Description
Technical field
The present invention relates to rail traction control technology fields, more particularly to a kind of main line railway traction power supply state that is based on to believe
The train DAS (Driver Assistant System) of breath.
Background technology
Main line railway tractive power supply system in China's generally uses 25kV single phase industrial frequence alternating currents at present, is led to by traction substation
It crosses overhead contact line and provides power for traction for the electric locomotive in section.Since main line railway operation has, mileage is long, train is close
The features such as high is spent, therefore using traction substation at one is arranged at a certain distance along the line, institute is carried out by traction substation
Administer the train traction power supply in section.And due to alternating current phases difference between each traction substation, it can be by point without electricity
Phase region is electrically being separated.
Currently, the power supply mode of existing above-mentioned main line railway tractive power supply system brings two in actual application
A potential problem：First, when the train for being carried out at the same time traction in section is excessive, it can exceed that the maximum of traction substation is negative
Power is carried, power grid is caused to impact；Second is that train cross phase-separating section when, if the case where train operator does not know phase-separating section,
May then cause train to fail to enter phase-separating section with enough initial velocities, cause it is possible fall split-phase accident.
It is at present to take the side for increasing traction substation maximum load power and reserved power supply nargin for first problem more
Formula, this mode is with obvious effects, but cost is higher；For Second Problem, has part of the train at present and have automatic passing over of neutral section
Function, but train operator still has certain probability that error in judgement occurs in true train operation process, and train is caused to fall split-phase
The accident of (fail normally to be driven out to phase-separating section or even be parked in phase-separating section).
