Direct Detection of Voltage Collapse in Electrical Power System
Tikrit Journal of Engineering Sciences, 2011 Voltage stability is indeed a dynamic problem. Dynamic analysis is important for better understanding of voltage instability process. In this work an analysis for voltage stability from bifurcation and voltage collapse point of view based on a center ...

Voltage collapse in power systems [PDF]
IEEE Circuits and Devices Magazine, 1992 The stages of a voltage collapse in a power system are described. Circuit and system techniques for analyzing voltage collapse that relate it to the changing number of solutions for the power-flow equations, due to slow changes in system parameters are presented. It is shown that to fully analyze voltage collapse for small- and large-disturbance cases,

Voltage collapse mechanism based on system circuit and its solution manifolds [PDF]
, 2001 The problem of voltage collapse in the power system occurs when the load parameter exceeds some critical value. The critical operation point is known as the nose point in P-V curve.

Simulation of voltage collapse
International Journal of Electrical Power & Energy Systems, 1993 The article analyses the mechanisms of voltage collapse and reaches the conclusion that it is necessary to make use of detailed simulations in order to study real cases. The performance levels required from the simulation programs are established. A summary description of the Eurostag code highlights the program's algorithmic bases.

Estimating the Collapse Point of a Transmission Line in a Developing Power Systems
Arid Zone Journal of Engineering, Technology and Environment, 2023 The trouble with a developing national grid is compounded by the fact that the power system supplies power to a vast number of loads which is fed by a number of generating units sometimes far from the load centers.

Random load fluctuations and collapse probability of a power system operating near codimension 1 saddle-node bifurcation [PDF]
, 2012 For a power system operating in the vicinity of the power transfer limit of its transmission system, effect of stochastic fluctuations of power loads can become critical as a sufficiently strong such fluctuation may activate voltage instability and lead ...

Enhancement Voltage Stability of the Iraqi Power Grid Using Shunt FACTs Devices [PDF]
Engineering and Technology Journal, 2016 Due to raise in demand, the transmission system becomes more exhausted, which in turn, forces the system to be more susceptible to voltage instability. The aim of this research is to study the enhancement in voltage stability margin by installation the ...
