PROSPECTS OF APPLICATION OF PHOTOELECTRIC SYSTEMS FOR ENERGY SUPPLY OF MAGNETOLEVITATION HIGH-SPEED TRANSPORT

Purpose. The purpose of the study is to substantiate the possibility of power supply of magnetolevitation high-speed ground transport from a distributed photovoltaic system. Modernization of the structure of the linear traction electric motor power supply system taking into account the features of energy generation, storage and distribution with the use of photovoltaic converters in it. Methodology. In the process of research, methods of analysis and synthesis were used to study the material of scientific publications on the assessment of the energy capabilities of a distributed photovoltaic power system, the theory of electric traction to assess energy costs for magnetolevitation transport, methods of the theory of electric machines, electrical engineering and electronics to modify the structure and parameters of the linear traction motor power supply system and the parameters of the motor itself. Results. Analysis of total insolation in different regions of Ukraine showed that during the calendar year, taking into account the orientation in space and the efficiency of solar photovoltaic panels, one can focus on the average generation figure of 50 kWh/m2∙year. At the same time, it was established that for movement at a steady speed of 500 km/h, a train with electrodynamic suspension, consisting of 10 cars with a total mass of 400 tons, consumes no more than 123 W∙h/t∙km. That is, under the specified conditions of solar energy supply, the electrical energy generated by 1 m2 of photovoltaic panels is enough to transport a maglev train weighing 400 tons for a distance of 1 m approximately 1 thousand times. The work outlines the structure and requirements for the power supply system of a linear traction electric motor using solar photovoltaic panels. Within the framework of the proposed structure of the linear traction motor power supply, the need to supply significant volumes of electrical energy over significant distances is eliminated, which contributes to a significant reduction in overall system losses, and the linear traction motor itself must have a short section of the stator winding, the length of which, taking into account dynamic stability and energy efficiency, varies within 0.5...2 m. Scientific novelty. The results obtained allow us to summarize the scientific basis for the development and improvement of the process of power supply of magnetic levitation ground transport. Practical significance. The proposed structure of the linear traction motor power supply of magnetic levitation transport from a distributed photovoltaic system acquires new properties, including its deep integration into the magnetic levitation transport control system, increased reliability and improved electromagnetic compatibility of its elements, and environmental friendliness.
