Embodiment
Describe in detail based on accompanying drawing and be used for implementing mode of the present invention.In addition, be used for explanation all figure for the mode that carries out an invention, to the additional same title of the key element with same function, symbol, omitting its explanation repeatedly.
An example of the present invention shown in Fig. 1 is related is used for carrying out the major part of information technoloy equipment and the system of the control that cooperates of storage battery.Wiring represents the system of power supply.Electric power is to be provided from generating by source power supply CPWR10.Voltage register VLTLOG 20 is set in the position of the voltage that can measure source power supply.Recording voltage when voltage register 20 can occur by time sequence or event, according to magnitude of voltage can measure surge (swell), fall, wink stops etc., in addition can also measure power failure.Be connected with uninterrupted power supply(ups) UPS 30 on source power supply 10.Commercial mode when normal, online interaction mode are arranged in UPS 30, the variety of way such as inverter mode when normal, but be not particularly limited.Inverter mode when this record is normal.UPS 30 comprises: rectifier; The transducer CNV31 of conversion from AC to DC; Accumulator array BAT 32; Control the storage battery control part CHGCTL 33 of accumulator array; The inverter INV 34 of conversion from DC to AC; The control part UCTL35 of UPS.In the control part 35 of UPS, the surplus with storage battery monitors, network is corresponding, to the shutdown indication of information technoloy equipment, according to the functions such as charging control of common or rapidly charge mode.Connect the power connection PDU 40 with electric exploration mechanism on UPS 30.Power connection PDU 40 with electric exploration mechanism can measure current value and magnitudes of voltage by enough each sockets (consent), has by network to connect switching on and off that Long-distance Control electric power monitoring, power supply provide.Connect each information technoloy equipment 50 on PDU 40.As an example, be made as server S VR1 (51), SVR2 (52), router RTR53, but also can connect modulator-demodulator, fire compartment wall, interchanger, memory.The built-in control part CTL 55 that information technoloy equipment is cooperated with storage battery control of the present invention in server S VR1 (51).
The network structure at a plurality of strong points that comprises the system of embodiments of the invention 1 shown in Fig. 2.Wiring represents the signal of network.The information technoloy equipment of Fig. 1 with the cooperation control system of storage battery (Sys1) by WAN (Wide Area Network: local area network (LAN)) be connected with other system (Sys2, Sys3).In system (Sys1), router (RTR) 53 is connected the WAN of outside with the LAN (Local AreaNetwork) 60 of inside, a plurality of servers (SVR1, SVR2), UPS 30, be connected to router (RTR) 53 with the power connection (PDU) 40 of electric exploration mechanism, form LAN 60.The information exchange of UPS, PDU, router, voltage register (VLTLOG), humiture register (TMPLOG) is crossed LAN60 and can be communicated with server (SVR1, SVR2).This means that server can carry out with LAN supervision and the control of the internal state of miscellaneous equipment.For example list, if the voltage register is voltage, if Temperature Humidity Sensor is temperature, humidity, the storage battery surplus of UPS, the terminal voltage of storage battery, to the pattern of UPS set, the low electric power control of the information technoloy equipments such as power value with each information technoloy equipment in the power connection of electric exploration function, server, router etc.
Speciality technology of the present invention is to carry out the control that cooperates of information technoloy equipment and storage battery according to the characteristic (time, frequency, interval etc.) of the power failure that dopes.Therefore, at first, list the example that has a power failure to have which kind of effect, effectiveness by prediction.The also double explanation of carrying out the action case of information technoloy equipment and storage battery.The duration of off interval and frequency, power failure is arranged as the characteristic that has a power failure, describe in order.
Illustrate by the prediction off interval and make it possible to carry out the situation that charging interval of accumulator array arranges.The example that arranges based on charging interval of the prediction of off interval shown in Fig. 3.When (t1-t2 constantly) used storage battery operation information technoloy equipment in power failure, storage battery discharged, and at moment t2, battery capacity is almost nil.In the situation that do not predict, owing to not knowing then when can have a power failure, therefore need to charge rapidly in order to next time power failure, at moment t3, charging is completed.On the other hand, in the situation that predict, know that to begin be to be arranged before t4 has a power failure constantly the sufficient time due to next time power failure, as long as therefore carry out the charging of low speed.In the situation that without prediction, owing to carrying out superfluous charging rapidly, irrational the dwindling of life-span that particularly causes excide battery.In addition, in power failure next time, after moment t5 finishes to have a power failure, if in the situation that do not predict that carrying out low speed charges, and causes undercharge in the situation that moment t6 occurs to have a power failure, at moment t7, exhaustion of the accumulators, the service of information technoloy equipment can't continue.In the situation that predict, can complete the charging of battery by charging rapidly before moment t6.Like this, by the prediction off interval, the arrangement of time that can charge, the undercharge that can avoid useless charging rapidly, cause because of the low speed charging.
The effect of the duration of prediction power failure then, is shown.In IT service, be desirably in the power failure process also continuous service, performance is high as far as possible, and still, high meaning of performance consumes a large amount of storage batterys, considers that the capacity of storage battery exhausts, so between performance and battery capacity, balance arranged.Therefore, how the prediction that is shown the duration by power failure of the present invention improves performance.By prediction interruption duration, time that can the estimated service life storage battery, the arrangement of time that therefore can discharge.In the situation that do not predict, consider to adopt following method: due to the duration of not knowing to have a power failure, therefore even in advance the use amount of battery is restricted to and makes less that interruption duration is long also can tackle, although perhaps the use amount of battery is large, can't tackle when interruption duration is long.Shown in Fig. 4, at the example of the large situation of the use amount restriction of battery, the use amount of battery shown in Fig. 5 limits the example of little situation.In Fig. 4, have a power failure between moment t1-t2.In the situation that there is no the prediction of interruption duration, because the use amount restriction of battery is large, therefore, although the IT service can continue in the power failure process, performance suppresses to be prf1.In the situation that carry out the prediction of interruption duration, due to the service time of knowing in advance battery, judge and performance can be increased to prf2 in therefore the storage battery surplus being also included within.This is because owing to grasping interruption duration, therefore can cut down the enough and to spare of the surplus of storage battery.In Fig. 5, have a power failure between moment t3-t5.In the situation that there is no the prediction of interruption duration, although performance is high to prf4, the use amount of battery is many, so the moment t4 in the power failure process, and battery exhausts.Therefore, between moment t4-t5, the electric power of information technoloy equipment is zero, has to end the IT service.For being the result of not expecting with the server that operated to prerequisite in 24 hours.In the situation that carry out the prediction of interruption duration, due to the service time of knowing in advance battery, although therefore performance suppresses can continue the use of storage battery for prf3 in interruption duration.Like this, by the prediction interruption duration, the arrangement of time of the discharge of battery can be carried out, the performance of information technoloy equipment can be improved.
New effect when duration that prediction has a power failure and interval further are shown.It is the example when occuring one time in one day of having a power failure in Fig. 4, Fig. 5.When occuring repeatedly to have a power failure in one day, on the basis of setting up plan how to use battery, importantly interruption duration and these both sides' of off interval prediction.Can repeatedly set up the plan about how using battery, when charging.Example when occuring repeatedly to have a power failure shown in Fig. 6.Twice power failure occured.In the situation that do not predict, in the power failure for the first time of moment t6-t7, although performance is restricted to prf7, battery capacity is reduced to C1 from C3, can continue the IT service.In the power failure for the second time of moment t8-t10, if be similarly prf7 with performance limitations for the first time, cause the running down of battery at moment t9, can't continue IT service.In the situation that prediction interruption duration and off interval, according to the kind of battery, two kinds of methods are arranged, therefore describe respectively.The first is to estimate that the total total ascent time that repeatedly has a power failure and the storage battery use amount of determining each time power failure make it possible to the method for the IT service of lasting this time.It is the method for the lead accumulator of spended time in being suitable for charging.Another kind is to estimate each time interruption duration and off interval and charge rapidly to recover battery capacity in outage to be the method that service continues and performance improves that prerequisite realizes IT.It is the method for deteriorated few lithium ion battery of life-span under being suitable for charging rapidly.In first method, by being prf6 with performance limitations, can both use storage battery in twice power failure, service can continue.Battery capacity is being reduced to C2 from C3 in having a power failure for the first time, in having a power failure next time from the C2 vanishing.In the second approach, on the basis that performance is made as higher than the prf7 of prf6, by charge rapidly to recover battery capacity between having a power failure, can take into account continuing and high performance of service.Constantly be in power failure in t6-t7, so battery capacity is reduced to C1 from C3, but implemented charging rapidly before the moment t8 that next time has a power failure, making capacity resuming is C3, in order to the power failure from moment t8.
Like this, the duration that has a power failure by prediction and have a power failure with have a power failure between the interval and estimate, can carry out the arrangement of time of the optimum that discharges and recharges of battery, accompany therewith, have advantages of that the service that can realize information technoloy equipment continues and the performance raising.Given this, in embodiments of the invention 1, the example of the project of prediction in having a power failure shown in Fig. 7.Management unit is made as one day, but is not particularly limited.At this, table is divided into summary and details.As summary, list the having or not of power failure, the frequency of power cut of a day, the longest interruption duration, total total ascent time of power failure, the shortest and maximum duration of off interval.As the data of details, list time started of power failure and concluding time to represent when have a power failure in 24 hours.Can be also to have by each minute the method that has or not that table is put down in writing power failure.About off interval, need to cross over management unit (a day) and calculate.Dope March 1,9:00-12:00,16:00-18:00,20:00-21:00 have a power failure, and frequency of power cut is 3 times, and the longest interruption duration is 3 hours, and the total time that has a power failure is 6 hours, and off interval is minimum is 2 hours, and the longest is 13 hours.The maximum duration of off interval is 21 till 10 o'clock of March 2 13 hours on March 1.
In addition, estimate that the characteristic (time, frequency, interval etc.) that has a power failure changes according to place or week etc.
About the prediction that has a power failure, because being estimates, therefore prediction sometimes can depart from.Prediction departs from the situation that time of having a power failure, having a power failure or interval are the length different from reality that do not occur.Reply method when therefore, the record prediction departs from this patent.Controlling with cooperating of storage battery based on the information technoloy equipment of the prediction that has a power failure is be used to the feedfoward control of avoiding battery allowance to use up.When prediction departs from, switch to the FEEDBACK CONTROL that judges according to battery allowance.Its example shown in Figure 8.For the ease of observing figure, with between performance prf1 and prf2, compress between battery capacity C1 and C2 and put down in writing.Be following situation: the estimation of interruption duration is moment t1-t2, but actual specific t1-t2 is long, and power failure has occured t1-t5 in the moment.In the situation that longer than the time that dopes, feed back based on the actual measurement of battery allowance.In the situation that not for the countermeasure of time lengthening, cause the running down of battery at moment t3, can't move information technoloy equipment during moment t3-t5.Therefore, when surpassing the time of the plan dope, strictly carry out the performance limitations of information technoloy equipment based on the actual measurement of the power value of the surplus of battery and information technoloy equipment.Also tail off along with surplus and improve gradually frequency the opportunity of actual measurement.The interval of t2-t3, t3-t4, t4-t5 shortens successively constantly.Like this, feed back to by the measured value with the surplus of battery the method that performance limitations makes the capacity that has battery in outage, be made as the reply in the situation that prediction departs from.
By more than, show the control example that the reply when departing from is predicted in the action of advantage that prediction has a power failure, information technoloy equipment and storage battery, the cooperate example controlled and power failure.In view of the action case that cooperates and control of information technoloy equipment and storage battery, the detailed construction of information technoloy equipment and the control part that cooperates of storage battery is described then.
The structure of the control part CTL 55 of the control that information technoloy equipment is cooperated with storage battery of the first embodiment of the present invention shown in Fig. 9.Control part CTL 55 moves in server S VR.Control part 55 both can consist of with hardware such as microcomputers, also can be made of software.Comprise: power failure prediction section POE (Power Outages Estimation) 70, it has the interface with voltage monitor, and the time that prediction has a power failure and frequency are also set up the plan that has a power failure, the actual current power failure information that whether is in power failure of expression; The IT power budget IPB of section (IT Power consumption Budget) 80, it has the interface with UPS 30, determines the electrical power limit value of information technoloy equipment based on the storage battery surplus of the interruption duration that dopes and UPS; IT electric power control part IPC (IT low-Power Control) 90, the interface that it has with power connection PDU 40 hangs down the electrical power limit value that electric power controls to satisfy determined information technoloy equipment.The action summary of control part CTL55 is as follows.Predict the time, the interval that have a power failure, determine the electrical power limit value of information technoloy equipment based on battery allowance, make information technoloy equipment to move in the interruption duration that estimates.Then, the low electric power that carries out information technoloy equipment is controlled and is made the electrical power limit value that converges to determined information technoloy equipment.
The structure of each functional module then, is described.The structure of the prediction section of power failure shown in Figure 10 POE 70.The generation that the measured value output expression of power failure prediction section POE use voltage register 20 has a power failure and end, the current actual power failure information that whether is in power failure, with the voltage data of data extraction unit storage voltage register, the voltage data of storing is carried out statistical analysis set up the power failure plan.The date and time data of obtaining with the voltage data of 71 couples of voltage register VLTLOG 20 of data extraction unit, from OS are carried out format, the extraction of data.Both can by the time sequential extraction procedures, also can extract according to the event of variation in voltage.To being kept in data store 72 with the time series form after the additional date and time of the data of extracting with data extraction unit 71.In statistical analysis section 73, the time series data of data storage part 72 is carried out statistical analysis, generate time series models.Rolling average (MA), autoregression model (AR), ARMA model (ARMA), broad sense autoregressive conditional different Variance model (GARCH) etc. are arranged in time series models, but be not defined.In statistical analysis section 73, with the Data Update time series models of every day.For time series data, the prediction that also can be used as Sunday is got simply weekly the average grade on Sunday and is carried out general statistical disposition.In addition, also can learn to improve precision by ensemble machine.In power failure calculating part 74, the power failure plan of the information at the timing of setting with timer, the frequency that for example 0:00 sets up the power failure that dopes the same day, time, interval is also preserved planning data, and notice is to IT power budget section 80.
The structure of the IT power budget IPB of section 80 of the first embodiment of the present invention shown in Figure 11.In IT power budget section 80, has following function: determine IT electrical power limit value as the restriction power value of information technoloy equipment based on the storage battery surplus of the power failure plan of power failure prediction section 70 and UPS30, based on the interval determination charge mode of the power failure that goes out by the power failure plan forecast.From UPS 30 with the specification 81 of the surplus of storage battery and voltage, the power failure plan from power failure prediction section POE 70, actual power failure information and accumulator array as input, in battery application plan section 82, based on determining that battery charging plan that battery at which time band charges with which kind of pattern and battery allowance and the power failure scheduled time calculate IT electrical power limit value.According to battery charging plan, charge mode is notified to UPS 30.Regularly or aperiodically measure the storage battery surplus of UPS 30 with timer when having a power failure, calculate IT electrical power limit value based on duration and its storage battery surplus of the power failure shown in power failure in the works at every turn.
Calculate the method for IT electrical power limit value in this explanation.What for continuous service information technoloy equipment in the interruption duration that is estimated by power failure prediction section POE 70, need to determine to the mobile electric current of information technoloy equipment 50 based on battery allowance and the terminal voltage of UPS 30.For this reason, need to calculate based on the flash-over characteristic of storage battery.One example of the flash-over characteristic of storage battery shown in Figure 12.In order to simplify, use the storage battery of a 12V.Suitably parallel connectionization, series connectionization are considered to get final product in accumulator array.When rated capacity was made as C, the discharge time of storage battery, the size according to discharging current CA changed.Under 1CA 40 minutes, but be 20 hours under 0.05CA.Therefore, determine that in the scope that satisfies the interruption duration that estimates discharging current gets final product.This becomes IT electrical power limit value.For example in order to have the interruption duration of 2 hours, as long as discharging current is set as below 0.25CA.
Then, the structure of the electric power of IT shown in Figure 13 control part IPC90.The electric power data of each information technoloy equipment that IT electric power control part IPC90 gets with the power connection PDU 40 that uses with electric exploration, the IT electrical power limit value that calculates with the IT power budget IPB of section 80 are carried out the low electric power of each information technoloy equipment and are controlled as input.
The action case of electric power control of information technoloy equipment being hanged down for the IT electrical power limit value in outage shown in Figure 14.Hang down electric power and control the IT electrical power limit value that calculates based on storage battery surplus and power failure predicted time to satisfy.Measure termly battery allowance and reexamine IT electrical power limit value, use up with the surplus of avoiding battery in remaining power failure predicted time.Set IT electrical power limit value with the mensuration power value of reality.
