This example provides an introduction to the analysis of arc furnaces and their influence to the supplying power system. The analysis covers the identification of the injected harmonic currents, the…
The example shows the user defined MMC model of the statcom. The model can only be used in the EMT simulation and in PowerFactory 2021 on-wards.…
This example can help you understand the following: - the purpose of the commutation reactance while applying it to the HVDC-LCC element (ElmHvdclcc); nevertheless, the same procedure applies to line…

According to VDE/IEC in standard system fed directly from generators without transformer units, the corrected generator impedance defined in following equation has to be used. Z_GK = K_G x Z_G = K_G x…
The Q(V) characteristic is available as reactive power controller for load flow calculation within the generator models as well as within the station controller. The slope of the control curve can be…
To simulate the charging behaviour of electric vehicles in PowerFactory the template “DIgSILENT Electric Vehicle” from the global library can be used. This is done by using a QDSL (Quasi-Dynamic…
