SYNTHESIS OF ACTIVE SHIELDING SYSTEMS OF POWER TRANSMISSION LINES MAGNETIC FIELD
According to the materials of scientific report at the meeting of the Presidium of the NAS of Ukraine
March 29, 2017
A new method of synthesis of active shielding systems of technogenic magnetic fields of high voltage power lines within a given region of space using controlled magnetic fields is developed. The synthesis consists in the solution of the problem of nonlinear multi-objective programming with constraints, in which computing the objective functions and constraints is based on Maxwell’s equations solutions. The problem is solved by stochastic multi-agent optimization with multiswarm particles. The synthesis method of active shielding close-loop systems of magnetic field on the developed layout of three-phase high voltage power lines is experimentally verified. The possibility of reducing the magnetic induction to the standard level for residential premises is experimentally confirmed.
Keywords: power transmission line, power frequency magnetic field, active shielding system, multi-objective synthesis, stochastic multi-agent optimization, experimental researches.
