Is there a block in Simulink or Simscaope to model a frequency controlled voltage source, with e.g. 100 V on each frequency from nominal frequency up to 100 kHz?

Hello Sven,

you can either create it yourself as shown below, or use the programable voltage soucre in simscape electrical. It has the option to input the desired frequency if you open up its settings: https://www.mathworks.com/help/physmod/sps/ref/programmablevoltagesource.html

Dear Joel,

just tried your solution however, I need to combine the voltage source with a frequency dependent distributed power line block and it is probably not the same domain. Is there a chance to use an electrical voltage source to model the source and the line and analyse it with a powerful-block?

you can use the simulink model with a specialized power systems controlled voltage source as well. Both simscape and specialized power systems have frequency dependent transmissin lines.

For more options with specialized power systems, see: https://www.mathworks.com/help/physmod/sps/powersys/ref/threephaseprogrammablevoltagesource.html

for transmission lines in simscape, see:https://www.mathworks.com/help/physmod/sps/ug/frequency-dependent-transmission-line.html

Joel
