Drive system for a railway vehicle

Номер: GB0002611341A
Автор: JONAS ROSENGREN [GB]
Принадлежит:

A railway vehicle for travelling on routes with, and without, an external power supply infrastructure has a drive system with one or more external current collectors 13, one or more on-board generator units (GUs) 11 and one or more on-board energy storage systems (OBESSs) 12. The external current collectors obtain electrical power from the external power supply infrastructure. The GUs generate electrical power from combustion or oxidation of a fuel. The OBESSs store and output electrical energy. Traction motors 14a, 14b drive the railway vehicle using electrical power from the external current collector(s), the GU(s) and the OBESS(s), while a control system selectively controls the provision of power to the traction motors according to different driving modes. In a first driving mode, the power is provided from the external power supply infrastructure via the external current collector(s). In a second driving mode, the power is provided from the GU(s) assisted by the OBESS(s). In a third ...

Method of converting a train

Номер: GB0002611342A
Автор: JONAS ROSENGREN [GB]
Принадлежит:

A train with plural coupled cars and traction motors M distributed along the length of the train is converted from a pre-conversion state to a post-conversion state via one or more intermediate conversion states. In the pre-conversion state, some of the cars are power cars 1 with respective generator units (GUs) 2 which generate electrical power via combustion or oxidation of an on-board fuel to produce driving torques at the traction motors. In a post-conversion state, the generator units are replaced by respective on-board electrical energy storage systems (OBESSs) 11 for outputting electrical power to the traction motors. In the intermediate state(s), some of the power cars have GUs while others have OBESSs. A control system manages the power provided from the GUs and the OBESSs. In the pre-conversion state, or a preceding intermediate state, power cars with respective GUs for replacement are identified and a succeeding intermediate state is formed by replacing the respective GU in each ...
