The attached example provides a simple network where one single phase static generator (converter) is directly being controlled via DSL to set the output active and reactive power (constant power…
The attached example provides a simple network where one three phase static generator (converter) is directly being controlled via DSL to set the output active and reactive power (constant power…
Several EMT studies (transformer energisation, load rejection, ferro-resonance etc.) require a detailed model of the non-linear behaviour of the transformer iron core which is defined by its…
A PowerFactory 2018 (and onwards) example along with two papers is provided for your reference. An example of a PowerFactory implementation of a fast voltage controlled based method for converter…
The static generator allows to control the negative sequence currents via the input signals i2d_ref and i2q_ref. Internally is the cosref, sinref signal used for the transformation (which is typically…
Refer to attached project file. The project contains two IEEE 39 bus test systems connected via two long power lines between bus 29 - bus 09 and bus 23 - bus 10.  The following study cases are…
In order to create a Bode diagram you will need to use the Model Frequency Response command (ComFreqresp). This command is described within the User manual, section "Frequency Response Analysis",…
The individual phases of the AC voltage source (ElmVac) can be controlled in RMS/EMT simulations. For that purpose, the voltage source (ElmVac) is linked Fourier Sources (ElmFsrc) by a composite…
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…
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…
