WebJan 14, 2024 · In MATLAB/Simulink model, I have used analytic signal block and hilbert's transform method to calculate the real and imaginary components of the faulted phase current. After that I have used the data of real and imaginary components of the faulted phase current to calculate the magnitude, phase, and instantaneous frequency.
