Electric power motor train unit grouping method more flexible

Abstract

The invention discloses an electric power motor train unit grouping method more flexible and belongs to the field of motor train unit grouping methods of electric power motor train unit vehicles based on electric power electronic transformers. According to the electric power motor train unit grouping method, carriages, except a train head and a train tail, of a motor train unit are provided with novel electric power electronic transformers which have the functions of transformers and also the functions of traction convertors and serve as novel power supply devices so that a traction drive system of the whole train can be more efficient, capable of better saving energy and lighter, the pantograph layout and the grouping method of basic motor train units are improved based on the fact, and the electric power motor train unit grouping method is more flexible. In addition, the industrial Ethernet serves as a new communication bus between all novel motor train carriages and a drive control system to replace a traditional rail vehicle MVB communication bus, the data transmission efficiency is improved, the congestion probability is reduced, the overall system reliability of coupling or decoupling of the motor train is improved, and safety of the train during running is improved.

Description

technical field [0001] The invention belongs to the field of an EMU marshalling method based on a novel power electronic transformer electric EMU vehicle, and in particular relates to a more flexible electric EMU marshalling method. Background technique [0002] Traditional ordinary trains only rely on the traction locomotive to provide traction power for the entire train. Except for the tractor locomotive, the rest of the trailer cars themselves do not have traction power. It is a power-concentrated traction technology. [0003] In contrast, the so-called EMU is to disperse and install the power devices on the traction locomotive and other carriages. Except for the traction locomotive, the rest of the carriages also have their own independent traction power devices. The rail passenger car of the traction device is called the motor car, which belongs to a kind of power dispersion traction technology. [0004] Existing power-distributed EMUs have generally adopted electric p...

Problems solved by technology

[0012] In order to solve the rigid and inflexible marshalling method of the existing EMUs, the basic form of the structure of the old electric power supply device seriously restricted the flexibility of the marshalling of the EMUs, and it was impossible to adapt to the high occupancy rate of the EMUs through a more flexible marshalling method , sometimes too low, and it is easy to cause the technical problem of waste of resources caused by the difference in transmission ratio. The present invention provides a more flexible method for marshalling EMUs
