摘要

In this paper reduction of magnetic field generated by a single-circuit power line with a triangular arrangement of wires in a one-story residential old building by means of active silencing is proposed. The vector of the desired design parameters of the active silencing robust system, the components of which are the geometric parameters of the silencing windings and the desired parameters of the regulators for open and closed current control of the silencing windings calculated as vector minimax optimization problem. The vector objective function of this optimization problem calculated based on Biot-Savart’s law. The solution of this optimization problem calculated based on nonlinear multiswarm stochastic optimization algorithms. Results of experimental studies of robust system of active silencing for a magnetic field generated by a single-circuit power line with a triangular arrangement of wires in a one-story residential old building are given. Based on results of experimental studies the possibility of reducing of initial magnetic flux density level to the living safe level by means of active silencing shown.
