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…
The surge arrester model consists of a non-linear resistance that can be entered point by point.  The surge arrester is connected to Bus B and the element input characteristic is governed by…
In the rectifier model, you can specify a rectifier as either a rectifier with a commutating reactance or just as a rectifier without a commutating reactance. The Technical Reference…
The attached example includes the VSD_200kW template representing a variable speed drive driving a 200 kW motor.  The example provides two study cases: Simulation in EMT of the starting sequence…
It is recommended to have only more than one slack generators in the following cases: Lump representation of the external network: when you have two connections from your network and…
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.…
A neutral earthing compensator (NEC) or neutral earthing resistor (NER) is modelled in PowerFactory as an element that needs no type. The rated voltage, rated current, zero sequence and zero…
The polarity field is used to correct or adjust the proximity of the ends of coupled lines in the case that they have been incorrectly defined. When the user draws lines in PowerFactory, the i and j…

In the attached model, you will find how to model the capacitive and inductive couplings of overhead lines. The example includes study cases that demonstrate: Single line model to study the behaviour…
