ANALYSIS OF FAULT DETECTION ALGORITHM FOR POWER SYSTEM TRANSMISSION LINES USING DFT AND FFT
Subject area: Science,Engineering and Technology · Area of research: Electrical Engineering
Abstract
The Development of Fault Detection Algorithm for power system transmission line consists of two algorithms. Discrete Fourier Transform (DFT) and Fast Fourier Transform (FFT). A block diagram is developed which shows the developmental stages of the algorithms. The DFT and FFT detection algorithms are developed based on their individual applications of Fourier Transform (FT) discretization of phase values of voltage and current to obtain the discrete versions (VP and IP) as the required data for the research. The discretization is followed by DFT and FFT applications to the output result (VP and IP) of the discretization to obtain the time ? domain and frequency ? domain components. Mathematical approach of the implementation of the algorithm is performed and the values of the phase discrete voltage and current values, pre-fault and three phase fault voltage and current magnitudes for DFT and FFT applications were obtained and tabulated
