Description
Technical Field
The invention relates to the technical field of mobile communication power supplies, in particular to an energy-saving power supply method and system.
Background
In recent years, distributed computing of domestic IDC (Internet Data Center), IT and Internet technologies such as rack servers and the like are rapidly developed, and a plurality of new technical applications including inter-column air conditioning, natural cooling, high-voltage direct current, direct mains supply and the like appear in the bottom Data Center. Then, after a plurality of new technologies are integrated, the concept of MDC (data Center micro module) appears, wherein the data Center micro module based on own business is delivered in a large scale by domestic internet companies, and the rapid development of the micro module data Center in China is promoted. Many manufacturers in China also publicize the solution of the micromodule, and most of the manufacturers are stuck with various labels, so that the energy is saved, the first construction cost is reduced, the construction scheme is flexible, and the like.
The micromodule is a data center module which is decomposed by a server/network facility and an infrastructure facility and becomes a common carrier after certain logic precise coupling, and can be an independent complete data center on computing or storage resources. Different mapping convergence ratio logics exist in service conditions and server/network facility conditions of different companies, and the finding of the optimal matching ratio is a key problem, and relates to optimization of a server/network equipment TCO (Total Cost of Ownership) and an IDC data center TCO.
However, in existing data centers, less than half of the power is actually used for the computer loads. And more than half of the electricity charges are used to charge the power consumed by the power supply system, the cooling system and the lighting. The total power consumption can be summarized into two major parts: (1) power consumed by the IT load; (2) power consumed by the device is supported. Only about 30% of the power consumed by a data center is actually used to power IT loads, with the remainder being consumed by power supplies, refrigeration and lighting. IT can be said that the efficiency of this data center is 30% because only 30% of the total input power is used for IT loads. Thus, 70% of the input power does not do any "useful work" to the data center, resulting in inefficient power usage by the data center.
Therefore, how to reduce the power waste of the data center and improve the power utilization efficiency of the power equipment of the data center server cabinet is one of the technical problems to be solved urgently.

Example one
As shown in fig. 1a, a schematic structural diagram of an energy-saving power supply system provided in an embodiment of the present invention includes: the power consumption monitoring system comprises a power consumption acquisition platform 11, an environment monitoring platform 12, a switching power supply plug-in frame unit 13, a storage battery pack 14, at least one energy-saving control unit 15 and at least one micro-module server cabinet 16, wherein the at least one energy-saving control unit 15 is used for controlling the power supply mode of the micro-module server cabinet 16 connected with the at least one energy-saving control unit, and the power consumption monitoring system comprises:
the power consumption collection platform 11 is configured to count, for each micro module server cabinet 16, a conversion efficiency power consumption value of a power supply of the micro module server cabinet 16 and send the power consumption value to the environment monitoring platform 12.
The environment monitoring platform 12 is configured to determine, for each micro module server cabinet 16, a power supply mode of the micro module server cabinet 16 according to the obtained conversion efficiency energy consumption value of the power supply of the micro module server cabinet 16, and send the power supply mode to the energy saving control unit 15 corresponding to the micro module server cabinet 16 through the switching power supply plug-in frame unit 13; or according to the determined power supply mode of the micro module server cabinet 16, controlling the storage battery pack 14 to discharge and supply power to the micro module server cabinet 16.
The at least one energy-saving control unit 15 is configured to, for each micro module server cabinet 16, switch the power supply mode of the micro module server cabinet 16 to the power supply mode determined by the environment monitoring platform 12 according to the power supply mode of the micro module server cabinet 16 determined by the environment monitoring platform 12.
The principle of the energy-saving power supply method provided by the embodiment of the invention is as follows: referring to fig. 1a, for each micro module server cabinet, the power collection platform 11 collects a conversion efficiency energy consumption value of a power supply of each server included in the micro module server cabinet 16, determines a conversion efficiency energy consumption value of the power supply of the micro module server cabinet 16 according to the determined conversion efficiency energy consumption value of the power supply of each server included in the micro module server cabinet 16, and then sends the determined conversion efficiency energy consumption value of the power supply of the micro module server cabinet 16 to the environment monitoring platform 12. After receiving the conversion efficiency energy consumption value of the power supply of the micro module server cabinet 16, the environment monitoring platform 12 compares the conversion efficiency energy consumption value with a pre-stored preset conversion efficiency energy consumption range of the power supply; based on the comparison, the power mode of the micro module server cabinet 16 is determined. After the environment monitoring platform 12 determines the power supply mode of the micro module server cabinet 16, the power supply mode sends the switching power supply plug-in frame unit 13 to the energy saving control unit 15 corresponding to the micro module server cabinet 16, or controls the storage battery pack 14 to discharge and supply power to the micro module server cabinet 16 according to the determined power supply mode of the micro module server cabinet 16. After receiving the power supply mode of the micro module server cabinet 16 connected thereto, which is sent by the switching power supply inserting frame unit 13, the energy saving control unit 15 switches the power supply mode of the micro module server cabinet 16 to the power supply mode determined by the environment monitoring platform 12.
It should be noted that, when counting the conversion efficiency energy consumption value of the power supply of each micro module server cabinet 16, the power consumption collection platform 11 first counts the conversion efficiency energy consumption value of the power supply of each server included in the micro module server cabinet 16, for this reason, the power consumption collection platform 11 needs to number each micro module server cabinet 16 in advance, and number each server included in each micro module server cabinet 16, and based on this, determines which micro module server cabinet 16 the conversion efficiency energy consumption value of the power supply of the server counted by the power consumption collection platform 11 belongs to, so as to determine the conversion efficiency energy consumption value of the power supply of each micro module server cabinet 16, for example, referring to fig. 1a, where there are 4 micro module server cabinets 16 in fig. 1a, the 4 micro module server cabinets 16 are numbered respectively, the 4 micro module server racks 16 may be numbered sequentially from left to right, and the numbers of the 4 micro module server racks 16 are "1", "2", "3", and "4" sequentially from left to right. After 4 micro module server racks 16 are numbered, taking the micro module server rack 16 with the number "1" as an example for explanation, when there are four servers in the micro module server rack 16, the numbers of the four servers may be set to "11", "12", "13" and "14". Similarly, servers contained in other miniature server racks 16 may also have their servers numbered with reference to the method. So far, the power consumption collection platform 11 may determine which micro module server cabinet 16 the server belongs to according to the serial number of the server, so as to obtain the energy consumption value of the conversion efficiency of the power supply of the micro module server cabinet 16. Of course, other methods may also be used to identify the micro module server rack and the servers contained therein, which is not limited in the embodiments of the present invention.
For convenience of description, the embodiment of the present invention is described by taking the micro module server cabinet numbered "1" and 4 servers included in the micro module server cabinet as examples.
In specific implementation, the micro module server rack 16 includes a plurality of servers, and the power collection platform 11 is specifically configured to determine, for each server included in the micro module server rack 16, a Central Processing Unit (CPU) utilization rate and a CPU frequency of the server; determining the conversion efficiency energy consumption value of the power supply of the server according to the obtained CPU utilization rate and CPU frequency of the server; and determining the conversion efficiency energy consumption value of the power supply of the micro module server cabinet 16 according to the determined conversion efficiency energy consumption value of the power supply of each server contained in the micro module server cabinet.
For example, the power consumption collection platform 11 needs to collect the CPU utilization and CPU frequency of 4 servers in the micro module server rack numbered "1".
Determining a conversion efficiency energy consumption value of a power supply of the server according to the obtained CPU utilization rate and CPU frequency of the server;
when determining the conversion efficiency energy consumption value of the power supply of each server, the determination can be performed according to the following method:
(1) the conversion efficiency and power consumption of the power supply of the server need to be determined firstly, and specifically include:
assuming that Q (k, f) is the conversion efficiency power consumption of the power supply of the server, the CPU utilization rate is represented by k, and the CPU frequency is represented by f, then:
the method comprises the following steps: if the CPU frequency is not changed, i.e. f is constant, the relation between Q (k) and k is obtained as follows:
Q(k)＝a*k+P1+γ1(1)
wherein: a represents a CPU utilization coefficient, which is a variable and can be obtained from a server operating system; p1Representing the basic power consumption of the energy-saving power supply system when the CPU is idle, judging whether the CPU is idle according to the preset threshold value according to the application condition of the operating system of the server, if the current power consumption of the server is less than the preset threshold value, judging that the CPU is idle, and if the current power consumption of the server is more than the preset threshold value, judging that the CPU is not idle; gamma ray1Represents a primary correction factor, which may be plus or minus five percent of power consumption.
Step two: if the CPU utilization is not changed, i.e. k is constant, the relation between Q (k) and f can be obtained as follows:
Q(f)＝b*f3+P2+γ2(2)
wherein: b is expressed as a CPU power consumption correction value and is a fixed value; p2Representing the power consumption of the system when the CPU is busy; gamma ray2Represents a quadratic correction factor, which may be plus or minus five percent of the power consumption.
F in the formula (2)3As a whole, viewed as an argument, to simplify the derivation, equation (3) can be derived:
based on equation (3), the conversion efficiency power consumption Q (k, f) of the power supply of each server can be determined as:
Q(k,f3)＝αkf3+βf3+k+λ (4)
wherein: the expression of α, β, λ is:
so far, the conversion efficiency power consumption of the power supply of the server can be determined by using the above formula (4) and formula (5).
(2) Determining an energy consumption value for conversion efficiency of a power supply of a single server
It should be noted that, when determining the conversion efficiency and power consumption of the power supply of the server, in order to simplify the operation, the embodiment of the present invention simplifies the server in the data center into a homogeneous mode, that is: the values of α, β, λ are the same at each node, and then the conversion efficiency energy consumption value of the power supply of the server is determined on the basis thereof.
Step three: determining the conversion efficiency energy consumption value of the power supply of the single server by using a formula (6):
in the formula (6), qi(t) conversion efficiency power consumption of power supply of a single server, since CPU usage rate and CPU frequency of the server vary with time while the server is operatingNamely, the CPU utilization rate and the CPU frequency of the server are both functions of time, so that the functions of the conversion efficiency and the power consumption of the power supply of the server, the CPU utilization rate and the CPU frequency are further converted into functions of time t, and the functions are obtained:
q(t)＝αk(t)f3(t)+βf3(t)+k(t)+λ (7)
after determining the conversion efficiency power consumption value of the power supply of a single server, the conversion efficiency power consumption value of the power supply of the server in the T time period can be deduced, namely:
the conversion efficiency energy consumption value of the power supply of the ith server can be determined by the formula (8), so that the conversion efficiency energy consumption value of the power supply of each server contained in the micro module server cabinet can also be determined by the formula (8).
And secondly, determining the conversion efficiency energy consumption value of the power supply of the miniature module server cabinet 16 according to the determined conversion efficiency energy consumption value of the power supply of each server contained in the miniature module server cabinet.
Based on the conversion efficiency energy consumption value of the power supply of the single server determined in the third step, assuming that a certain micro module server cabinet in the system comprises N servers, the conversion efficiency energy consumption value of the power supply of the micro module server cabinet is as follows:
therefore, the conversion efficiency energy consumption value of the power supply of the micro module server cabinet can be determined according to the conversion efficiency energy consumption value of the power supply of each server contained in the micro module server cabinet.
In addition, after obtaining the conversion efficiency energy consumption value of the power supply of the micro module server cabinet, the conversion efficiency energy efficiency of the power supply of the micro module server cabinet can be further determined, and the CPU utilization rate and the CPU frequency of each server included in the micro module server cabinet are sampled at intervals of Δ T within the T period, so that the formula (9) can be simplified as follows:
the conversion efficiency and energy efficiency of the power supply of the micro module server cabinet in the T time period can be obtained by the formula (10)
The method comprises the following steps that L (T) is an energy consumption value of the miniature module server cabinet, the conversion efficiency and the energy efficiency of a power supply of the miniature module server cabinet in a T time period can be determined by a sampling formula (11), the CPU frequency and the CPU utilization rate of each physical node of the data center can be acquired, the total energy efficiency of the whole data center can be calculated by the sampling method, the independent energy efficiency of each physical node can also be calculated, and the method has the characteristics of low force and simplicity in implementation. In addition, as can be seen from the formula (11), the energy efficiency n (t) is related to f (t), k (t), and the energy consumption value e (t) of the conversion efficiency of the power supply of the micro module server cabinet can be reduced when the CPU frequency is turned down or the CPU is made idle as much as possible, but the energy efficiency n (t) of the conversion efficiency of the power supply of the micro module server cabinet can not be necessarily improved. If the energy efficiency of the conversion efficiency of the power supply of the miniature module server cabinet in the data center is most caused, the energy efficiency value of the conversion efficiency of the power supply of the whole data center can reach the maximum value. For a micro module server cabinet, if the energy efficiency of a single server is maximum at any time T, n (T) in the T period, n (T) is maximum, so equation (11) can be simplified as follows:
first, the relationship between n (t) and k (t) is studied, and the numerator and denominator of formula (12) are divided by k (t) to obtain:
since f (t) is constantly greater than zero, it can be derived from equation (13) that n (t) increases with increasing k (t), i.e., the greater the CPU utilization, the greater the energy efficiency n (t). Since k (t) has a value range of [0,1], energy efficiency n (t) has a maximum value when k (t) is 1.
Then, the relation between n (t) and f (t) is studied, and the derivative of f (t) from equation (12) is obtained:
order to
It can be found that:
as can be seen from equation (16), equation (15) has a maximum value when k (t) is a fixed value, and when k (t) is 1,
when the energy efficiency n (t) is maximum, namely when the CPU of the server in the miniature module server cabinet operates according to the fixed frequency, the conversion efficiency energy efficiency of the power supply of the miniature module server cabinet is maximum. The CPU frequency of the server is controlled through the strategy, the power supply conversion efficiency of the server is improved to achieve the energy-saving purpose, the relevant energy-saving strategy is customized through the application use condition of the tested server, and the set strategy is applied to each tested server, so that the power supply conversion efficiency of the cabinet of the WeChat module server achieves the energy-saving purpose.
In specific implementation, the environment monitoring platform 12 is specifically configured to compare the obtained conversion efficiency energy consumption value of the power supply of the micro module server cabinet 16 with a pre-stored preset range of conversion efficiency energy consumption of the power supply; based on the comparison, the power mode of the micro module server cabinet 16 is determined.
Preferably, the environment monitoring platform 12 may determine the power mode of the micro module server cabinet 16 according to the method shown in fig. 1b, which may include the following steps:
and S111, determining an energy consumption preset range corresponding to the conversion efficiency energy consumption value of the power supply of the miniature module server cabinet.
And S112, determining the power supply mode corresponding to the energy consumption preset range as the power supply mode of the miniature module server cabinet according to the prestored corresponding relation between the energy consumption preset range of the conversion efficiency of the power supply and the power supply mode.
The environment monitoring platform 12 is specifically configured to determine that the power supply mode of the micro module server cabinet 16 is a storage battery maintenance discharge mode if it is determined that the energy consumption preset range corresponding to the conversion efficiency energy consumption value of the power supply of the micro module server cabinet 16 is a first preset range; if the energy consumption preset range corresponding to the conversion efficiency energy consumption value of the power supply of the micro module server cabinet 16 is determined to be a second preset range, determining that the power supply mode of the micro module server cabinet 16 is a direct current power supply mode; if the energy consumption preset range corresponding to the conversion efficiency energy consumption value of the power supply of the micro module server cabinet 16 is determined to be the third preset range, determining that the power supply mode of the micro module server cabinet 16 is the alternating current power supply mode.
The embodiment of the present invention provides the corresponding relationship between the three preset ranges and the power supply modes, which are described in detail below.
The corresponding relation is as follows: and if the energy consumption preset range corresponding to the conversion efficiency energy consumption value of the power supply of the micro module server cabinet 16 is determined to be the first preset range, determining that the power supply mode of the micro module server cabinet 16 is the storage battery maintenance discharge mode.
For example, in the embodiment of the present invention, the first preset range may be 80% to 83% of power consumption, and when the determined conversion efficiency energy consumption value of the power supply of the micro module server cabinet is within the range of 80% to 83% of power consumption of the micro module server cabinet, the environment monitoring platform 12 determines that the power supply mode of the micro module server cabinet is the storage battery pack maintenance discharge mode, so as to implement the storage battery pack periodic discharge maintenance operation.
Preferably, in the storage battery pack discharging mode, the energy-saving control unit connected to the micro module server cabinet needs to automatically reduce the voltage value, so as to ensure that the voltage value is consistent with the minimum voltage value set by the storage battery pack periodic discharging maintenance, and the storage battery pack continues to supply power to the micro module server cabinet after the storage battery pack completes the discharging maintenance.
The corresponding relation is two: if the energy consumption preset range corresponding to the conversion efficiency energy consumption value of the power supply of the micro module server cabinet 16 is determined to be the second preset range, determining that the power supply mode of the micro module server cabinet 16 is the direct current power supply mode.
In specific implementation, the second preset range may be 84% to 88% of power consumption, and when it is determined that the conversion efficiency energy consumption value of the power supply of the micro module server cabinet is within 84% to 88% of the power consumption of the micro module server cabinet, the power conversion efficiency is very low under a low load condition, that is, more power needs to be consumed on the power supply itself, so that to avoid more power resources being wasted on the power supply itself, the power supply mode of the micro module server cabinet needs to be switched to the dc power supply mode.
The corresponding relation is three: if the energy consumption preset range corresponding to the conversion efficiency energy consumption value of the power supply of the micro module server cabinet 16 is determined to be the third preset range, determining that the power supply mode of the micro module server cabinet 16 is the alternating current power supply mode.
Specifically, the third preset range may be 89% to 94% of power consumption, and when it is determined that the conversion efficiency energy consumption value of the power supply of the micro module server cabinet is within 89% to 94% of the power consumption of the micro module server cabinet, at this time, the conversion efficiency energy consumption value of the power supply is increased along with an increase in load, and the server power supply reaches the highest conversion efficiency at 40% to 60% of load, at this time, the power supply mode of the micro module server cabinet needs to be switched to the ac power supply mode, and the server is fully responsible for supplying power.
Preferably, the environment monitoring platform 12 is further configured to count, for each micro module server cabinet 16, a total power consumption of the micro module server cabinet 16, and determine that the power supply mode of the micro module server cabinet 16 is an ac, dc, and storage battery pack hybrid power supply mode if the total power consumption of the micro module server cabinet 16 exceeds a preset value.
In specific implementation, before the environment monitoring platform counts the total power consumption of the micro module server cabinets, in order to identify which micro module server cabinet the counted power consumption corresponds to, the power consumption collection platform may refer to the numbering manner of the micro module server cabinets, number the micro module server cabinets, receive the current value of the micro module server cabinet connected to the energy-saving control unit 15, and forward the current value to the environment monitoring platform 12 through the switching power supply plug-in frame unit 13. Because the micro module server cabinet adopts alternating current-direct current dual-path input, the current collected by the energy-saving control unit 15 can be alternating current or direct current.
When the current collected by the energy-saving control unit 15 is ac, the environment monitoring platform 12 may determine the total power consumption of the micro module server cabinet according to the current value, that is, the current value is 220V; when the current collected by the energy-saving control unit 15 is direct current, the environment monitoring platform 12 may determine the total power consumption of the micro module server cabinet according to the current value, that is: current value is the voltage value adopted by the frame unit of the switching power supply.
In addition, the current value obtained by the environment monitoring platform can also be used for determining the number of the servers contained in the micro module server cabinet, because the current value of the servers is generally constant, such as 6A.
When determining the total power consumption of the micro module server cabinet, the environment monitoring platform 12 compares the total power consumption with a preset value pre-stored in the environment monitoring platform 12, and if determining that the total power consumption exceeds the preset value, determines that the power supply mode of the micro module server cabinet is an alternating current, direct current and storage battery pack hybrid power supply mode.
