Abstract

Underground cable performance with the qualitative aspects of the maximum cable temperature and ampacity are functions of installation conditions. Thus, this work presents an efficient methodology to improve the thermal performance of power cable with respect to optimize structural sizing involving the variables design of concrete duct bank dimensions. The methodology integrates the powerful features of the finite elements method (FEM) technique coupled with the self-adapting control parameters differential evolution algorithm (jDE) for handle various geometrical parameters in the complex surrounding installation case. Simulation results obtained by jDE were compared with in cases of the particle swarm optimization algorithm (PSO), momentum-type PSO and genetic algorithm. To optimize structural sizing, it was found that the performance of the concrete duct bank can be improved by jDE method and is better when comparing with the results from the other methods. Moreover, jDE can reduce sizing of the concrete duct bank with 17.48% of traditional design at the same ampacity of installation in noncomplex surrounding installation (normal case). This is important for reduce installation cost of concrete duct bank.
