Interactions between regulating equipments in voltage instability environment

Abstract

Interactions among control equiprents is a cumbersome 'and difficult to solve problem in voltage instability environment. This paper presents a simple and qualitative criterion concerning the oscillatory/ nonoscillatory behaviour of two units of OLW's with time delays. The correspondence between the multiple .> load f l m solutions and a set of SEP & LTEP's has been made clear. Extension and applicability of the propsed methcd was also suggested.
