Experimental wind power and photovoltaic plants as a basis for researching to use renewable energy sources in the power supply systems for non-traction consumers

Abstract

Purpose. Describe the tools used by the authors for experimental research on the possibilities of using renewable energy sources in the power supply systems of non-traction consumers of railway transport. The methodology of research is based on modern methods of computational mathematics, statistics and information analysis using modern computer technology. Findings. To date, there is no comprehensive approach and specific reasonable measures for the introduction of re-newable energy sources in the energy supply of non-traction consumers. The article presents examples of the introduction of renewable energy sources in the power supply systems of railways abroad. It is noted that when using different renewable energy sources in the power supply systems of non-traction consumers, it is necessary to have a volume of statistical information to determine their technical and economic indicators. The classification of wind power plants with a horizontal axis is given. The schematic diagram and general view of the developed experimental wind power plant are given. The schematic diagram and general view of the developed experimental photovoltaic plant are given. The equipment used for research of wind flow and intensity of solar radiation in places of possible location of wind power or photovoltaic installations is considered. The presented experimental wind power and photovoltaic plants, which serve for a comprehensive study of the possibilities of using wind and solar sources in the power supply systems of non-traction consumers, are generalized and allow to clarify the necessary data for decision making. The originality is the introduction of renewable energy sources in the power supply system of non-traction consumers of railway transport. Practical implications. The use of additional renewable energy sources to supply non-traction consumers minimizes electricity consumption.
