The surge arrester model consists of a non-linear resistance that can be entered point by point.  The surge arrester is connected to Bus B and the element input characteristic is governed by…
The attached example project contains the LCC-HVDC benchmark model. The project includes two study cases, one to study the load flow conditions (LoadFlow Conditions) and a second prepared to perform…
Refer to the attached project. The options shown are: Direct start with star-delta switching: Parameter i_star = 1 (Star), i_star = 0 (Delta) Additional rotor resistance: signal rradd (can…
A simple moving average discrete time filter is provided for your reference. It can be used for both RMS and EMT type simulations. The register model (ElmReg) could be used to calculate a moving…
The A-stable integration algorithm is described in the PowerFactory User Manual, Chapter "Stability and EMT Simulations", Section "Algorithm control".…
Refer to the ]attached example for a measured voltage at a bus bar. The inputs of the voltage source are named U_A, U_B, U_C, as you can see in the composite model. These inputs represent the…
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.…
