DETAILED DESCRIPTION

[0012] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0013] In the description of the present application, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the feature. In the description of the present application, "plurality" means two or more, unless otherwise clearly and specifically defined.

[0014] In this application, the word "exemplary" is used to mean "used as an example, illustration or description". Any embodiment described as "exemplary" in this application is not necessarily to be construed as being more preferred or advantageous than other embodiments. At the same time, it is to be understood that in the specific implementation of this application, when user information, user data and other related data are involved, when the above embodiments of this application are applied to specific products or technologies, user permission or consent is required, and the collection, use and processing of relevant data shall comply with relevant laws, regulations and standards of relevant countries and regions.

[0015] In order to enable any person skilled in the art to implement and use the present application, the following description is provided. In the following description, details are listed for the purpose of explanation. It should be understood that those of ordinary skill in the art will recognize that the present application can be implemented without using these specific details. In other examples, known structures and processes will not be elaborated in detail to avoid unnecessary details that make the description of the present application obscure. Therefore, the present application is not intended to be limited to the embodiments shown, but is consistent with the widest range of principles and features disclosed in the present application.

[0016] The power distribution unit is a power distribution device used to distribute one input power to multiple outputs. It is widely used in scenarios that require efficient power management, such as telecommunications centers, communication base stations, data centers, and mining machines. These scenarios usually have the characteristics of large input current, multiple output circuits, and relatively small output current. The PDU device ensures that various types of equipment can operate stably by reasonably distributing power, and effectively prevents equipment damage or system failures caused by excessive power load.

[0017] However, existing PDU devices have significant limitations in design and function. First, existing PDU devices also have obvious deficiencies in the design of output interfaces. The output interface of the PDU is usually designed as a single-phase interface or a three-phase interface, but the two are often not compatible. If flexible switching between single-phase and three-phase devices is required, existing devices are not compatible with single-phase and three-phase loads at the same time, which means that when three-phase current load balancing is required, users must configure three different types of interfaces to output phase A, phase B, and phase C respectively. This design greatly increases the complexity of operation, reduces the flexibility of the system, and makes it difficult to meet the higher requirements of modern power systems for load balancing and interface compatibility. In actual applications, this design deficiency may lead to difficulties in equipment configuration and maintenance, and the inability to quickly adapt to changes in power demand, which in turn affects the stability and efficiency of the overall system.

[0018] Secondly, traditional PDU devices usually rely on only one traditional circuit breaker to provide overload protection and local segmentation functions for the output current. Although this design can prevent failures caused by overload to a certain extent, it lacks more comprehensive power protection functions such as leakage protection, overvoltage protection, undervoltage protection, and loss of voltage protection. The lack of these protection functions makes it impossible for the PDU to provide sufficient safety protection for connected devices in complex power environments, increasing the risk of equipment damage and system downtime. In addition, most existing PDU devices do not support remote segmentation control, which means that operators cannot remotely manage the power supply of the PDU, limiting the application of PDU in modern intelligent power management, especially in scenarios that require timely response and adjustment of power distribution.

[0019] The output unit of the load balancing system of the present application is provided with a highly compatible interface module, which includes a single-phase interface and a three-phase interface. The flexible access of single-phase equipment and three-phase equipment can be realized without separately configuring multiple power distribution units, thereby greatly simplifying the process of equipment configuration and load balancing, and reducing the difficulty of system and equipment maintenance. In addition, the load balancing system can obtain three-phase current through the metering module, and perform load balancing functions on single-phase equipment and three-phase equipment at the same time. In the process of load balancing detection, the load conditions of different types of equipment can be considered more comprehensively, thereby improving the accuracy of load balancing detection and adjustment of equipment. In addition, the load balancing system of the present application not only retains the overload protection and local segmentation functions of traditional circuit breakers, but also adds key functions such as leakage protection, overvoltage protection, undervoltage protection and loss of voltage protection, so as to effectively prevent equipment failure or damage caused by power anomalies, significantly improve the safety and reliability of the system, and ensure the stable operation of the equipment in various complex environments.

[0020] The present application provides a load balancing system, method, computer device and readable storage medium, which are described in detail below.

[0021] like Figure 1 As shown, Figure 1 : is a structural diagram of a load balancing system provided in an embodiment of the present application. The load balancing system may include an output unit and a host unit. The output unit may include a connected metering module and an interface module, wherein: The interface module can be used to connect the device to the load balancing system. Among them, the device can be a device that uses a single-phase power supply and a three-phase power supply. In some embodiments, the interface module of the present application can be designed as an interface compatible with single-phase devices and three-phase devices, so that whether it is a device that requires a single-phase power supply (such as common household appliances) or a device that requires a three-phase power supply (such as industrial equipment), it can be safely connected to the system through the interface module. The different terminals in the interface module are responsible for connecting the A phase, B phase, C phase, the neutral line (N phase) and the protective ground line (PE line), respectively, to ensure that the device can be correctly connected to the load balancing system of the present application.

[0022] The interface module allows devices to be connected to different phases, and through the built-in current monitoring and control function, it can monitor the current load of each phase in real time. This design enables the interface module to flexibly allocate devices to the appropriate phase according to the real-time load of the system, prevent overloading of a phase, and ensure balanced operation of the system.

[0023] In some embodiments, the output unit may include a first output unit, a second output unit, a third output unit and a three-phase output unit with different interface modules; the first output unit, the second output unit and the third output unit are connected in sequence to form a three-phase output unit.

[0024] like Figure 2 As shown, the first output unit, the second output unit and the third output unit can be collectively referred to as one-output-one unit, indicating that this type of output unit has only one input and outputs power through one output interface. Specifically, the first output unit can be configured with an A-type interface module for outputting a power signal based on phase A. The second output unit can be configured with an A-type interface module for outputting a power signal based on phase B. The third output unit can be configured with an A-type interface module for outputting a power signal based on phase C.

[0025] like Figure 3As shown, the three-phase output unit can be one-output three-unit, which means that this type of output unit has only one input, but can output power through three output interfaces at the same time. Specifically, the first output unit, the second output unit, and the third output unit can be connected in sequence to form a complete three-phase output unit. Through this combination, each output unit processes the power output of one phase respectively, so that balanced output of three-phase power can be achieved physically and functionally.

[0026] Through the structure of the above output units, the load balancing system can not only provide flexible single-phase or three-phase power output, but also achieve balanced distribution of loads in each phase through modular combination, thereby improving the adaptability and reliability of the system.

[0027] In some embodiments, the interface module may include: A first interface provided in the first output unit, the first interface being used to connect the device to the first phase current; A second interface provided in the second output unit, the second interface being used to connect the device to the second phase current; A third interface is provided on the third output unit, and the third interface is used to connect the device to the third phase current; The first interface, the second interface and the third interface are connected in sequence to form a three-phase interface of a three-phase output unit.

[0028] Among them, the first phase is phase A, the second phase is phase B, and the third phase is phase C. It can be understood that the devices connected through the first interface will receive the A phase current for their normal operation, the devices connected through the second interface will receive the B phase current, and the devices will use the C phase current after being connected through the third interface. Accordingly, the three-phase output unit can provide A phase, B phase and C phase current at the same time to meet the needs of devices that require three-phase power.

[0029] In some embodiments, the device can access a specific phase current according to actual needs. If the device needs single-phase power, it can choose to connect to any interface module (such as the first interface, the second interface, or the third interface); if three-phase power is required, it can access A, B, and C three-phase currents through a combination of three interface modules.

[0030] By connecting different devices to currents of different phases, better load balancing can be achieved, preventing current overload in one phase. This also ensures balanced distribution of three-phase power and optimizes the operating efficiency of the power system.

[0031] In some embodiments, it can be easily expanded or adjusted according to actual needs. Specifically, more output units can be added to support more device access, or the connection mode of the interface module can be reconfigured to meet special power requirements. For example, the number of output units can be expanded according to the connection order of the first output unit, the second output unit, and the third output unit. For example, there are 6 output units in total, and the 1st to 3rd output units are the first output unit, the second output unit, and the third output unit, respectively. Similarly, the 4th to 6th output units are the first output unit, the second output unit, and the third output unit, respectively. For another example, the output units can be all set to three-phase output units, or the three-phase output units can be mixed with the first, second, and third output units, which is not limited to this embodiment of the present application.

[0032] Through the above structure, not only can the flexibility and scalability of the system be improved, but it can also effectively support load balancing and system optimization, ensuring the efficiency and stability of power distribution.

[0033] In some embodiments, the first interface, the second interface, and the third interface each include a first terminal for connecting to the first phase current, a second terminal for connecting to the second phase current, a third terminal for connecting to the third phase current, a fourth terminal for connecting to the neutral line, and a fifth terminal for connecting to the protective grounding line; The terminal arrangement structure of the first interface is that the first terminal, the second terminal, the third terminal, the fourth terminal and the fifth terminal are connected in sequence; The terminal arrangement structure of the second interface is that the second terminal, the third terminal, the first terminal, the fourth terminal and the fifth terminal are connected in sequence; The terminal arrangement structure of the third interface is that the third terminal, the first terminal, the second terminal, the fourth terminal and the fifth terminal are connected in sequence.

[0034] like Figure 4 As shown, the first interface, the second interface and the third interface have different terminal arrangement structures. The first terminal is used to connect the first phase current (i.e., A phase current), the second terminal is used to connect the second phase current (i.e., B phase current), the third terminal is used to connect the third phase current (i.e., C phase current), the fourth terminal is used to connect the neutral line (N line), and the fifth terminal is used to connect the protective grounding line (PE line).

[0035] In the first interface, the terminal arrangement structure is in the order of phase A, phase B, phase C, neutral line and protective grounding line. The device that can be connected through the first interface will be connected to the first terminal, the fourth terminal and the fifth terminal in sequence, ensuring that the device can obtain power mainly of phase A current.

[0036] In the second interface, the terminals are arranged in the order of phase B, phase C, phase A, neutral line, and protective grounding line. The device that can be connected through the second interface will be connected to the second terminal, the fourth terminal, and the fifth terminal in sequence to ensure that the device can obtain power mainly based on the phase B current.

[0037] In the third interface, the terminals are arranged in the order of phase C, phase A, phase B, neutral line and protective grounding line. The devices that can be connected through the third interface will be connected to the third terminal, the fourth terminal and the fifth terminal in sequence to ensure that the devices can obtain power mainly based on the phase C current.

[0038] In some embodiments, the device may be connected to the first terminal, the second terminal, the third terminal, the fourth terminal, and the fifth terminal in sequence, ensuring that the device can obtain power of three-phase current.

[0039] Through this terminal arrangement structure design, each interface module can connect the device to different phase currents, thereby meeting the requirements of different devices for power phases, which is conducive to achieving load balancing in the three-phase power system.

[0040] Since the terminal arrangement order of each interface module is different, the system can ensure fast device access and more balanced distribution of three-phase current by reasonably configuring the device access method. Specifically, the device can preferentially access the first terminal of each interface. For example, when the device is connected to the first interface, it can quickly obtain the A-phase current, thereby improving the overall operation efficiency of the system.

[0041] The arrangement of the neutral line (the fourth terminal) and the protective grounding line (the fifth terminal) of each interface is fixed in all interface modules, ensuring that the equipment can be correctly connected to the neutral line and the grounding line under any circumstances, thus ensuring the safety of the power system and the reliability of the equipment.

[0042] In some embodiments, the output unit may further include a circuit breaker, a male connector, and a female connector connected in sequence, wherein: The circuit breaker is used to protect the load balancing system from overload. The input side of the circuit breaker is connected to the busbar of the load balancing system, and the output side is connected to the metering module. The male plug is used to cooperate with the female plug to transmit current; The female plug is used to cooperate with the male plug to transmit current.

[0043] Among them, the circuit breaker is an important part of the output unit, and its main function is to provide overload protection for the load balancing system. In the power system, when the current exceeds the preset safety threshold, the circuit breaker will automatically cut off the circuit to prevent excessive current from causing damage to the equipment or system. Figure 2 and Figure 3As shown, the first output unit, the second output unit and the third output unit are each provided with a circuit breaker, and the three-phase output unit is provided with a circuit breaker.

[0044] The input side of the circuit breaker is connected to the busbar of the load balancing system, and the power input is obtained from the busbar. The output side of the circuit breaker is connected to the metering module, so that the power after the circuit breaker protection can be transmitted to the metering module, and then the metering module monitors and adjusts the current distribution. By setting up the circuit breaker, the system can respond to the current overload in time, prevent equipment damage or power failure caused by overload, and ensure the safe and stable operation of the entire load balancing system.

[0045] The male plug is the connector part used for current transmission, with protruding pins or metal pins that can be inserted into the corresponding female plug. The male plug is used to transmit current from the output end of the circuit breaker to the next system or equipment part, and is responsible for cooperating with the female plug to form a stable electrical connection.

[0046] The female plug is the mating connector part of the male plug, with holes or grooves for receiving the pins or pins of the male plug. The female plug cooperates with the male plug to receive the current transmitted from the male plug and transmit it to the next circuit or device to ensure the smooth transmission of current and the safety of connection.

[0047] In the load balancing system, the combination of the circuit breaker with the male and female plugs not only provides overload protection, but also ensures the safe transmission of current. This is especially important for power systems that require frequent maintenance, expansion or adjustment. Through the design of male and female plugs, equipment maintenance and upgrades become easier, reducing system downtime and improving operational safety.

[0048] In some embodiments, the load balancing system may further include a metering module for determining the load type of each device and the phase current value of each device, and determining the load detection result according to the load type and the phase current value of each device.

[0049] The load type of the device may include single-phase load, three-phase load or no load, etc. By monitoring the current consumption of each device, the metering module can identify which load type the device currently belongs to, thereby providing basic data for subsequent power distribution and load balancing.

[0050] In some embodiments, the metering module can also measure the phase current value of each device, that is, the current magnitude of phase A, phase B, and phase C. By monitoring the current of each phase in real time, the metering module can collect power consumption data of the device on different phases to determine the load balance status of the power system.

[0051] In some embodiments, if the metering module detects that a device has a larger current consumption on phase A and phase B respectively, and a smaller current on phase C, the system can determine that the load of the device is unbalanced and make corresponding adjustment suggestions.

[0052] Based on the analysis of load type and phase current value, the metering module can obtain load detection results, which will display the specific load conditions of each device, including whether there is current imbalance, whether a phase is overloaded, whether there is any device in a no-load state, etc. The detection results can be fed back to the main control part of the load balancing system so that the system can make corresponding adjustments according to the actual situation, such as reallocating the load, switching the phase connection of the device, or issuing an alarm to prompt the operation and maintenance personnel to take measures.

[0053] In summary, by monitoring and analyzing the load type and phase current value of each device, the metering module can generate detailed load detection results, which provides an important basis for the intelligent adjustment of the load balancing system, ensuring that the system can respond to load changes in a timely manner and maintain the stability and efficient operation of the power system.

[0054] In some embodiments, the metering module may include a metering module input line and a metering module output line, wherein the metering module input line is connected to the circuit breaker and connected to the male plug.

[0055] Among them, the metering module incoming line refers to the input terminal where the current enters the metering module, which is responsible for introducing the current from other parts of the system into the metering module for measurement and monitoring by the metering module. The metering module incoming line is connected to the output terminal of the circuit breaker. The current after the circuit breaker protection will enter the metering module through the metering module incoming line. In this way, the metering module can monitor the current protected by the circuit breaker to ensure the safety and accuracy of the measurement data. The metering module incoming line is also connected to the plug-in male connector, and the current needs to be connected through the plug-in male connector before entering the metering module. As an intermediate connector, the plug-in male connector can be easily connected to other modules in a plug-in manner, simplifying the installation and maintenance process of the system.

[0056] Among them, the metering module output line refers to the terminal where the current is output from the metering module. The current monitored and processed by the metering module will be transmitted to the next system component or device through the output line. The metering module output line transmits the current processed by the metering module to other parts of the load balancing system, such as the output unit or device access point.

[0057] Through the above structure, the metering module is connected to the circuit breaker and the male plug through the design of the incoming and outgoing lines, forming a safe, flexible and efficient power monitoring system. The incoming line of the metering module is connected to the circuit breaker to ensure the safety of the input current, and at the same time connected to the male plug, providing a convenient modular management method. After being monitored and processed by the metering module, the current continues to be transmitted to other parts of the system through the outgoing line of the metering module, completing the precise monitoring of the equipment load and power distribution, which not only enhances the safety of the system, but also improves the flexibility of operation and the convenience of maintenance.

[0058] In some embodiments, the metering module can also collect voltage values ​​and leakage current values, and perform alarm and protection tripping functions according to the preset voltage undervoltage threshold, overvoltage threshold, voltage loss condition (for example, if only two phases have voltage, it is judged as voltage loss), and overcurrent threshold. Leakage has the highest priority. As long as leakage is detected, the relay in the metering module is directly controlled to trip. When overvoltage, undervoltage, voltage loss, and overcurrent occur, the status can be reported to the host unit. The host unit can control the relay status of each metering module through communication according to the preset protection type, thereby realizing the alarm and protection function of the PDU power distribution unit.

[0059] In some embodiments, the load balancing system may further include a host unit, which is used to generate a load adjustment instruction for each device according to the load detection result, and perform load balancing adjustment on each device.

[0060] The host unit receives and analyzes the load detection results from the metering module. The metering module communicates with the host through the RS485 bus. The metering module can monitor the load type and phase current value of each device and transmit these data to the host unit. For example, the load detection results may include the current consumption of each device, the phase current distribution, and whether there is load imbalance or abnormality.

[0061] In some embodiments, the load adjustment instructions generated by the host unit can be sent to each output unit in the system or directly to the relevant device. After receiving the instructions, the output unit or device can automatically adjust the current access mode or phase connection. The adjustment method may include switching the phase of the device, adjusting the current distribution ratio, or cutting off the power supply of certain devices when necessary to prevent the system from being overloaded or unbalanced.

[0062] The host unit has the ability to adjust in real time and can continuously optimize the load distribution according to the changes in the load detection results. When the load changes, the host unit will continuously update the instructions to ensure that the system's load distribution is always balanced. After performing the adjustment, the host unit will also monitor the system's feedback to check whether the load adjustment has achieved the expected effect and further optimize the instructions if necessary.

[0063] The host unit generates load adjustment instructions for each device by analyzing the load detection results provided by the metering module, and intelligently adjusts the load of the device. The introduction of the host unit enables the load balancing system to respond to load changes in real time, optimize power distribution, and ensure the safe, stable and efficient operation of the system. It not only reduces the need for manual intervention, but also significantly improves the intelligent management level of the power system.

[0064] In some embodiments, the host can also display the power parameters and energy parameters of each metering module. According to the load type reported by the metering module, display the relevant type of data. If it is a single-phase type device, display the voltage, current, power and energy. If it is a three-phase data, display the three-phase voltage, three-phase current, three-phase power and energy. If the device is a no-load type, the display interface shows that the data is empty. If the load is abnormal, report the abnormal load to the system and indicate the load abnormality on the host.

[0065] like Figure 5 As shown, Figure 5 This is a flow chart of a load balancing method in an embodiment of the present application. The load balancing method may include the following steps 101 to 104.

[0066] Step 101: Obtain the phase current value of each device connected to the load balancing system.

[0067] In some embodiments, when a device is connected to a load balancing system, it can be connected to different phases of the system through a designated output unit, such as phase A, phase B, or phase C. Each device is connected to only a single phase, or multiple phases can be connected at the same time, such as a three-phase device.

[0068] The metering module is installed at the back end of each output unit and connected to the access point of each device. The built-in current sensor monitors the phase current of each device in real time. When the device is connected to the system and starts to consume power, the metering module can detect the current flow of the device on each phase and record the current values ​​of phase A, phase B, and phase C.

[0069] The metering module can continuously collect the current data of the equipment and generate information including the phase current value. Regardless of whether the equipment is a single-phase load or a three-phase load, the metering module can obtain the current value of each phase separately and transmit it to the host unit of the load balancing system through the communication line within the system for subsequent analysis and adjustment.

[0070] Step 102: Determine the load type of each device according to the phase current value of each device.

[0071] In some embodiments, the load type of each device can be determined based on the phase current value of each device, and the number of devices of each load type can be counted, so as to facilitate subsequent load balancing operations on business scenarios based on the above information.

[0072] In some embodiments, the load type of a device may be determined by: First, detect whether the device has only one of the first phase current, the second phase current and the third phase current. If the device has only one of the first phase current, the second phase current and the third phase current, determine that the load type of the device is a single-phase load; Next, if the device does not have only one of the first phase current, the second phase current and the third phase current, it is detected whether the device has all of the first phase current, the second phase current and the third phase current; Then, if the device has all the first-phase current, the second-phase current and the third-phase current, it is determined that the load type of the device is a three-phase load; Finally, if the device does not have any of the first phase current, the second phase current, and the third phase current, it is determined that the load type of the device is no load or abnormal load.

[0073] In some embodiments, it is possible to detect whether the device is connected to only one of the three-phase currents, that is, to detect whether the device has only one of the first phase current (A phase current), the second phase current (B phase current) or the third phase current (C phase current). If the current measurement result of the device shows that there is current only in one phase of the A phase, the B phase or the C phase, and there is no current in the other two phases, it can be determined that the device is a single-phase load.

[0074] In some embodiments, if the device is not a single-phase load, that is, it does not use only one of phase A, phase B, or phase C, it can be further detected whether the device has all three phases of current at the same time. In other words, the system checks whether the device has current passing through phases A, B, and C. If the current measurement result of the device shows that there is current on phases A, B, and C, it means that the device uses three-phase power.

[0075] If the device is not identified as a single-phase or three-phase load in both the initial detection and the further detection, the system will check whether there is no current passing through the device at all. In other words, the system will detect whether the device has no current at all on phases A, B, and C. If no current is detected on all three phases, the device may be in a no-load state, that is, the device is not connected to the power system or is not operating. In this case, the system determines the load type of the device as no load, which means that the device is not currently operating or connected to power. If the device should be connected to power but still has no current, there may be a connection problem or device failure, which the system can mark as an abnormal load to trigger an alarm or further inspection.

[0076] Through the above methods, the system can accurately identify the load type of each device, so as to take corresponding measures in load balancing and power management. Whether it is single-phase load, three-phase load, or no load or abnormal load, the system can effectively adjust and control based on this information to ensure the stability and efficient operation of the power system.

[0077] For detailed steps, please refer to Figure 6 ,like Figure 6 As shown, determining the load type of the device may include the following steps 201-206: Step 201: Calculate the phase current value of each phase of the device.

[0078] Step 202 , determining whether the device has a first phase current, if so, determining that the load type of the device is a single-phase load connected to the first phase, if not, proceeding to step 203 .

[0079] Step 203 , determine whether the device has a second phase current, if so, determine that the load type of the device is a single-phase load connected to the second phase, if not, proceed to step 204 .

[0080] Step 204 , determine whether the device has a third-phase current. If so, determine that the load type of the device is a single-phase load connected to the third phase. If not, proceed to step 205 .

[0081] Step 205 , determine whether the device has three-phase current. If so, determine that the load type of the device is a three-phase load connected to the first phase, the second phase and the third phase. If not, proceed to step 206 .

[0082] Step 206 , determining whether the device does not have three-phase current, if so, determining the load type of the device is no load, otherwise, determining the load type of the device is abnormal load.

[0083] It can be understood that in order to improve the standardization of load type detection, the device can be detected in the order of the first phase current, the second phase current and the third phase current, and first determine whether the device is a single-phase load. If the detection device has more than one current, it can be further detected whether the device has three phases of current and whether it is a three-phase load. If the device has neither only a single-phase current nor three-phase current at the same time, it is then determined whether the load is a no-load or abnormal load type.

[0084] Step 103: Determine a load detection result according to the load type and phase current value of each of the devices.

[0085] In some embodiments, after determining the load type and phase current value of each device, the current value generated by each device in the corresponding phase can be further determined. For example, if device 1 is a single-phase load connected to the first phase and the phase current value generated is 10A, then when subsequently calculating the total current generated by each phase in the system, the 10A current generated by the device can be counted in the total current of the first phase.

[0086] In some embodiments, the number of devices of each load type may be counted according to the load type of each device, for example, 10 single-phase loads, 5 three-phase loads, etc. In this way, each device may be reasonably allocated to be evenly connected to the three phases to achieve load balancing.

[0087] In some embodiments, the load detection result may be determined by: First, obtain a first number of first interfaces corresponding to the first phase current, a second number of second interfaces corresponding to the second phase current, and a third number of third interfaces corresponding to the third phase current of each device; Secondly, obtaining the first-phase total current of the sum of the first-phase currents generated by each device, the second-phase total current of the sum of the second-phase currents, and the third-phase total current of the sum of the third-phase currents; Then, determining a first load detection result according to the first quantity, the second quantity and the third quantity; Next, determining a second load detection result according to the first phase total current, the second phase total current and the third phase total current; Finally, a load detection result is determined according to the first load detection result and the second load detection result.

[0088] It can be understood that if the number of devices in each phase is close or equal, the system can determine that the device distribution is relatively balanced. If the number of devices in a phase is significantly more than that in other phases, the system can determine that the device load in that phase is heavier. Correspondingly, if the total current of each phase is close or equal, the system can determine that the current distribution is balanced, even if there is a difference in the number of devices. If the total current of a phase is significantly greater than that of other phases, the system can determine that the load in that phase is unbalanced and there is a risk of overload.

[0089] In some embodiments, if both the first load detection result and the second load detection result show that the load is balanced, the system ultimately determines that the load is balanced. If one or both of them show that the load is unbalanced, the system determines that there is a load imbalance and may generate a load adjustment suggestion or warning. By combining the detection results of these two aspects, the system can more accurately reflect the load status and take corresponding measures to ensure system stability.

[0090] In some embodiments, the first load detection result may be determined by: First, if the difference between any two of the first quantity, the second quantity and the third quantity is greater than the quantity threshold, the first load detection result is determined to be abnormal; Next, if the difference between any two of the first number, the second number and the third number is less than or equal to the number threshold, it is determined that the first load detection result is normal.

[0091] In some embodiments, the number of devices connected to the first interface corresponding to the first phase current (A phase current), i.e., the first number, the number of devices connected to the second interface corresponding to the second phase current (B phase current), i.e., the second number, and the number of devices connected to the third interface corresponding to the third phase current (C phase current), i.e., the third number, can be counted to obtain the distribution of the number of devices connected to the three phases.

[0092] It can be understood that if the difference between any two of the first number, the second number, and the third number is greater than the number threshold, it can be determined that there is a significant difference in the distribution of devices between the two phases, and the first load detection result is abnormal, indicating that the distribution of devices on each phase is uneven, which may cause an unbalanced load on the system. Correspondingly, if the difference between all numbers is less than or equal to the number threshold, it means that the distribution of devices on each phase is relatively uniform and there is no significant difference. The first load detection result can be determined to be normal, indicating that the distribution of devices on each phase is balanced and the system runs relatively smoothly.

[0093] The distribution of the number of devices directly affects the load of the phase current. If a phase has significantly more devices than other phases, it may cause the current of that phase to be overloaded, thus affecting the overall stability of the system. By comparing the number of devices in each phase, the system can identify possible load imbalances in advance and make timely adjustments to avoid system problems caused by uneven distribution of equipment. If the first load detection result is judged to be abnormal, the system can issue an early warning and take measures to balance the load of each phase through further detection and adjustment to ensure the safe operation of the power system.

[0094] In some embodiments, the second load detection result may be determined by: First, if any one of the first-phase total current, the second-phase total current and the third-phase total current is greater than the current threshold, the second load detection result is determined to be abnormal; Next, if each of the first-phase total current, the second-phase total current, and the third-phase total current is less than or equal to the current threshold, it is determined that the second load detection result is normal.

[0095] In some embodiments, the system can calculate and obtain the total current of the first phase , Second phase total current (the sum of the currents of phase B) and the total current of the third phase (The sum of the C-phase current) reflects the current load of all connected devices on each phase.

[0096] Then, the system can compare the total current of the first phase, the total current of the second phase, and the total current of the third phase with a preset current threshold. for comparison. The current threshold is a maximum safe current value preset by the system, which is used to measure whether the current load of each phase is within a safe range. If any of the total current of the first phase, the total current of the second phase, or the total current of the third phase exceeds the current threshold, the system can determine that the load of the phase is too large and there may be a risk of overload, and determine that the second load detection result is abnormal, indicating that the current load of a phase is too high, which may have an adverse effect on the stability and safety of the system. Correspondingly, if the total current of all phases is less than or equal to the current threshold, it means that the current load of each phase is within a safe range and no phase is overloaded. The system can determine that the second load detection result is normal, indicating that the current load of each phase is balanced and the system is operating normally and safely.

[0097] In some embodiments, the method of the present application further comprises: First, when the second load detection result is abnormal, determining the current abnormality degree of the phase total current of the abnormal phase; Next, according to the degree of current abnormality, the number of devices connected to each phase and the total phase current are adjusted.

[0098] Among them, the current abnormality can be expressed as: (single-phase total current-maximum total current) / ( ), the single-phase total current refers to The maximum total current is one of The corresponding upper limit value. If the value is equal to 0, the current is theoretically balanced. If the value is greater than the preset threshold BI, it is determined to be current unbalanced, and the current unbalance state is reported to the system, and the host prompts the current unbalance.

[0099] It can be understood that the calculated value reflects the degree of current imbalance between the phases in the system. If this value is large, it means that there is a significant imbalance in the current distribution of the system. The system can adjust the number of devices connected to each phase according to the magnitude of the current anomaly. Specifically, the system can reduce the number of devices connected to the high-load phase and transfer these devices to the low-load phase. If the current anomaly of phase A is too high, the system can transfer some devices from phase A to phase B or phase C to reduce the total current of phase A. After adjusting the number of connected devices, the total current of each phase will also be adjusted accordingly. The goal is to make the current of each phase more balanced by redistributing the equipment, thereby reducing the current anomaly. This adjustment is dynamic. The system will continuously monitor the adjusted current situation and further optimize the load distribution until the current of each phase reaches an ideal balance.

[0100] In some embodiments, the load balancing result is determined by: First, if any one of the first load detection result and the second load detection result is abnormal, the load detection result is that the load balancing is abnormal; Next, if the first load detection result and the second load detection result are both normal, the load detection result is that the load balancing is normal.

[0101] It can be understood that the first load detection result is a preliminary judgment based on the number distribution of devices on each phase, and the second load detection result is a more accurate load assessment based on the total current value of each phase. If either the first load detection result or the second load detection result is judged to be abnormal, the system will judge the final load detection result as a load balancing abnormality. This judgment method can ensure that even if a problem occurs in one detection, the system can promptly identify the risk of load imbalance, prompt possible power system problems, and avoid potential failures.

[0102] Correspondingly, if both the first load detection result and the second load detection result are normal, the system determines the final load detection result as normal load balancing. This determination method indicates that the distribution of the equipment on each phase and the current load are in a balanced state, the system is operating normally, and there is no overload or uneven distribution.

[0103] This application adopts this dual determination mechanism to ensure that the system can promptly identify and respond to load imbalance problems, thereby ensuring the safety and stability of the power system.

[0104] Step 104: Generate a load adjustment instruction for each of the devices according to the load detection result, and perform load balancing adjustment on each of the devices.

[0105] It can be understood that when the load detection result is abnormal, it means that there is a risk of overload in the current of a certain phase in the current system, and a load adjustment instruction for the overloaded phase needs to be generated to perform load balancing adjustment on the equipment in the overloaded phase.

[0106] In some embodiments, load balancing is performed on the device in the following manner: First, when the load balancing is abnormal according to the load detection result, a load adjustment instruction is generated; Next, according to the load adjustment instruction, the number of phases of each device connected to the first phase, the second phase and the third phase is adjusted to be close to or equal; Finally, according to the load adjustment instruction, the total single-phase current generated by the regulating device connected to each phase tends to be close to or equal to the upper limit current of each phase.

[0107] In some embodiments, the system can comprehensively analyze the first load detection result and the second load detection result. If any result shows an abnormality, the system will determine that the load balancing is abnormal. When the load balancing abnormality is detected, the system automatically generates a load adjustment instruction for reallocating the access of the equipment on each phase and adjusting the power load to restore the balance of the system.

[0108] In some embodiments, based on the generated load adjustment instructions, the system can adjust the number of devices connected to the first phase (phase A), the second phase (phase B), and the third phase (phase C). The adjusted number of devices connected between the phases should be close to or equal to each other so that the distribution of devices in each phase is more balanced.

[0109] It should be noted that the specific evaluation criteria for the phase number approaching can be set as follows: the difference between the phase numbers of any two of the first phase, the second phase and the third phase should be less than a preset setting value, indicating that the difference between the number of devices connected to each phase should be within an acceptable range to ensure that no single phase is overloaded. For example, the setting value can be 1. If the number of devices connected to phase A is 10 and the number of devices connected to phase B is 9, then the number of devices currently connected to phase A and phase B is approaching.

[0110] After adjusting the number of connected devices, the system can further adjust the single-phase total current of each phase according to the load adjustment instruction. The adjusted single-phase total current should be close to or equal to the upper limit current of each phase (that is, the maximum safe current allowed by the system), ensuring that the power load is evenly distributed among the phases and avoiding the current load of any phase exceeding the safety limit. It should be noted that the standard for the single-phase total current to be close to the upper limit current of each phase can be that after adjustment, the difference between the actual current load of each phase (single-phase total current) and its upper limit current should be as small as possible to ensure that the system operates within a safe range.

[0111] It should also be noted that for the scenario where single-phase loads and three-phase loads are mixed, the number of three-phase loads can be guaranteed to be an integer multiple of 3 as much as possible, and the rest are all connected to single-phase loads, so that the number of connected phases is basically the same, and the phase currents of each phase of the incoming line are also basically the same, so that the system achieves load balance.
