Energy management for hybrid energy railway vehicle

摘要

A drive control device for railway vehicle with high energy efficiency having DC power generating means and an electrical storage device and using power generated by at least one of the both means, in which energy management of the electrical storage device is carried out according to ever-changing route condition with a simpler configuration is provided. From a difference between kinetic energy calculated from a running speed of a vehicle and a reference kinetic energy calculated from reference speed information to a train location of the vehicle, an excess or shortage of a storage amount caused by a gradient condition of the route is estimated. Based on the estimated excess or shortage of the storage amount, a charging/discharging amount of the electrical storage device is adjusted.
