Abstract
The control method of load is pressed in a kind of EMUs, it is characterised in that：When specifying that pressure is loaded with startup demand in any one, startup request need to be sent, after middle pressure bus is set up, the startup whether real-time judge currently has middle pressure load is asked；The all middle pressure load on bus will be pressed in EMUs according to significance level divided rank.Remarkable result of the invention：Press load to be actuated for management by centering, it is to avoid peak value overlap, while ensure that important load first starts, it is unessential after the principle that starts, it is ensured that the stabilization of vehicle operation；The present invention carries out reasonable distribution by centering pressure load, when off-capacity is aided in, load is pressed in load relieving portion, both ensures that auxiliary capacity can make full use of, while preventing from aiding in overload failure.
Description
Technical field
The invention belongs to railway transport field, and in particular to press the control method of load in a kind of EMUs.
Background technology
In recent years, the development of high-speed railway is maked rapid progress, and EMUs have become people as the people carrier of high-speed railway
The first-selection gone on a journey.And auxiliary power supply system is the important system of EMUs, carry as high pressure traction element provides cooling, be
The load of the passenger such as guest room air-conditioning system, kitchen, electric water boiler comfortableness provides the functions such as power supply.Once auxiliary power supply system occurs
Failure, will cause vehicle late and passenger complains, therefore how ensure that EMUs safely and reliably run, and rationally ensure passenger
The comfortableness of seating becomes each enterprise and strives solving and improved major issue.
The Managed Solution of existing middle pressure load presses bus to set multiple contactors in being mainly vehicle, and middle pressure bus is by connecing
The load supplying on bus section, busbar section that tentaculum disjunction is responsible for into multiple paragraphs, every AuCT to oneself, once certain auxiliary
Current transformer failure, by pressing bus contactor in train network system control closing section, is taken over by adjacent AuCT.Should
Scheme needs train to set substantial amounts of medium voltage contactor, and management and load distribution are extremely complex, easily break down.
The content of the invention
Press load control method in a kind of new EMUs present invention is primarily intended to provide, it is ensured that AuCT safety
Steady operation, and at utmost maintain car operation.
For achieving the above object, the control method of load is provided in a kind of EMUs of present invention offer, it is characterised in that
Comprise the following steps：
When the 1st, specifying that pressure is loaded with startup demand in any one, startup request need to be sent, after middle pressure bus is set up, real-time judge
Whether the current startup for having middle pressure load is asked；
2nd, will press all middle pressure load on bus according to significance level divided rank in EMUs, be loaded with when there is any middle pressure
Start in the presence of request, the grade for first judging the load is N；
3rd, determine whether that also request starts at the same time for the middle pressure load higher than grade N；If it has, being then not responding to grade N loads
Startup request, it is preferential to start grade middle pressure load high；
If the 4, the grade is that the load of N is current highest ranking, the starting current size loaded according to grade N sets it and opens
Dynamic time nS, grade N is allowed to load startup in nS.
5th, in the nS for pressing load startup in grade N, other all middle pressure loads are forbidden to start, no matter other load importants
Whether grade is higher than N, prevents peak value from overlapping and causes vehicle trouble；
6th, after nS, grade N load start completions determine whether that middle pressure is loaded with starting request again.
7th, for the quantity and capacity of the AuCT worked on middle pressure bus, to pressing load to be controlled in full row,
It is preferential to ensure operation according to capacity situation when the demand of load is pressed during the AuCT capacity of work can not meet permutation
Related load normal work, is loaded, it is ensured that AuCT normal work by stop section air-conditioning, electric water boiler.
Advantages and positive effects of the present invention：
（1）The present invention presses load to be actuated for management by centering, it is to avoid peak value overlap, while the important load of guarantee is first opened
It is dynamic, the unessential rear principle for starting, it is ensured that the stabilization of vehicle operation；
（2）The present invention carries out reasonable distribution by centering pressure load, when off-capacity is aided in, load is pressed in load relieving portion, both
Ensure that auxiliary capacity can make full use of, while preventing auxiliary overload failure.
Brief description of the drawings
Fig. 1 starts scheme schematic diagram to press Mo-Co catalyst in the present invention；
Fig. 2 is pressure load control method schematic diagram in the present invention.
Specific embodiment
Refering to Fig. 1, it is as follows that middle pressure load starts control method：
1）Whether each load on middle pressure bus judges itself need to open according to actual conditions such as current environmental temperature, car speeds
It is dynamic, then send startup request if necessary to start.When pressure is loaded with starting request in any one, Mo-Co catalyst is pressed in
Start control flow；
2）According to the significance level of middle pressure load, the load of middle pressure bus is divided into 1-X grades, once there is middle pressure to be loaded with startup please
Ask, the important level for first determining whether the load is N；
3）Judge that grade N is supported on current significance level, if be current all load middle grade highests for thering is startup to ask
's；
4）If grade N is not current highest ranking, the startup feelings for being temporarily not responding to grade N loads are asked, and are preferentially started
Important level load higher；
5）If the load that the request that grade N is current highest ranking starts, according to the starting current size that grade N is loaded,
Its startup time is set for nS, the load of N grades is discharged in nS, it is allowed to its startup；
6）In the start-up course of grade N loads, in order to avoid starting peak value superposition, forbid the entrance of other all middle pressure loads
Sequence starting flow, no matter its grade just, until grade N load startup finish；
7）After nS, grade N loads complete to start, and press sequence starting flow in discharging again, detection it is current whether startup in need
Middle pressure load exist.
Refering to Fig. 2, many AuCTs of EMUs all load supplyings on middle pressure bus in parallel, by meter in real time
AuCT quantity and load capacity are calculated, the control method of current middle pressure load is judged；
1）When currently having 3 and the work of above AuCT, auxiliary capacity disclosure satisfy that loading demand, it is allowed to which all middle pressures are negative
Carry work；
2）When current only 2 AuCTs work, part air-conditioning 1,2 is forced to enter semi-load mode of operation, stop section car
Electric water boiler；
3）When current only 1 AuCT works, the cooling of unnecessary trailer system is cut off, air-conditioning system only retains logical
Wind, all electric water boilers and kitchen are wholly off, it is ensured that vehicle can carry out low cruise.
