A Probabilistic Approach to Classification of Transients in Power Systems
2006 Canadian Conference on Electrical and Computer Engineering, 2006This paper presents an in-depth study of classification of transients in power systems using two pattern classification methods, namely the maximum-likelihood, and the probabilistic neural networks. These methods, which stem from the Bayes rule, aim at estimating the underlying probability density functions that are required by the Bayes rule, but are ...

Computation of power system transients: Modeling portability
2009 IEEE Power & Energy Society General Meeting, 2009This panel paper presents research activities related to modeling portability between electromagnetic transients simulation programs. Although modern computer programs are provided with sophisticated graphical user interfaces, each program has its own modeling interface and model development methods.

Power-system transients caused by switching and faults
Electrical Engineering, 1939This paper summarizes the results of an investigation of transient voltages on power systems caused by switching and faults. The transient voltages on power systems as measured by the “klydonograph” are reviewed and compared with the flash-over values of transmission-line insulation. It is shown that the higher values of transient voltages are produced

On a new approach for the simulation of transients in power systems
Electric Power Systems Research, 2007This paper presents a new simulation tool named EMTP-RV. EMTP-RV is a completely new program with a new graphical user interface and a new computational engine. The simulation uses a new matrix formulation for computing load-flow, steady state and time-domain solutions.

Practical calculation of electrical transients on power systems
Electrical Engineering, 1943Solution of many power-circuit problems depends upon the magnitude, duration, and frequency of occurrence of transient voltages and currents produced by circuit changes. Circuit-opening or recovery-voltage transients are fundamental in the operation of interrupting devices and may be important from the standpoint of the dielectric strength of circuit ...

Power-Electronics-Enabled Transient Stabilization of Power Systems
2013Transient stability of electric energy grids is defined as the ability of the power system to remain in synchronism during large disturbances. If the grid is not equipped with controllers capable of transiently stabilizing system dynamics, large disturbances could cause protection to trigger disconnecting the equipment and leading further to cascading ...

Distributed Power Control for Transient Stability of Multimachine Power Systems
IEEE Journal on Emerging and Selected Topics in Circuits and Systems, 2017Transient stability is a key problem in power systems. Conventional methods enhancing the transient stability are always based on local information with a prior knowledge of an equilibrium point that may not be available for large disturbances. This paper puts forward a distributed power controller for improving transient stability of multimachine ...

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 ...

A solution to the problem of transient stability of multimachine power systems
2012 IEEE 51st IEEE Conference on Decision and Control (CDC), 2012In this paper it is shown that the controller design methodology recently introduced by the authors to stabilize non-globally feedback linearizable triangular systems solves the long-standing problem of transient stabilization of multimachine power systems with non-negligible transfer conductances.

A novel approach for the analysis of power systems transients
10th IEEE International Conference on Electronics, Circuits and Systems, 2003. ICECS 2003. Proceedings of the 2003, 2004The Electromagnetic Transient Program (EMTP) is extensively used for simulating fast transient effects in electric power systems. However, the difficulty of proper modeling of power systems remains a challenging problem for users. EMTP also requires a high level of technical expertise to apply models properly, but this expertise is normally ...
