A lightning event can be modelled in PowerFactory in two ways: using the built-in impulse source element (ElmImpulse) - recommended approach. using a detailed, user defined DSL model. The first method…
The attached example demonstrates the use of stochastic switching in PowerFactory, including a description on how to use it. The study case contains a DPL script "Stochastic Switching" which…
To model the initial conditions (voltage) of a capacitor bank, you should use a "parameter event" (SetParam) on the variables "uC_a", "uC_b", "uC_c" (signals of the "ElmShnt"). Please find attached an…
To define harmonic background voltages you have to link a voltage source with a DSL model or a fourier source. Refer to the example in the attached file.…
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…
In the attached PowerFactory project, a current source is configured to inject fundamental frequency and harmonic currents into the system. The simple network model contains a current source which is…
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…
