Train controlling method and controller for railway vehicle

Abstract

The present invention provides an energy saving operation method of rolling stock in which various losses are minimized while ensuring traveling required for a composition of train, and to provide a rolling stock controller. The rolling stock controller for controlling a train including a plurality of vehicles having a power unit and a power unit controller in one composition comprises a means for delivering a driving force command value Iut and a unit open command Iuc or a unit open release command Iucr individually to each power unit 22, and a means for comparing the maximum driving force of each power unit with a driving force required at that moment in time. When a decision is made that the driving force required at that moment in time is lower than the sum of maximum driving force of driving units being operated, the unit open command for stopping operation of the power unit is delivered to each power unit stepwise.

Description

technical field [0001] The present invention relates to a control method and a control device of a power distributed railway vehicle, and relates to a train control method and a control device for a railway vehicle for instructing operation / stop of each power unit for each power unit. Background technique [0002] In conventional railway vehicles, the unit disconnection method of releasing the power unit from the control system and not operating is adopted in order to separate the failed power unit from the control of the entire train when a power unit fails. In this method, when a specific power unit repeatedly repeats the protection action, it is inferred that there is some abnormality inside the power unit, and the driver operates the unit cut-off switch set on the workbench. Thereafter, such a structure as the power unit may not be used. In this case, if the driver operates the traction wrench (handle) and brake wrench (handle) once an instruction to cut off the unit is...

AI Technical Summary

Problems solved by technology

At this time, even if the driving force of each power unit is low, due to the operation of the machine, current flows through the elements. In order to output AC power with less high-order harmonics and less distortion in the motor 25, the elements need to be switched at high speed. Movement generates heat, which is also the main cause of loss and efficiency reduction

In addition, there are elements that become the basic loss, such as the loss caused by the operation of the cooling system device used to cool the machine, the core loss of the transformer that is always used to apply power, etc.
