Lazaryan popup.description2  Object of research ̶ electromagnetic processes in power circuits of traction substations of direct and alternating current in the conditions of the organization and introduction of high-speed movement of trains. The purpose of the work is to develop a method and identification models of TS, taking into account the probabilistic stochastic nature of voltages and currents of TS and which allow to predict electromagnetic processes in the traction power supply system at the stage of development and implementation of high-speed trains. Research methods ̶ theory of power supply of electrified railways, theory of random processes and methods of their processing, methods of system identification, theory of electric circuits with non-sinusoidal electric quantities, methods of solving integral equations, Laplace operator method of calculation of transients. In the course of researches in the conditions of real operation of one of traction substations of the Odessa railway temporary monitoring of primary (to TS) and on TS tires of stochastic processes of tension and current is carried out. Their probabilistic-statistical processing and correlation analysis are performed. Theoretical preconditions for the construction of identification models are presented, for which the Wiener-Hopf equation is obtained and methods for its solution are proposed, as a result of which the weight function is obtained as an adequate exhaustive model of TS. Statistical and deterministic dynamic identification models of DC and AC TS have been developed, which are based on the solution of the Wiener-Hopf correlation equation and on the inverse Laplace transform of the transfer function. Numerical calculations of weight functions as identification models of a number of TS of Odessa and Prydniprovska railways are performed. The adequacy and predictive capabilities of the developed models were checked by calculating the established values ​​of output (to TS) voltages and currents at certain voltage valu Product Description popup.authors DANILOV OLEKSII A popup.nrat_date 2021-01-02 Close
