[0002] In related technologies, achieving three-phase balance in dual-input power supply equipment, especially in server racks with dual-input power supplies, is often accomplished by switching the phases of the power modules in the servers within the rack. However, the wiring between the power modules and the phases is fixed. If phase switching is required, the dual-input power supply equipment needs to be rewired, which takes a long time. This results in a long time required to achieve three-phase balance within the dual-input power supply equipment, leading to low efficiency in achieving three-phase balance in dual-input power supply equipment.

[0024] This embodiment provides a three-phase balancing method for a dual-input power supply device. Figure 2 This is a flowchart of a three-phase balancing method for a dual-input power supply device according to an embodiment of this application, such as... Figure 2 As shown, the process includes the following steps:

[0025] S202, based on the module power of each of the at least one power module connected to the current current distribution unit in the dual-input power supply device, determine the phase power corresponding to the three current phases of the current distribution unit respectively. The dual-input power supply device has two current distribution units, and the phase power corresponding to the Nth phase is determined based on the module power of each of the at least one Nth power module. The Nth power module is the power module whose current phase is the Nth phase, and N is an integer greater than or equal to 1 and less than or equal to 3.

[0026] Optionally, in this embodiment, the dual-input power supply device may be, but is not limited to, a power supply device with two independent power input interfaces, which can be connected to two different current distribution units or power supply circuits. The two independent power input interfaces are connected to different current distribution units, and when the dual-input power supply device is operating normally, only one input is supplied with power. The dual-input device can achieve N+1 redundant power supply, where N depends on the maximum system load, thus preserving line redundancy to improve power supply reliability and increasing the maximum power supply of the system with the same number of power sources.

[0027] Optionally, in this embodiment, the dual-input power supply device may be, but is not limited to, a server rack for accommodating components such as servers, power modules, and network devices, which can provide physical protection, heat dissipation management, cable management, and unified power supply support for internal devices, and may be, but is not limited to, infrastructure for storing IT equipment in scenarios such as data centers and computer rooms.

[0028] Optionally, in this embodiment, the Power Distribution Unit (PDU) may be, but is not limited to, a power distribution device for distributing externally input electrical energy to multiple devices in a cabinet, which can monitor, distribute, and overload protect the current. In this embodiment, the power distribution unit may be, but is not limited to, a three-phase PDU in a three-phase power supply scenario.

[0029] Optionally, in this embodiment, the power supply unit (PSU) may be, but is not limited to, a component that converts the input AC power into the DC power required by devices such as servers and provides a stable power supply to the devices. In this embodiment, the power supply module supports dual input power and has an input line switching function. This can be understood as the power supply module being connected to two different current distribution units simultaneously, but during power supply, only one current distribution unit supplies power to the power supply module, thereby achieving power conversion and stable output, ensuring the power needs of devices such as servers, and improving power supply reliability through dual input redundancy. If one input fails, the system can switch to the other input to continue supplying power.

[0030] Optionally, in this embodiment, the module power may refer to, but is not limited to, the rated power that a single power module can provide under normal working conditions, or the power value output during actual operation. It can be used as a basis for calculating phase power and judging the three-phase balance state. The total load of each phase and each power distribution unit can be statistically analyzed through the module power.

[0031] Optionally, in this embodiment, the current phase may refer to, but is not limited to, three different phases in the three-phase alternating current, namely the first phase, the second phase, and the third phase. There is a 120° electrical angle difference between each phase, which together constitute a three-phase power supply system, enabling the transmission and distribution of three-phase electrical energy.

[0032] Optionally, in this embodiment, three-phase may refer to, but is not limited to, three-phase alternating current, which is a power supply system composed of three alternating electromotive forces with the same frequency, equal amplitude, and phase difference of 120° electrical angle, corresponding to three independent power supply lines, together forming a complete three-phase power supply circuit.

[0033] In this embodiment, three-phase balance can refer to, but is not limited to, a state in which the load power on the three lines of the first phase, the second phase, and the third phase is evenly distributed in a three-phase AC power supply system. In the state of three-phase balance, the power amplitude of the three phases is equal, the phase difference is maintained at 120°, and the deviation of the load of each phase from the average load of the three phases is within a preset range.

[0034] Optionally, in this embodiment, phase power may refer to, but is not limited to, the sum of the module power of all power modules on a certain current phase corresponding to the current current distribution unit, and can be used to reflect the total load of the current current distribution unit on that phase.

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

[0036] S204, based on the deviation between the phase power corresponding to the three current phases and the first reference phase power, determine the phase deviation of the current distribution unit in the three current phases respectively, wherein the first reference phase power is determined based on the three phase powers;

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

[0038] Optionally, in this embodiment, the phase deviation can refer to, but is not limited to, the degree of deviation between the phase power of a certain phase and the first reference phase power, which can reflect the degree of imbalance of the load of that phase, and thus determine whether each phase is in a balanced state. If the phase deviation is too large, the power supply status of the power module needs to be adjusted.

[0039] Optionally, in this embodiment, the first reference phase power is first calculated based on the three phase powers, and then the difference between the phase power of each phase and the first reference phase power is calculated to quantify the phase deviation of the unbalance of each phase. This allows the load difference of each phase to be quantified into a specific phase deviation value, making it easier to intuitively judge whether each phase is balanced and providing a basis for subsequent three-phase balance adjustment.

[0040] S206, if the three phase deviations meet the adjustment conditions, at least one target adjustment module is determined from the multiple power modules included in the dual-input power supply device;

[0041] Optionally, in this embodiment, the adjustment conditions may be, but are not limited to, pre-set judgment criteria used to determine whether the circuit relationship of the power module needs to be adjusted. If one or more phase deviations exceed the target deviation range, the adjustment conditions are met, thereby clarifying the triggering time of the adjustment operation, avoiding unnecessary adjustments, and ensuring that the three-phase balance state in the dual-input power supply device meets the requirements.

[0042] Optionally, in this embodiment, the target adjustment module may be, but is not limited to, a power module selected from all power modules that requires adjustment of its circuit relationship with the current current distribution unit. By adjusting the circuit relationship of the target adjustment module, the load distribution of each phase is optimized, the phase deviation is reduced, and the three-phase balance inside the dual-input power supply device is achieved.

[0043] Optionally, in this embodiment, it is determined whether the three phase deviations meet the preset adjustment conditions. If the adjustment conditions are met, a target adjustment module is selected from all power modules in the cabinet, and the three-phase balance adjustment in the dual-input power supply device is achieved by adjusting the circuit relationship of the target adjustment module.

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

[0045] Optionally, in this embodiment, circuit relationship adjustment may refer to, but is not limited to, changing the power supply relationship between the target adjustment module and the current current module. It may be understood as adjusting the current distribution unit that supplies power to the power module, thereby changing the load distribution of each phase, reducing the phase deviation to the target range, achieving three-phase balance of the current distribution unit, and ensuring stable power supply.

[0046] Optionally, in this embodiment, by adjusting the circuit relationship between the target adjustment module and the current current distribution unit, the power supply to the target adjustment module is changed from the current current distribution unit to other current distribution units; or, the power supply to the target adjustment module is changed from other current distribution units to the current current distribution unit, thereby changing the load distribution of each phase of the current current distribution unit.

[0047] It should be noted that by adjusting the circuit relationships of the power supply module and optimizing the load distribution, the three-phase load of the current distribution module is made more balanced without relying on complex hardware wiring adjustments. Dynamic balance can be achieved by switching the current distribution unit powered by the power supply module, reducing the requirements for wiring skills and avoiding cable tangles. This ensures the balance and reliability of the power supply lines for dual-input power supply equipment and reduces damage caused by three-phase imbalance.

[0048] In this embodiment, the module power corresponding to each of at least one power module connected to the current current distribution unit is determined, and the phase power of each phase in the three phases of the current distribution unit is calculated accordingly. Further, a reference phase power is derived based on these three phase powers, which is used to measure the balance of the current three-phase power supply. Subsequently, the phase deviation of each phase is quantitatively evaluated based on the degree of deviation between each phase power and the reference phase power. When any phase deviation exceeds a preset adjustment threshold, at least one target adjustment module is selected from the multiple power modules included in the dual-input power supply device; 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 device can be performed without rewiring the internal components, thereby solving the problem of low efficiency in achieving three-phase balance in dual-input power supply devices.

[0049] As an alternative approach, before identifying at least one target adjustment module from among the multiple power modules included in the dual-input power supply device, the following steps are included:

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

[0051] S1-2, Based on 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, determine the cabinet deviation degree corresponding to the dual-input power supply equipment, wherein the second reference phase power is determined based on the total power of the three phases;

[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 by setting adjustment conditions through cabinet deviation, the adjustment operation of local current distribution units is ensured to serve the overall balance of the cabinet. This prevents the problem of exacerbating the imbalance of other phases in the cabinet in order to solve the imbalance of a certain current distribution unit. As a result, the adjustment of three-phase balance can meet the overall three-phase balance of the dual-input power supply equipment while ensuring the local three-phase balance.

[0060] Through the embodiments of this application, the total phase power corresponding to each of the three current phases is obtained, wherein the total phase power corresponding to the Nth phase is determined based on the module power of at least one Nth power module; the cabinet deviation degree corresponding to the dual-input power supply device is determined based on the deviation between the total phase power with the largest absolute value among the three phase total power and the second reference phase power, wherein the second reference phase power is determined based on the total power of the three phases; adjustment conditions are determined based on the cabinet deviation degree. By setting adjustment conditions based on the cabinet deviation degree, it is ensured that the adjustment operation of the local current distribution unit serves the overall cabinet balance, thereby enabling the three-phase balance adjustment to meet the overall cabinet three-phase balance of the dual-input power supply device while achieving local three-phase balance.

[0061] As an alternative, at least one target adjustment module is identified from a plurality of power modules included in a dual-input power supply device, including:

[0062] S2-1, iterate through the three phase deviations, and if the current phase deviation meets the adjustment conditions, determine the adjustment power that matches the current phase deviation based on the current phase deviation, the cabinet deviation, and the total power of the three phases. The adjustment power is used to indicate the total power value that needs to be adjusted.

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

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

[0065] Optionally, in this embodiment, the adjustment power may be, but is not limited to, the total power required to bring the phase to a balanced state when the current phase deviation meets the adjustment conditions. This clarifies the power scale that the current phase needs to be adjusted, provides a quantitative standard for screening target adjustment modules, avoids over-adjustment or under-adjustment, and ensures that the phase deviation meets the requirements after adjustment.

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

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

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

[0069] Optionally, in this embodiment, the phase deviation of the current distribution unit in each of the three phases is checked one by one to determine whether the phase deviation meets the adjustment conditions. For the current phase deviation that meets the adjustment conditions, the total power value that needs to be adjusted for the phase is calculated by combining the current phase deviation, the cabinet deviation, and the total power of the three phases. 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] Next, if the current phase deviation is positive, it indicates that the load on that 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 module is selected from the dual-input power supply device. These first reference power modules are sorted from largest to smallest according to their module power. The fewest number of modules whose sum of power is greater than or equal to the adjustment power are selected and identified as the target adjustment module. The power supply relationship of the target adjustment module is then adjusted to reduce the power of the current phase.

[0071] If the current phase deviation is negative, it indicates that the load on that phase is below the preset range corresponding to the adjustment condition, and the power needs to be increased. At this time, a second reference power module is selected from the dual-input power supply device. These second reference power modules are sorted from largest to smallest power. The fewest number of modules whose sum of power is greater than or equal to the adjustment power are selected as the target adjustment modules. The power supply relationship of the target adjustment modules is then adjusted to increase the power of the current phase.

[0072] It should be noted that by constructing phase screening, power quantization, and module screening, the target adjustment module is selected based on the phase deviation of the current power distribution module. The first or second reference power module is determined as the target adjustment module based on the phase deviation and the adjustment power. This effectively solves the three-phase imbalance problem when using a three-phase current distribution unit with a dual-input power supply, thereby ensuring the three-phase balance inside the dual-input power supply device.

[0073] In this embodiment, three phase deviations are traversed, and when the current phase deviation meets the adjustment conditions, an adjustment power matching the current phase deviation is determined based on the current phase deviation, the cabinet deviation, and the total power of the three phases. The adjustment power indicates the total power value to be adjusted. When the current phase deviation is positive, at least one first reference power module is identified as at least one target adjustment module. The first reference power module is a power module in the dual-input power supply device that supplies power to 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, and the sum of the module power corresponding to at least one first reference power module is greater than or equal to the adjustment power. The circuit relationship includes the power supply relationship. When the current phase deviation is negative, at least one second reference power module is identified as at least one target adjustment module. The second reference power module is a power module in the dual-input power supply device that supplies power to 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, and the sum of the module power corresponding to at least one second reference power module is greater than or equal to the adjustment power. By constructing phase screening, power quantization, and module screening, a target adjustment module is selected based on the phase deviation of the current power distribution module. The first or second reference power module is determined as the target adjustment module based on the phase deviation and the adjustment power. This effectively solves the three-phase imbalance problem when using a three-phase current distribution unit with a dual-input power supply, thereby ensuring the three-phase balance inside the dual-input power supply device.

[0074] As an optional approach, the cabinet deviation corresponding to the dual-input power supply equipment is determined based on 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, including:

[0075] S3-1, obtain the phase average power based on the total power of the three phases, and determine the phase total power with the largest absolute value among the three phase total powers as the phase reference power;

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

[0077] S3-3, determine the cabinet deviation based on the ratio of the power difference to the sum of the total power of the three phases.

[0078] Optionally, in this embodiment, the phase reference power may be, but is not limited to, the total power of the phase with the largest absolute value selected from the total power of the three phases, and may be, but is not limited to, used to reflect the phase with the most significant deviation in the three-phase load of the cabinet. By determining the most unbalanced phase in the three-phase load of the cabinet, and using the total power of that phase as a reference parameter, it is ensured that the cabinet deviation calculated subsequently 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 this embodiment, the total phase power of each of the three phases in the dual-input power supply device is first collected, and the phase average power of the three phases is calculated. Then, the phase total power with the largest value is selected from the three phase total power and determined as the phase reference power. The phase average power is used to determine the benchmark for evaluating the degree of imbalance, and the main phase of the three-phase imbalance in the cabinet is also determined by the phase reference power.

[0080] Next, using the determined phase reference power and phase average power, the power difference between the two is obtained, and the cabinet deviation 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 average phase power and the phase reference power based on the total power of the three phases, and then obtaining the power difference between the two, the cabinet deviation is finally determined based on the ratio of the power difference to the sum of the total power of the three phases. This effectively avoids the problem of focusing only on the local balance of a single current distribution unit while ignoring the global balance of the cabinet, thereby improving the accuracy of performing three-phase balance on dual-input power supply equipment.

[0082] This application's embodiments obtain the average phase power based on the total power of the three phases, and determine the total phase power with the largest absolute value among the three phase total power as the phase reference power; obtain the power difference between the phase reference power and the average phase power; and determine the cabinet deviation based on the ratio of the power difference to the sum of the three phase total power. By calculating the average phase power and the phase reference power based on the total power of the three phases, obtaining the power difference between the two, and finally determining the cabinet deviation based on the ratio of the power difference to the sum of the three phase total power, the problem of focusing only on the local balance of a single current distribution unit while ignoring the global balance of the cabinet is effectively avoided, thereby improving the accuracy of performing three-phase balancing on dual-input power supply equipment.

[0083] As an alternative approach, adjustment conditions are determined based on rack offset, including at least one of the following:

[0084] S4-1: Obtain the load changes of each server in the dual-input power supply device at different time periods, and determine the adjustment conditions based on the load changes and the rack deviation.

[0085] S4-2: Obtain the heat changes of each server in the dual-input power supply device at different time periods, and determine the adjustment conditions based on the heat changes and the rack deviation.

[0086] Optionally, in this embodiment, load changes may refer to, but are not limited to, fluctuations in power load caused by changes in the computing pressure and data processing volume of each server in the dual-input power supply device at different times. This may include, but is not limited to, changes in the server's CPU utilization, memory usage, or actual power consumption. For further illustration, taking CPU utilization as an example to illustrate load changes, consider a dual-input power supply device where Monday to Friday are peak business periods, with server 1's CPU utilization increasing from 30% to 85% and server 2's CPU utilization increasing from 25% to 75%. Saturday and Sunday are off-peak periods, with the utilization rates of servers 1 and 2 dropping to 10%.

[0087] Optionally, in this embodiment, the heat change may refer to, but is not limited to, the heat fluctuation of each server in the dual-input power supply device due to load changes, which is positively correlated with the server power consumption. It can be understood that if the heat generation is too high, it indicates that the server power consumption is also too high, and three-phase power balancing adjustment is required.

[0088] Optionally, in this embodiment, the server management system collects the load parameters of each server in the rack in real time at different time periods, analyzes and records the load fluctuation pattern of each server, and combines the rack deviation to dynamically set adjustment conditions according to the load fluctuation trend. During peak load periods, the threshold of the adjustment conditions is lowered to ensure timely response to imbalances caused by sudden load increases; during off-peak load periods, the threshold is raised to reduce unnecessary adjustment operations.

[0089] Optionally, in this embodiment, temperature data around each server is collected by temperature sensors inside the rack at different times. The relationship between server power consumption and heat generation is combined to analyze the heat changes of each server. Then, combined with the rack deviation, the adjustment condition threshold is appropriately lowered during periods of high heat to avoid further imbalance in load distribution due to decreased module efficiency. During periods of low heat, the threshold is raised to reduce the interference of adjustment on the system.

[0090] It should be noted that by separately acquiring the load and heat changes of each server in the dual-input power supply device at different time periods, and then dynamically determining the adjustment conditions in combination with the rack deviation, the problems of untimely adjustment during peak load or over-adjustment during off-peak periods are avoided. It also makes up for the limitations of only focusing on load and ignoring the impact of heat on the efficiency of the power module, ensuring that the adjustment conditions can match the actual needs of the dual-input power supply device under different operating scenarios.

[0091] This application embodiment acquires the load changes of each server in a dual-input power supply device over different time periods, and determines adjustment conditions based on the load changes and rack deviation. It also acquires the heat changes of each server in the dual-input power supply device over different time periods, and determines adjustment conditions based on the heat changes and rack deviation. By acquiring the load and heat changes of each server in the dual-input power supply device over different time periods, and then dynamically determining the adjustment conditions in conjunction with the rack deviation, it ensures that the adjustment conditions match the actual needs of the dual-input power supply device under different operating scenarios.

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

[0093] S5-1, Based on the power phase corresponding to the target adjustment module, at least one third reference power module is determined among the multiple 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.

[0094] S5-2, Based on the module power corresponding to each of at least one third reference power module, determine the judgment result used to indicate the feasibility of establishing a three-phase balance of a dual-input power supply device circuit;

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

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

[0097] Optionally, in this embodiment, the determination result may be, but is not limited to, based on the module power of the third reference power module, determining whether the circuit relationship of the target adjustment module can be adjusted to achieve three-phase balance of the dual-input power supply device circuit. This conclusion can serve as the basis for whether to perform circuit relationship adjustment, avoiding forced adjustment when the balance target cannot be achieved, reducing the impact of invalid operation on power supply stability, and ensuring that the adjustment operation aims at an achievable three-phase balance, thereby improving adjustment efficiency.

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

[0099] It should be noted that by determining the third reference power module with the same phase based on the power phase of the target adjustment module, and then judging the feasibility of three-phase balance by combining the module power of the third reference power module, the circuit relationship between the target adjustment module and the current distribution unit is adjusted when it is determined that three-phase balance can be established. This avoids invalid operation or power supply risk caused by blind adjustment, and also ensures that the adjustment operation always aims at the overall three-phase balance of the cabinet, thereby ensuring the balance and stability of power supply to dual-input power supply equipment.

[0100] In this embodiment, based on the power phase corresponding to the target adjustment module, at least one third reference power module is determined among the multiple 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 is determined to indicate the feasibility of establishing three-phase balance of the dual-input power supply device circuit; if the determination result indicates that three-phase balance of the dual-input power supply device circuit can be established, the circuit relationship between at least one target adjustment module and the current current distribution unit is adjusted.

[0101] As an optional approach, based on the module power corresponding to at least one third reference power module, a determination result is made to indicate the feasibility of establishing a three-phase balance for a dual-input power supply device circuit, including:

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

[0103] S6-2, in at least one third reference module, the power supply module that is not the first target module is identified as at least the second target module;

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

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

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

[0107] S6-6, Based on the module power corresponding to at least one first target module and the module power corresponding to at least one second target module, determine a set of absolute power values, wherein the set of absolute power values ​​includes the absolute value of the difference between the module power corresponding to any first target module and the module power corresponding to any second target module;

[0108] S6-7, if the total power difference is less than the minimum value in the set of absolute power values, the judgment result is determined as a failure to establish three-phase balance of the dual-input power supply device circuit.

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

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

[0111] Optionally, in this embodiment, the set of absolute power values ​​may be, but is not limited to, a set of absolute values ​​of the difference between the module power of any first target module and the module power of any second target module, and may be, but is not limited to, used to reflect the difference in minimum power adjustment units between the two types of modules.

[0112] Optionally, in this embodiment, the circuit relationship between the third reference module and the current PDU is first clarified, and it is determined whether the module is powered by the current current distribution unit by reading the module's status word; power modules whose status words indicate that they are powered by the current current distribution unit are filtered out and identified as the first target modules. Within the scope of the third reference module, the modules already identified as the first target modules are excluded, and the remaining modules that have a power supply relationship with other current distribution units are identified as the second target modules.

[0113] Next, all first target modules are traversed, and the real-time module power of each module is collected. These power values ​​are summed, and the resulting total is the first total power, which represents the actual load scale of the corresponding phase of the current distribution unit. Then, all second target modules are traversed, and the real-time module power of each module is collected. These power values ​​are summed, and the resulting total is the second total power, which represents the actual load scale of the corresponding phase of other current distribution units. Finally, the total power difference is obtained by calculating the absolute difference between the first and second total powers, thus obtaining the load difference value between the current current distribution unit and the corresponding phases of other current distribution units.

[0114] Finally, a set of absolute values ​​of the power difference between the first target module and the second target module is constructed. That is, the power difference between each first target module and the power of each second target module is calculated and the absolute value is taken. After removing duplicates from all results, a set of absolute values ​​is formed. Then, 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, calculating the first total power and the second total power of the two types of modules respectively, and obtaining the total power difference, then constructing a set of absolute values ​​of the power of the two types of modules and extracting the minimum value, it is determined that three-phase balance cannot be established when the total power difference is less than the minimum value. This effectively avoids power supply fluctuations caused by forced operation when there is no adjustment space or insufficient adjustment accuracy, and ensures the stable operation of the power supply system of the dual-input power supply equipment.

[0116] In this embodiment, based on the circuit relationship between at least one third reference module and the current current distribution unit, at least one first target module is determined from the at least one third reference module, wherein the first target module and the current current distribution unit have a power supply relationship, and the circuit relationship includes the power supply relationship; power supply modules that are not first target modules among the at least one third reference module are determined as at least second target modules; the module power corresponding to each of the first target modules is summed to obtain a first total power; the module power corresponding to each of the second target modules is summed to obtain a second total power; the total power difference between the first total power and the second total power is obtained; 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 set of absolute power values ​​is determined, wherein the set of absolute power values ​​includes the absolute value of the difference between the module power corresponding to any first target module and the module power corresponding to any second target module; if the total power difference is less than the minimum value in the set of absolute power values, the determination result is determined as a failure to establish three-phase balance of the dual-input power supply device 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, and the difference in total power is obtained. Then, the absolute value set of the power of the two types of modules is constructed and the minimum value is extracted. Finally, when the difference in total power is less than the minimum value, it is determined that the three-phase balance cannot be established. This effectively avoids power supply fluctuations caused by forced operation when there is no adjustment space or insufficient adjustment accuracy, and ensures the stable operation of the power supply system of the dual-input power supply equipment.

[0117] As an alternative, at least one target adjustment module is identified from a plurality of power modules included in a dual-input power supply device, including:

[0118] S7-1, a sorted list is obtained based on three phase deviations, and the first phase deviation in the sorted list is determined as the target phase deviation. The sorted list is determined based on the absolute values ​​of the three phase deviations.

[0119] S7-2, when the target phase deviation meets the adjustment conditions, at least one target adjustment module is determined from the multiple power modules included in the dual-input power supply device;

[0120] S7-3, if the target phase deviation does not meet the adjustment conditions, the next phase deviation in the sorting list will be determined as the target phase deviation.

[0121] Optionally, in this embodiment, the sorting list may be, but is not limited to, a list formed by sorting the three phase deviations in descending order of their absolute values, with the sorting based on the absolute value of the deviation to highlight the phase with the most severe imbalance. By clearly defining the priority of each phase imbalance, it ensures that the phase with the most severe deviation is addressed first, avoiding unresolved key issues due to disordered adjustment and improving the efficiency of balance adjustment.

[0122] To illustrate further, suppose the absolute values ​​of the three phase deviations are 6.67%, 0.2%, and 6.67%, respectively. After sorting them from largest to smallest absolute value, the sorted list is [6.67%, 6.67%, 0.2%].

[0123] Optionally, in this embodiment, the target phase deviation can be, but is not limited to, the phase deviation currently being evaluated for adjustment from a sorted list. Initially, the first element in the list can be understood as the phase deviation with the largest absolute value. If the adjustment conditions are not met, the next element is selected sequentially. By clearly identifying the phase that currently requires focus and evaluating whether it meets the adjustment conditions, it is determined whether to initiate the module adjustment process for that phase, ensuring that the adjustment operation focuses on the phase that most needs improvement.

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

[0125] Next, the target phase deviation is compared with the adjustment conditions. If the conditions are met, the corresponding power supply module is selected according to the type of the target phase: if the target phase load is too high, the power supply module powered by the current current distribution unit under that phase is selected as the target adjustment module; if the load is too low, the power supply module connected to other current distribution units under that phase is selected as the target adjustment module.

[0126] If the target phase deviation does not meet the adjustment conditions, the next phase deviation is taken from the sorting list as the new target phase deviation, and the evaluation process is repeated; if all phase deviations do not meet the conditions, it is determined that no balancing adjustment needs to be initiated.

[0127] It should be noted that by generating a sorted list based on the absolute values ​​of the three phase deviations and determining the target phase deviations in sequence, the target adjustment module is selected when the target phase deviation meets the adjustment conditions, and the next phase deviation is polled when it does not meet the conditions. This achieves the priority handling of the most serious phase imbalance problem in the three-phase balance adjustment of dual-input power supply, while avoiding the omission of other potential adjustment needs. This improves the targeting and efficiency of three-phase balance adjustment, thereby ensuring the balanced and stable operation of the power supply system of dual-input power supply equipment.

[0128] In this embodiment, a sorted list is generated based on three phase deviations, and the first phase deviation in the sorted list is determined as the target phase deviation. The sorted list is determined based on the absolute values ​​of the three phase deviations. If the target phase deviation meets the adjustment conditions, at least one target adjustment module is determined from the multiple power modules included in the dual-input power supply device. If the target phase deviation does not meet the adjustment conditions, the next phase deviation in the sorted list is determined as the target phase deviation. By generating a sorted list based on the absolute values ​​of the three phase deviations and sequentially determining the target phase deviations, and selecting the target adjustment module when the target phase deviation meets the adjustment conditions and polling the next phase deviation when it does not, the most severe phase imbalance problem is prioritized in the three-phase balance adjustment of the dual-input power supply, while avoiding the omission of other potential adjustment needs. This improves the targeting and efficiency of the three-phase balance adjustment, thereby ensuring the balanced and stable operation of the power supply system of the dual-input power supply device.

[0129] As an optional approach, the phase deviation of the current distribution unit in each of the three current phases is determined based on the deviation between the phase power corresponding to each of the three current phases and the first reference phase power, including:

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

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

[0132] S8-3, Based on the ratio of the first difference to the sum of phase power, determine the phase deviation corresponding to the first phase;

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

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

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

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

[0137] Optionally, in this embodiment, the real-time phase power of the three phases of the dual-input power supply device is collected, and the sum of the three phases is obtained by addition and determined as the phase power sum, thereby reflecting the current total power load of the cabinet.

[0138] Next, select the first phase out of the three phases, subtract the reference phase power from its phase power to obtain the first difference value. The sign of this difference value reflects the load level. Divide the obtained first difference value by the sum of the phase powers to obtain the first phase deviation. Select the second phase out of the three phases, subtract the reference phase power from its phase power to obtain the second difference value, and divide the obtained second difference value by the sum of the phase powers to obtain the second phase deviation. Select the third phase out of the three phases, subtract the reference phase power from its phase power to obtain the third difference value, and divide the obtained third difference value by the sum of the phase powers to obtain the first phase deviation.

[0139] It should be noted that by summing the power of the three phases to obtain the sum of phase power, calculating the difference between the power of each phase and the reference phase, and then determining the deviation of each phase by the ratio of the difference to the sum of phase power, a comprehensive and quantitative assessment of the three-phase load imbalance of the dual-input power supply equipment is achieved, providing a numerical basis for subsequent three-phase balance adjustment.

[0140] This application's embodiments involve summing the power of three phases to obtain a sum of phase power; obtaining a first difference between the phase power corresponding to the first phase and the reference phase power; determining the phase deviation corresponding to the first phase based on the ratio of the first difference to the sum of phase power; obtaining a second difference between the phase power corresponding to the second phase and the reference phase power; determining the phase deviation corresponding to the second phase based on the ratio of the second difference to the sum of phase power; obtaining a third difference between the phase power corresponding to the third phase and the reference phase power; and determining the phase deviation corresponding to the third phase based on the ratio of the third difference to the sum of phase power. By summing the power of the three phases to obtain a sum of phase power, calculating the difference between each phase and the reference phase power, and then determining the ratio of the difference to the sum of phase power as the phase deviation, a comprehensive and quantitative assessment of the three-phase load imbalance of a dual-input power supply device is achieved, providing a numerical basis for subsequent three-phase balance adjustment.

[0141] As an optional solution, in order to better understand the process of the three-phase balancing method of the above-mentioned dual-input power supply device, the following describes the execution flow of the three-phase balancing method of the above-mentioned dual-input power supply device in conjunction with optional embodiments, but it is not intended to limit the technical solution of the embodiments of this application.

[0142] First, add a controller, current sensors, and voltage sensors to the rack. The controller can be a remote controller or one of the servers in the rack. The current sensors acquire the input current of each phase of the three-phase power supply, and the voltage sensors acquire the voltage of each phase. The data acquired by the current and voltage sensors can be directly transmitted to the controller; when the controller is a remote controller, the data can be transmitted to it via a management switch. The controller can communicate with the server through the management switch and can issue commands to control the input switching of each power module.

[0143] Next, a power module operating status flag, denoted as T, is added. The operating status of the power modules on the server is represented by two bytes. A bit set to 1 in the PDU status word indicates that the PDU is operating, and a bit set to 1 in the phase status word indicates that a specific phase is operating. Other bits are set to the default value of 0. Thus, the status of each power module can be represented by the following six possibilities, which in hexadecimal are T = 0x11, 0x12, 0x14, 0x21, 0x22, or 0x24. The power of each power supply is denoted as P1…Pm, where m is the total number of power supplies. The i-th power module is then represented by its operating status flag character Ti and its power Pi. Since the PSU can switch inputs, it can switch between inputs from PDU1 or PDU2. That is, the high-order bits 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-position state (phase) cannot be switched because the connection method between each server input cable and the PDU is fixed during rack installation.

[0144] Then, the power of the PDU and each phase is statistically analyzed using the operating status flags. The power values ​​of the PDU or PDU phases are determined by summing the power values ​​corresponding to the status flags. For example, to calculate the total power of phase A of PDU1, simply sum all the power values ​​with status flag 0x11, denoted as P11. Similarly, P11, P12, P14, P21, P22, and P24 can be calculated. The total power of all phase A phases can be calculated by summing all the power values ​​with lower bits set to 1 (0x11 & 0x21), denoted as Pa. Similarly, Pb and Pc can be calculated. The total power of PDU1 can be calculated by summing all the power values ​​with higher bits set to 1 (0x11 & 0x12 & 0x14), denoted as P1. The total power of PDU2 is denoted as P2.

[0145] The formula for calculating the phase A unbalance of PDU1 is shown in formula (1):

[0146] (1);

[0147] The formula for the phase B unbalance of PDU1 is shown in formula (2):

[0148] (2);

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

[0150] (3);

[0151] The formula for the phase A unbalance of PDU2 is shown in formula (4):

[0152] (4);

[0153] The formula for the phase B unbalance of PDU2 is shown in formula (5):

[0154] (5);

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

[0156] (6).

[0157] The control system monitors the voltage and current values ​​of each phase on PDU1 and PDU2 by switching the operating input lines of PSUi. It determines the corresponding operating status flag of PSUi by observing a decrease in the power value of one phase and an increase in the power value of another. The process is as follows: Figure 3 As shown:

[0158] S302, obtain the power Pi of power module i;

[0159] S304, obtain the power module i at input 1;

[0160] S306, the host computer controls the power module i to switch to input 2;

[0161] S308, whether the current of current distribution unit 1 increases; if yes, execute S310, otherwise execute S312.

[0162] S310, determine that the high bit of power module i is 1;

[0163] S312, determine that the high bit of power module i is 2;

[0164] S314: Does the current in phase A increase? If yes, execute S316; otherwise, execute S318.

[0165] S316, determine that the low bit of power module i is 1;

[0166] S318: Does the current in phase B increase? If yes, execute S320; otherwise, execute S322.

[0167] S320, determine that the low bit of power module i is 2;

[0168] S322, determine that the low bit of power module i is 4;

[0169] S324, the host computer controls the power module i to switch to input 1;

[0170] S326, records the working status bit of power module i.

[0171] Optionally, in this embodiment, as Figure 4 The diagram illustrates an optional PSU and DPU connection method. Servers 402, 404, and 406 are located in the server rack. Server 402 contains power modules 408, 410, and 412; server 404 contains power modules 414, 416, and 418; and server 406 contains power modules 420, 422, and 424. Power modules 408, 410, and 412 in server 402 are connected to phase A of current distribution unit 426 and phase A of current distribution unit 428. Power modules 414, 416, and 418 in server 404 are connected to phase B of current distribution unit 426 and phase B of current distribution unit 428. Power modules 420, 422, and 424 in server 406 are connected to phase C of current distribution unit 426 and phase C of current distribution unit 428.

[0172] Taking this method as an example, the PSU operating status flag of a certain server can be 0x11 or 0x21. Under this input cable connection method, the power supply statistics at a certain moment are P1, P2, Pa, Pb, Pc, P11, P12, P14, P21, P22, P24, and the three-phase imbalance rate... , , , , At this moment, the ideal imbalance rate should be the three-phase imbalance rate of the entire cabinet calculated using Pa, Pb, and Pc, as shown in formula (7):

[0173] (7)

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

[0175] Optionally, the total regulated power value for operating state 11 is The power values ​​of the power modules currently in operating state 11 are denoted as P1, P2, P3, ..., Pn, and ordered by power magnitude as P1 > P2 > P3 > ... > Pn. The operating path 11 is switched to 21 and adjusted according to power magnitude until the adjusted power value is greater than Ps, i.e., P1 + P2 + ... + Pm > Ps, where m ≤ n. In other words, the power supplies corresponding to P1, P2, ..., Pm need to be switched from operating state 11 to 21.

[0176] Optionally, 0x11 and 0x21 can be adjusted to determine if the absolute value of the difference between two-phase power is less than the minimum difference between any two-phase PSU power. For example... > If P11-P12 is less than the minimum absolute value of the difference between the power supply power in any state 0x11 and the power supply power in any state 0x21. For example: the power supply power in state 0x11 is 1000W, 1000W, and 200W, and the power supply power in state 0x21 is 700W, 700W, and 700W. P11-P12=100W, while the minimum absolute value of the difference between the power supply power in any state 0x11 and the power supply power in any state 0x21 is 1000W-700W=300W. In this case, it means that the current in phase A cannot be more balanced by switching the power supply operating state.

[0177] After sorting, the two PSUs with the states furthest from the target value can quickly adjust the unbalanced phases on the PDU to a balanced state. This ensures that the three-phase unbalance rate of each PDU reaches its optimal state within any given time period, improving power supply balance and reliability on the line. The absolute values ​​of the unbalance are sorted, with the phase deviating the largest from the target value being adjusted first. Operating states 11 and 21 reach optimal balance. Once operating states 11 and 21 are balanced, the maximum value becomes [value missing], and then operating states 12 and 22 are adjusted to achieve optimal balance. If the phase with the maximum unbalance rate can no longer be optimized, the adjustment attempts to the phase with the minimum unbalance rate until the unbalance on all phases meets the requirements.

[0178] Further examples, such as Figure 5 As shown, the specific steps are as follows:

[0179] S502, obtain the operating status Ti of power module i;

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

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

[0182] S508 calculates the imbalance rate of each PDU in each phase;

[0183] S510, sort the imbalance rates based on the absolute value of each imbalance rate, and obtain the target imbalance rate with the largest absolute value;

[0184] S512, Does the target imbalance rate exceed the preset range? If yes, execute S514; otherwise, execute S504.

[0185] S514, can adjustments be made? If yes, execute S516; otherwise, execute S522.

[0186] S516, Is the target imbalance rate greater than 0? If yes, execute S518; otherwise, execute S520.

[0187] S518 switches a power module that is phase-matched to the target imbalance rate but has a mismatched power supply to be powered by a power supply that is matched to the target imbalance rate.

[0188] S520 switches a power module that is phase-matched and power-matched with the target imbalance rate to one that is not powered by the target imbalance rate.

[0189] S522, select another imbalance rate.
