Description

Technical Field

[0001] The present application belongs to the field of intelligent control technology, and in particular, relates to an intelligent control method and related devices for an uninterruptible power supply. Background Art

[0002] An uninterruptible power supply (UPS) is a power supply device that contains an energy storage device and can provide uninterrupted power supply. The UPS is mainly used to provide power supply to special equipment that has high requirements for power stability to ensure that the special equipment is not affected by power fluctuations such as the mains power. That is to say, when the UPS is used to supply power to special equipment, if the mains power input connected to the UPS is normal, the UPS will stabilize the mains power and supply it to the special equipment for use. At the same time, the UPS will also charge the energy storage device inside the machine for emergency use; if the mains power connected to the energy storage device is interrupted (accidental power outage), the UPS can immediately convert the electric energy of the energy storage device to continue the power supply to the special equipment, so that the special equipment can maintain normal operation and protect the software and hardware of the special equipment from damage.

[0003] However, for a low-power uninterruptible power supply, the battery capacity in its energy storage device is limited, and the output power that can be output is also limited. In order to adapt to different power demands, when the power demand is greater than the output power of a certain power supply, the existing technology often requires replacing a higher-power uninterruptible power supply, which is costly and will cause a waste of resources of the previously deployed low-power uninterruptible power supply.

[0063] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0064] See also Figure 6 The intelligent control system for managing several uninterruptible power supplies in this application mainly includes: a controller, a charging module, a unified external power supply interface module, a memory ( Figure 6 The controller is mainly used to coordinate the charging module to use the mains power to connect several uninterruptible power supplies (such as Figure 6 The uninterruptible power supply 1, uninterruptible power supply 2, uninterruptible power supply 3, ...) shown in the figure are used for charging management, and the external power supply interface module is coordinated to charge several external power supply interfaces (such as Figure 6 The external power supply interface 1, external power supply interface 2, external power supply interface 3, ...) shown in the figure manages the external power supply. When the mains power is available, the charging module is controlled to directly provide power to the target load device through the unified external power supply interface module. When the mains power is missing, the unified external power supply interface module is controlled to obtain power from one or more uninterruptible power supplies to provide to the target load device; the memory is mainly used to store strategies such as charging and discharging management of the uninterruptible power supply, and record the charging status, discharging status, battery capacity, environmental parameters, charging and discharging times and other data of each uninterruptible power supply. The number of uninterruptible power supplies of the intelligent control system in this embodiment can be increased or decreased according to actual needs, and is not specifically limited here.

[0065] Based on the above understanding, please refer to Figure 1 , the present application is applied to an embodiment of an intelligent control method for managing an intelligent control system of X uninterruptible power supplies, where X is a positive integer greater than 1, including:

[0066] 101. Determine the target required power of the target load device that the intelligent control system needs to power.

[0067] In this embodiment, the intelligent control system provides power to the outside through a unified external power supply interface module. The unified external power supply interface module generally includes a plurality of external power supply interfaces, each of which can be controlled to connect to any one or more cascaded uninterruptible power supplies, and each external power supply interface can collect the dynamic current of the load device connected thereto, so that the intelligent control system can calculate the dynamic power demand of the load device based on the dynamic current, and regard the dynamic power demand as the target power demand. The dynamic power demand is equal to the dynamic current of the load device multiplied by the dynamic voltage. For example, assuming that the load device is an industrial computer with a rated power of 1000 watts, the intelligent control system of this embodiment obtains a dynamic current of 4.6 amps and a dynamic voltage of 220 volts through the external power supply interface through the unified external interface module, then the target power demand is 1000 watts or 1012 watts. If the maximum output power of each uninterruptible power supply is 300 watts, at least 4 uninterruptible power supplies are required to be cascaded to provide power to the industrial computer. Usually the dynamic power is changing, and this step needs to be executed periodically. If the dynamic power is greater than the rated power, the target demand power takes the dynamic power; if the dynamic power is less than or equal to the rated power, the target demand power takes the rated power, so that the subsequent steps of cascading multiple uninterruptible power supplies are also dynamic to cope with dynamic power demand, and at the same time, unused uninterruptible power supplies are released in time as unallocated to improve utilization efficiency. The intelligent control system can pre-record the rated power of the load device connected through each external power supply interface, or obtain the real-time current and real-time voltage through the external power supply interface in real time to calculate the real-time power. The real-time power is equal to the product of the real-time current and the real-time voltage. The above-mentioned rated power or real-time power can be regarded as the demand power of the load device connected to the external power supply interface. The target load device is the load device connected to the intelligent control system through a certain external power supply interface, and the target demand power is the rated power or real-time power of the target load device connected to the external power supply interface.

[0068] 102. Determine whether the target power demand is greater than the maximum output power that can be provided by any uninterruptible power supply in the intelligent control system. When the target power demand is greater than the maximum output power that can be provided by any uninterruptible power supply in the intelligent control system, execute step 103; when the target power demand is less than or equal to the maximum output power that can be provided by any uninterruptible power supply in the intelligent control system, execute step 104.

[0069] It should be noted that in order to maximize the use of the electric energy of each uninterruptible power supply and give full play to the value of each uninterruptible power supply, this embodiment needs to first determine whether the target demand power is greater than the maximum output power that can be provided by any uninterruptible power supply in the intelligent control system, so as to determine whether any uninterruptible power supply in the intelligent control system cannot independently meet the power demand of the target load device. When the target demand power is greater than the maximum output power that can be provided by any uninterruptible power supply in the intelligent control system, it proves that any uninterruptible power supply in the intelligent control system cannot independently meet the power demand of the target load device; when the target demand power is less than or equal to the maximum output power that can be provided by any uninterruptible power supply in the intelligent control system, it proves that any uninterruptible power supply in the intelligent control system can independently meet the power demand of the target load device.

[0070] 103. According to the target required power, Y uninterruptible power supplies are cascaded to provide power for the target load equipment. After the Y uninterruptible power supplies are cascaded, they can output an output power greater than the target required power.

[0071] It is worth noting that in this embodiment, Y is a positive integer greater than 1 and less than or equal to X. In this embodiment, Y uninterruptible power supplies are cascaded according to the target power demand, which means that the intelligent control system controls the unified external interface module through the controller to connect and control the discharge output of Y uninterruptible power supplies (selecting dynamic connection operations such as parallel and / or series connection according to actual needs), thereby achieving an increase in the maximum output power (for example, the output voltage can be increased by using the series connection method, and the output current can be increased by using the parallel connection method, etc.), so that the Y uninterruptible power supplies can output an output power greater than the target power demand after being cascaded. When step 102 determines that any uninterruptible power supply in the intelligent control system cannot meet the power demand of the target load device alone, this step cascades Y uninterruptible power supplies according to the target power demand and provides power to the target load device, thereby realizing the intelligent control of the reasonable use of multiple uninterruptible power supplies for cascading, improving the adaptability of the uninterruptible power supply to high power demand scenarios, and improving the utilization efficiency of small-power uninterruptible power supplies. The Y uninterruptible power supplies of this embodiment are idle uninterruptible power supplies that have not been allocated (not bound to supply power to a load device with an external power supply interface) among the X uninterruptible power supplies. The target demand power of the above-mentioned target load device should be less than the maximum output power that the X uninterruptible power supplies can provide.

[0072] In another embodiment, Figure 2After step 201, in order to ensure that the target load device can operate normally, the target load device is given more power redundancy to cope with the power demand of the target load device in overload operation. In this step, the target demand power can also be expanded by a preset multiple to obtain a target safety power. The preset multiple is usually between 1.1 and 1.2 times, that is, the target safety power W out The following relationship exists between the target required power W: 110%×W<W out <120%×W, target safe power W out It is the power that should be output after multiple uninterruptible power supplies are cascaded in the subsequent steps of this embodiment. The target required power W is one of the maximum output power, rated power or dynamic power of the target load device. Then, the K unallocated uninterruptible power supplies are sorted in priority allocation order according to a preset rule to obtain a priority allocation order of the K uninterruptible power supplies, where K is a positive integer greater than 0 and less than or equal to X; the corresponding maximum output powers of the K uninterruptible power supplies are accumulated one by one from the beginning according to the priority allocation order, and the new accumulated maximum output power obtained by accumulating one uninterruptible power supply each time is compared with the target safety power; when it is determined that the new accumulated maximum output power is less than or equal to the target safety power, the corresponding maximum output power of the next uninterruptible power supply among the K uninterruptible power supplies is accumulated according to the priority allocation order, and the new accumulated maximum output power obtained by accumulating one uninterruptible power supply each time is compared with the target safety power, and this cycle is repeated until it is determined that the new accumulated maximum output power is greater than the target safety power, then the accumulation of the corresponding maximum output power of the next uninterruptible power supply is stopped, and the Y uninterruptible power supplies that have been accumulated and calculated are cascaded to provide power supply to the target load equipment. The preset rules of this embodiment are: sorting from high to low according to the remaining battery power of K uninterruptible power supplies; or, sorting from few to many according to the number of times the batteries of K uninterruptible power supplies are used; or, sorting according to the preset serial number sequence of K uninterruptible power supplies. In another embodiment, in order to comprehensively optimize and extend the battery life of multiple uninterruptible power supplies in the intelligent control system, while trying to use a smaller number of uninterruptible power supplies for cascade output of electrical energy, and ensuring that the target load equipment has sufficient power, the preset rules can also be set as follows: first sorting from high to low according to the remaining battery power of K uninterruptible power supplies; when there is a consistency in the remaining battery power, then sorting from few to many according to the number of times the batteries of K uninterruptible power supplies are used; when there is a consistency in the remaining battery power and the number of times the batteries are used, sorting according to the preset serial number sequence of K uninterruptible power supplies; the preset serial number values ​​of K uninterruptible power supplies are different, and the preset serial number values ​​of K uninterruptible power supplies can be customized by the user.

[0073] 104. Select an unallocated idle uninterruptible power supply in the intelligent control system to provide power to the target load equipment.

[0074] When step 102 proves that any uninterruptible power supply in the intelligent control system can independently meet the power demand of the target load device, this step selects an unallocated idle uninterruptible power supply in the intelligent control system to provide power to the target load device, thereby realizing flexible selection of uninterruptible power supplies in the intelligent control system. Specifically, this step can select an uninterruptible power supply with the highest remaining battery power and the least number of battery uses from the unallocated idle uninterruptible power supplies as the target load device to provide power, thereby maximizing the safety of the operation of the target load device.

[0075] Based on the above Figure 1 According to the understanding of the embodiment, after the target required power of the target load device that the intelligent control system needs to power is determined in step 101, and before step 102 determines whether the target required power is greater than the maximum output power that can be provided by any uninterruptible power supply in the intelligent control system, an embodiment of the intelligent control method of the intelligent control system applied to manage X uninterruptible power supplies includes: 201, determining K uninterruptible power supplies that are not allocated among the X uninterruptible power supplies managed by the intelligent control system.

[0076] It should be noted that, in order for the intelligent control system of this embodiment to be able to execute, there must be K unallocated uninterruptible power supplies among the X uninterruptible power supplies managed by the intelligent control system, where K is a positive integer greater than 0 and less than or equal to X.

[0077] 202. Determine whether the maximum output power that can be provided by the K uninterruptible power supplies is greater than the target required power. If the maximum output power that can be provided by the K uninterruptible power supplies is greater than the target required power, trigger step 203; if the maximum output power that can be provided by the K uninterruptible power supplies is equal to or less than the target required power, trigger step 204.

[0078] It is worth noting that the maximum output power that can be output by the K uninterruptible power supplies that are not allocated to the intelligent control system is also limited. When using a certain external power supply interface of the intelligent control system to provide power to the target load equipment, it is necessary to determine whether the maximum output power that can be provided by the K uninterruptible power supplies is greater than the target required power required by the target load equipment. If the maximum output power that can be provided by the K uninterruptible power supplies is greater than the target required power, it can be set to provide power to the target load equipment to cope with the risk of power outage; if the maximum output power that can be provided by the K uninterruptible power supplies is equal to or less than the target required power, it cannot be set to provide power to the target load equipment, otherwise, when facing power outage, it will not be able to provide sufficient power output guarantee.

[0079] 203. Trigger execution of step 102.

[0080] When it is determined in step 202 that it can be set to provide power to the target load device to cope with the risk of loss of mains power, this step triggers execution Figure 1 Step 102 of the embodiment.

[0081] 204. Issue a warning.

[0082] When it is determined in step 202 that the target load device cannot be set to provide power, this step issues a warning, which may be one or more of a voice reminder, a screen pop-up reminder, and a light warning, and refuses to be set to provide power to the target load device, giving priority to ensuring the power supply of other load devices that have been set.

[0083] This embodiment does not have any special requirements for the target load device. As long as it is connected to the external power supply interface of the intelligent control system and the required rated power is input, this embodiment can automatically ensure a stable power supply to the target load device within a certain period of time when the mains power is lost.
