The paper describes a new technique, pseudo-spectra to analyze the stability of power system. The approach allows one to quantify which eigenvalues are sensitive to perturbation and how the sensitivity of the eigenvalues directly influences the transient response. The relation of robust stability and pseudospectra abscissa is discussed and numerical simulation results are shown.
An approach to design power system steady state estimation and transient stability assessment using a multi-machine area network based on multiple synchronized phasors measurements is presented. The oscillations were analyzed from measured synchronized phasors in a multi-machine two area network. The fast Fourier transform (FFT) filter was used to extract the desired frequency from the angular frequency...
A method to analyze stability on a multi-machine power system was developed. For steady state estimation the phasor voltages and angles were used to calculate the frequency deviations. The calculated frequency deviations were then filtered by an FFT filter to extract the power oscillations. By linearly approximating a set of differential equations, the eigenvalues for the system were identified from...
Power system steady state estimation and transient stability is analyzed on a multi-machines network based on multiple synchronized phasors measurements. The oscillations were analyzed from a four machine network and a large power system by using the Fast Fourier Transform (FFT) filter to extract the desired frequency from the angular frequency estimated by measured synchronized phasors. The dynamic...
