Hi,

I am wanting plot the magnitude vs frequency for a capacitor. This seems like it should be pretty easy and straight forward in Matlab, but I'm not sure how to do that. Any help would be appreciated.

Thanks, Josh

i have a similar question, working on HVDC terminal station, "plot the magnitude of the filter impedance as a function of frequency up to the 23rd harmonic frequency" I'm using single tuned harmonic filter. given in the question the inductor values for L(5,7,11,13), the capacitor values for them and the resistors. Q= 50 for all,

(high pass) Chp=0.834*10^-6, Rhp=226 , Lhp=0.042 , Q=1.

Sk= 23127Mva

Uk=0.15

voltage on transformer = 275/116KV

Hi,

You can use the SimPowerSystems in MATLAB to model and simulate any electrical system.To build and simulate an electrical circuit please refer to the link below:

And, the link below explains how to analyze a simple electric circuit and generate plots of frequency versus impedance or frequency versus phase:
