Simulation control model of synchronous motor based on PSO algorithm optimization in power system
Energy Reports, 2022 Under normal operation, the power angle, voltage and frequency of a power system should be stable. The periodic instability of power angle occurs after small disturbance, which is the low-frequency power oscillation of power system.

Acoustic Saturation in Bubbly Cavitating Flow Adjacent to an Oscillating Wall [PDF]
, 2000 Bubbly cavitating flow generated by the normal oscillation of a wall bounding a semi-infinite domain of fluid is computed using a continuum two-phase flow model. Bubble dynamics are computed, on the microscale, using the Rayleigh-Plesset equation.

Discovery of spatial periodicities in a coronal loop using automated edge-tracking algorithms [PDF]
, 2008 A new method for automated coronal loop tracking, in both spatial and temporal domains, is presented. Applying this technique to TRACE data, obtained using the 171 Å filter on 1998 July 14, we detect a coronal loop undergoing a 270 s kink-mode ...

Transient Oscillation Suppression Method of Modular Multilevel DC Transformer
IEEE Access, 2020 The modular multilevel DC transformer (MMDCT) is more likely to suffer from transient oscillation, which is caused by insufficient damping of the equivalent RLC circuit with smaller arm resistance and submodule capacitance and may threaten the system ...

Decentralized H ∞ control for damping power system oscillations
Open Engineering, 2011 Abstract Inter-area oscillations are serious problems to large-scale power systems. A decentralized H ∞ generator excitation controller of a power system is proposed to damp the inter-area oscillations and to enhance power system stability.
