[0002] UPS (Uninterruptible Power Supply) is an energy supply device used to provide uninterrupted power supply to power electronic equipment. Modern UPS systems usually use multiple UPS units in parallel to ensure the reliability of power supply. Since the load is constantly changing, when the load is small, if all UPS units are put into use, the loss of UPS operation will cause a lot of energy waste. Therefore, when the load is too low, some UPS units will be controlled to sleep; when the load becomes larger, the UPS units will be awakened.

[0003] In the prior art, when the UPS is in sleep mode, the power of the UPS system is usually detected every preset time to wake up the UPS unit. If the load suddenly increases, the response speed of the above wake-up method is too slow, which will cause the inverter waveform of the UPS unit to be distorted, affecting the stability of the UPS system.

[0015] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present invention. However, it should be clear to those skilled in the art that the present invention may be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present invention.

[0016] In order to make the purpose, technical solutions and advantages of the present invention more clear, specific embodiments will be described below in conjunction with the accompanying drawings.

[0017] See also Figure 1, which shows a flowchart of the implementation of the sleep control method of the UPS system provided by an embodiment of the present invention, wherein the UPS system includes at least one UPS unit; the details are as follows:

[0018] The sleep control method of the UPS system includes:

[0019] S101: Acquire multiple output currents and multiple output voltages of a UPS system sampled within a preset time period before a current moment;

[0020] S102: determining a load rate of the UPS system at a current moment according to the multiple output currents and the multiple output voltages;

[0021] S103: If the load rate of the UPS system at the current moment is greater than a first preset value, wake up some or all of the UPS units in the UPS system that are in a dormant state.

[0022] The embodiment of the present invention is based on the sliding window principle. At each moment, multiple output currents and multiple output voltages of the UPS system sampled within a preset time period before the current moment are obtained. For example, at 10ms, multiple output currents and multiple output voltages collected within 8 to 9ms are obtained, at 11ms, multiple output currents and multiple output voltages collected within 9 to 10ms are obtained, at 12ms, multiple output voltages and multiple output currents collected within 10 to 11ms are obtained, and so on, to form a sliding window. In the embodiment of the present invention, steps S101 to S103 are repeatedly executed at each moment, and the load rate is updated in real time according to the output voltage and output current. The load rate can be monitored in real time. When it is found that the load rate is large, some or all UPS units in the dormant state are awakened in time to prevent overload. The response speed is fast, and the stability of the UPS system is effectively improved.

[0023] At the same time, by using multiple output voltages and multiple output currents within a preset time period to update the load rate, no malfunction will occur due to a single sampling error, effectively improving the accuracy of the control method.

[0024] In a possible implementation, S102 may include:

[0025] S1021: Determine a target output current of the UPS system according to the multiple output currents;

[0026] S1022: Determine a target output voltage of the UPS system according to the multiple output voltages;

[0027] S1023: Multiply the target output current by the target output voltage to obtain the actual output power of the UPS system

[0028] S1024: Divide the actual output power of the UPS system by the rated output power of the current UPS system to obtain the load rate of the UPS system at the current moment.

[0029] The load rate is the ratio of the actual output power of the device to the rated output power. In the embodiment of the present invention, the actual output power of the UPS system is determined according to the sliding window voltage and current, and then the load rate of the UPS system is calculated.

[0030] In a possible implementation manner, before S1024, S102 may further include:

[0031] S1025: Obtain the number of UPS units in the current UPS system that are in working state;

[0032] S1026: Multiply the number of UPS units in the current UPS system that are in working state by the rated output power of a single UPS unit to obtain the rated output power of the current UPS system.

[0033] Normally, the rated output power of each UPS unit is the same. The UPS units are connected in parallel to form a UPS system. The rated output power can be obtained by multiplying the number of UPS units in operation by the rated output power of a single UPS unit.

[0034] In a possible implementation, S1021 may include:

[0035] 1. Determine the average of multiple output currents to obtain the target output current;

[0036] S1022 may include:

[0037] 1. Determine the average of multiple output voltages to obtain the target output voltage.

[0038] In the embodiment of the present invention, the average value of multiple output currents can be used as the target output current, and the average value of multiple output voltages can be used as the target output voltage, so as to calculate and obtain the actual output power of the UPS system.

[0039] In a possible implementation, S103 may include:

[0040] S1031: Obtain the number of UPS units in the current UPS system that are in a dormant state;

[0041] S1032: If the number of UPS units in the current UPS system that are in a dormant state is less than a preset number, all the UPS units in a dormant state are awakened;

[0042] S1033: If the number of UPS units in the current UPS system that are in a dormant state is not less than a preset number, then wake up a preset number of UPS units that are in a dormant state.

[0043] In the embodiment of the present invention, when it is detected that the load rate of the UPS is greater than a first preset value, for example, the first preset value may be 0.9, that is, when the load rate of the UPS is already very high, the UPS units in the dormant state are awakened. Since the UPS is not overloaded at this time and the load change cannot be predicted, a preset number of UPS units may be awakened each time.

[0044] The preset number may be 2. Specifically, the value of the preset number may be set according to actual application conditions.

[0045] For example, when the load rate is greater than 0.9, two UPS units are awakened; at the next moment, the load rate is updated according to the sliding window voltage and current. If the load rate is still greater than 0.9, two more UPS units are awakened, and so on. This ensures that the number of awakened UPS units in the UPS system remains within a reasonable range, which can ensure power supply to the load without causing energy waste.

[0046] In a further implementation manner, the number of UPS units to be awakened may be determined according to the load rate.

[0047] For example, when the load is large, a larger number of UPS units are awakened; when the load rate is relatively small, a smaller number of UPS units are awakened, and the number of awakened units is determined according to the load rate. The details are not repeated here.

[0048] In a possible implementation, the above method may further include:

[0049] S104: Obtaining a change in the load rate of the UPS system;

[0050] S105: Adjusting the preset duration according to the change in the load factor of the UPS system.

[0051] The setting of the sliding window size (i.e., the preset duration) will have a certain impact on the monitoring of the load rate. For example, when the load rate changes greatly, setting the preset duration too long may cause the calculated load rate to be inaccurate. Therefore, the embodiment of the present invention can dynamically adjust the sliding window size (preset duration) according to the change in the load rate, thereby improving the accuracy of the control.

[0052] In a possible implementation, S105 may:

[0053] S1051: If the absolute value of the load rate change is greater than the preset change, setting the preset time length to a first preset time length;

[0054] S1051: If the absolute value of the change in the load rate is not greater than the preset change, setting the preset time length to a second preset time length;

[0055] Among them, the first preset time length is shorter than the second preset time length.

[0056] Based on the above, when the load rate changes greatly, the preset time length is set to a smaller first preset time length; when the load amount changes less, the preset time length is set to a larger second preset time length. The preset time length is dynamically adjusted to improve the control accuracy.

[0057] Furthermore, the preset duration may be dynamically adjusted according to the change in load, and is not limited to two values ​​(the first preset duration and the second preset duration).

[0058] In a possible implementation, the above method may further include:

[0059] S106: if the load rate of the UPS system at the current moment is not greater than a second preset value, determining the number of dormant UPS units according to the load rate of the UPS system at the current moment; wherein the second preset value is less than the first preset value;

[0060] S107: Control a corresponding number of UPS units in the current UPS system that are in working state to enter a dormant state.

[0061] When the load rate of the UPS decreases, similarly, the corresponding number of UPS units are controlled to enter the sleep state according to the load rate, so as to control the number of UPS units in the awake state within a reasonable range to avoid resource waste. Among them, the second preset value can be smaller than the first preset value, and the two values ​​are different and have a certain difference, so as to ensure that the UPS can work stably and will not wake up or sleep frequently due to errors.

[0062] In a possible implementation manner, the first preset value may range from 0.85 to 0.95.

[0063] In a possible implementation manner, the second preset value may range from 0.75 to 0.85.

[0064] In a possible implementation, S106 may include:

[0065] S1061: Determine the target number of UPS units in working state according to the load rate of the UPS system at the current moment;

[0066] S1062: Subtract the target number from the number of UPS units in the current UPS system that are in working state to obtain the number of dormant UPS units.

[0067] Specifically, the target number m xThe calculation formula can be:

[0068]

[0069] Among them, m t is the number of UPS units currently in operation, k t is the load rate at the current moment, and k0 is the optimal load rate.

[0070] It should be understood that the order of execution of the steps in the above embodiment does not necessarily mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiment of the present invention.
