequency Dependent, 3-ph for details.
