Transient Stability Expert System
IEEE Power Engineering Review, 1989Expert system concepts are developed for use with power system stability studies, and proof of the concepts is provided in a prototype computer program. An analysis of the transient stability problem-solving process indicates that it is an iterative design procedure.

Transient stability control of TCSC [PDF]
2009 4th IEEE Conference on Industrial Electronics and Applications, 2009 This paper studies the strategy of thyristor controlled series compensation (TCSC) to damp power swing in interconnected systems. In interconnected network, TCSC must operate in response to inter-area main swing model, and its capacitive impedance must switch to the largest when the rotated speed deviation between equivalent centers of inertia is ...

Probabilistic on-line transient stability analysis
IEE Proceedings - Generation, Transmission and Distribution, 1999The feasibility of a probabilistic framework for real-time transient stability assessment (TSA) is explored. The main contribution of the probabilistic approach consists in a natural framework for dynamic security assessment (DSA). An advantage of the proposed approach is the enlargement of the time horizon for TSA, which allows contingency analysis to

Multimachine System Transient Stability Improvement using Transient Power System Stabilizers (TPSS)
IEEE Transactions on Energy Conversion, 1986Power system stabilizers (PSS) have been designed and installed [1,2] to improve the dynamic (smnall signal) response of multimachine systems. This paper presents the theory and test results for improving the transient (large disturbance) behaviour of a multimachine system by supplementing the conventional PSS with a transient power system stabilizer ...

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.

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 ...

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

Transient response and transient stability of power systems
Proceedings of the Institution of Electrical Engineers, 1968The paper presents a case for correlating transient response with transient-stability limit of power systems. An elementary power system provided with fast acting voltage regulators using various feedback signals is analysed in detail. The effect of varying regulator gains on transient response is investigated with the help of gain-locus diagrams on a ...

Sensitivity analysis for transient stability
IEE Proceedings - Generation, Transmission and Distribution, 1998The paper presents a method for security control of electric power systems effected by generation reallocation, determined by sensitivity analysis and optimisation. The model is developed considering the dynamic aspects of the network (transient stability).
