摘要

The growth of freight traffic to the ports and border crossings of the Far East makes it necessary to significantly increase the carrying capacity for the railways of the eastern region of Russia. Trains with a mass of 6300 t cross through mountain passes with a traction of four-section locomotives in the stock front and rear end. Thus, the total capacity of the locomotives of only one train while moving along a steep ascent reaches 29 MW. The use of total capacity by locomotives at these locations in the modes of traction and regeneration braking imposes demanding requirements on the system of traction power supply. The automated monitoring system (AMS) of the traction substations has for several years of operation permitted accumulating a unique statistical basis for analysis of the operation modes of the traction power supply system in different conditions of handling of the trains and traffic density of trains. The data of the monitoring system includes all connections with current and voltage transformers. The monitoring system of the electrical parameters of the locomotive is synchronized and will be modified for operation according to the PMU standard. Thus, a complex electrified section will have the most complete set of measurements to investigate the operation of infrastructure while handling heavy trains. Continuous measurements enable one to tune out quickly protective equipment from increasing loads, allowing the influence to be determined of the balancing current on operation of protective systems and power losses in the system elements and making it possible to determine the necessity to apply the technologies of flexible alternating current transmission systems (FACTSs) in the power supply sector. The mathematical model of the traction power supply system based on measurements in the AMS permits controlling a large number of electrical parameters of its elements promptly identifying rapid degrading and differing from the normal ones.
