A measurement file object (ElmFile) is used for this purpose. Attached you can find a small example which displays the first 3 channels of a ComTrade file. A measurement file object (ElmFile) is…
The arc voltage of the circuit-breaker can be modelled as a nonlinear resistance. Therefore we connect a resistor (series impedance)in series with the circuit-breaker. Both the real and imaginary part…
Refer to the attached example. It describes an induction generator with the necessary dynamic models. The reactive power is balanced using a switched capacitor. The dynamic models are a shaft model…

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…

For PowerFactory 2021 and earlier please refer to this example and attached files. For PowerFactory 2022 and onwards, this example is not supported anymore. Instead, a much easier alternative is…
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…
