Abstract

Purpose. At the stage of modernization and reconstruction of electrified railroads in Ukraine one should take into account the innovative development level of all electric supply subjects on the basis of advanced technologies. Determination the ways to increase the power supply reliability of electrified railways and reducing the accidents of the traction substation power equipment (TS). Methodology. For attainment a goal it’s studied the international experience on qualitative power supply of the electrical railways at the basis of the ideology of Smart Grid. It’s conducted a research of the major methods of technical servicing, repairing (TS and R) and diagnostics the traction substation devices of electrified railways. Findings. As a result of research it was concluded that the basis of the new methods of maintenance and repearing is analysis of the risks of operation of the weared equipment or equipment with some defects (maintenance of equipment on the basis of the actual technical condition). It’s also concluded that the conceptual definitions of Smart Grid point to the important role of smart grid technology to the economic development of the electrical system. Significant world experience of maintenance and repairing at the basis of the actual technical state shows the following general assessment of the effectiveness of this method: reducing maintenance costs by 75%, reducing the number of services up to 50%, reduction the number of failures by 70% in the first year. Originality. As a research and improvement result of the maintenance and repairing system of traction substations, the author has proposed the concept of maintenance and repairing intelligent system, monitoring and diagnostic of technical process equipment. The basic components of the system are proposed. It’s proposed a maintenance of the equipment of traction substation at the actual technical state with better resource parameters. In the normative document for maintenance and repairing of the equipment of traction substations, power points and sectioning posts of the electrified railways "CE-0024", this approach for organizing and conducting the maintenance and repairing of the TS is not considered. Practical value. Implementation of this system allows: to increase the main indicators of maintenance and repairing; decrease operating costs of the power equipment by using maintenance and repairing at a basis of the actual technical state; improve the reliability of equipment and the power supply system of TS of electrified railways, obtain economic benefit, and so on.
