Abstract

Purpose. Experimental research of magnetic field sensors spatial arrangement influence on efficiency of closed loop active screening system by magnetic field of high voltage power lines developed a three-phase single-circuit high voltage power lines, creating a rotating magnetic field with the most complex space-time structure. Methodology. Optimal spatial arrangement of the magnetic field sensors is determined by solving the active magnetic field screening system synthesis problems with which the system provides the greatest efficiency of the active magnetic field shielding. Synthesis of active screening system is reduced to the problem of multi-criteria nonlinear programming with constraints in which calculation of the objective functions and constraints are carried out on the basis of Biot-Savart-Laplace law. The problem is solved by a stochastic multi-agent optimization by multiswarm of particles which can significantly reduce the time to solve it. Calculated arrangement of magnetic field sensors in a given space defined by the points at which the values of the corresponding components of the vector of magnetic induction take minimal values. Results. For the first time experimentally that changes in the position of the magnetic field sensors relative to their calculated position reduces the effectiveness of screening. The optimum position of the magnetic field sensors are the points at which the levels of the magnetic induction vector of projections orthogonal to the planes of the compensating coils are minimum values. Originality. For the first time invited to place sensors closed loop active screening system by magnetic field of high voltage power lines at the points where the calculated levels of corresponding projections of the magnetic induction vector orthogonal planes compensating windings are minimum values. Practical value. Practical recommendations for evidence-based selection of the spatial arrangement of the magnetic field sensors in a given area to ensure maximum efficiency of the active magnetic field screening system.
