Abstract

Power consumption estimation in municipal electric transport for increasing the efficiency of using an existing power supply system in modern conditions. The electric power supply systems of the tram and trolleybus, which were built and used for many years in Ukraine, were designed according to the norms and data determined by city planning, the rolling stock number, its characteristics, route features, etc. In recent years, the passenger traffic parameters, number and characteristics of rolling stock have changed considerably, therefore, the actual solution of the issues of already existing electricity supply system most efficient use in the current conditions of topical issue management.

On data of the actual electricity consumption on municipal electric transport, hydrometeorological center, tram enterprises, traffic conditions on routes, received an estimation of the use electricity supply system existing efficiency for appropriate measures was carried out. The method of specific energy consumption determination by separate power areas, determined by the location of traction substations, taking into account the types of rolling stock and their traffic conditions, is proposed. The use of a universal indicator of specific energy consumption as an estimate of the energy consumption level makes it possible to compare the level of electricity supply system components efficiency.

On data of the research the energy expenditures spent components of use efficiency evaluation, the following solutions may be proposed: a new location of stopping points with the elimination of irrationally located and low passenger traffic while maintaining the average passenger travel time; rational distribution of rolling stock on routes; change of the motor transport scheme on the lines of municipal electric transport, the elimination of a traffic lights number, or the equipment of moving parts equipment with right-priority pass; change of the power supply scheme, the use of amplifying cables, wires, reconstruction of traction substations to reduce voltage losses, etc. The method of estimating energy consumption on the basis of comparison of specific energy consumption taking into account traffic conditions is improved. The proposed methodology allows us to develop grounded measures for increasing the efficiency of electric power supply systems in municipal electric transport in modern conditions.
