Identification of low frequency oscillation modes in large transmission systems

open access: yesRevista Facultad de Ingeniería Universidad de Antioquia, 2017
There is a typical dynamical performance associated with every system. Oscillations are phenomena inherent to dynamical systems and the analysis of such phenomena is a fundamental issue for understanding the dynamical behavior of a particular system ...

Online Evaluation Method for Low Frequency Oscillation Stability in a Power System Based on Improved XGboost

open access: yesEnergies, 2018
Low frequency oscillation in an interconnected power system is becoming an increasingly serious problem. It is of great practical significance to make online evaluation of actual power grid’s stability. To evaluate the stability of the power system

Nonergodic Brownian oscillator: low-frequency response

open access: yesJournal of Statistical Mechanics: Theory and Experiment, 2023
Abstract An undisturbed Brownian oscillator may not reach thermal equilibrium with the thermal bath due to the formation of a localized normal mode. The latter may emerge when the spectrum of the thermal bath has a finite upper bound ω 0 and the oscillator natural frequency exceeds a critical value

Low frequency longitudinal relaxation oscillation [PDF]

open access: yesPACS2001. Proceedings of the 2001 Particle Accelerator Conference (Cat. No.01CH37268), 2002
From the recent data analysis of the longitudinal feedback system and the streak camera, we have found a longitudinal relaxation beam oscillation whose frequency is a multiple of 36 Hz. When the relaxation oscillation is generated, horizontally oscillating wide beams are observed at the diagnostic beamline, and the beam lifetime is fluctuated.

Online Monitoring of Low-Frequency Oscillation Based on the Improved Analytical Modal Decomposition Method

open access: yesIEEE Access, 2020
With increasing complexity of the power system, and the gradually expanding scales, the probability of low-frequency oscillation (LFO) is increasing, and its performance is more diverse.

LOW-FREQUENCY SWASH OSCILLATION

open access: yesDoboku Gakkai Ronbunshu, 1993
Swash oscillation の周期は入射波のそれに比べて長くなることが知られている. こうした swash oscillation の長周期化を水理実験および有限振幅長波理論に基づく数値モデルにより検討し, 長周期波のほかに, swash zone での寄せ波と引き波の時系列に依存する追い付き・合体・吸収といった相互干渉によっても長周期の swash oscillation が形成されることを示した.
