The second system of the IEEE second benchmark model of Subsynchronous Resonance (SSR) is considered. The system can be mathematically modeled as a set of first order nonlinear ordinary differential equations with the compensation factor (μ = Xc/XL) as a bifurcation (control) parameter. So, bifurcation theory can be applied to nonlinear dynamical systems, which can be written as dx/dt = F (x;μ)...

This paper will focus on identifying the interacting dynamic phenomena in power systems by using continuation of invariant subspaces (CIS). With this approach one can trace the trajectory of different oscillatory modes as system parameter changes. Many power system dynamic phenomena, such as strong resonance, subsynchronous resonance (SSR) et al., are related to the interaction of oscillatory m...

Dynamically switched resistor banks connected to the generator transformer bus are known to improve transient stability of the power system. In this article, a braking resistor control strategy designed through fuzzy logic control theory has been proposed to damp the slowly growing subsynchronous resonant (SSR) frequency oscillations of a power system. The proposed control has been tested on th...

The subsynchronous resonance (SSR) of a double-fed induction generator (DFIG) and its suppression method are studied in this paper. SSR may be aroused by the interaction between series-compensated transmission lines. This paper proposes an expression electrical damping for assessing stability based on complex torque method. is derived linearizing DFIG model at operating point. When mechanical n...

Since NOx family, one of the most important causes of air pollution, is the primary source of acid rains, ozone layer depletion, and breathing disorders, mitigation of these pollutants is now a global concern. In the off-gases of internal combustion engines running with oxygen excess, non-thermal plasmas (NTPs) have an oxidative potential, which results in an effective conversion...

A synchronous GNSS generator spoofer aims at directly taking over the tracking loops of receiver with lowest possible spoofing to signal ratio (SSR) without forcing it lose lock. This paper investigates factors that affect success and their relationships. The necessary conditions for successful are obtained by deriving code error in presence analyzing effects SSR, synchronization errors, settin...
