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…

Refer to the attached example. It describes an synchronous generator with wind turbine model and the necessary controllers. The PWM converter models with DC voltage circuits are modeled in detail…
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…
