This example provides an introduction to the analysis of arc furnaces and their influence to the supplying power system. The analysis covers the identification of the injected harmonic currents, the…
The attached example shows how an AC current source (ElmIac) is controlled during a RMS simulation. In the first study case the amplitude and the angle of all phases are equally controlled, requiring…
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…
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…
Assuming a harmonic voltage measurement is present and needs to be converted into current injections, the following steps need to be taken:1. Convert the measurement data from phase voltage…
