摘要

目标考虑通过对位于现有典型架空电线附近的住宅旧建筑进行主动屏蔽,将磁场感应降低到现代卫生标准的水平。考虑了单层和多层建筑内部磁场的主动屏蔽。在设计过程中,确定了屏蔽绕组的数量、配置、空间布置以及屏蔽绕组中的电流。方法论将有源屏蔽系统的设计问题简化为求解极小极大矢量优化问题。在这个极小极大问题中,目标函数的向量是根据毕奥-萨伐特定律计算的。这个问题的解决方案是基于多智能体优化算法。后果介绍了单层和多层建筑内各种架空电力线产生的磁场的主动屏蔽系统的理论和实验研究结果。独创性显示了将屏蔽空间内初始磁场的感应降低到卫生标准水平的可能性。实用价值。从实际实施的角度,给出了不同楼层住宅内各种架空电力线产生的磁场主动屏蔽系统屏蔽绕组的数量和空间布置的合理选择。

Reduction of magnetic field level in residential old buildings from overhead power lines by means of active screening
Aim. Reduction of the magnetic field induction to the level of modern sanitary standards by means of active screening in residential old buildings which are located near existing typical overhead power lines are considered. Active shielding of the magnetic field inside a single-storey and multi-storey building is considered. During the design the number, configurations, spatial arrangement of the shielding windings, as well as the currents in the shielding windings were determined. Methodology. The design problem for the system of active shielding reduced to solving the minimax vector optimization problem. The vector of objective function in this minimax problem is calculated based on Biot-Savart's law. The solution of this problem is based on multi-agent optimization algorithms. Results. The results of theoretical and experimental studies of the systems of active shielding of the magnetic field generated by various overhead power lines inside a single and multi-storey building are presented. Originality. The possibility of reducing the induction of the initial magnetic field inside the shielded space to the level of sanitary standards is shown. Practical value. From the point of view of the practical implementation for a reasonable choice of the number and spatial arrangement of shielding windings of systems for active shielding of the magnetic field generated by various overhead power lines inside residential buildings of different storey’s are given.
