Independent Component Analysis (ICA)

15 Statistical Features (SF) calculated on the Extended Park quantity (ip), then performing ICA gives the 2D and 3D plots shown below:

Fast Fourier Transform Analysis on: Parks and Extended Parks Quantity

Image
  Extended Park Vector Approach and 15 Statistical Features The EPVA method works by converting the three-phase currents (i_sa, i_sb, i_sc)  into direct and quadrature axis (id and iq)    and it finds the modulus id + jiq (ip) of     as follows [1]: Note: Sample length = 100 samples           Overlap = 65 samples   Fast Fourier Transform (FFT) analysis: Characteristic Fault Frequencies (CFFs) 0.3% fault at no load and 100% load (a) 0.7% fault at no load and 100% load (b) Figure 1: Frequency response at no load and 100% load condition, (a)  for 0.3% severity and (b) 0.7% severity   1.05% fault at no load and 100% load (a) 2.1% fault at no load and 100% load (b) Zoom view of the Parks quantity (c) Figure 2: Frequency response at no load and 100% load condition, (a)  for 1.05% severity, (b) 2.1% severity and (c) zoom view of id, and iq .
