Windows for DFT - Based Harmonic Analysis
نویسنده
چکیده
Relation between roots location and spectrum: The first important thing in the use of windows for harmonic analysis, is the relation between the zeros of the windows, and their spectra. The plot in Figure 3.1 shows the spectrum of the rectangular window and the roots of this window. This plot outlines that the width of the main-lobe is obtained from the angle of the first root, in this case, Θ=2π/32.

Fault Locating in High Voltage Transmission Lines Based on Harmonic Components of One-end Voltage Using Random Forests
In this paper, an approach is proposed for accurate locating of single phase faults in transmission lines using voltage signals measured at one-end. In this method, harmonic components of the voltage signals are extracted through Discrete Fourier Transform (DFT) and are normalized by a transformation. The proposed fault locator, which is designed based on Random Forests (RF) algorithm, is train...
