Heuristic mathematical formulations and comprehensive algorithm for optimal decision making for power system cabling

Abstract

This paper proposes a novel method for an optimal cabling route; a combinatorial design algorithm through heuristic mathematical formulations to choose the optimal path when two or more physical paths are available. The best path, from an EMC point of view, can be chosen based upon various criteria, such as monetary cost minimization, voltage drop and quality (EMC) parameters. This paper initially provides numerical 2D and 3D resolutions of the problems of radiation generated by current sources. The proposed approach is based on the finite element method, associated with absorbing boundary conditions. The presented model makes it possible to consider wave propagation and its effect on heterogeneous mediums in transient, which can be applied in EMC for simulation of radiation. Initially, the formulations for electromagnetic modeling of the proposed problem are specified in detail. The simulation results are used for the cabling routes, with respect to undesirable field distribution in the specified regions. Based upon the aforementioned criteria, using an Analytical Hierarchy Process, the intelligent choice of optimal cabling routes can be achieved. Hence, there is a need for the proposed method to be successfully implemented on two different types of power system; a current injection system, and high voltage substation.

“…Also, k refers to the number of cables, and a1, a2 are correction factors according to the application where         . Shielding effectiveness (SE) is a parameter which defines as the ratio of the electric field or magnetic field strength at a cable or conductor before and after applying a shield [18].…”
