Tesyk Y. The creation of the adaptive instruments of metering quantity and quality indexes of electric power.

Object of research: processes of measuring of parameters of three-phase network of industrial frequency and reproducing of their rationed values in the extended ranges of changes of influencing factors on a background of the high levels of non-informative parameters.The purpose of research: development of fundamental statements and principles of construction of facilities of measuring and reproducing of parameters of amount and quality of electric power invariant to the influencing factors and non-informative parameters and creation on their basis of a few groups of measuring instruments.Methods of research: general methodical basis of work was become by the methods of the theoretical electrical engineering and informative-measuring technique with the use of mathematical facilities of rows of Fourier and matrix calculation. Basic statements of theoretical researches was tested by author experimentally on the developed adaptive measuring converters of power, energy, voltages, currents, indexes of quality and facilities of the metrological providing. Theoretical and practical results: the actual scientifically - the applied problem of creation of methods and principles of construction of facilities of measuring of parameters of electric power in the conditions of the frequent exceeding of non-informative parameters above informative and influence of a few groups of heterogeneous factors of influence in a wide dynamic range is decided. The new methods of reproducing of magnitudes of physical quantities which allowed to promote exactness and automatize the process of calibration of facilities of measuring parameters of amount and of indexes of quality of power are developed Object and degree of introduction: basic job performances are applied in serial industry on joint-stock company “ELVIN” and widely used in such industries of economy as Mintopenergo, Gosvodkhoz, Gospotrebstandart of Ukraine and enter-prises of mobile communication of «MTS» and «Kievstar». Scientific results are used in an educational process in NTUU «KPI». Efficiency of introduction: сonfirmed economic effect, got for one year from the use of multifunction meters, is made by 3 millions grn. Sphere of the use: informative-measuring systems and devices.
