Voltage Collapse Mechanism in Electric Power Systems
The heart of the voltage stability problem is the voltage drop that occurs when the power system experiences a heavy load, and one serious type of voltage instability is voltage collapse. In this paper, a mechanism of the dynamic phenomenon of voltage collapse is presented from the physical point of view. It is shown that an iterative reaction of voltage drop between a dynamic load and the syst...
متن کاملCoordinated Voltage Control in Electric Power Systems
This thesis deals with various aspects of coordinated voltage control in electric power systems. It consists of an introduction and six papers. The introduction contains a summary of the thesis and tutorials on voltage control and the search methods that have been applied. The first part deals with the coordination of cascaded tap changers in radial distribution feeders. Poor coordination cause...
متن کاملReactive Power and Voltage Control Issues in Electric Power Systems
This chapter was prepared primarily for "non power" engineers to introduce reactive power and voltage control concepts, and to identify several issues that remain as research challenges in this area. It begins with basic definitions and information on reactive power, and then focuses on problems that have been known for many years and have surfaced recently in power system operations. These pro...
متن کاملDecision trees and transient stability of electric power systems
A general inductive inference method is proposed and applied to the automatic building of decision trees for the transient stability assessment of power systems. On the basis of large sets of simulations, the essential features of the method are analysed and illustrated. Al~lraet-An inductive inference method for the automatic building of decision trees is investigated. Among its various tasks,...
متن کاملRelationships between voltage and angle stability of power systems
This paper discusses modelling and theoretical issues associated with voltage and angle stability of power systems. A time-scale decomposition is performed to illustrate how the critical modes can be identified with reduced-order models and the bifurcation phenomena can be explained with these low order models. Examples are given for single and muhimachine systems. Copyright © 1996 Elsevier Sci...
