Attached is an example (ExampleTCSC.pfd) of a Thyristor Controlled Series Capacitor (TCSC) including a control for power oscillation damping (POD) to be used with RMS simulations.…
The options available are the following: Voltage Measurement Device and Current Measurement Device (StaVmea and StaImea). These elements implement the measurement of time-dependent data of a…
In the attached example (FixedSpeedWTG.pfd) an induction generator with the necessary dynamic models is shown. The reactive power is balanced using a switched capacitor. The dynamic models are a shaft…
The attached example (WindCpLambda.pfd) visualises the aerodynamic efficiency cp of the wind turbine, which can be found in the DFIG (doubly fed induction generator) template. Here the cp-lambda…

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,…
For load flow calculation, static analysis, the three phase voltages can only be altered by specifying the amplitude and the phase lag in the positive, negative and zero sequence system of the voltage…

For RMS simulations the load type has to be set to 100% dynamic load, this means constant impedance Z. Additionally in the RMS dialogue of the load type the voltage dependency of P and Q can be set.…
It is possible to represent photovoltaic (PV) systems in PowerFactory for the purpose of power system analysis. It is important to decide from the very beginning on the type of analyses being carried…
