Yes, it is possible to exchange variables between two composite models in the same way as it is done between two common models. It is only necessary to set up a frame in which the two frames are…
The idea of the initialisation is to preset the internal model signals by the results of an initial load flow.The key point is to first check for each DSL-model, which inputs/outputs are known and…
The damping of transient phenomena during a transient simulation is due to 2 causes: Physical damping or numerical damping. - The physical damping is due to the behaviour of the modeled electrical…

You will need to perform an EMT-type simulation for this purpose. To replicate the fault on the cable insulation, the cable must be explictly divided in two sections at the point where the faulty…
If you want to simulate the synchronisation of two different systems, you can model and simulate both systems as separate networks. After some seconds you can then connect them with a circuit breaker…
The attached example project contains the LCC-HVDC benchmark model. The project includes two study cases, one to study the load flow conditions (LoadFlow Conditions) and a second prepared to perform…
Refer to the attached project. The options shown are: Direct start with star-delta switching: Parameter i_star = 1 (Star), i_star = 0 (Delta) Additional rotor resistance: signal rradd (can…
A simple moving average discrete time filter is provided for your reference. It can be used for both RMS and EMT type simulations. The register model (ElmReg) could be used to calculate a moving…
The A-stable integration algorithm is described in the PowerFactory User Manual, Chapter "Stability and EMT Simulations", Section "Algorithm control".…
Refer to the ]attached example for a measured voltage at a bus bar. The inputs of the voltage source are named U_A, U_B, U_C, as you can see in the composite model. These inputs represent the…
