The active and reactive power settings are the combined power of stator and rotor. When setting the machine to Generator on the Basic Options page, the machine is in generator-orientation and a…

In the attached example (PhotovBattery.pfd ) two explicit modelling approaches are shown. The models we recommend for PowerFactory simulations are very similar to each other. The PV generator consists…

The unit is machine p.u. (rated power and rated voltage of the corresponding machine). This parameter is only used in IEC short circuit calculations.…
Tags
This value is an alternative input for the synchronous reactance. It is the permanent short circuit current in case of rated IEC conditions (1.1*Un subtransient voltage) and a direct short circuit at…

With these parameters you can specify a frequency characteristic for r and l” (subtransient inductance) for consideringskin effect and the variation of the internal inductance. Relevant for harmonics…
Tags
This flag indicates if the machine reactance should be calculated using all transient parameters (xdss, xds, xd, Tdss, Tds), or if just the subtransient reactance should be used for harmonics. There…

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…
Tags
The best option is to model the TCR using a SVC model and setting the number of capacitors to zero, as shown in attached example. In order to analyze the harmonic distortion of the current…

This can be modelled using an external tap controller or a master-slave mode. First of all, both transformers shall have a type which includes settings for the tap changer. In addition, the…
