The attached document shows the steps necessary to plot an impedance trajectory in the RX diagram. The steps are the same for RMS and EMT simulations and also explained below: 1. Locate the polarizing…
The ferroresonance phenomena is a non-linear series resonance that may result in transient currents of high amplitude and high harmonic content. For medium voltage networks the following system…
A power electronic converter, used in photovoltaic, wind power or HVDC application for example, has a frequency-dependent equivalent impedance, which depends on controller design and physical…
A relevant example is provided in the attached project. Please refer to the attached pdf document for a description of the model aggregation principles.…
Attached you find an example with 3 unsymmetrical voltage sources. It is required to use 3 symmetrical voltage sources and to connect them to the load busbar using 3 single-conductor cables (phase A…

A static load model is always equivalent to a constant impedance model. For modelling any other characteristic, you have to define a general load type (TypLod) and, on the Simulation RMS page, switch…
In the attached example project the battery is connected to the grid using a PWM converter. The grid contains a synchronous machine which supplies a load. After the initialization the synchronous…
There are several ways of modelling an SVC system: Using the SVS Interface in PowerFactory: A number of standard controls for SVS are available in the global library. There, you can also find…

Refer to the attached project. An example of a photovoltaic (PV) system running in parallel with a synchronous generator is provided. The PV generator (Static Generator) is feeding the load. The grid…
For synchronising a synchronous generator to a power network you need to consider the following: The flag spinning in isolated operation (load flow page) should be enabled. Otherwise the synchronous…
