An ideal symmetrical system has the following phase shifts for harmonics of the nth order:A: 0°B: -n*120°C: n*120°For the third harmonic, for example, the phase shifts amount to:A: 0°B: -360°C:…
To assign a spectrum to the load element, firstly add a load type to the load element and then set the model to current source. The spectrum must be defined and assigned under the Harmonics page of…
For being able to consider frequency dependent network impedances you may use the Voltage Source element (ElmVac) or the External Grid element (ElmXnet). On the Harmonics-page, frequency…
In the attached project (RippleControl.pfd) two different methods of modelling ripple control systems are illustrated: The study case "Serial Infeed" shows the simplified way by just inserting a…
There are two ways to simulate the harmonic voltage distortion from the feeding grid: To model the infeed as a voltage source and entering the harmonics on the Harmonics page. To model the infeed as…
The PWM converter model can either represent a harmonic current source or a harmonic voltage source. If you select the option "Constant I", the specified harmonic spectrum is injected as harmonic…
You may use the Time Characteristic with data acquisition from a file. To use it you have to define a Time Characteristic of type ChaTime and choose the path and the format of the external file. This…
Attached is an example (ExampleTCSC.pfd) of a Thyristor Controlled Series Capacitor (TCSC) including a control for power oscillation damping (POD) to be used with RMS simulations.…
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…
The attached files illustrate two model implementations (SVCExampleWithoutSVSInterface.pfd and SVCExampleWithInterface.pfd): individual control or synchronized control of parallel SVS devices: 1.…
