The Thevenin and Norton equivalents are characterized by their open-circuit voltage and short circuit current. The inner voltage source of the Thevenin equivalent equals the open circuit voltage,…
Harmonic load flow calculation and frequency sweep calculations require detailed models of lines that are also representative for higher frequencies. For that purpose, overhead lines and cable systems…
Harmonic load flow calculation and frequency sweep calculations required detailed models of lines that are also representative for higher frequencies. For harmonic analysis, overhead lines and cable…
Cable systems can be modeled in PowerFactory using either sequence data or geometrical data of the single core cable and cable system arrangement. The PowerFactory project which is attached with this…
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…
Please refer to attached project. The project exemplifies the following systems:   - Single phase diode rectifier, full bridge with capacitive load - Single phase diode rectifier, full bridge…
In this example an IEC compliant DLL based dynamic model named "DFT analyser" is provided intended for EMT simulations. It retrieves the magnitude (i.e. peak value of sine wave) coefficient of a…
To calculate the mutual impedance, a current is injected to bus 1 and the voltage at bus 2 is calculated, while all other sources in the system are deactivated (voltage sources short-circuited and…
