Feasibility study of starting modes of asynchronous drive to determine parameters of sources power systems supply unit
Technical sciences

Authors: Ratibor N. KONKIN graduated from Gubkin Russian State University of Oil and Gas in 2013. He is postgraduate student of the Department of Theoretical Electrical Engineering and Electrification of Oil and Gas Industry at Gubkin Russian State University of Oil and Gas (National Research University).

Abstract: A method of experimental determination of the parameters of power sources on the basis of the measurement data obtained from a variety of steady state and transient electric drive loads is considered. Computer modeling in MATLABE Simulink and analysis of the starting modes of asynchronous drive to study the engine EMF influence on the measured parameters were performed. The section of launcher waveform of currents and voltages of the asynchronous drive was determined. This can be used to calculate the parameters of power sources

Abstract: A new modification of the method of experimental determination of the equivalent parameters for power sources by measuring the values of currents, voltages and phase angles is considered. This can be used to determine the parameters in electric grids of any voltage. The modification of the method is of high accuracy in the range of load current small changes and does not require disconnecting the electrical load
