摘要：

Aim. Development of method for design a two -level active shielding system for an industrial frequency magnetic field based on a quasistatic model of a magnetic field generated by power line wires and compensating windings of an active shielding system, including coarse open and precise closed control. Methodology. At the first level rough control of the magnetic field in open -loop form is carried out based on a quasi -static model of a magnetic field generated by power line wires and compensating windings of an active shielding system. This design calculated based on the finite element calculations system COMSOL Multiphysics. At the second level, a stabilizing accurate control of the magnetic field is implemented in the form of a dynamic closed system containing, in addition plant, also power amplifiers and measuring devices of the system. This design calculated based on the calculations system MATLAB. Results. The results of theoretical and experimental studies of optimal two -level active shielding system of magnetic field in residential building from power transmission line with a << Barrel >> type arrangement of wires by means of active canceling with single compensating winding are presented. Originality. For the first time, the method for design a two -level active shielding system for an power frequency magnetic field based on a quasi -static model of a magnetic field generated by power line wires and compensating windings of an active shielding system, including coarse open and precise closed control is developed. Practical value. It is shown the possibility to reduce the level of magnetic field induction in residential building from power transmission line with a << Barrel >> type arrangement of wires by means of active canceling with single compensating winding with initial induction of 3.5 mu T to a safe level for the population adopted in Europe with an induction of 0.5 mu T.
