AbstractClosed‐form expressions are obtained to calculate the approximate complex eigenvalues and eigenvectors of a system composed of a non‐classically damped primary structure and a single degree of freedom oscillator. The expressions are obtained through a systematic second order perturbation analysis of a transformed eigenvalue problem of the ...

Journal of Sound and Vibration, 1979
Explicit criteria for the optimum design of an untuned viscous dynamic vibration absorber are developed for the case of a viscously damped single degree of freedom springmass system. It is shown that for the particular case of an undamped main system, the results reduce to the classical ones obtained by using the concept of a fixed point on the ...

Journal of Sound and Vibration, 1981
The frequency locus method is summarized and then applied to the optimization of the spring and damper rates for a dynamic vibration absorber. The primary system to which the vibration absorber is attached consists of a force-excited sprung mass with associated viscous damping.

3rd Renewable Power Generation Conference (RPG 2014), 2014
In this paper wind farm cooperated load frequency control to damp load frequency fluctuations in multi-area power system is proposed and investigated. Multi-area power system consists of three types of conventional power plants (hydro, thermal and nuclear) and two variable speed wind turbine (PMSG and DFIG) based wind farms.

The paper discusses the impacts of the advanced closed loop control through multi-functional multi-band power system stabilizers on dynamic performance of the New York State power grid. Reference signal modulation of certain devices in the system has been shown to improve system damping and affect frequency response during generator outage scenarios ...
