An experimental evaluation of a power differential relay is conducted and the results are described. The experimental setup consists of a generator connected to the network via a transmission line protected by the power deferential relay. The relay input signals, fundamental active and reactive powers, are locally computed from the complex product of the current and voltage phasors at each end on...
In this paper, a new fault detection scheme is proposed for transmission systems using Gabor transform (GT) for signal processing purposes instead of the conventional Fourier analysis methods. The detector uniquely detects both low impedance faults and high impedance ones with the same efficacy providing universal and precise fault detection for transmission systems. It utilizes GT as a feature extractor...
In this paper, the generalized 1-D Gabor transformation and possibility of application to power system signal analysis are presented. An artificial neural network based algorithm is employed to compute the Gabor coefficients for further decomposition of the power system signals. The time-frequency resolution analysis for sinusoidal, DC decaying, sudden change and non-integer harmonic signals is carried...
Accurate estimation of current and voltage transient parameter is critical for efficient and accurate fault location computation. In this paper, a new fault location scheme is proposed for transmission systems using Gabor transform for signal processing purposes instead of the conventional Fourier methods. The transform is distinctive with more accurate performance specially when dealing with some...
