Abstract

A new idea of using switching to enhance the transient stability of a transmission network is outlined conceptually and illustrated by means of a simple example where the technical implications are given. A realistic system is used to show the benefit of stabilizing switching for a long distance transmission scheme. Depending on the type of fault, where the most severe is the three phase short circuit, an increase of the maximum transmissible power of about 10 percent can be achieved by the switching scheme. The additional benefits of this scheme include reduced fault currents and minimized effects of unsuccessful line reclosure. This scheme also provides a possibility for applying other control devices in stability control, e.g. surge arresters, current limiters and MOS controlled thyristors in the future
