ABSTRACT: The electrical energy produced must be consumed at
the same time, hence the need to achieve a balance between supply and demand.
Therefore, the production, transport, and distribution systems together
constitute an electricity network. The distribution networks are designed to
deliver energy to consumers. Unacceptable voltage drops are observed in the
distribution networks of developing countries such as Burkina Faso. A study was
carried out on the distribution network of the city of Bobo-Dioulasso in
Burkina Faso. It allowed for experimentation with the “Megger MPQ1000” network
analyzer to evaluate the quality of the voltage supplied to households. To this
end, tests were carried out in a public distribution station and at a few
subscribers in the Sarfalao district of the city of Bobo-Dioulasso. These tests
were used to assess the percentage of voltage drops. These values, which are
higher than 8% of the nominal voltage, are not regulatory. The load curves of
the consumers in the district were also drawn. Indeed, the period of the high
load is between 19:00 and 23:00 Local Time (LT), while the period of the medium and low load is
between 00:00 and 18:00 LT.
