Relaxation oscillation suppression in continuous-wave intracavity optical parametric oscillators
Optics Express, 2010 We report a solution to the long standing problem of the occurrence of spontaneous and long-lived bursts of relaxation oscillations which occur when a continuous-wave optical parametric oscillator is operated within the cavity of the parent pump-laser. By placing a second nonlinear crystal within the pump-wave cavity for the purpose of second-harmonic ...

A Strategy for Forced Oscillation Suppression
2024 IEEE Power & Energy Society General Meeting (PESGM), 2020 Wide-area time-synchronized measurements have recently revealed troublesome forced oscillations (FOs) within modern synchronized power grids. In some cases, these FOs represent a dangerous hazard to the system. Recent research has focused on locating the source of FOs to provide operators with knowledge for mitigating their impact locally.

A Sub-Synchronous Oscillation Suppression Strategy for Doubly Fed Wind Power Generation System
IEEE Access, 2021 During the power transmission of doubly-fed induction generator (DFIG), due to the influence of series compensating capacitance and long-distance transmission, DFIG is prone to sub-synchronous oscillation, which damages the stability of the system.

Enhanced Power Decoupling Strategy for Virtual Synchronous Generator
IEEE Access, 2020 Power coupling caused by high impedance ratio and nonzero power angle is a crucial issue for virtual synchronous generator (VSG), which may result in output power error, slower power response and even invalid operation.

Neutrino wave function and oscillation suppression [PDF]
The European Physical Journal C, 2005 We consider a thought experiment, in which a neutrino is produced by an electron on a nucleus in a crystal. The wave function of the oscillating neutrino is calculated assuming that the electron is described by a wave packet. If the electron is relativistic and the spatial size of its wave packet is much larger than the size of the crystal cell, then ...
