There are many advantages of using built-in PowerFactory models for power electronics, ranging from the simplicity in configuration to the full support of all relevant calculation functions.…

This white paper documents the implementation of a detailed EMT model of a three terminal HVDC system using 2-Level Voltage Source Converters (VSC) in PowerFactory, and compares the simulation results…

User-defined controls for Load Flow Calculations as well as Quasi-Dynamic Simulations can be implemented by using QDSL (Quasi-Dynamic Simulation Language) models. In the attached project, two…

The function of a power system stabilizer (PSS) is to extend the small–signal rotor-angle stability limits of the power system by modulating the synchronous machine’s excitation to damp the rotor…
The general line type (TypLne) is based on impedance values and can be defined with or without the neutral wire. Depending on the use case, the neutral can be modelled either explicitly (3 phases +…
It is possible to model a center tapped, single phase transformer in PowerFactory for extended distribution networks with long single phase lines. The attached example shows a possible implementation.…

If you need to place a current transformer (CT) in the neutral of a transformer, the first step is to distribute the neutral connection of the transformer. This can be configured in the…

The loading on an element such as a transformer or line is always based on their current. For a transformer, the loading for each side is calculated from the actual current and the rated current for…

The objective of the attached project is to simulate and analyse the transient recovery voltage (TRV) on high voltage circuit breakers. The circuit breaker itself is modelled by means of a breaker…
A synchronous motor is typically started as an induction machine while a field winding resistance is also used. The "asynchronous" motor starting of a synchronous machine implies the use of rotor…
