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…
This can be defined in the load-flow page of the transformer. The attached example shows how to use a phase-shift transformer to control the active power shared between several transformers feeding a…

The example attached includes a measurement file drive in a 3-phase load. Import the project, save the data file loadmeas.txt to the hard disk and select this file in the measurement file object of…
PowerFactory is using the rated power of the turbine as an additional input parameter to the turbine model and converts the turbine output (in turbine-p.u.) to synchronous machine p.u. at the output…
In the attached example, the output power of a single-phase load is controlled via an external file element (ElmFile). Import the project, save the text file to the hard disk, and select this file in…
In the attached example a ramp modeled in DSL is used to reduce the turbine power pt from its initial value to zero. You also may use a similar block structure to impose a ramp on any other machine…

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.…
The attached example shows a single generator infinite bus bar system that goes through three swings before it gets unstable. Power Swing Blocking: The relay is measuring the time of the impedance…
