An Energy-Efficient Control Algorithm and Simulation of Urban Rail Transit Systems

摘要

Energy efficiency of trains is an important and beneficial task. According to the research conducted on energy-efficient control both by domestic and international professionals, it is studied that the energy-efficient algorithms of the train of Urban Rail Transit with fixed running time. The algorithms adjust the maximal speed of whole lines and minimal speed of sections, which are used as the limited speeds, according to a given operational time. At the same time, using a forward calculating algorithm makes the best use of coasting to reduce times and time of traction and braking, which helps to decrease energy consumption. A computer simulation system has been developed, and some cases have been designed and analyzed for train movement under different times and different loco-tractions. It provides a method for optimizing real control model of the train of Urban Rail Transit.
