Abstract
Purpose. Development of a method of synthesis of systems of active screening of technogenic power frequency magnetic fields within a given region of space, as well as the synthesis and performance evaluation systems synthesized active shielding magnetic field. Methodology. A mathematical model for calculating the components of the magnetic field created by current distributors power line generator or electrical conductors power and control windings magnetic executive bodies on the basis of the law of Biot - Savart - Laplace. Conductors are taken as a set of elementary sections conductors, which allows to calculate the magnetic field conductors of any shape that is different from the ideal straight lines or rectangles, and in particular, to consider the slack conductors power line power lines. Results. Synthesis of active shielding systems for technogenic power frequency magnetic fields is reduced to the solution of a nonlinear programming problem with constraints, which computation of the objective function and constraints is performed based on the Biot - Savart - Laplace law. Formulated nonlinear programming problem is solved by using the multiextremal and stochastic multi-agent method based on particle swarm optimization, in which the particle swarm move in a multidimensional search space. Originality. First developed a method for the synthesis of active shielding systems for technogenic power frequency magnetic fields using controlled source of the magnetic field by solving a nonlinear programming problem with constraints based on stochastic particle swarm optimization of multi-agent. Practical value. Examples of synthesis of systems of active shielding technogenic power frequency magnetic fields and high efficiency of the synthesized systems.
