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…

An example is provided attached depicting a linear and a non-linear dynamic load model.…
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…
