Description

The magnetic field of overhead lines and cable lines is the object of the research. The goal of the project is to develop the scientific principles of shielding technology for power frequency electromagnetic field created by overhead lines and cable lines. The following research methods are used: the finite element method, analytical models of power line electromagnetic field, optimization methods for shield construction. The analysis of known methods, means of shielding of electric and magnetic fields of overhead and cable lines, methods of their modeling and simulation is carried out within the project. The actual levels of magnetic and electric fields in residential buildings and, accordingly, the values of necessary shielding efficiency of shielding systems are determined and experimentally verified. As the result, the scientific principles of overhead line and cable line magnetic field reduction is developed in terms of the use of loop and combined shields. The method of synthesis of electromagnetic and magnetostatic shields for underground cable lines is developed. The scientific basis for determining the parameters and spatial configuration of a new type of electromagnetic shield - a grid shield, is developed. Grid shields provide as high shielding efficiency as traditional solid electromagnetic shields with a similar metal intensity, and at the same time grid shields are transparent for day light. The developed scientific principles of shielding technology will be implemented in the scientific work "Development of methods of passive shielding of the overhead line magnetic field". According to the results of the work, 9 scientific publications are prepared, 8 of which are indexed by the Scopus and Web of Science databases. The results of the project are reported at 4 international scientific and technical conferences.
