Hello all,
I have simulated a single phase electrical distribution network in simulink using the SimPowerSystems library and I need to perform some signal analysis on it. I need to obtain a plot of the electrical signal (either voltage or current) in the frequency domain however this is proving rather difficult as it is a continuous signal.
I have been using the FFT magnitude block with a zero order hold and buffer fed into a vector scope with a frequency input domain. This setup works fine when I simulate the system with a discrete signal input. Once I change the signal to continuous, after making a few adjustments to some of the blocks' settings, I get a blank plot.
Can anyone help me remedy this problem?
Thanks
