Problems Raised by the Interconnexion of National Electric Power Supply Networks

Abstract

In the developing countries electricity supply is almost invariably organized on a local basis. This is due to the concentration of consuming centers in certain limited areas and to the relatively high cost of transmission lines. Accordingly, the interconnexion of these local networks and, at a later stage, of the national transmission networks is perhaps not of great immediate importance. Nevertheless, interconnexion represents the logical final step in any harmonious programme for the development of the electric power supply system of an area. In this connexion, the experience acquired by European countries since the end of the Second World War could serve as a guide since these countries electricity supply networks are now interconnected.
