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…

All parameters are referred to the stator, also the rotor impedances. In many data sheets, you find R2’ and X2’ being the rotor resistance and reactance in Ohm referred to the stator. In this case,…
