The core of the invention is to provide a power supply control method, which can realize three-phase load balance even if a failed PSU exists, eliminate the influence on the stable work of a power grid and eliminate potential safety hazards; another core of the present invention is to provide a power control apparatus, a device, and a computer-readable storage medium, which can achieve three-phase load balancing even if there is a faulty PSU, thereby eliminating the influence on the stable operation of the power grid and eliminating the potential safety hazard.
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a schematic flow chart of a power control method provided in the present invention, the power control method includes:
step S1: judging whether a server power supply PSU in a power supply system fails or not;
specifically, in view of the technical problems in the background art, in order to solve the three-phase load balancing problem in the case of a PSU failure, it is first necessary to monitor whether a PSU failure occurs in a power supply system, so as to trigger subsequent control steps and implement three-phase load balancing in the case of a PSU failure.
The power supply system refers to a power supply system of a rack server, and usually includes at least three groups of PSUs, and the number of PSUs in each group is at least 2, so as to prevent a situation that no PSU works in the phase and three-phase loads are greatly unbalanced due to a failure of one PSU.
Step S2: if so, determining the power compensation value of each PSU without faults according to the distribution information of the PSUs without faults in the power supply system and the total power value of the cabinet type server;
specifically, considering that in the case of a faulty PSU in the power supply system, the output power of each phase is already not in the original balanced state, but enters an unbalanced state, that is, the output power on the three phases is not equal, which is harmful to the normal and stable operation of the power grid, therefore, it is necessary to perform three-phase load balancing adjustment based on the fault-free PSU in the power supply system, that is, to make the output power on each phase equal based on the fault-free PSU in the power supply system, and therefore, it is necessary to perform power compensation (which may be increased or decreased) on the current fault-free PSU in the power supply system, so that the output power of the three phases are equal, so as to achieve three-phase balance, in order to calculate the power compensation value of the fault-free PSU, the first information to be obtained is the distribution information of the fault-free PSU, that is the fault-free PSU in each phase, and the total power value of the rack server (so that the total output power of the, thereby triggering the subsequent steps to equally distribute the total power value to the fault-free PSUs on each item and realizing three-phase load balance.
The total power value of the rack server may be obtained in various ways, for example, the total power value may be preset in the processor, and a worker needs to store the total power value in a storage device that can be obtained by the processor in advance.
Step S3: determining a target voltage value of each PSU without faults according to the power compensation value;
specifically, for the PSU, if the output power value is to be controlled, the output power value can be quickly and accurately controlled by controlling the output voltage value, so that the step can determine the target voltage value of each PSU according to the power compensation value, so as to adjust the output power of each PSU based on the control of the output voltage value of each PSU in the subsequent target.
Step S4: and controlling each PSU to adjust the output voltage value of each PSU to the corresponding target voltage value so as to enable the single-phase output power value corresponding to each phase of electricity to be equal.
Specifically, since the target voltage value determined in the above step is obtained according to the power compensation value, in this step, it is only necessary to control each PSU to adjust its output voltage value to its corresponding target voltage value, and the output power value of itself can be adjusted by the magnitude of its corresponding "power compensation value", for example, the power compensation value of PSU1 is +50W, the target voltage value determined according to this is 13V, and the current output voltage value of PSU1 is 12V, and in this step, the output voltage value of PSU1 can be adjusted to 13V, so that the effect of compensating the output power value of +50W for PSU1 can be obtained, thereby realizing three-phase load balance.
The invention provides a power supply control method, which can determine power compensation values of each non-fault PSU when a PSU in a power supply system has a fault, then convert the power compensation values into target voltage values of each PSU, and finally adjust the output voltage values of the non-fault PSUs to the corresponding target voltage values.
On the basis of the above-described embodiment:
as a preferred embodiment, determining the power compensation value of each PSU without a fault according to the distribution information of the PSUs without a fault in the power supply system and the total power value of the rack server specifically includes:
acquiring distribution information which is sent by each PSU and comprises the phase where each PSU is located and whether each PSU is in fault;
specifically, considering that the PSU itself can detect whether the PSU itself is faulty or not, and can also implement communication with other processors, in the embodiment of the present invention, the distribution information sent by each PSU can be directly obtained, and the details of the PSU on each phase can be determined by the distribution information including "the phase in which each PSU is located" and "whether the PSU is faulty or not", so as to determine the power compensation value according to the distribution information.
Of course, besides the distribution information, the distribution information may be of other various types, and the embodiment of the present invention is not limited herein.
Determining the total number of the fault PSUs, the total number of the single-phase PSUs on each phase and the sub-number of the fault PSUs on each phase according to the distribution information;
specifically, since the phase of each PSU and whether each PSU is faulty have been known in the above steps, in order to calculate the power compensation value of each PSU without fault, the total number of faulty PSUs, the total number of single-phase PSUs in each phase, and the total number of faulty PSUs in each phase need to be determined, and the subsequent steps may calculate the power compensation value of each PSU without fault based on these data.
The power compensation value for each PSU without failure is calculated by:
the total number of the single-phase PSUs on the three phases is equal, A is a power compensation value which needs to be increased by each PSU on the phase with the fault PSU, B is a power compensation value which needs to be reduced by each PSU on the phase without the fault PSU, S is a total power value, N is the total number of the single-phase PSUs on each phase, M is the total number of the fault PSUs, and M is the sub-number of the fault PSUs on the phase with the fault PSU.
Specifically, under normal conditions, the number of PSUs in three PSU groups corresponding to three phases is equal, and in the operation process, all PSUs operate in a current sharing mode by default, and because the initial output voltage values of the PSUs are equal, three-phase load balancing can be realized under the condition that no fault PSU existsThe above-described manner of operation between PSUs, in which the three-phase load balancing is controlled in the case of a "failed PSU", wherein,
it can be understood that the ideal output power value of each non-faulty PSU on the phase where the faulty PSU is present,
it can be understood that the actual output power value of each non-faulty PSU on the phase with faulty PSU, and therefore subtracting the above two values can obtain the power compensation value a that each PSU on the phase with faulty PSU needs to increase, and the same holds true for the calculation of B,
it can be understood that there is no actual output power value of each PSU on the phase of the faulty PSU, but
It will be appreciated that the ideal output power value for each PSU on the phase where no faulty PSU exists, and subtracting the two values will result in a reduced power offset value B for each PSU on the phase where no faulty PSU exists.
The method can quickly and accurately calculate the power compensation value of the fault-free PSU in the power supply system with the three-phase load balance as the target.
Of course, in addition to the above calculation methods, the calculation method of the power compensation value of the non-fault PSU in the power supply system with the three-phase load balance as the target may be of other various types, and the embodiment of the present invention is not limited herein.
As a preferred embodiment, the determining, according to the power compensation value, the target voltage value of each PSU without a fault specifically includes:
determining the output voltage compensation value of each PSU without faults according to the power compensation value and the control principle of the PSU;
specifically, when each PSU in the power supply system is in the current sharing mode, the output power value of each PSU can be controlled by controlling the output voltage value of each PSU, so that the power compensation value of each PSU can be converted into the output voltage compensation value according to the control principle of the PSU, and thus, the output voltage value of each PSU can be adjusted based on the output voltage compensation value, and the compensation control of the output power value of each PSU is conveniently realized.
The specific process of converting the power compensation value of each PSU into the output voltage compensation value based on the PSU control principle is a mature prior art, and the embodiment of the present invention is not described herein again.
And determining the target voltage value of each PSU without faults according to the output voltage compensation value and the rated voltage value of the cabinet server.
Specifically, the rated voltage value is the output voltage value of each PSU under normal conditions, the output voltage value is uniform under the condition of no fault PSU, and generally may be 12V, etc., and the target voltage value can be obtained by compensating the voltage compensation value to the current output voltage value (i.e., the rated voltage value), for example, when the voltage compensation value of PSU2 is +0.5V, the target voltage value of PSU2 may be 12.5V.
As a preferred embodiment, the determining whether there is a PSU failure in the power supply system specifically includes:
and judging whether the PSU in the power supply system has a fault or not by monitoring the fault report information of each PSU in the power supply system.
Specifically, the PSUs have a communication function, so that the fault reporting information of each PSU can be acquired through real-time communication with the PSUs, the judgment of whether the PSUs have faults or not is achieved, other hardware does not need to be added, and the method has the advantages of being fast, accurate and low in cost.
Of course, besides the specific manner, determining whether there is a PSU failure in the power supply system may be performed in other various specific manners, and the embodiment of the present invention is not limited herein.
As a preferred embodiment, it is applied to RMC (Router Manager Center).
Specifically, considering that the RMC in the rack server itself can communicate with each PSU in the power supply system, the use of the RMC in the rack server not only does not require an additional processor, but also does not require an additional communication line between the processor and each PSU, thereby saving cost.
Wherein each PSU may communicate with an RMC or other type of processor via a PMBUS (Power Management Bus) Bus.
Of course, the power control method in the embodiment of the present invention may be applied to other various processors besides the RMC, and the embodiment of the present invention is not limited herein.
As a preferred embodiment, after determining that there is a PSU failure in the power supply system, before determining a power compensation value of each PSU without failure according to distribution information of PSUs without failure in the power supply system and a total power value of the rack server, the power supply control method further includes:
calculating the three-phase unbalance degree of the power supply system according to the distribution information of the fault-free PSU in the power supply system and the total power value of the cabinet type server;
specifically, considering that a three-phase imbalance problem may occur in the case of a faulty PSU, but the three-phase imbalance of a smaller degree is tolerable for the power grid, in this case, the three-phase load may not be adjusted, the operation pressure of the processor may be reduced, and the rack server may also be enabled to operate under a rated voltage value.
Judging whether the three-phase unbalance is greater than a preset threshold value or not;
specifically, in order to accurately measure the three-phase unbalance according to a standard, the embodiment of the invention sets the preset threshold, and whether the three-phase unbalance can be tolerated by the power grid can be distinguished through comparison between the preset threshold and the three-phase unbalance, so that execution of subsequent steps is triggered conveniently.
The preset threshold may be set autonomously, for example, may be 100W, and the embodiment of the present invention is not limited herein.
And if so, determining the power compensation value of each PSU without faults according to the distribution information of the PSUs without faults in the power supply system and the total power value of the cabinet type server.
Specifically, the power grid is considered to be unable to tolerate the current three-phase load imbalance problem of the power supply system under the condition that the three-phase imbalance degree is greater than the preset threshold value, and then a subsequent three-phase load balance control process can be executed so as to ensure normal and stable operation of the power grid.
Of course, when the three-phase imbalance degree is not greater than the preset threshold, the operation may be ended and the monitoring of whether the faulty PSU exists is continued.
As a preferred embodiment, the calculating the three-phase imbalance of the power supply system according to the distribution information of the fault-free PSUs in the power supply system and the total power value of the rack server specifically includes:
in particular, the method comprises the following steps of,
can be understood as the ideal output power value on each phase, and
it can be understood as the actual value of the total output power of the single phase on the phase where the faulty PSU is present, then
It can be considered as an output power deviation value on the phase where the faulty PSU exists, for the same reason, because
It can be understood that there is no actual value of the total output power of the single phase on the phase of the faulty PSU, then
The output power deviation value on the phase where the faulty PSU is not present, the three-phase imbalance can be one of the two with the larger absolute value.
The three-phase unbalance degree of the power supply system can be rapidly and accurately calculated through the method.
