Maintenance strategy focused on the specific consumption of diesel generators in sub-saharan countries: Case of National Electricity Company of Burkina Faso
Keywords:
Diesel thermal power plant, Specific consumption, Predictive maintenance, Burkina FasoAbstract
Sub-Saharan countries would mainly use thermal power plant whose Specific Consumption (SC) was relatively higher than the reference values provided by the manufacturers, which would contribute to the increase in electricity production costs. The aim of this study would be to propose a maintenance strategy which would aim to keep the SC according to the age of the generator at acceptable proportions according to the reference values provided by the manufacturers. The Ishikawa and Pareto diagrams were used to identify and analyze the causes of the variation in the SC of two large plants of the National Electricity Company of Burkina Faso. The results showed four major causes representing about 20% of the common causes which are 80% of the increase in SC in the thermal power plant of Kossodo and Komsilga, it would be : the poor quality of the fuels, lack of spare parts, inadequate maintenance practice, and poor fuel supply policy.
