For lightning transient studies, the line insulators are represented by voltage-dependent switches. There are different options to model the flashover during lightning transients, such as: Voltage…
The duration of an EMT simulation depends on the complexity of the network and integration step size that is configured in the initialisation command (*.ComInc). The integration step size depends on…
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…
Variable resistances can be modelled with the ElmSind. The grounding impedance represents a single phase model. Thus, the ElmSind is modelled as single phase element. The single Rin of the ElmSind is…
An example is provided in the project attached. The state machine is implemented in the block definition "StateMachine" and it is based on DSL statements. It represents a generic example of how the…
The following FAQ provides an example of a DSL configuration script for initialisation: …
The example attached provides an example of a PLL capable of tracking a single phase EMT type signal. As such, the example is supporting only EMT type simulations. The PLL model is based on the Second…
Refer to attached project, in which a DSL block definition "PLL DSOGI EMT 3PH" contains this functionality. Along with other phase-locked loop (PLL) topologies, the DSOGI (double second order…
There are many possibilities to configure and use the System Parameter Identification for time domain (RSM/EMT) simulations. In the attached example, the saturated reactance of the transformer model…

PowerFactory provides the event category Stop Event (EvtStop) to stop a simulation. In order to trigger such an event, a DSL model can used. The DSL model compares the threshold during the simulation…
