Do you have an example about the FFT (Fast Fourier Transformation) element?

Power Equipment Models

In the attached example a test grid is used to shown an example configuration for a FFT (Fast Fourier Transformation) element. The example includes two Composite Models one using a three phase FFT elements and the other using a single phase FFT element.

In both cases the recommended connection of a clock and Fourier Source element is shown. In the three phase example the Fourier Source signal is assigned to a voltage source element. The predefined plots Plot 3ph and Plot 1ph shown the the FFT output simulation result: magnitude and phase of the respective input signals.

For more information about the ElmClock, ElmFsrc and ElmFft refer to the corresponding technical reference.
