Embodiment
The invention will be further described below in conjunction with the accompanying drawings.Following examples are only used for clearly illustrating the present invention
Technical scheme, and can not be limited the scope of the invention with this.
As shown in figure 1, a kind of high-speed railway traction power supply gets over area's fault distance-finding method, it is specific as follows：
1) as shown in Fig. 2 by traction substation, AT and subregion range unit communicated by Ethernet or E1 it is mutual
Connection, and on send data to dispatching terminal.
2) when traction power supply mode is switched to over-zone feeding mode by normal power supply mode, positioned at point of current supply arm
Area's Suo Neiyue areas disconnecting switch is changed to closing position by open position, and subregion sends over-zone feeding and alerted to dispatching terminal,
After over-zone feeding acknowledged alarm (generally manual confirmation), dispatching terminal by be remotely controlled positioned at traction substation, AT institutes and subregion
Range unit gets over the soft pressing plate input in area, and reads over-zone feeding operational factor.
Conversely, when traction power supply mode is switched to normal power supply mode by over-zone feeding mode, positioned at current supply arm
Subregion Suo Neiyue area's disconnecting switch open position is changed to by closing position, subregion sends normal power supply and alerted to scheduling
End, after normal power supply acknowledged alarm, dispatching terminal by be remotely controlled positioned at traction substation, AT with subregion range unit to get over area soft
Pressing plate exits, and reads normal power supply operational factor.
High-speed railway ranging parameters on one supply arm include some groups of parameters, be up to 15 groups of parameters, every group of parameter
Include normal power supply operational factor and over-zone feeding operational factor, when traction power supply mode is normal power supply mode, ranging
Device reads normal power supply operational factor, and when traction power supply mode is over-zone feeding mode, range unit reads over-zone feeding
Operational factor.As shown in Table 1, normal power supply operational factor includes normal power supply messaging parameter, normal power supply protection definite value and just
Often power supply ranging parameters；Over-zone feeding operational factor includes over-zone feeding messaging parameter, over-zone feeding protection definite value and more area supplies
Electric ranging parameters.As shown in Table 2, normal power supply messaging parameter include this side IP address, offside IP address, this side plant stand number and
Offside plant stand number；Over-zone feeding messaging parameter include more this side IP address of area, more area's offside IP address, more this side plant stand number of area and
More area's offside plant stand number.
The parameter list of table one
The communication parameter list of table two
Range unit read parameter process be：Range unit moves back according to the throwing of the soft pressing plate in more area, corresponding to automatic reading
Messaging parameter, shield definite value and ranging parameters are simultaneously restarted automatically, write messaging parameter, shield definite value and ranging parameters in restarting process
Specific storage region.
As shown in figure 3, under normal power supply state, draw institute A, AT institute A and subregion forms supply arm A, traction institute B, AT
Institute B forms supply arm B with subregion.Be now placed in drawing institute A, AT institute A and subregion range unit by Ethernet or
E1 passages interconnect, wherein, traction institute A, AT institute A, subregion institute, traction institute B and AT institute B range unit communicate according to normal power supply
This side plant stand number, offside plant stand number, this side IP address in parameter are communicated with offside IP address, and range unit uses normal
Power supply protection definite value and normal power supply ranging parameters.
When using over-zone feeding mode, traction institute A, subregion institute and AT institutes B composition supply arms.Now subregion can pass through
In more separate and leave off position and judge whether to be in over-zone feeding state, if meeting condition, dispatching terminal automatic remote control is got over
Area's ranging soft pressing plate input, traction institute A, AT institute B and subregion interior range unit will restart automatically, in restarting process, ranging
Device will read this side plant stand of over-zone feeding messaging parameter Zhong Yue areas, more area's offside plant stand number, more this side IP address of area with more
Area's offside IP address, read over-zone feeding protection definite value and over-zone feeding ranging parameters.Automatically after restarting, institute A, AT are drawn
Institute B and subregion institute will form over-zone feeding arm, and these will guarantor between traction institute A, AT institute B and the range unit of subregion institute
Hold communication state.
Special big over-zone feeding state is such as run into, as shown in Figure 4, under normal operating condition, by drawing institute A, AT institute A
Supply arm A is formed with subregion institute 1；Draw institute B, AT institute B and subregion institute 1 forms supply arm B；Draw institute B, AT institute C and subregion institute 2
Form supply arm C.Under over-zone feeding state, by drawing institute A, AT institute C, subregion institute 1 forms over-zone feeding arm.This high-speed railway is led
Draw power supply more area's fault localization technology and still adapt to more area's condition.
The above method can switch range unit to more area's running status by remote auto, reduce range unit and get over area
Adjust required human and material resources and time, and applicability is respectively provided with for various over-zone feeding conditions, substantially increase traction
The reliability of power supply.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, some improvement and deformation can also be made, these are improved and deformation
Also it should be regarded as protection scope of the present invention.
