[0025] In S202, phase powers corresponding to three current phases of a current distribution unit are determined according to module powers of at least one power module connected to the current distribution unit, wherein the dual-input power supply device includes two current distribution units, and a phase power corresponding to an Nth phase is determined according to module powers of at least one Nth power module, the Nth power module is a power module with an Nth current phase, and N is an integer greater than or equal to 1 and less than or equal to 3.

[0026] Optionally, in the embodiment, the dual-input power supply device can be, but is not limited to, a power supply device with two independent power supply input interfaces, which can access two different current distribution units or power supply loops. The two independent power supply interfaces access different current distribution units, and only one of the inputs provides power when the dual-input power supply device is working normally. The dual-input device can realize N+1 redundant power supply, where N depends on the maximum load of the system, which not only retains line redundancy to improve power supply reliability, but also improves the maximum power supply power of the system under the same number of power sources.

[0028] Optionally, in the embodiment, the current distribution unit (PDU) can be, but is not limited to, a power distribution device for distributing external input power to multiple devices in the cabinet, which can realize monitoring, distribution and overload protection of current. The current distribution unit in the embodiment can be, but is not limited to, a three-phase PDU in a three-phase power supply scenario.

[0029] Optionally, in the embodiment, the power supply module (PSU) can be, but is not limited to, a component that converts input alternating current into direct current required by servers and other devices, and provides stable power supply for the devices. The power supply module in the embodiment supports dual-input power supply and has an input line switching function. It can be understood as, but is not limited to, that the power supply module is connected to two different current distribution units at the same time, but only one of the current distribution units supplies power to the power supply module during power supply, thereby realizing power conversion and stable output, guaranteeing the power demand of servers and other devices, and improving power supply reliability through dual-input redundancy. When one of the inputs fails, the other input can be switched to continue power supply.

[0030] Optionally, in the embodiment, the module power can be, but is not limited to, the rated power that a single power supply module can provide in a normal working state, or the power value output during actual work, which can be used as a basis for calculating phase power and judging three-phase balance state. The module power can be used to calculate the total load of each phase and each power distribution unit.

[0031] Optionally, in the embodiment, the three phases can be, but are not limited to, three different phases in three-phase alternating current, namely, the first phase, the second phase, and the third phase, and there is a 120° electrical angle difference between each phase, which together form a three-phase power supply system and can realize the transmission and distribution of three-phase power.

[0032] Optionally, in the embodiment, the three phases can be, but are not limited to, three-phase alternating current, which is composed of a power supply system of three alternating current electromotive forces with the same frequency, equal amplitude, and a 120° phase difference, corresponding to three independent power supply lines, and together forming a complete three-phase power supply loop.

[0033] In the embodiment, the three-phase balance can be, but is not limited to, a state in which the load power on the first phase, the second phase, and the third phase of the three-phase alternating current power supply system is evenly distributed. In the three-phase balanced state, the power amplitudes of the three phases are equal, the phase difference is kept at 120°, and the deviation of each phase load from the average load is within a preset range.

[0034] Optionally, in the embodiment, the phase power can be, but is not limited to, the sum of the module powers of all power supply modules in a certain current phase corresponding to the current current distribution unit, which can be used to reflect the total load of the current current distribution unit in the phase.

[0035] Optionally, in the embodiment, first, all power supply modules connected to the current current unit are found, and the module power of each module is obtained; then, the power supply modules are classified according to the current phase, and the module powers belonging to the same phase are added to obtain the phase power corresponding to the current current distribution unit in the three phases, respectively.

[0036] S204, according to the deviation degree between the phase power corresponding to each of the three current phases and the first reference phase power, determine the phase deviation degree corresponding to each of the three current phases, wherein the first reference phase power is determined according to the three phase powers;

[0037] Optionally, in the embodiment, the first reference phase power can be, but is not limited to, a reference value calculated according to the phase power of the three current phases, which can be used to measure the difference between each phase power and the average level, which can be, but is not limited to, the average value of the sum of the phase powers corresponding to the three current phases, which can be used as a reference for judging the phase deviation degree. By comparing the deviation degree between each phase power and the first reference phase power, it is determined whether each phase needs to be adjusted.

[0038] Optionally, in the embodiment, the phase deviation degree can be, but is not limited to, a deviation degree between the phase power of a certain phase and the first reference phase power, which can reflect the unbalance degree of the load of the phase, and further determine whether the phases are in a balanced state. If the phase deviation degree is too large, the power supply condition of the power module needs to be adjusted.

[0039] Optionally, in the embodiment, the first reference phase power is calculated according to the three phase powers, and then the difference between the phase power of each phase and the first reference phase power is calculated, which is used to quantify the phase deviation degree of the unbalance degree of each phase, so that the load difference of each phase can be quantified as a specific phase deviation degree value, which is convenient for intuitively determining whether each phase is balanced, and provides a basis for subsequent three-phase balance adjustment.

[0040] S206, in the case that the three phase deviation degrees meet the adjustment condition, at least one target adjustment module is determined from the plurality of power modules included in the dual-input power supply device;

[0041] Optionally, in the embodiment, the adjustment condition can be, but is not limited to, a pre-set judgment standard for determining whether the circuit relationship of the power module needs to be adjusted. If one or more phase deviation degrees exceed the target deviation degree range, the adjustment condition is met, so that the trigger time of the adjustment operation is determined, unnecessary adjustment is avoided, and the three-phase balance state in the dual-input power supply device is ensured to meet the requirements.

[0042] Optionally, in the embodiment, the target adjustment module can be, but is not limited to, a power module selected from all power modules, which needs to adjust the circuit relationship with the current distribution unit, and the circuit relationship of the target adjustment module is adjusted, so as to optimize the load distribution of each phase, reduce the phase deviation degree, and realize the three-phase balance in the dual-input power supply device.

[0043] Optionally, in the embodiment, it is determined whether the three phase deviation degrees meet the pre-set adjustment condition. If the adjustment condition is met, the target adjustment module is selected from all power modules in the cabinet, and the circuit relationship of the target adjustment module is adjusted to realize the three-phase balance adjustment in the dual-input power supply device.

[0044] S208, the circuit relationship between the at least one target adjustment module and the current distribution unit is adjusted.

[0045] Optionally, in the embodiment, the circuit relationship adjustment can be, but is not limited to, changing the power supply relationship between the target adjustment module and the current module, and can be, but is not limited to, adjusting the current distribution unit that supplies power to the power module, so as to change the load distribution of each phase, reduce the phase deviation degree to the target range, realize the three-phase balance of the current distribution unit, and ensure stable power supply.

[0046] Optionally, in the embodiment, by adjusting the circuit relationship between the target adjustment module and the current current distribution unit, the power supply for the target adjustment module by the current current distribution unit is adjusted to be supplied by other current distribution units, or the power supply for the target adjustment module by other current distribution units is adjusted to be supplied by the current current distribution unit, so as to change the load distribution of each phase of the current current distribution unit.

[0047] It should be noted that by adjusting the circuit relationship of the power supply module, the load distribution is optimized, the three-phase load of the current current distribution module tends to be balanced, and without relying on complex hardware wiring adjustment, the dynamic balance can be controlled by switching the current distribution unit for the power supply module, thereby reducing the requirement for wiring technology capability, avoiding the cable confusion problem, ensuring the balance and reliability of the power supply line of the dual-input power supply equipment, and reducing the damage caused by three-phase imbalance.

[0048] Through the embodiment of the application, the module power of each of the at least one power supply module connected to the current current distribution unit is determined, and the phase power of each phase of the three-phase current distribution unit is calculated accordingly. Further, according to the three phase powers, a reference phase power is obtained, which is used to measure the balance state of the current three-phase power supply. Subsequently, according to the deviation degree between each phase power and the reference phase power, the phase deviation degree of each phase is quantitatively evaluated. When it is detected that any phase deviation degree exceeds a preset adjustment threshold, at least one target adjustment module is selected from the plurality of power supply modules included in the dual-input power supply equipment; finally, the circuit relationship between the target adjustment module and the current current distribution unit is adjusted. By switching the circuit relationship between the target adjustment module and the current current distribution unit, three-phase balance adjustment of the dual-input power supply equipment can be realized without the need for re-wiring inside the dual-input power supply equipment, thereby solving the problem of low efficiency of realizing three-phase balance of the dual-input power supply equipment.

[0049] As an optional solution, before determining at least one target adjustment module from the plurality of power supply modules included in the dual-input power supply equipment, it comprises:

[0050] S1-1, obtaining phase total power corresponding to three current phases respectively, wherein the phase total power corresponding to the Nth phase is determined according to the module power of each of the at least one Nth power supply module;

[0051] S1-2, determining the cabinet deviation degree corresponding to the dual-input power supply equipment according to the deviation degree between the phase total power with the largest absolute value in the three phase total powers and the second reference phase power, wherein the second reference phase power is determined according to the three phase total powers;

[0052] S1-3, determine the adjustment conditions based on the rack deviation.

[0053] Optionally, in this embodiment, the total phase power may, but is not limited to, refer to the total load power of each of the three current phases in the dual-input power supply device, and may, but is not limited to, be the sum of the module power of all power modules under the corresponding phase.

[0054] Optionally, in this embodiment, the second reference phase power may be, but is not limited to, a reference value calculated based on the total power of the three phases of the cabinet, which can be used to measure the difference between the total power of each phase at the cabinet level and the ideal balance state. It may be, but is not limited to, the total power obtained by summing the total power of the three phases, and the average power on each phase.

[0055] Optionally, in this embodiment, the cabinet deviation can refer to, but is not limited to, the degree of three-phase imbalance of the dual-input power supply equipment as a whole. It can be calculated based on, but is not limited to, the deviation between the total power of the phase with the largest absolute value among the three phases and the power of the second reference phase. The cabinet deviation can reflect the overall three-phase balance of the cabinet, thereby determining whether it is necessary to start the subsequent power module adjustment process, so that the adjustment operation aims to optimize the overall balance of the cabinet, rather than the local balance.

[0056] Optionally, in this embodiment, the total phase power of a phase is obtained by statistically analyzing the module power of all power modules in each phase and summing them up, thereby completing the collection of global three-phase load data of the cabinet, providing a basis for evaluating the overall balance of the cabinet, and thus avoiding the problem of global imbalance of the cabinet caused by adjustments only targeting local areas.

[0057] Next, the phase with the largest absolute value is selected from the total power of the three phases, and the second reference phase power is calculated. Then, by using the total power of the phase with the largest absolute value and the second reference phase power, the deviation between the maximum phase power and the second reference phase power is calculated to obtain the rack deviation. This quantifies the overall three-phase imbalance state of the rack into a specific value, providing a basis for determining the adjustment conditions.

[0058] Finally, adjustment conditions are determined based on the rack deviation. If the phase deviation of a certain current distribution unit calculated later exceeds the target range set based on the rack deviation, the adjustment conditions are determined to be met, so that the adjustment conditions address both the local imbalance of the current distribution unit and the overall balance target of the rack.

[0059] It should be noted that the adjustment condition is set by the cabinet deviation degree, so as to ensure that the adjustment operation of the local current distribution unit serves the overall balance of the cabinet, prevent the problem that the imbalance of other phases of the cabinet is aggravated to solve the imbalance of a current distribution unit, so that the adjustment of three-phase balance can also meet the overall cabinet three-phase balance of the dual-input power supply equipment in the case of local three-phase balance.

The adjustment condition is set by the cabinet deviation degree, so as to ensure that the adjustment operation of the local current distribution unit serves the overall balance of the cabinet, prevent the problem that the imbalance of other phases of the cabinet is aggravated to solve the imbalance of a current distribution unit, so that the adjustment of three-phase balance can also meet the overall cabinet three-phase balance of the dual-input power supply equipment in the case of local three-phase balance.

[0061] As an optional solution, at least one target adjustment module is determined from the plurality of power modules included in the dual-input power supply equipment, comprising:

[0062] S2-1, the three phase deviation degrees are traversed, and in the case that the current phase deviation degree meets the adjustment condition, the adjustment power matched with the current phase deviation degree is determined based on the current phase deviation degree, the cabinet deviation degree and the three phase total powers, wherein the adjustment power is used to indicate the total power value that needs to be adjusted;

[0063] S2-2, in the case that the current phase deviation degree is positive, at least one first reference power module is determined as at least one target adjustment module, wherein the first reference power module is a power module in the dual-input power supply equipment in power supply relationship with the current current distribution unit, the power phase corresponding to the first reference power module is the same as the power phase corresponding to the current phase deviation degree, the sum of the module powers corresponding to the at least one first reference power module is greater than or equal to the adjustment power, and the circuit relationship includes the power supply relationship;

[0064] S2-3, in the case that the current phase deviation degree is negative, at least one second reference power module is determined as at least one target adjustment module, wherein the second reference power module is a power module in the dual-input power supply equipment in power supply relationship with other current distribution units, the power phase corresponding to the second reference power module is the same as the power phase corresponding to the current phase deviation degree, and the sum of the module powers corresponding to the at least one second reference power module is greater than or equal to the adjustment power.

[0065] Optionally, in the embodiment, the adjustment power can be, but is not limited to, the total power value required to adjust the phase to reach the balanced state when the current phase deviation meets the adjustment condition, so as to determine the power scale that the current phase needs to be adjusted, provide a quantitative standard for the screening target adjustment module, avoid over-adjustment or under-adjustment, and ensure that the phase deviation after adjustment meets the requirements.

[0066] Optionally, in the embodiment, the first reference power supply module can be, but is not limited to, a power supply module in the dual-input power supply device that has a power supply relationship with the current current distribution unit and has the same phase as the phase corresponding to the current phase deviation, and when the current phase deviation is positive, the first reference power supply module can be used as one of the optional target adjustment modules to reduce the power of the current phase by switching it to other current distribution units.

[0067] Optionally, in the embodiment, the second reference power supply module can be, but is not limited to, a power supply module in the dual-input power supply device that has a power supply relationship with other current distribution units and has the same phase as the phase corresponding to the current phase deviation, and when the current phase deviation is negative, the second reference power supply module can be used as one of the optional target adjustment modules to increase the power of the current phase by switching it to the current current distribution unit.

[0068] Optionally, in the embodiment, the power supply relationship can be, but is not limited to, a connection state between the power supply module and the current distribution unit, and can be, but is not limited to, understood as the current distribution unit from which the power supply module obtains power, which is a component of the circuit relationship.

[0069] Optionally, in the embodiment, first, the phase deviation of the current current distribution unit at each of the three phases is checked one by one to determine whether each phase deviation meets the adjustment condition; for the current phase deviation that meets the adjustment condition, the total power value required to adjust the phase is calculated based on the current phase deviation, the cabinet deviation, and the total power of the three phases, and if the current phase deviation is positive, the adjustment power is the power value that needs to be reduced; if it is negative, the adjustment power is the power value that needs to be increased.

[0070] Then, if the current phase deviation is positive, it indicates that the load of the phase is higher than the preset range corresponding to the adjustment condition, and the power needs to be reduced. At this time, the first reference power supply modules are selected from the dual-input power supply device, the first reference power supply modules are sorted in descending order of module power, the least number of modules whose power sum is greater than or equal to the adjustment power is selected as the target adjustment modules, and the power supply relationship of the target adjustment modules is adjusted to reduce the power of the current phase.

[0071] If the current phase deviation degree is negative, it indicates that the phase load is lower than the preset range corresponding to the adjustment condition, the power needs to be increased, at this time, the second reference power modules are selected from the dual-input power supply device, the second reference power modules are sorted in descending order according to the module power, the least number of modules whose power sum is greater than or equal to the adjustment power are selected as the target adjustment modules, and the power supply relationship of the target adjustment modules is adjusted to realize the increase of the current phase power.

[0072] It should be noted that by constructing the phase screening, power quantification and module screening, the target adjustment module is screened according to the phase deviation degree of the current power distribution module, and the first reference power module or the second reference power module is determined as the target adjustment module according to the phase deviation degree and the adjustment power, thereby effectively solving the three-phase imbalance problem of the dual-input power supply using the three-phase current distribution unit, and ensuring the three-phase balance inside the dual-input power supply device.

[0073] According to the embodiments of the present application, three phase deviation degrees are traversed, and in the case that the current phase deviation degree meets the adjustment condition, the adjustment power matched with the current phase deviation degree is determined based on the current phase deviation degree, the cabinet deviation degree and the three-phase total power, wherein the adjustment power is used to indicate the total power value that needs to be adjusted; in the case that the current phase deviation degree is positive, at least one first reference power module is determined as at least one target adjustment module, wherein the first reference power module is a power module in the dual-input power supply device that has a power supply relationship with the current current distribution unit, the power phase corresponding to the first reference power module is the same as the power phase corresponding to the current phase deviation degree, the sum of the module powers corresponding to the at least one first reference power module is greater than or equal to the adjustment power, and the circuit relationship includes the power supply relationship; in the case that the current phase deviation degree is negative, at least one second reference power module is determined as at least one target adjustment module, wherein the second reference power module is a power module in the dual-input power supply device that has a power supply relationship with other current distribution units, the power phase corresponding to the second reference power module is the same as the power phase corresponding to the current phase deviation degree, and the sum of the module powers corresponding to the at least one second reference power module is greater than or equal to the adjustment power.

[0076] S3-2, obtaining power difference between phase reference power and phase average power;

[0077] S3-3, determining cabinet deviation degree according to the ratio of power difference to the sum of three-phase total power.

[0078] Optionally, in the embodiment, the phase reference power can be but is not limited to the three-phase total power with the largest absolute value selected from the three-phase total power, which can be but is not limited to reflecting the most significant phase in the three-phase load of the cabinet. By determining the most unbalanced phase in the three-phase load of the cabinet, the total power of the phase is used as a reference parameter to ensure that the cabinet deviation degree obtained in the subsequent calculation can obtain the main contradiction of the overall imbalance of the cabinet, and avoid evaluation deviation caused by focusing on non-critical phases.

[0079] Optionally, in the embodiment, the three-phase total power of each phase of the dual-input power supply equipment is first collected, and the phase average power of the three-phase total power is calculated. Then, the phase reference power is determined by selecting the three-phase total power with the largest value from the three-phase total power. By determining the evaluation imbalance degree, the reference is determined by the phase average power, and the main phase of the three-phase imbalance of the cabinet is determined by the phase reference power.

[0080] Then, the power difference between the determined phase reference power and the phase average power is obtained, and the cabinet deviation degree is determined based on the ratio between the power difference and the sum of the three-phase total power.

[0081] It should be noted that by calculating the phase average power and the phase reference power based on the three-phase total power, obtaining the power difference between the two, and finally determining the cabinet deviation degree according to the ratio of the power difference to the sum of the three-phase total power, the problem of only focusing on the local balance of a single current distribution unit and ignoring the global balance of the cabinet is effectively avoided, and the accuracy of performing three-phase balance on the dual-input power supply equipment is improved.

[0082] According to the embodiment, the phase average power is obtained based on the three-phase total power, the phase reference power is determined as the phase total power with the largest absolute value among the three-phase total power, the power difference between the phase reference power and the phase average power is obtained, and the cabinet deviation degree is determined according to the ratio of the power difference to the sum of the three-phase total power. The phase average power and the phase reference power are calculated based on the three-phase total power, the power difference between the two is obtained, and finally the cabinet deviation degree is determined according to the ratio of the power difference to the sum of the three-phase total power, which effectively avoids the problem of only focusing on the local balance of a single current distribution unit and ignoring the global balance of the cabinet, and further improves the accuracy of performing three-phase balance on the dual-input power supply equipment.

[0083] As an optional solution, the adjustment condition is determined based on the cabinet deviation degree, and the adjustment condition includes at least one of the following:

[0084] S4-1, obtaining the load change of each server in the dual-input power supply equipment in different time periods, and determining the adjustment condition based on the load change and the cabinet deviation degree;

[0085] S4-2, obtaining the heat change of each server in the dual-input power supply equipment in different time periods, and determining the adjustment condition based on the heat change and the cabinet deviation degree.

[0086] Optionally, in the embodiment, the load change can be but is not limited to the power load fluctuation caused by the change of the operation pressure and the data processing amount of each server in the dual-input power supply equipment in different time periods, and can include but is not limited to the CPU usage rate, memory occupancy rate or actual power consumption change of the server. Further, the load change is illustrated by taking the CPU usage rate as an example. Optionally, for a dual-input power supply equipment, the CPU usage rate of server 1 increases from 30% to 85% during the business peak period from Monday to Friday, and the CPU usage rate of server 2 increases from 25% to 75%. During the off-peak period on Saturday and Sunday, the usage rates of server 1 and server 2 decrease to 10%.

[0087] Optionally, in the embodiment, the heat change can be but is not limited to the heat fluctuation of each server in the dual-input power supply equipment caused by the load change, which is positively correlated with the power consumption of the server. It can be understood that if the heat is too large, it can be explained that the power consumption of the server is also too large, and the three-phase balance needs to be adjusted.

[0088] Optionally, in the embodiment, the load parameters of each server in the cabinet at different time periods are collected in real time by the server management system, the load fluctuation rules of the servers are analyzed and recorded, and the adjustment condition is dynamically set according to the load fluctuation trend in combination with the cabinet deviation degree. In the load peak period, the threshold of the adjustment condition is reduced to ensure timely response to the imbalance caused by sudden load increase. In the load valley period, the threshold is increased to reduce unnecessary adjustment operation.

[0089] Optionally, in the embodiment, the temperature data of the periphery of each server at different time periods is collected by the temperature sensor in the cabinet, the heat change of each server is analyzed in combination with the corresponding relationship between the server power consumption and the heat generation, and the adjustment condition threshold is appropriately reduced in the high heat period to avoid further imbalance of load distribution caused by the decrease of module efficiency. In the low heat period, the threshold is increased to reduce the interference of adjustment on the system.

[0090] It should be noted that by respectively acquiring the load change and the heat change of each server in the dual-input power supply device at different time periods, and dynamically determining the adjustment condition in combination with the cabinet deviation degree, the problems of untimely adjustment in the load peak period or excessive adjustment in the load valley period are avoided, the limitation of only paying attention to the load and ignoring the influence of heat on the efficiency of the power supply module is compensated, and it is ensured that the adjustment condition can match the actual needs of the dual-input power supply device under different running scenarios.

[0091] According to the embodiments of the present application, the load change of each server in the dual-input power supply device at different time periods is acquired, and the adjustment condition is determined based on the load change and the cabinet deviation degree. The heat change of each server in the dual-input power supply device at different time periods is acquired, and the adjustment condition is determined based on the heat change and the cabinet deviation degree. By respectively acquiring the load change and the heat change of each server in the dual-input power supply device at different time periods, and dynamically determining the adjustment condition in combination with the cabinet deviation degree, it is ensured that the adjustment condition can match the actual needs of the dual-input power supply device under different running scenarios.

[0092] As an optional solution, the circuit relationship between the at least one target adjustment module and the current current distribution unit is adjusted, including:

[0093] S5-1, determining at least one third reference power supply module from a plurality of power supply modules included in the dual-input power supply device based on the power supply phase corresponding to the target adjustment module, wherein the power supply phase corresponding to the third reference power supply module is the same as the power supply phase corresponding to the target adjustment module;

[0094] S5-2, determining a determination result for indicating the three-phase balance feasibility of establishing the circuit of the dual-input power supply device based on the module power corresponding to each of the at least one third reference power supply module.

[0095] S5-3, in the case where the determination result indicates that the three-phase balance of the dual-input power supply device circuit can be established, adjusting the circuit relationship between the at least one target adjustment module and the current distribution unit.

[0096] Optionally, in this embodiment, the third reference power supply module can be, but is not limited to, a power supply module in the dual-input power supply device that has the same power supply phase as the target adjustment module, which can be, but is not limited to, understood as follows: after matching the power supply phase with the power supply phase of the target adjustment module, the power supply module that matches successfully is determined as the third reference power supply module.

[0097] Optionally, in this embodiment, the determination result can be, but is not limited to, a conclusion based on the module power of the third reference power supply module, that is, whether the three-phase balance of the dual-input power supply device circuit can be achieved by adjusting the circuit relationship of the target adjustment module, which can be used as a basis for whether to perform the circuit relationship adjustment, so as to avoid forcibly adjusting in the case where the balance target cannot be achieved, reduce the influence of invalid operations on the stability of power supply, and at the same time ensure that the adjustment operation targets the achievable three-phase balance, thereby improving the adjustment efficiency.

[0098] Optionally, in this embodiment, the power supply phase of the target adjustment module is determined, and all power supply modules in the dual-input power supply device are traversed to filter out modules that are consistent with the power supply phase, for example, assuming that the target adjustment module is phase A, all phase A power supply modules can be used as the third reference power supply module. Then, based on the module power corresponding to each of the third reference modules, a determination result for indicating the feasibility of establishing the three-phase balance of the dual-input power supply device is determined. Then, based on the determination result, the at least one target adjustment module is adjusted.

[0099] It should be noted that by determining the third reference power supply module of the same phase based on the power supply phase of the target adjustment module, and then combining the module power of the third reference power supply module to determine the feasibility of three-phase balance, the circuit relationship between the target adjustment module and the current distribution unit is finally adjusted when it is determined that the three-phase balance can be established, which avoids invalid operations or power supply risks caused by blind adjustment, and also ensures that the adjustment operation always targets the global three-phase balance of the cabinet, thereby ensuring the balance and stability of the power supply of the dual-input power supply device.

[0100] According to the embodiments of the present application, based on the power phase corresponding to the target adjustment module, at least one third reference power module is determined from the plurality of power modules included in the dual-input power supply device, wherein the power phase corresponding to the third reference power module is the same as the power phase corresponding to the target adjustment module; based on the module power corresponding to each of the at least one third reference power module, a determination result for indicating the feasibility of establishing three-phase balance of the dual-input power supply device circuit is determined; and in the case that the determination result indicates that the three-phase balance of the dual-input power supply device circuit can be established, the circuit relationship between the at least one target adjustment module and the current distribution unit is adjusted.

[0101] As an optional solution, based on the module power corresponding to each of the at least one third reference power module, the determination result for indicating the feasibility of establishing three-phase balance of the dual-input power supply device circuit is determined, comprising:

[0102] S6-1, at least one first target module is determined from the at least one third reference module based on the circuit relationship between the at least one third reference module and the current distribution unit, wherein the first target module has a power supply relationship with the current distribution unit, and the circuit relationship includes the power supply relationship;

[0103] S6-2, the power modules in the at least one third reference module that are not the first target module are determined as at least second target modules;

[0104] S6-3, the module power corresponding to each of all the first target modules is summed to obtain a first total power;

[0105] S6-4, the module power corresponding to each of all the second target modules is summed to obtain a second total power;

[0106] S6-5, the total power difference between the first total power and the second total power is obtained;

[0107] S6-6, based on the module power corresponding to each of the at least one first target module and the module power corresponding to each of the at least one second target module, a power absolute value set is determined, wherein the power absolute value set includes the absolute value of the difference between the module power corresponding to any one of the first target modules and the module power corresponding to any one of the second target modules;

[0108] S6-7, in the case that the total power difference is less than the minimum value in the power absolute value set, the determination result is determined as the failure of establishing three-phase balance of the dual-input power supply device circuit.

[0109] Optionally, in the embodiment, the first target module can be, but is not limited to, a power module that has a power supply relationship with the current current distribution unit and is screened out from the third reference module. The second target module can be, but is not limited to, the remaining part of the third reference module after excluding the first target module, and can be, but is not limited to, understood as a same-phase power module that has a power supply relationship with other current distribution units.

[0110] Optionally, in the embodiment, the first total power can be, but is not limited to, the sum of the module powers of all first target modules. The second total power can be, but is not limited to, the sum of the module powers of all second target modules.

[0111] Optionally, in the embodiment, the power absolute value set can be, but is not limited to, a set composed of absolute values of differences between the module power of any one first target module and the module power of any one second target module, and can be, but is not limited to, used to reflect the difference of the smallest power adjustment unit between the two types of modules.

[0112] Optionally, in the embodiment, first, the circuit relationship between the third reference module and the current PDU is determined, and whether it is powered by the current current distribution unit is determined by reading the state word of the module; the state word is displayed as a power module powered by the current current distribution unit, which is screened out and determined as the first target module. Within the scope of the third reference module, the part that has been determined as the first target module is excluded, and the remaining modules that have a power supply relationship with other current distribution units are determined as the second target module.

[0113] Then, all first target modules are traversed, the real-time module power of each module is collected, these power values are accumulated, and the sum obtained is the first total power, which is used to represent the actual load size of the corresponding phase of the current current distribution unit. All second target modules are traversed, the real-time module power of each module is collected, these power values are accumulated, and the sum obtained is the second total power, which is used to represent the actual load size of the corresponding phase of other current distribution units. The absolute value difference between the first total power and the second total power is calculated to obtain the total power difference, and the load difference value of the corresponding phase of the current current distribution unit and other current distribution units is obtained.

[0114] Finally, the power difference absolute value set of the first target module and the second target module is established, that is, the power of each first target module is calculated with the power of each second target module, and the absolute value is taken. After removing the duplicates of all results, an absolute value set is formed, and the minimum value is extracted from the set. If the minimum value extracted from the set is greater than the total power difference, it is determined that three-phase balance cannot be established.

[0115] It should be noted that by separating the first target module and the second target module from the third reference module, the first total power and the second total power of the two types of modules are calculated respectively, the total power difference is obtained, the absolute value set of the power of the two types of modules is constructed, and the minimum value is extracted, and finally it is determined that the three-phase balance cannot be established when the total power difference is less than the minimum value, which effectively avoids the power supply fluctuation caused by forced operation when there is no adjustment space or insufficient adjustment precision, and ensures the stable operation of the dual-input power supply equipment power supply system.

[0116] According to the embodiment of the present application, at least one first target module is determined from at least one third reference module based on the circuit relationship between the at least one third reference module and the current distribution unit, wherein the first target module has a power supply relationship with the current distribution unit, and the circuit relationship includes the power supply relationship; the power supply modules in the at least one third reference module that are not the first target module are determined as at least second target modules; the module powers corresponding to all first target modules are summed to obtain a first total power; the module powers corresponding to all second target modules are summed to obtain a second total power; a total power difference between the first total power and the second total power is obtained; based on the module powers corresponding to the at least one first target module and the module powers corresponding to the at least one second target module, a power absolute value set is determined, wherein the power absolute value set includes the absolute value of the difference between the module power corresponding to any one first target module and the module power corresponding to any one second target module; in the case that the total power difference is less than the minimum value in the power absolute value set, the determination result is determined as a failure to establish three-phase balance of the dual-input power supply equipment circuit. By separating the first target module and the second target module from the third reference module, the first total power and the second total power of the two types of modules are calculated respectively, the total power difference is obtained, the absolute value set of the power of the two types of modules is constructed, and the minimum value is extracted, and finally it is determined that the three-phase balance cannot be established when the total power difference is less than the minimum value, which effectively avoids the power supply fluctuation caused by forced operation when there is no adjustment space or insufficient adjustment precision, and ensures the stable operation of the dual-input power supply equipment power supply system.

[0117] As an optional solution, at least one target adjustment module is determined from the plurality of power supply modules included in the dual-input power supply equipment, comprising:

[0118] S7-1, based on the three phase deviation degrees, a sorted list is obtained, and the first phase deviation degree in the sorted list is determined as the target phase deviation degree, wherein the sorted list is determined based on the absolute values of the three phase deviation degrees;

[0119] S7-2, in the case that the target phase deviation degree meets the adjustment condition, at least one target adjustment module is determined from the plurality of power supply modules included in the dual-input power supply equipment;

[0120] S7-3, in the case where the target phase deviation degree does not satisfy the adjustment condition, determining the next phase deviation degree in the sorting list as the target phase deviation degree.

[0121] Optionally, in the embodiment, the sorting list can be, but is not limited to, a list formed by sorting the three phase deviation degrees in descending order of their absolute values, and the sorting is based on the absolute values of the deviation degrees to highlight the phase with the most serious imbalance. By explicitly prioritizing the imbalance of each phase, the most serious phase is prioritized for processing, avoiding the key problem from being unsolved due to unordered adjustment, and improving the efficiency of balance adjustment.

[0122] For further illustration, assuming that the absolute values of the three phase deviation degrees are 6.67%, 0.2%, and 6.67% respectively, the sorting list is [6.67%, 6.67%, 0.2%] after sorting in descending order of absolute values.

[0123] Optionally, in the embodiment, the target phase deviation degree can be, but is not limited to, the phase deviation degree selected from the sorting list and currently to be evaluated for adjustment, and the initial target phase deviation degree is the first element in the list, which can be understood as the phase deviation degree with the largest absolute value. If the adjustment condition is not satisfied, the next element is selected. By explicitly focusing on the current phase, it is determined whether to start the module adjustment process of the phase by evaluating whether the adjustment condition is satisfied, ensuring that the adjustment operation focuses on the phase that needs to be improved the most.

[0124] Optionally, in the embodiment, the phase deviation degrees of the three phases of the cabinet in the dual-input power supply device are first obtained, and the absolute values of the deviation degrees are extracted. Then, the three phase deviation degrees are sorted in descending order of absolute values to form a sorting list. Finally, the first element in the list, such as the phase deviation degree with the largest absolute value, is determined as the initial target phase deviation degree, thereby determining the phase that needs to be adjusted the most at present.

[0125] Next, the target phase deviation degree is compared with the adjustment condition. If the condition is satisfied, the corresponding power module is selected according to the type of the target phase: if the load of the target phase is too high, the power module powered by the current current distribution unit in the phase is selected as the target adjustment module; if the load is too low, the power module connected with other current distribution units in the phase is selected as the target adjustment module.

[0126] If the target phase deviation degree does not satisfy the adjustment condition, the next phase deviation degree in the sorting list is taken as the new target phase deviation degree, and the evaluation process is performed again. If all phase deviation degrees do not satisfy the condition, it is determined that balance adjustment is not needed.

[0127] It should be noted that by generating a ranking list based on the absolute values of the three phase deviation degrees and sequentially determining the target phase deviation degree, the target adjustment module is screened when the target phase deviation degree meets the adjustment condition, and the next phase deviation degree is polled when it does not meet the condition, which realizes the priority processing of the most serious phase imbalance problem in the three-phase balance adjustment of the dual-input power supply, avoids missing other potential adjustment requirements, improves the pertinence and efficiency of the three-phase balance adjustment, and further ensures the balance and stable operation of the dual-input power supply equipment power supply system.

[0128] According to the embodiment of the present application, a ranking list is obtained based on the three phase deviation degrees, and the first phase deviation degree in the ranking list is determined as the target phase deviation degree, wherein the ranking list is determined based on the absolute values of the three phase deviation degrees; at least one target adjustment module is determined from the plurality of power modules included in the dual-input power supply equipment when the target phase deviation degree meets the adjustment condition; the next phase deviation degree in the ranking list is determined as the target phase deviation degree when the target phase deviation degree does not meet the adjustment condition. By generating a ranking list based on the absolute values of the three phase deviation degrees and sequentially determining the target phase deviation degree, the target adjustment module is screened when the target phase deviation degree meets the adjustment condition, and the next phase deviation degree is polled when it does not meet the condition, which realizes the priority processing of the most serious phase imbalance problem in the three-phase balance adjustment of the dual-input power supply, avoids missing other potential adjustment requirements, improves the pertinence and efficiency of the three-phase balance adjustment, and further ensures the balance and stable operation of the dual-input power supply equipment power supply system.

[0129] As an optional solution, the phase deviation degrees corresponding to the three current phases respectively are determined according to the deviation degrees between the phase powers corresponding to the three current phases respectively and the first reference phase power, including:

[0130] S8-1, summing the three phase powers to obtain a phase power sum;

[0131] S8-2, obtaining a first difference value between the phase power corresponding to the first phase and the reference phase power;

[0132] S8-3, determining the phase deviation degree corresponding to the first phase based on the ratio of the first difference value to the phase power sum;

[0133] S8-4, obtaining a second difference value between the phase power corresponding to the second phase and the reference phase power;

[0134] S8-5, determining the phase deviation degree corresponding to the second phase based on the ratio of the second difference value to the phase power sum;

[0135] S8-6, obtaining a third difference value between the phase power corresponding to the third phase and the reference phase power;

[0136] S8-7, determining the phase deviation degree corresponding to the third phase based on the ratio of the third difference value to the phase power sum.

[0137] Optionally, in the embodiment, the real-time phase powers of the three phases of the dual-input power supply device are collected, the sum of the three phase powers is obtained through addition operation, and the sum is determined as the phase power sum, so as to reflect the current total power supply load scale of the cabinet.

[0138] Then, the phase power of the first phase among the three phases is selected, the reference phase power is subtracted from the phase power, to obtain a first difference value, the positive and negative of the first difference value reflect the load level, and the first difference value is divided by the phase power sum, so as to obtain the first phase deviation degree; the phase power of the second phase among the three phases is selected, the reference phase power is subtracted from the phase power, to obtain a second difference value, and the second difference value is divided by the phase power sum, so as to obtain the second phase deviation degree; the phase power of the third phase among the three phases is selected, the reference phase power is subtracted from the phase power, to obtain a third difference value, and the third difference value is divided by the phase power sum, so as to obtain the first phase deviation degree.

[0139] It should be noted that the phase power sum is obtained by summing the three phase powers, the difference value between each phase and the reference phase power is calculated, and the ratio of the difference value to the phase power sum is determined as the phase deviation degree of each phase, so as to comprehensively and quantitatively evaluate the three-phase load imbalance degree of the dual-input power supply device, and provide a numerical basis for subsequent three-phase balance adjustment.

[0140] According to the embodiment of the present application, the three phase powers are summed to obtain the phase power sum; the first difference value between the phase power corresponding to the first phase and the reference phase power is obtained; the phase deviation degree corresponding to the first phase is determined based on the ratio of the first difference value to the phase power sum; the second difference value between the phase power corresponding to the second phase and the reference phase power is obtained; the phase deviation degree corresponding to the second phase is determined based on the ratio of the second difference value to the phase power sum; the third difference value between the phase power corresponding to the third phase and the reference phase power is obtained; and the phase deviation degree corresponding to the third phase is determined based on the ratio of the third difference value to the phase power sum. The phase power sum is obtained by summing the three phase powers, the difference value between each phase and the reference phase power is calculated, and the ratio of the difference value to the phase power sum is determined as the phase deviation degree of each phase, so as to comprehensively and quantitatively evaluate the three-phase load imbalance degree of the dual-input power supply device, and provide a numerical basis for subsequent three-phase balance adjustment.

[0141] As an optional solution, in order to better understand the process of the above-mentioned three-phase balance method of the dual-input power supply device, the flow of the three-phase balance method of the dual-input power supply device will be described in combination with the optional embodiment below, but it is not used to limit the technical solutions of the embodiments of the present application.

[0142] First, add a control machine, a current sensor, and a voltage sensor in the cabinet. The control machine can be a remote control machine or one of the servers in the cabinet. The current sensor can obtain the input current of each phase of the input three-phase power, and the voltage sensor can obtain the voltage of each phase of the three-phase power. The data information obtained by the current sensor and the voltage sensor can be directly transmitted to the control machine; when the control machine is a remote control machine, the data information can be transmitted to the control machine through the management switch. The control machine can communicate with the server through the management switch and can issue instructions to control each power module to switch the input.

[0143] Next, add a working state flag bit of the power module, denoted as T, and represent the working state of the power module on the server as two bytes. The PDU state word indicates that the working state is in the PDU at a certain position 1, and the phase state word indicates that the working state is in a certain phase at a certain position 1, and the other positions are default values 0. In this way, the state of each power module can be represented as the following six kinds, which is represented by a 16 hexadecimal number as T=0x11 or 0x12 or 0x14 or 0x21 or 0x22 or 0x24. At the same time, the power of each power supply is denoted as P1…Pm, and m is the total number of power supplies. Then, the i-th power module is represented by its working state flag character Ti and power Pi. Since the PSU can switch the input, the PSU can switch the input from PDU1 or PDU2, that is, the high state of the PSU can be converted, 0x11 and 0x21 can be converted to each other, 0x12 and 0x22 can be converted to each other, and 0x14 and 0x24 can be converted to each other. The low state (phase) cannot be switched, which is due to the fact that when the cabinet is installed, the connection mode between the input cable of each server and the PDU is fixed.

[0144] Then, the power on the PDU and each phase is counted through the working state flag bit. The power value on the PDU or the PDU phase can be determined by counting the sum of the power values of the corresponding state bits. For example, the total power on the A phase of PDU1 in working is calculated by summing all the power of the state bit 0x11, which is denoted as P11, and similarly P11, P12, P14, P21, P22, and P24 can be calculated. The total power on all A phases can be summed by summing all the power with low bit 1 (0x11&0x21), which is denoted as Pa, and similarly Pb and Pc can be calculated. The total power on PDU1 can be summed by summing all the power with high bit 1 (0x11&0x12&0x14), which is denoted as P1, and the total power on PDU2 is denoted as P2.

[0145] Among them, the formula for calculating the A-phase imbalance of PDU1 is shown in formula (1):

[0146] (1);

[0147] The B-phase unbalance degree formula of the PDU1 is shown as formula (2):

[0148] (2);

[0149] The C-phase unbalance degree formula of the PDU1 is shown as formula (3):

[0150] (3);

[0151] The A-phase unbalance degree formula of the PDU2 is shown as formula (4):

[0152] (4);

[0153] The B-phase unbalance degree formula of the PDU2 is shown as formula (5):

[0154] (5);

[0155] The C-phase unbalance degree formula of the PDU2 is shown as formula (6):

[0156] (6).

[0157] The control switches the working input line of the PDU1, monitors each voltage and current value of the PDU1 and the PDU2, and determines the working state flag of the PDU1 corresponding to the working state flag of the PDU1 through the decrease of the power value of a phase and the increase of the power value of another phase. The flow is shown as Figure 3

[0171] Optionally, in the embodiment, as shown in Figure 4 , it is an optional connection mode of the PSU and the DPU, there are servers 402, 404 and 406 in the server cabinet, there are power supply modules 408, 410 and 412 in the server 402, there are power supply modules 414, 416 and 418 in the server 404, and there are power supply modules 420, 422 and 424 in the server 406; the power supply modules 408, 410 and 412 in the server 402 are connected with the A-phase of the current distribution unit 426 and the A-phase of the current distribution unit 428; the power supply modules 414, 416 and 418 in the server 404 are connected with the B-phase of the current distribution unit 426 and the B-phase of the current distribution unit 428; the power supply modules 420, 422 and 424 in the server 406 are connected with the C-phase of the current distribution unit 426 and the C-phase of the current distribution unit 428.

[0172] For example, in this way, the PSU working state flag bit of a server can be 0x11 or 0x21. Under this input cable connection mode, the power supply power statistical value at a moment is P1, P2, Pa, Pb, Pc, P11, P12, P14, P21, P22, P24, and the three-phase imbalance rate 、 、 、 、 At this moment, the most ideal imbalance rate should be the three-phase imbalance rate of the whole cabinet calculated by Pa, Pb and Pc, which is shown in formula (7):

[0173] (7)

[0174] The target of adjusting three-phase unbalance rate should be in a certain range of the above values, for example, the control target is or can be set by the user or dynamically associated and adjusted according to the total load of the system. When a certain phase of a certain PDU deviates from the target value, if > 0, it indicates that the A-phase load of PDU1 is higher than the three-phase average value, and the phase current needs to be reduced, that is, the power supply in state 0x11 is switched to 0x21; if it is less than 0, it indicates that the A-phase load of PDU1 is lower than the three-phase average value, and the phase current needs to be increased, that is, the power supply in state 0x21 is switched to 0x11.

[0175] Optionally, the adjusted power total value in working state 11 is , the power values of the power supply modules in the current working state 11 are recorded as P1, P2, P3,..., Pn, and the power is sorted as P1>P2>P3>...>Pn, and the working state 11 is switched to 21 according to the power size for adjustment until the adjusted power value is greater than Ps, that is, P1+P2+…+Pm>Ps, m≤n. That is, the power corresponding to P1, P2,..., Pm needs to be switched from working state 11 to 21.

[0176] Optionally, the judgment of 0x11 and 0x21 adjustment is that the absolute value of the difference between the two-phase power is less than the minimum value of the difference between the power of any two-phase PSU. For example > If P11-P12 is less than the minimum value of the absolute value of the difference between the power of any power supply in state 0x11 and the power of any power supply in state 0x21. For example: the power of the power supply in state 0x11 is 1000W, 1000W, 200W, and the power of the power supply in state 0x21 is 700W, 700W, 700W, P11-P12=100W, and the minimum value of the absolute value of the difference between the power of any power supply in state 0x11 and the power of any power supply in state 0x21 is 1000W-700W=300W, at this time, it indicates that the A-phase current cannot be more balanced by switching the working state of the power supply.

[0177] After sorting, the two groups of PSUs with the largest deviation from the target value can quickly adjust the unbalanced phase on the PDU to a balanced state, so that each PDU can achieve the best condition of the current state in any period of time, and the power supply balance and reliability on the line. The absolute value of the unbalance degree is sorted, and the one with the largest deviation from the target value is adjusted first, and the working state 11 and the working state 21 are optimally balanced; when the working state 11 and the working state 21 are balanced, the maximum value will change to, and the working state 12 and the working state 22 are adjusted to achieve optimal balance. If the phase with the maximum unbalance rate cannot be further optimized, try to adjust the phase with the minimum unbalance rate, until all the unbalance degrees on the phases meet the requirements.

[0180] S504, obtaining the power Pi of the power supply module i;

[0181] S506, obtaining the voltage and current on PDU1 and PDU2;
