Title
Impedance analysis of a power line distribution network using short-time Fourier Transform
Abstract
The impedance of a low voltage distribution network is analyzed and presented. Data collected from field measurement which was done over one week is used in this analysis. Basically, a chirp is injected into the electric grid, and the voltage and current signals (corrupted by various noises, including the 50 Hz mains signal) are time-sampled and stored for processing. The voltage and current are processed to obtain the impedance of the electric grid. Simulations are performed to establish the efficacy of the method of analysis used to obtain the impedance. The sliding window method of the Discrete Fourier Transform (DFT) is used in analyzing these impedance values. An eventual channel model describing the network is also presented.
