Rymar S. Transformers and reactors of equipment for highs harmonics current mitigation

Subject of inquiry are electromagnetic, power and thermal processes in dry mains transformers, autotransformers and chokes of devices of suppression of higher harmonics of a current. The purpose of operation is the evolution of the theory and methods of account of transformers and chokes of devices of suppression of higher harmonics of a current in view of processes in windings and magnetic conductors at higher harmonics of a current and a magnetic stream. Research techniques are founded on scientific positions of the theory of electric machines and theoretical electrical engineering: theories of optimization and methods of construction optimization mathematical models with distribution dependent and independent replaceable; theories and methods of account of an electromagnetic field and electromagnetic circuits, principle of duality magnetic and electric circuits, average geometrical distances; theories of an electromagnetic field in nonlinear medium; methods of boundary value problems of calorific conduction. Theoretical both practical results and novelty: is scientific applied problem of evolution of bases of the theory and heightening of exactitude of account of electromagnetic elements of devices of suppression of higher harmonics of a current - transformers, autotransformers and chokes, by the account of effect of wave harmonic components of a current and a magnetic stream in windings and magnetic conductors, principles of their development and projection is solved, that in aggregate brings in the essential contribution to evolution of the theory of electric machines and apparatuses. The designed methods allow to calculate, design and create in Ukraine modern competitive in the world market saving-energy the equipment which upgrades electric networks and diminishes losses in webs and the equipment. A subject and extent of a heading: results of operation, namely the theory and methods of account of transformers and chokes, are applied at projection of devices of suppression of higher harmonics of current E.O. Paton Electric Welding Institute of the NASU, Institute of Electrodynamics of the NASU, Company "Spectrum Ltd.", Company "KP ENRI Ltd.", Kyiv, Corporation "MIRUS International Inc.", of Toronto, can be used by the electrical engineering factories of Ukraine, in educational process on faculty of electromechanics National Technical University of Ukraine "Kyiv Polytechnic Institute" at preparation of masters and post-graduate students and at other engineering universities of Ukraine. Efficiency of a heading: heightening of exactitude of account of electromagnetic elements of devices of suppression of higher harmonics of a current at their projection. Sphere of use: electromechanics, transforming engineering.
