SimPowerSystems bandpass filter

[davybon]

Hi all,

I have modelled a single wire earth return network in simulink using the SimPowerSystems library and I now want to filter the current and voltage signals to find the magnitude of various harmonic frequencies. Does anyone have an idea of how I can approach this?

I have found a bandpass filter in the Signal Processing Blockset library however the help file is vague an unclear when using this block for such a system.

Has anyone had any experience in this area who can give me a hand?

Thanks

Davybon

You can use the THD (total armonic distortion) component from the powerlib >extra library >measurements
