The problem of improving the shielding efficiency of the magnetic field by overhead power lines (OPL) in residential buildings using a combined active and solid passive shielding system (CASPS) is considered. A method for the multiobjective design (MOD) of CASPS system under uncertainty is proposed to improve the shielding efficiency of overhead power-line magnetic fields. The MOD problem of CASPS is formulated as a geometric inverse problem of magnetostatics (GIPM). The problem is reduced to a vector minimax nonlinear programming problem (VMNPP), in which the components of the vector objective function (VOF) represent the resultant magnetic field in residential buildings. The VOF evaluation is performed by solving a geometric forward problem of magnetostatics (GFPM) using the finite element method (FEM) of three dimensions (3D) and the quasi-static formulation of Maxwell’s equations implemented in COMSOL Multiphysics software. The VMNPP is solved using a stochastic optimization algorithm inspired by the blood-sucking leeches behavior (BSLB) and based on Pareto-optimal solutions and binary preference relations. During the CASPS design process, the spatial coordinates of the solid passive shield and compensating windings, as well as the currents and phase angles of the active-shielding windings, are determined. The novelty of the proposed approach is the development of a method for the multiobjective design of a CASPS system that improves the reduction of power-frequency magnetic fields generated by OPL. Computer simulations and experimental investigations of the proposed shielding system for OPL of 3D MF model are presented. References 3, figures 3.
