The attached project shows the energisation of the electrical grid and the active power load pick up with the voltage source converter (VSC) in EMT simulation. The DC capacitor is charged through a…
The ferroresonance phenomena is a non-linear series resonance that may result in transient currents of high amplitude and high harmonic content. For medium voltage networks the following system…
The full network model might not be available for the harmonic analysis or the full model has to be reduced for performance reasons. Examples are: Harmonic Analysis for a power plant (e.g. wind farm /…
There are various possibilities to "bond" the sheath / metallic screen (MSC). The bonding corresponds to the earthing of the sheath / MSC. There are different bonding configurations for cables: …
Working a lot with PowerFactory can lead sometimes to quite large result objects which occupy space on the hard disc. The attached Python script can list for you the total size of each project to help…
The Unit Commitment and Dispatch Optimisation module was introduced in PowerFactory version 2019 with an interface for external (commercial) linear programming solver. The solvers GUROBI and IBM CPLEX…
The attached document shows the steps necessary to plot an impedance trajectory in the RX diagram. The steps are the same for RMS and EMT simulations and also explained below: 1. Locate the polarizing…
Using element parameter via signals is not possible in DSL but the configuration script, available since V2020, can help you to get the task done. The configuration script is defined in the type…
There are two possible ways: 1) Right click on the asynchronous machine of interest using the right mouse button and choose->Show->Time-overcurrent plot. A new time overcurrent plot will…
When a short circuit calculation is successfully executed, the user can select the following impedance values in the result box of each branch element: * Source Impedance Rs,Xs,Zs and phizs (available…
