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.…
For load -flow analysis enter the synchronous machine as a voltage source, using the steady-state impedances (Xd) and the magnitude of the no-load voltage. This represents the behaviour of the…
In the attached example (FixedSpeedWTG.pfd) an induction generator with the necessary dynamic models is shown. The reactive power is balanced using a switched capacitor. The dynamic models are a shaft…
The attached example (WindCpLambda.pfd) visualises the aerodynamic efficiency cp of the wind turbine, which can be found in the DFIG (doubly fed induction generator) template. Here the cp-lambda…
The consideration of current displacement effects is only important if the complete speed-torque range of an induction machine is of interest, which is usually the case if a motor start-up is…
