The scheduling of these tasks is subject to topological, economical and electrical constraints. By is mature, problem modelling is a hard task. Traditional methods have great difficulties on dealing with such complex problems. Constraint Logic Programming (CLP) has great modelling capacities and so it seams the right tool to deal with them. On this work, we propose a new CLP method to solve the problem. This method deals with the electrical constraints on a different manner, avoiding many load flow calculations by means of performing what is known as contingency analysis on electrical networks, reducing computational complexity and speeding the calculations.engDistribution NetworksMaintenance SchedulingCombinatorial OptimisationElectrical ConstraintsConstraint Logic ProgrammingContingency Analysisconference paper
