Object of research - technogenic magnetic field of industrial frequency in indoors and at workplaces located near power lines. The purpose of the work is to develop a method of synthesis of the active magnetic field shielding system (AMFSS), which is created by a group of power lines, taking into account the limited possibilities of computer facilities. The analysis of known methods of synthesis of AMFSS of industrial frequency, which is generated by air lines. The scientific principles of the method of synthesis of AMFSS of industrial frequency, which is generated by the group of air lines. The verification of the developed method of synthesis of AMFSS based on the experiment was performed. The mathematical models of three-phase sources and magnetic actuators of active shielding systems of the technogenic magnetic field have been developed and the research of the adequacy of the developed models to the real processes has been carried out. The problem of synthesis of the system as an optimization problem is formulated and the method of solving the problem of optimal control is developed. Theoretical and experimental researches of the mathematical model of the system of active shielding of the technogenic magnetic field of the transmission line have been fulfilled. Experimental studies of physical models of AMFSS for premises and workplaces near power lines have been carried out. On the basis of the generalization of the results of theoretical and experimental research, the scientific basis for the synthesis of active magnetic field shielding systems with a frequency of 50 Hz was developed. Recommendations on the principles of building an active technogenic magnetic field shielding system for premises and workplaces near power lines have been developed. A new method for the synthesis of effective systems of active technogenic magnetic field shielding, generated by a group of high-voltage power transmission lines, was first developed and experimentally grounded in field conditions. The method is a scientific basis for the creation of the scientific foundations of the latest domestic technology for reducing the level of the magnetic field of industrial frequency in the residential areas located near the operating high-voltage air lines.
