ABSTRACT: Electricity
being a basic national infrastructure for a country, its security, reliability
and quality are the most important parameters for the network managers. Several
methods are generally used to improve the voltage quality more and more.
However, most of the means implemented depend on external factors independent
of the network managers or require huge regular financial resources. The method
used in this paper is the loopback, applied to the Southern Interconnected Grid
(SIG) of Cameroon, which is the largest network
in the country. The procedure used takes into account nodes experiencing huge
voltage drops and network constraints. The chosen loopback scenario
results in a clear improvement of the voltage plan in this network, and also a
discharge of the transformers, a considerable decongestion of the lines, a
reduction of the power losses and a significant reduction of the thermal
placement used for improvement of the voltage profile.
