АНАЛІЗ ПЕРСПЕКТИВНИХ ТЕХНОЛОГІЙ ПІДВИЩЕННЯ ЕНЕРГОЕФЕКТИВНОСТІ СИСТЕМ ЕЛЕКТРИЧНОЇ ТЯГИ ВАГОНІВ МЕТРОПОЛІТЕНУ

Abstract. The work includes a comprehensive analysis of promising technologies for increasing the efficiency of the electric traction system of metros. It is noted that the introduction of energy-efficient systems on metro rolling stock can significantly reduce electricity consumption for traction – up to 40 % using recuperation systems and another 10-20 % using energy storage systems. Microprocessor control systems can also help reduce electricity consumption by 10 %. The use of such systems is a promising direction for energy saving on metro rolling stock due to lower capital investments. Such systems can be installed on various types of rolling stock and will help improve traffic safety, stabilize the traffic schedule and make it easier for train drivers to control the train.
