This example provides an introduction to the analysis of arc furnaces and their influence to the supplying power system. The analysis covers the identification of the injected harmonic currents, the…
DSL (DIgSILENT Simulation Language) is a very powerful possibility for modelling time continuous controls and processes. But modelling discrete controls rises some problems. There is on one hand the…
A simple moving average discrete time filter is provided for your reference. It can be used for both RMS and EMT type simulations. The register model (ElmReg) could be used to calculate a moving…
The Matlab Simulink - PowerFactory simulation interface is described in detail in the User Manual, Chapter "Models For Dynamic Simulations", Section "Matlab Interface". A simple Simulink Model…
You will need to perform an EMT-type simulation for this purpose. To replicate the fault on the cable insulation, the cable must be explictly divided in two sections at the point where the faulty…
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 lightning event can be modelled in PowerFactory in two ways: using the built-in impulse source element (ElmImpulse) - recommended approach. using a detailed, user defined DSL model. The first method…
In the attached PowerFactory project, a current source is configured to inject fundamental frequency and harmonic currents into the system. The simple network model contains a current source which is…
Refer to the attached example. It describes an induction generator with the necessary dynamic models. The reactive power is balanced using a switched capacitor. The dynamic models are a shaft model…
The options available are the following: Voltage  Measurement Device and Current Measurement Device (StaVmea and StaImea). These elements implement the measurement of time-dependent data of a…
