摘要:
Provided is a high mobility railroad vehicle system configured to reciprocally carry out a direct drive between a non-electrically driven section and an electrically driven section without installing new facilities such as oil supply equipment and without considering distinction between the non-electrically and electrically driven sections. A railroad vehicle system is provided with an overall control apparatus to respectively control an external electric power supply means, an internal electric power supply means, an electricity storage means, electric power conversion means and a motor driving means. The railroad vehicle system judges or previously notifies as to whether the present driving railroad section is the electrically driven section or non-electrically driven section in accordance with driving position information received from a position information generation means such as a ground facility on a railroad equipped outside of the vehicle and a global positioning system (GPS). The system cuts off from an external electric power source in the non-electrically driven section and carries out a smooth shifting control in order to connect to the external electric power source in the electrically driven section.
摘要:
A system corresponding to a plurality of different power sources (overhead contact line, power generator driven by engine, and fuel cells) is proposed as a method of using an optimum power supply in an electrified route and a non-electrified route. However, since different power converters are necessary for each power source, there are problems of an increase in the weight of a multi-car train, a reduction in the degree of freedom in composing a multi-car train because a mounting space needs to be reserved, an increase in the maintenance cost, a reduction in the reliability caused by an increase in the number of components, and the like. Provided are: a power conversion circuit that includes AC input ends, the number of which corresponds to the maximum number of phases among a plurality of different AC power supplies, and that converts AC power to a direct current; and switching means for switching a connection state of the AC power supplies and the power conversion circuit, wherein the connection state is switched according to the power supplies.
