Marenych K. Developement of the theory and principles of structural formation of the protective de-energization devices of modern mine electrotechnical complexes

Object of investigation is processes in a mine local electrotechnical complex, including states after supply voltage shutdown. Aim of research is increase of efficiency of operation of modern mine electrotechnical complexes on the basis of development of the theory and the principles of creation of means of a protective de-energization. Researches are based on the: general theory of electric chains, theory of transients in electric networks and motors, methods of a spatial vector and mathematical modeling. In dissertation the further development of methods of the analysis of conditions of electrotechnical complexes on the basis of the accounting of mutual influence of their distributed structural components, including sources of the return power streams. The offered principles of improvement of a mine local electrotechnical complex are the basic for application of a protective de-energization of the electric equipment by shutdown of the return power streams by the means, which adapted for use directly in accessions of stator of induction motors of consumers and not subordinated to operating influence of the external device of protection. Branch - the mine electrotechnical complexes.
