There are two places where this can be configured: one is the global configuration and the other is in the user settings.The user setting (Tools - User Settings...) is under Miscellaneous: Manually -…
A blocking relay is setup in the example provided. The relay located at the top busbar has its first Ioc element blocked for faults downstream of the middle busbar. The second Ioc element will trip…
The attached project contains a small medium voltage network with four loads of different behaviour. The loads are supplied by a synchronous generator driven by a diesel engine. Additionally there is…
A model of a Modular Multilevel Converter (MMC) is included in PowerFactory since Version 2016. The document "PowerFactory 2016 - What's New" gives an overview of the MMC model.…
DIgSILENT developed an EMT model of a VCB based on [1] (hereafter referred to as Greenwood’s model). Greenwood’s model simulates the voltage recovering characteristic of a VCB after contact separation…
A simple test system is provided in order to analyse using Quasi-Dynamic Simulation the behaviour of a microgrid containing PV systems and a battery system. The network can be configured in order…
An OPC Tutorial is available in the DIgSILENT download area (http://www.digsilent.de/index.php/downloads.html) under Advanced Tutorials. The tutorial contains an OPC guide with information on how to…
The purge process removes old entries from the history.Each PowerFactory project has a history where all changes are recorded. The default is to save this history for 7 days.The purging removes older…
- Source Impedance parameters Rs, Xs and Zs represent the equivalent impedance seen from the considered location back to the source of short circuit current. - Fault Impedance parameters Rf,Xf and Zf…
The attached example project shows three different possibilities to implement automatic voltage regulators (AVR), installed along a line. The most left arrangement uses an auto transformer, where the…
