Minimization of Energy Consumption for Urban Rapid-Transit Traction

Abstract: Energy efficiency, planning, and traffic-control methods for urban rapid-transit trains are considered. The results of solving the problems of the energy-saving sequence of train-control modes when moving along the route at a given travel time, speed limits for trains with a regenerative-braking system, and energy-saving distribution of the travel time along the line routes are presented. An analysis of new-generation trains with regenerative braking in terms of energy saving is carried out. The results of the introduction of energy-saving control methods and trains with and without regenerative-braking systems according to the operating data for 2007–2019 are presented using the example of the Moscow subway. Power-efficient train dispatching algorithms for centralized intelligent control systems with compensated disturbances and postcontingency control algorithms are proposed and described. The viability and energy efficiency of the scheduled traffic without excessive timing when introducing centralized intelligent train-traffic-control systems is shown. © 2021, Allerton Press, Inc.
