Web3 jun. 2024 · I am working on the fault detection and fault classification in electrical power system using wavelet and ANN in MATLAB/Simulink. I have already collected the data for the fault currents in the three phases and ground (A, B, C are the phase currents and G is the ground current) as well as the fault coefficients m, n, p, q for the respective three … WebMatlab was used to import and filter the image. The first step is to choose a wavelet type, and a level N of decomposition. In this case biorthogonal 3.5 wavelets were chosen with a level N of 10. Biorthogonal wavelets are commonly used in image processing to detect and filter white Gaussian noise, ...
