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 ...

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

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 ...

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 ...

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 ...

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.

Protecting computer systems against power transients
IEEE Spectrum, 1990The sources of electrical transients, broadly interpreted as occurrences of any disturbance, either on the power line or the computer system's data line, are reviewed. Common transients are overvoltages due to lightning strikes, transients caused by switching sequences in the power system, and undervoltages which could be caused by a nearby start-up of
