[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] See also Figure 1 , Figure 1 A flow chart of a UPS selection method provided by an embodiment of the present invention, the method comprising:

[0048] Step S11: when the target UPS is to supply power to each load, the long-term power of each load and the maximum instantaneous power of each load are obtained;

[0049] Step S12: determining the maximum long-term power of all loads and the maximum instantaneous power of all loads respectively according to the start-up timing of the long-term power of each load and the maximum instantaneous power of each load;

[0050] Step S13: selecting the long-term power characteristics and overload power characteristics of the target UPS according to the maximum long-term power of all loads and the maximum instantaneous power of all loads to obtain a selected UPS, and using the selected UPS to supply power to each load.

[0051] In order to enable those skilled in the art to more clearly understand the implementation principle of the present application, a simple description of the UPS selection method in the prior art is first given here. Figure 2 , Figure 2 This is a schematic diagram showing the long-term power of each sub-item load in a table. Figure 2 Only the long-term power of each load is considered. Figure 2 It can be seen from the content shown that the maximum long-term power of all sub-items is 809.6 W. If the UPS for powering each load is selected according to the conventional method in the prior art, the rated power of the UPS will be selected according to a margin of 1.3 times. At this time, the UPS will be set to a UPS with a rated power higher than 1052.5 W, and the UPS model will usually be set to 2kVA / 1.6kW and above.

[0052] However, the instantaneous power of each load may change greatly during operation, and may even far exceed the long-term power of the load, which may lead to inaccurate and unreliable UPS selection results. In order to avoid this technical problem, in this embodiment, a UPS selection method is provided, which can ensure the accuracy and reliability of UPS selection results by selecting UPS.

[0053] In this method, when the target UPS is to supply power to each load, the first step is to determine the long-term power of each load and the maximum instantaneous power of each load. Among them, long-term power refers to the average power consumption of the load over a period of time. This parameter reflects the average energy consumption level of the load over a certain period of time. Instantaneous power refers to the power consumption of the load at a specific moment. This parameter reflects the instantaneous change of load power and is usually related to the dynamic characteristics of the load. The fluctuation of instantaneous power is caused by factors such as the start, stop, and failure of the load.

[0054] Since the selection result of the target UPS is mainly determined by the maximum long-term power of all loads and the maximum instantaneous power of all loads, and the long-term power of the load and the instantaneous power of the load can characterize the dynamic change performance of the load power, after obtaining the long-term power of each load and the maximum instantaneous power of each load, the maximum long-term power of all loads and the maximum instantaneous power of all loads can be determined respectively according to the start-up timing of the long-term power of each load and the maximum instantaneous power of each load, and the long-term power characteristics and overload power characteristics of the target UPS are selected according to the maximum long-term power of all loads and the maximum instantaneous power of all loads to obtain the selected UPS.

[0055] When the selection result of the target UPS is determined and the selected UPS is obtained, the selected UPS can be used to power each load. In this selection method, because the selection result of the target UPS takes into account the maximum long-term power and the maximum instantaneous power of all loads, the selection result of the target UPS can be guaranteed to be more accurate and reliable.

[0056] Compared with the prior art, when using this method to select the target UPS, not only the long-term power of each load is considered, but also the maximum instantaneous power of each load is taken into account. This makes the UPS selection result more in line with the actual working conditions when the UPS supplies power to each load, thereby ensuring the accuracy and reliability of the UPS selection result.

[0057] Based on the above embodiment, this embodiment further illustrates and optimizes the technical solution. As a preferred implementation mode, the above steps of respectively determining the maximum long-term power of all loads and the maximum instantaneous power of all loads according to the start-up timing of the long-term power of each load and the maximum instantaneous power of each load include:

[0058] When the changing trends of the long-term power of each load remain consistent, and the changing trends of the maximum instantaneous power of each load remain consistent, the sum of the long-term power of each load is determined as the maximum long-term power of all loads, and the sum of the maximum instantaneous power of each load is determined as the maximum instantaneous power of all loads.

[0059] In this embodiment, when the maximum long-term power of all loads and the maximum instantaneous power of all loads are determined respectively according to the starting timing of the long-term power of each load and the maximum instantaneous power of each load, if the changing trend of the long-term power of each load remains consistent, and the changing trend of the maximum instantaneous power of each load is also consistent, then the sum of the long-term power of each load can be judged as the maximum long-term power of all loads, and the sum of the maximum instantaneous power of each load can be judged as the maximum instantaneous power of all loads.

[0060] See also Figure 3 , Figure 3 When the long-term power change trend of each load is consistent and the maximum instantaneous power change trend of each load is also consistent, the power superposition diagram of each load is shown. Figure 3 It can be seen that the long-term power of load 1, load 2 and load 3 are started at the same time, and the instantaneous power of load 1, load 2 and load 3 are also started at the same time. Among them, the long-term power of load 1 is 60W, the long-term power of load 2 is 80W, the long-term power of load 3 is 100W, the maximum instantaneous power of load 1 is 150W, the maximum instantaneous power of load 2 is 130W, and the maximum instantaneous power of load 3 is 200W.

[0061] Then, in this case, the maximum long-term power W1 of all loads is:

[0062] W1=60W+80W+100W=240W;

[0063] The maximum instantaneous power W2 of all loads is:

[0064] W2=150W+130W+200W=480W;

[0065] In practical applications, there is a special case where the above method can also be used to determine the maximum long-term power of all loads and the maximum instantaneous power of all loads. That is, when the long-term power of each load is zero and the change trend of the maximum instantaneous power of each load is consistent, the maximum long-term power of all loads can be determined to be zero, and the sum of the maximum instantaneous power of each load can be determined to be the maximum instantaneous power of all loads.

[0066] See also Figure 4 , Figure 4 This is a schematic diagram of the power superposition of each load when the long-term power of each load is zero and the change trend of the maximum instantaneous power of each load remains consistent. Figure 4 It can be seen that the long-term power of load 1 is zero, the long-term power of load 2 is zero, the long-term power of load 3 is zero, and the instantaneous power of load 1, load 2 and load 3 are started at the same time, among which the maximum instantaneous power of load 1 is 150W, the maximum instantaneous power of load 2 is 130W, and the maximum instantaneous power of load 3 is 200W.

[0067] Then, in this case, the maximum long-term power W1 of all loads is:

[0068] W1=0+0+0=0;

[0069] The maximum instantaneous power W2 of all loads is:

[0070] W2=150W+130W+200W=480W;

[0071] Obviously, through the technical solution provided in this embodiment, the maximum long-term power of all loads and the maximum instantaneous power of all loads can be accurately determined under the condition that the changing trend of the long-term power of each load remains consistent and the changing trend of the maximum instantaneous power of each load remains consistent.

[0072] Based on the above embodiment, this embodiment further illustrates and optimizes the technical solution. As a preferred implementation mode, the above steps of respectively determining the maximum long-term power of all loads and the maximum instantaneous power of all loads according to the start-up timing of the long-term power of each load and the maximum instantaneous power of each load include:

[0073] When the changing trends of the long-term power of each load remain consistent and the changing trends of the maximum instantaneous power of each load are inconsistent, the sum of the long-term power of each load is determined as the maximum long-term power of all loads, and the maximum instantaneous power of all loads is determined based on the maximum long-term power of all loads and the changing power of the maximum instantaneous power of each load compared with its own long-term power.

[0074] In this embodiment, when the maximum long-term power and the maximum instantaneous power of all loads are determined respectively according to the starting timing of the long-term power of each load and the maximum instantaneous power of each load, if the changing trend of the long-term power of each load remains consistent and the changing trend of the maximum instantaneous power of each load is inconsistent, then the sum of the long-term power of each load can be determined as the maximum long-term power of all loads, and the maximum instantaneous power of all loads can be determined according to the changing power of the maximum long-term power of all loads and the maximum instantaneous power of each load compared with its own long-term power.

[0075] See also Figure 5 , Figure 5 When the long-term power change trend of each load is consistent and the maximum instantaneous power change trend of each load is inconsistent, the power superposition diagram of each load is shown. Figure 5 It can be seen that the long-term power of load 1, load 2 and load 3 are started at the same time, while the instantaneous power of load 1, load 2 and load 3 are not started at the same time. Among them, the long-term power of load 1 is 60W, the long-term power of load 2 is 80W, the long-term power of load 3 is 100W, the maximum instantaneous power of load 1 is 150W, the maximum instantaneous power of load 2 is 130W, and the maximum instantaneous power of load 3 is 200W.

[0076] Then, in this case, the maximum long-term power W1 of all loads is:

[0077] W1=60W+80W+100W=240W;

[0078] The maximum instantaneous power W2 of all loads is:

[0079] W2=240W+max{(150-60)W, (130-80)W, (200-100)W}=340W;

[0080] In practical applications, there is a special case where the above method can also be used to determine the maximum long-term power of all loads and the maximum instantaneous power of all loads. That is, when the long-term power of each load is zero, and the change trend of the maximum instantaneous power of each load is inconsistent, the maximum long-term power of all loads can be determined to be zero, and the maximum change power of the maximum instantaneous power of each load compared to its own long-term power is determined as the maximum instantaneous power of all loads.

[0081] See also Figure 6 , Figure 6 This is a schematic diagram of the power superposition of each load when the long-term power of each load is zero and the change trends of the maximum instantaneous power of each load are inconsistent. Figure 6 It can be seen that the long-term power of load 1 is zero, the long-term power of load 2 is zero, the long-term power of load 3 is zero, and the instantaneous power of load 1, load 2 and load 3 are not started at the same time. Among them, the maximum instantaneous power of load 1 is 150W, the maximum instantaneous power of load 2 is 130W, and the maximum instantaneous power of load 3 is 200W.

[0082] Then, in this case, the maximum long-term power W1 of all loads is:

[0083] W1=0+0+0=0;

[0084] The maximum instantaneous power W2 of all loads is:

[0085] W2=0+max{(150-0)W, (130-0)W, (200-0)W}=200W;

[0086] Obviously, through the technical solution provided in this embodiment, the maximum long-term power of all loads and the maximum instantaneous power of all loads can be accurately determined when the changing trends of the long-term power of each load remain consistent and the changing trends of the maximum instantaneous power of each load are inconsistent.

[0087] Based on the above embodiment, this embodiment further illustrates and optimizes the technical solution. As a preferred implementation mode, the above steps of respectively determining the maximum long-term power of all loads and the maximum instantaneous power of all loads according to the start-up timing of the long-term power of each load and the maximum instantaneous power of each load include:

[0088] When the changing trends of the long-term power of each load are inconsistent, and the changing trends of the maximum instantaneous power of each load are inconsistent, the load with the largest long-term power is screened from all loads to obtain the long-term maximum load, and the long-term power of the long-term maximum load is determined as the maximum long-term power of all loads. At the same time, the load with the largest instantaneous power is screened from all loads to obtain the instantaneous maximum load, and the instantaneous power of the instantaneous maximum load is determined as the maximum instantaneous power of all loads.

[0089] In this embodiment, when the changing trends of the long-term power of each load are inconsistent, and the changing trends of the maximum instantaneous power of each load are inconsistent, in order to determine the maximum long-term power of all loads and the maximum instantaneous power of all loads, it is necessary to screen out the load with the largest long-term power from all loads to obtain the long-term maximum load, and judge the long-term power of the long-term maximum load as the maximum long-term power of all loads. At the same time, screen out the load with the largest instantaneous power from all loads to obtain the instantaneous maximum load, and judge the instantaneous power of the instantaneous maximum load as the maximum instantaneous power of all loads.

[0090] See also Figure 7 , Figure 7 This is a schematic diagram of the power superposition of each load when the long-term power change trends of each load are inconsistent and the instantaneous power change trends of each load are inconsistent. Figure 7 It can be seen that the long-term power of load 1, load 2 and load 3 are not started at the same time, and the instantaneous power of load 1, load 2 and load 3 are not started at the same time. Among them, the long-term power of load 1 is 60W, the long-term power of load 2 is 80W, the long-term power of load 3 is 100W, the maximum instantaneous power of load 1 is 150W, the maximum instantaneous power of load 2 is 130W, and the maximum instantaneous power of load 3 is 200W.

[0091] Then, in this case, the maximum long-term power W1 of all loads is:

[0092] W1=max{60W, 80W, 100W}=100W;

[0093] The maximum instantaneous power W2 of all loads is:

[0094] W2=max{150W, 130W, 200W}=200W;

[0095] Obviously, through the technical solution provided in this embodiment, the maximum long-term power of all loads and the maximum instantaneous power of all loads can be accurately determined when the changing trends of the long-term power of each load are inconsistent and the changing trends of the maximum instantaneous power of each load are inconsistent.

[0096] Based on the above embodiment, this embodiment further illustrates and optimizes the technical solution. As a preferred implementation mode, the above steps of respectively determining the maximum long-term power of all loads and the maximum instantaneous power of all loads according to the start-up timing of the long-term power of each load and the maximum instantaneous power of each load include:

[0097] The long-term power of each load and the maximum instantaneous power of each load are displayed using visualization tools, and the maximum long-term power of all loads and the maximum instantaneous power of all loads are determined according to the start-up timing of the long-term power of each load and the maximum instantaneous power of each load; wherein the visualization tools include: tables, line graphs and scatter plots.

[0098] In this embodiment, in order to enable those skilled in the art to more intuitively and accurately determine the maximum long-term power of all loads and the maximum instantaneous power of all loads, a visualization tool can be used to display the long-term power of each load and the maximum instantaneous power of each load, and the maximum long-term power of all loads and the maximum instantaneous power of all loads can be determined respectively by using the start sequence of the long-term power of each load and the maximum instantaneous power of each load displayed by the visualization tool. As a preferred implementation, the visualization tool can be set as a table, a line graph, or a scatter plot.

[0099] See also Figure 8 , Figure 8 This is a schematic diagram showing the long-term power of each sub-item load and the maximum instantaneous power of each sub-item load in a table. Figure 8 In the above, situation 1 means that the long-term power of each load is started at the same time, and the instantaneous power of each load is also started at the same time; situation 3 means that the long-term power of each load is started at the same time, and the instantaneous power of each load is not started at the same time; situation 4 means that the long-term power of each load is zero, and the instantaneous power of each load is not started at the same time; situation 5 means that the long-term power of each load is not started at the same time, and the instantaneous power of each load is not started at the same time; there is a special situation in situation 1, which can be called situation 2, that is, the long-term power of each load is zero, and the instantaneous power of each load is started at the same time. From Figure 8In the table shown, in addition to being able to clearly and intuitively view the long-term power and maximum instantaneous power of the sub-loads such as the high-voltage box BMS (Battery Management System) power system, fire power supply system, switching power supply system, cabinet control power supply and switch, you can also view the relevant operating parameters of each sub-load such as the high-voltage box BMS power system, fire power supply system, switching power supply system, cabinet control power supply and each internal device in the switch, such as: setting quantity, long-term power and maximum instantaneous power, etc.

[0100] Obviously, through the technical solution provided in this embodiment, the staff can determine the maximum long-term power of all loads and the maximum instantaneous power of all loads more intuitively and accurately.

[0101] Based on the above embodiment, this embodiment further illustrates and optimizes the technical solution. As a preferred implementation, the above step: selecting the long-term power characteristics and overload power characteristics of the target UPS according to the maximum long-term power of all loads and the maximum instantaneous power of all loads to obtain the selected UPS includes:

[0102] The target UPS model is selected according to the maximum long-term power of all loads and the preset margin, and the selection result of the target UPS is corrected according to the maximum instantaneous power of all loads to obtain the selected UPS.

[0103] In this embodiment, when selecting the model of the target UPS, the model of the target UPS can be first selected based on the maximum long-term power and preset margin of all loads, and the selection result of the target UPS can be corrected based on the maximum instantaneous power of all loads, thereby obtaining the selected UPS.

[0104] Here Figure 8 Taking the load shown in the figure as an example, the selection process of the target UPS is described in detail. Figure 8 It can be seen that the maximum long-term power of all loads is 809.6W, and the maximum instantaneous power of all loads is 2209.6W. If the preset margin is set to 1.3, the target UPS can be selected according to the 1.3 times margin of the maximum long-term power of all loads 809.6W. At this time, the maximum long-term power of the target UPS is recommended to use a UPS higher than 1052.5W to power each load. In this case, the target UPS can be set to 2kVA / 1.6kW and above.

[0105] In addition to meeting the power requirements of long-term load operation, the UPS can also meet the short-term overload requirements. The target UPS also needs to be able to support a maximum instantaneous power load of 2209.6W. Therefore, the model of the target UPS can be selected based on the overload capacity of the target UPS.

[0106] Assume that a UPS can work for 10 minutes when overloaded by 115% to 130%, can work for 30 seconds when overloaded by 130% to 150%, and can work for 200ms when overloaded by more than 150%. In this case, the UPS can be selected based on the UPS overload of 150% and the overload working time of 200ms. At this time, the maximum instantaneous power of the target UPS should be higher than 1473W. In this case, UPS of 2kVA / 1.6kW and above just meet this condition, so the target UPS can be set to UPS of 2kVA / 1.6kW and above.

[0107] Obviously, through the technical solution provided by this embodiment, the model of the target UPS can be accurately determined.

[0108] Based on the above embodiment, this embodiment further illustrates and optimizes the technical solution. As a preferred implementation method, the above step of using the selected UPS to supply power to each load includes:

[0109] The target model is used to select the model of the battery cell in the selected UPS to obtain the selected battery cell, and the selected battery cell is used to power each load;

[0110] The expression of the target model is:

[0111] P*t=C*U*n;

[0112] Where P is the maximum long-term power of all loads, t is the backup time, C is the capacity of the battery in the selected UPS, U is the output voltage of the battery in the selected UPS, and n is the number of battery cells in the selected UPS.

[0113] In this embodiment, after the target UPS model is selected and the selected UPS is obtained, the model of the battery cell in the selected UPS can be selected according to the target model to obtain the selected battery cell, and the selected battery cell is used to power each load.

[0114] Specifically, based on the target model, when the maximum long-term power of all loads is 809.6W, if the DC power supply voltage of the selected UPS is 72V, then 6 battery cells with an output voltage of 12V need to be set in the selected UPS.

[0115] If the UPS needs to have a backup power of 0.5 hours after selection, the capacity of the selected battery should be higher than 5.6Ah. Considering that there is a certain margin, the selection is made according to 1.3 times the margin, so the capacity of the battery should be higher than 7.3Ah;

[0116] If the UPS needs to be backed up for 1 hour after selection, the capacity of the battery should be higher than 11.2Ah. Considering that there is a certain margin, the selection is made according to 1.3 times the margin, so the capacity of the battery should be higher than 14.6Ah;

[0117] If the UPS needs to have a 2-hour backup power supply after selection, the capacity of the battery cell should be higher than 22.4Ah. Considering that there is a certain margin, the selection is made according to 1.3 times the margin, so the capacity of the battery cell should be higher than 29.2Ah.

[0118] Obviously, through the technical solution provided in this embodiment, the model of the battery cell in the selected UPS can be accurately determined.
