Fast-decoupled transient stability
Canadian Journal of Electrical and Computer Engineering, 1989Presents an improved method for computing transient stability using a fast-decoupled formulation of the transient energy function. The new formulation offers significant savings in computer time as compared to the existing Newton-Raphson formulation.

Transient statistics in stabilizing periodic orbits
Physical Review E, 1995The statistics of chaotic and periodic transient time intervals preceding the stabilization of a given periodic orbit have been experimentally studied in a ${\mathrm{CO}}_{2}$ laser with modulated losses, subjected to a small subharmonic perturbation.

In this chapter the reader has been introduced to the basic theory of electromechanical transients in power systems. The relative generator rotor motion has been described by the swing equation. The problem of transient stability has been explained on the basis of the well known but, especially from the tutorial point of view, still valuable equal-area

Controlling transient stability through line switching
2012 3rd IEEE PES Innovative Smart Grid Technologies Europe (ISGT Europe), 2012Smart transmission systems have introduced new possibilities of using topology control process for increasing power system dynamic security. Nowadays, in short term analysis, transmission topology is often treated as static and network reconfiguration is performed only for optimizing power flows and market performance.

A parallel transient stability limit search method for online transient stability assessment
2004 International Conference on Power System Technology, 2004. PowerCon 2004., 2005In this paper, a modified signal energy method called the envelope method will first be proposed to estimate the transient stability limit, and then a parallel envelope method is developed to speed up the limit search for online applications. A new weighting limit estimation formula is used for improving the estimation accuracy and minimizing of the ...

Transient stability of large aluminum stabilized superconductors
IEEE Transactions on Appiled Superconductivity, 1999Very large current composite superconductors have been considered and adopted to use in SMES coils and fusion applications, such as the Large Helical Device (LHD). These superconductors have large cross-sectional area of high purity aluminum stabilizer to improve their stability and to enhance the overall current density.

Online Transient Stability Assessment
2014With the advent of deregulation in the power industry and a lack of transmission investment, today’s power systems are operated much closer to their limits. Stressed system conditions mean that operators are faced with scenarios that never occurred in the past.

A Unified Scheme for Power System Transient Stability Simulation and Transient Stability Assessment
2019 IEEE 8th International Conference on Advanced Power System Automation and Protection (APAP), 2019Transient stability assessment (TSA) is critical for power system stability analysis and control. Among all efforts to achieve TSA, the transient stability simulation(TSS) plays a fundamental role. In this paper, a unified scheme is proposed for TSS and TSA of numerous power system transient scenarios. The scheme mainly consists of two parts, which are
