ABSTRACT

The load on a power system network is increasing day by day without much enhancements in transmission and or generation capability. This causes the system to operate under stressed condition, even a small disturbance can l ....etc

Hi,
I am Jayasree.N ; M.Tech student from Osmania University. Iam working on a Project: Optimal location of FACTS devices for improvemnt of Voltage Stability ; In this regard, could any one please mail me the MATLAB code for L index?

I have done loadflow for 30 bus system in NR method; got the Y bus matrix for IEEE 30 bus system. Now how to separate the load and generator buses -- some one please let me know.
Thank You

Study of Evaluated a STATCOM Application for Voltage Stability by Dynamic PV Curves and Time Simulations
Abstract:
In this paper; voltage stability is evaluated by both
dynamic PV curves and titne-domain simiilations. considering the
combined a'ynamic contsol effects of a static compensator
(Sl:4TCOA.I) and transfosnier on-load-taps (OLT). The studied
system is heavily loaded at hvo locations and an 80 Mvar
SPITCOM is connected to impsore the voltage stability of entire
system for a contingency of a three-tesminal line o ....etc

Voltage Stability Improvement using Static Var Compensator in Power Systems

Abstract This paper investigates the effects of Static Var Compensator (SVC) on voltage stability of a power system. The functional structure for SVC built with a Thyristor Controlled Reactor (TCR) and its model are described. The model is based on representing the controller as variable impedance that changes with the firing angle of the TCR. A Power System Computer Aided Design /Electromagnetic Transients including DC (PSCAD/EMTDC) is used to ....etc

Abstract:
Voltage stability has recently become a challenging problem for many power systems. Voltage instability is one phenomenon that could happen in power system due to its stressed condition. The result would be the occurrence of voltage collapse which leads to total blackout to the whole system Investigation and online monitoring of power system stability have become vital factors to electric utility suppliers. Contingency screening and ranking (CS&R ....etc

VOLTAGE STABILITY



Abstract:

The impact that artificial neural network technique for the measurement of voltage stability using facts controllers is discussed here. For static voltage stability studies of a power system, the loading of the system is increased incrementally and slowly (in certain direction) to the point of voltage collapse. The MW-distance to this point is a good measure of system voltage stability limit. The voltage profile of the system ....etc
