Повний текст джерелаThesis for the degree of Doctor of Engineering in specialty 05.22.09 "Electric transport " - National Technical University "Kharkiv Polytechnic Institute" MES of Ukraine, Kharkov, 2018. The thesis is devoted to the creation of scientific foundations for the selection of optimal parameters and operating modes for cooling systems for asynchronous traction motors of electric transport. An algorithm for solving the Hamilton-Jacobi-Bellman equation for the problem of the motion of an electric stock on a section of a track with a given profile and a traffic schedule is developed. That makes it possible to create an expert control system for motion. Features of this algorithm is the use of penalty functions to describe the restrictions imposed by the traffic schedule: the train reaches the destination point for a given driving time, the speed limit on the sections of the track, and the absence of train idle time during the movement. A single approach to penalty functions is also applied to introduce constraints on the adhesion. This approach allows to reduce significantly the costs of the estimated time and to simplify the procedures for calculating energy costs. A mathematical model is created to determine the efficiency of the traction drive. The model includes the determination of the main losses in an asynchronous traction motor, taking into account the saturation of the magnetic system, which is determined by the results of solving a recurrent nonlinear equation. Also, the model takes into account losses from higher harmonic stresses in copper and steel, mechanical and additional losses. The developed model takes into account static and dynamic losses in IGBT transistors and diodes of a semiconductor converter. A method for optimizing the parameters and operating modes of cooling systems for asynchronous traction motors of the electric stock is developed. It consists of the following main stages: determination of the optimum mode of the traction drive operation on the basis of the proposed expression of its efficiency; determination of optimum modes of movement of the electric stock by the criterion of minimum costs; solution of the traction problem of motion on a section of the track with a specified traffic schedule and the track profile, as well as the determination of the dependence of the change in losses in the elements of asynchronous traction engines in time; choice of parameters and operation modes of cooling systems for asynchronous traction motors, which determine the efficiency of the cooling and ventilation system of the electric stock; solution of the problem of relative minimization of the cooling system for asynchronous traction motors with a modernized criterion of economic efficiency based on the Weil method on the generalized golden section and the problem of analyzing the ventilation and cooling system of traction motors, which is based on the mathematical model of thermal motor conditions by the generalized equivalent thermal scheme.

Kharkiv, 2020. The dissertation is devoted to creation of scientific bases of choice of optimum parameters and modes of operation of the system of reactive power compensation on electric locomotives operating on alternating current. The factors that have the greatest impact on the quality of traction power supply from the side of the electric rolling stock of alternating current are analyzed. Factors that cause the greatest distortion of the voltage form of the catenary include higher harmonic components, which are introduced into the traction power supply system by electric rolling stock. It is shown that such factors as poor current collection, passage of electric rolling stock of the feeder zone, the presence of several units of electric rolling stock in one feeder zone, modes of operation of electric rolling stock lead to the fact that the process of voltage change in the catenary is nondeterministic for the analysis of the spectral composition of the traction current of an electric locomotive, the application of classical Fourier transform methods is incorrect. Analysis of circuit solutions for compensation of reactive power consumed by electric rolling stock of alternating current showed that to date the most optimal solution is the use of hybrid compensators. In such compensators, the passive part reduces the phase shift between the voltage of the secondary winding of the traction transformer and the traction current, and the active part removes the higher harmonic components of the traction current. The active part of the hybrid compensator is a stand-alone current inverter and an inverter control system. The control system performs spectral analysis of the traction current, forms an algorithm for the generation of autonomous inverter higher harmonics, the same amplitude but antiphase to the higher harmonics of the traction current. Existing control systems use Fourier transform methods to determine the spectral components of the traction current, but in real operating conditions of the electric rolling stock they are incorrect. It is proposed to apply the methods of correlation spectral analysis to determine the spectral components of the traction current. Mathematical and program-oriented models of work of traction and auxiliary drive of an electric locomotive of an alternating current (on the example of the locomotive VL-80k) have been created. The unique features of these models are the ability to take into account the mutual influence of the traction and auxiliary drives and the operating modes of electric locomotives. The technique of calculating the parameters of asynchronous motors for asymmetrical stator windings has been improved. The relationship between such parameters as the scattering inductance and the mutual inductance with the geometric parameters of the windings is shown. This technique was used to create a mathematical model for the drive of auxiliary machines, in particular for the simulation of the phase splitter. It is proposed to investigate electrodynamic processes in auxiliary machine actuators in steady state operation, to replace the phase splitter with an asymmetrical voltage system that feeds the motors of fans. The mutual influence of traction actuator and auxiliary motors operation was investigated. The results of the study made it possible to clarify the spectral composition of the current in the traction and auxiliary drive circuits. The use of a hybrid reactive power compensator in traction drive circuits is substantiated. The elements of the passive and active part of the compensator are calculated. A control system for the active part of the reactive power compensator has been developed, which is based on the block of determination of harmonic components of traction current and suppression in the current spectrum of zero and higher harmonic components. A new scientific approach to the determination of the spectral components of the traction current is proposed. It is based on the application of the linear prediction method of Levinson-Darbin. This approach allows to take into account the random nature of the voltage and, as a consequence, the traction current, and to adapt the work of the compensator to the voltage of the contact network. The application of this approach also allows taking into account such factors as the nature of the mode of operation of the electric locomotive, the passage of the boundaries of the sections of the contact network, etc. Adjusted mathematical model of traction actuator when using of reactive power compensator, calculated and constructed amplitude-frequency and phase-frequency spectral characteristics of voltage and current on the traction winding of the transformer. The power factor of the upgraded traction actuator is calculated. The justified is use of a static converter instead of a phase splitter in the auxiliary drive power supply system. The system of mathematical modeling of the auxiliary drive of the electric locomotive is executed; the amplitude-frequency and phasefrequency spectral characteristics of the voltage on the winding of the transformer and the current flowing through the winding of its own needs are calculated and constructed. The power factor of the upgraded auxiliary actuator is calculated. The losses of active and full power in the traction and auxiliary drives of the locomotive were calculated before and after the modernization. The dependences of the efficiency and the power factor of the drives before and after the modernization were calculated. The results obtained indicate that the efficiency of the traction drive after the use of the compensator decreased by 0,6% a factor and the power factor increased by 3,2%. Auxiliary drive efficiency after upgrading increased by 1,5%, and power factor increased by 26,4%. The developed scientific provisions are an effective tool for modernization of the existing fleet of electric locomotives of the VL-80t and VL-80k series and the creation of a new electric rolling stock of railways. The results of the dissertation were implemented at the Scientific Research Design and Engineering Institute of Railway Transport of OJSC "Ukrzaliznytsya" (Kyiv), SE "Ukrainian Research Institute of Carriage" (Kremenchuk) and in the educational process of the State University of Infrastructure and Technology (Kyiv).

The analysis of circuit solutions for the compensation of reactive power consumed by the electric rolling stock of alternating current showed that to date the most optimal solution is the use of hybrid reactive power compensators (НRPС). In such compensators, the passive part reduces the phase shift between the voltage of the secondary winding of the traction transformer and the traction current, the active part - removes the higher harmonic components of the traction current. The passive part of the НRPС is LC-filter, and the active stand-alone current inverter and control system of inverter. The control system of inverter performs spectral analysis of the traction current, forms an algorithm for the generation of autonomous inverter higher harmonics, the same amplitude but antiphase to the higher harmonics of the traction current.

The elements of the passive and active parts of НRPС are calculated. A control system for the active part of the НRPС has been developed, the basis of which is a unit for determining the harmonic components of the traction current and removing zero and higher harmonic components from the current spectrum. A new approach to determining the spectral components of traction current is proposed. This approach is based on the application of the Levinson-Darbin linear prediction method.

The application of this approach also allows taking into account such factors as the nature of the mode of operation of the electric locomotive, the passage of the boundaries of the catenary, and so on. The mathematical model of the traction drive when using НRPС is corrected, the amplitude-frequency and phase-frequency spectral characteristics of the voltage and current of the traction winding of the transformer are calculated and constructed. The power factor of the modernized traction drive is calculated. The use of a static converter instead of a phase breaker in the power supply system of auxiliary machines is substantiated.
