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…
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…

There are many advantages of using built-in PowerFactory models for power electronics, ranging from the simplicity in configuration to the full support of all relevant calculation functions.…

In dynamic simulations, a breaker/switch can be opened via the Switch Event (EvtSwitch). The Switch Event can be parameterised in order to configure the opening process. Furthermore, the breaker…
In dynamic simulations, a breaker/switch can be closed via the Switch Event (EvtSwitch). The Switch Event can be parameterised in order to configure the closing process. Furthermore, the breaker…
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…

Secondary arc currents occur after a fault is cleared (typically by circuit breakers) due to inductive or capacitive coupling with healthy circuits. Such currents are often experienced in long…

Refer to attached project file. The project contains two IEEE 39 bus test systems connected via two long power lines between bus 29 - bus 09 and bus 23 - bus 10. The following study cases are…
For RMS simulations the load type has to be set to 100% dynamic load, this means constant impedance Z. Additionally in the RMS dialogue of the load type the voltage dependency of P and Q can be set.…
