Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that specific embodiment described herein is only used to explain the present invention, not
For limiting the present invention.
Since the type of information technoloy equipment is more, the operating load between equipment and equipment is also not quite similar, and therefore, successively replaces
The degree of balance of load when the mode of restocking equipment does not ensure that actual motion.Such as: three equipment of N batch restocking, this three
The operating load of platform equipment successively decreases, by restocking respectively to the first rack, the second rack and third rack；N+1 batch restocking three
The operating load of platform equipment, three equipment successively decreases, still by restocking respectively to the first rack, the second rack and third rack；
So result is exactly: although seeming this six equipment is mean allocation to three racks, the actually operation of third rack
Load will be substantially less that the first rack.Obviously, this method of salary distribution is extremely unreasonable.If calculating can be passed through before restocking equipment
Or the operating load of equipment opposite can then improve equipment restocking to the smallest rack of operating load in more each rack
Three-phrase burden balance degree.
Based on above-mentioned thinking, the deployed with devices method provided by the present invention based on degree of balance control, as shown in Figure 1, institute
State method comprising steps of
S100, three-phase current is obtained, three-phase current is respectively the first phase current, the second phase current and third phase current.
S200, carry out the first phase current, the size of the second phase current and third phase current compares, will wherein the smallest phase electricity
The corresponding rack of stream is used as to restocking rack.
The prior art and the concept that three-phrase burden balance degree is not present, the present invention is defined it at this as follows: three
Phase load tends to consistent quantitative expression, for measuring the degree of three-phase equilibrium.
Due to UPS (Uninterruptible Power System, i.e. uninterruptible power supply) output voltage be stablize it is constant
, and information technoloy equipment input power module carries PFC (Power Factor Correction, PFC) function, power
Factor is close to 1；Therefore, in the case where UPS load balancing, even if all the way using UPS power supply, all the way using mains-supplied, it is whole
A IT power supply-distribution system load is also balanced, so being with UPS load power, load current or rate of load condensate the expression degree of balance
Valence.It is the most convenient to obtain in view of three-phase current, and therefore, the present invention degree of being balanced will hereafter be calculated by taking three-phase current as an example,
And the foundation as deployed with devices is compared using the size of three-phase current.
Why the present invention associates restocking equipment with three-phrase burden balance degree, is because undercarriage equipment is uncontrollable
, it is needed depending on business, the operating status and administrative provisions of equipment itself, can not determine and the equipment one of undercarriage is needed to be scheduled on pair
Increase in that advantageous phase equipment of the degree of balance, so undercarriage equipment can not be as the means for adjusting balancing the load degree；Only
Equipment to restocking could be as unique succinct and effective means of adjustment degree.(restocking when including change when restocking
Link) it is to increase load, newly-increased load is increased to the adjustable degree of balance in the smallest phase of load always.
As the preferred embodiment of the present invention, the S200 is specifically included:
Judge the first phase current whether less than the second phase current；
If then continuing to judge whether the first phase current is less than third phase current；When judging the first phase current less than the second phase
When electric current, it is meant that the operating load of information technoloy equipment in rack corresponding to the second phase current is greater than rack corresponding to the first phase current
Therefore the operating load of upper information technoloy equipment in next restocking information technoloy equipment, can't consider rack corresponding to the second phase current,
This multilevel iudge will no longer pay close attention to the second phase current.
If then using rack corresponding to the first phase current as to restocking rack.When the first phase current is both less than the second phase
Electric current, and when being less than third phase current, illustrate the operating load minimum of information technoloy equipment in rack corresponding to the first phase current, on next time
The equipment of frame, can be by restocking thereon.
Based on same reason, when the first phase current is greater than third phase current, third phase current is both less than two phase electricity
Stream, and less than the first phase current, illustrate that the operating load of information technoloy equipment in rack corresponding to third phase current is minimum, next restocking
Equipment, can be by restocking thereon.
It is preferred that it is described judge the step of whether the first phase current is less than the second phase current after further include:
If otherwise judging whether the second phase current is less than third phase current；
If then using rack corresponding to the second phase current as to restocking rack, if otherwise will be corresponding to third phase current
Rack be used as to restocking rack.
It is easily understood that the present invention only needs finally judge which phase current is minimum, three mutually electric
The comparative sequence of stream will not influence the solution of the present invention realization, therefore, if first compare the first phase current and the second phase current
Not within the scope of restriction of the invention, other comparative sequences such as first compare the second phase current and third phase current,
Lesser one among the two is compared with the first phase current again；And first by the first phase current and third phase current into
Row comparison, then lesser one among the two is compared with the second phase current, protection model of the invention all should belong to
It encloses.
In addition, it should be noted that in addition to the conditions already mentioned, there are still the following situations: 1, two phases in three phase currents
The value of electric current is equal and is less than another phase current, at this point, two equal phase currents are all minimum phase current, the two institute
Corresponding rack all can be used as to restocking rack, can be all open by two racks when carrying out equipment restocking, can also appoint and select
One opening is used for restocking equipment；2, three phase currents are all equal, at this point, three phase currents are all minimum phase current, three
Corresponding rack all can be used as to restocking rack, can be all open by three racks when carrying out equipment restocking, can also appoint
One or two is selected to open for restocking equipment.It will thus be appreciated that for realizing same when even three-phase current is equal in two-phase
Protection scope of the present invention also should belong in the algorithm application of the multiple racks of Shi Kaifang (or any rack), because that can apply algorithm
More, the present invention no longer repeats this one by one.
Above method step disclosed in this invention is generally managed in the capacity (resource) of data center's monitoring management system
It is called automatically on a node (such as restocking preemption) in process, is the preposition algorithm application of rack position intelligent Matching in equipment,
Its result is by the constraint condition as rack position intelligence Optimum Matching in equipment, for guaranteeing that data center's three-phase power load is flat
Weighing apparatus, and then capacity utilization is improved, the wasting of resources is avoided, part-loading goods are reduced.
According to another aspect of the present invention, before the step of S100 further include: preset for degree of balance early warning
Degree of balance threshold value；After the step of degree of balance threshold value preset for degree of balance early warning further include: calculate in real time
Three-phrase burden balance degree, and degree of balance early warning is issued when the three-phrase burden balance degree is less than degree of balance threshold value.
The calculation formula of the three-phrase burden balance degree are as follows: Lb=1-Max [Max (Idb, Idc), Ida]/2IA, wherein LbFor
Three-phrase burden balance degree, the IAFor three-phase current average value, the IdaFor the inclined of the first phase current and three-phase current average value
Difference, the IdbFor the deviation of the second phase current and three-phase current average value, the IdcIt is average for third phase current and three-phase current
The deviation of value.
If the first phase current is Ia, the second phase current is Ib, third phase current is Ic:
Then: IA=(Ia+Ib+Ic)/3；
Ida=| Ia-IA|；
Idb=| Ib-IA|；
Idc=| Ic-IA|；
Three-phase load unbalance degree Lub=Max [Max (Idb, Idc), Ida]/2IA。
Why the present invention carries out three-phrase burden balance degree calculating, first is that because degree of balance data can verify that above equipment portion
The validity of arranging method；Second is that because the degree of balance is one of the data that data center needs to monitor；Third is that because degree of balance data
Can complex equilibrium degree threshold value, the data exception to be monitored provides judgment basis.
In addition, it is also noted that being outside one's consideration except can use three-phase current calculating three-phrase burden balance, UPS can also be utilized
The power and load factor of output carry out three-phrase burden balance degree.
In addition, three-phrase burden balance degree calculation of the present invention is without paying close attention to whether voltage balances, it is only necessary to pay close attention to load
Whether balance, compared with traditional degree of unbalancedness calculation, the degree of balance in the present invention can be expressed with the mode of percentage, and
Traditional degree of unbalancedness when 1 phase is zero, in addition two-phase either what be worth, degree of unbalancedness all will be indicated as 1 even 2, such as
300,0,0 (degree of unbalancedness 2) and 150,150,0 (degree of unbalancedness 1), it is readable poor, with scheme provided by the present invention
