In general, instantaneous values are calculated in EMT simulations. Such instantaneous values must be processed in order to calculate RMS signals, such as voltages and current. The following are two…
DSL (DIgSILENT Simulation Language) is a very powerful possibility for modelling time continuous controls and processes. But modelling discrete controls rises some problems. There is on one hand the…
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…
Please refer to the attached example.…
Please refer to attached project. The project exemplifies the following systems: - Single phase diode rectifier, full bridge with capacitive load - Single phase diode rectifier, full bridge…
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.…
In this example an IEC compliant DLL based dynamic model named "DFT analyser" is provided intended for EMT simulations. It retrieves the magnitude (i.e. peak value of sine wave) coefficient of a…

It is possible to use the results of the Prony Analysis in a DSL model in order to generate a synthetic time domain curve as a summation of all resulting individual components. The generated curve can…
PowerFactory offers with the simulation scan also the possibility to observe the solver. This allows the user to define a parameter simulation scan which can stop the simulation in case of high number…
In order to modify the inductance and resistance of the Series Reactor element within an EMT simulation, then the following signals must be set externally from a user defined model (e.g. DSL or…
