In some special cases values of element parameters, e.g. the base apparent power, can be transferred from the element, e.g. synchronous machine, to the control models so it is not necessary to insert…

Several things are generally worth to keep in mind when executing an EMT simulation with PowerFactory: 1. Necessity of accurate representations of line models. PowerFactory offers lumped as well as…

A Matlab Simulink model can be easily linked with a PowerFactory dynamic simulation by means of the FMI Standard. Matlab SImulink models can include various components, including Matlab Scripts or…
You try to connect a power or current measurement device (StaPqmea or StaImea) but you get the message: "Selected Object NodeName 'Terminal' is not a 'Cubicle'". You have to select in this case on the…

DIgSILENT developed an EMT model of a VCB based on [1] (hereafter referred to as Greenwood’s model). Greenwood’s model simulates the voltage recovering characteristic of a VCB after contact separation…
The integration method is determined by the setting “Damping factor” in the "Calculation of Initial Conditions" command dialog, page "Solver Options", as follows: - “Damping factor” = 1: trapezoidal…
The general rule is that PowerFactory provides access within DSL to variables belonging to a certain network element only if they are marked correspondingly in the Variable Selection dialog, under the…

PowerFactory includes built-in devices to measure current (StaImea), voltage (StaVmea) and power (StaPqmea). Since PowerFactory version 2022, these devices calculate the instantaneous values, true RMS…
The following models are available in PowerFactory (see attachment): Lumped PI model Distributed Constant Parameter, also known as Bergeron model Distributed Frequency Dependent Parameter Modal Domain…
The AC voltage source can be controlled in RMS simulation by applying different input values to signal sets (u0,f0) or (Ul0,F0Hz). The first set controls the per unit quantities, the second absolute…
