The Quasi Dynamic Simulation can be remotely connected via OPC to (for example) a SCADA system. In this case the current time stamp of the study case may be needed. There are two solutions available:…
Natural oscillations arise from the inherent dynamic interactions between the power system components, whereas forced oscillations are induced by sustained and periodic external inputs. For instance,…
In the attached example a test grid is used to shown an example configuration for a FFT (Fast Fourier Transformation) element. The example includes two standalone composite models running in parallel,…
This example shows how measured data in Comtrade format can be displayed and replayed. The attached file "Playback_Comtrade_File.zip" is suitable for PowerFactory versions prior to 2025. Please follow…

An UPFC (Unified Power Flow Controller) is a FACTS (Flexible AC Transmission System) device, which consists of two VSCs (Voltage-Sourced Converters). The VSCs are interconnected with each other on…
PowerFactory is able to calculate single-phase interruptions within the short-circuit calculation (complete method) and in the transient simulation. Another option is to connect a three phase line via…

There are several possibilities to calculate the initial conditions. Consider the example y=a*u+b, where y is the output and u the input signal of the model. The initial value of y is known (=0),…
PowerFactory provides the toolbox Quasi-Dynamic Simulation to calculate a set of load flow calculations considering defined time characteristics. For almost every element parameter, characteristics…
