Description

Technical Field

[0001] This invention relates to the field of communication power supply technology, and in particular to a method, apparatus and device for regulating the power of a communication power supply. Background Technology

[0002] Currently, the traffic volume of signal base stations (such as 5G base stations) exhibits a significant "tidal effect," with huge differences in traffic load between day and night, potentially fluctuating from 30% to 80% of full load. To ensure reliability, high-power power supplies for signal base stations typically employ multiple (i.e., two or more) power modules connected in parallel and operating in a "current sharing" mode, such as using two 3KW power modules connected in parallel as a 6KW power supply for a 5G base station. However, this leads to a series of problems: 1) Low efficiency under light load: Since the efficiency curve of a power module is inverted U-shaped, taking a typical 3KW module as an example, its efficiency curve is as follows: at 20% load (600W), the efficiency is approximately 92%; at 50% load (1500W), the efficiency is approximately 97% (peak); at 80% load (2400W), the efficiency is approximately 95%. This means that when the 6KW power supply operates under a 600W total load current sharing mode, each 3KW power module only bears 300W (10% load), and the efficiency may drop below 90%. 2) Significant energy waste: The aforementioned inefficient operation under light loads during off-peak hours (such as late at night) will result in substantial unnecessary electricity expenses. 3) Decreased module lifespan: With all power modules operating together for extended periods, temperature increases accumulate, accelerating aging.

[0003] Therefore, it is crucial to automatically detect load changes, dynamically optimize power supply operation strategies, achieve automatic power adjustment on demand, improve the efficiency and lifespan of power modules, and reduce energy waste. Summary of the Invention

[0004] The purpose of this invention is to provide a power regulation method, apparatus, and device for communication power supplies, which can automatically sense load changes, dynamically optimize power supply operation strategies, realize automatic power regulation on demand, improve the efficiency and lifespan of power modules, and reduce energy waste.

[0005] To solve the above technical problems, the present invention provides a power regulation method for a communication power supply, comprising:

[0021] On the other hand, in the preset efficiency optimization power supply scheme, the power supply ratio of at least one power module is 0.

[0022] On the other hand, based on the predicted load power, and with the objective of minimizing the highest junction temperature of a single power module, a target power supply scheme is determined from a range of preset thermal equilibrium power supply schemes, including:

[0028] Based on the heat transfer power, casing temperature, and junction thermal resistance of each activated power module in the current thermal balance power supply scheme, determine the junction temperature of each activated power module in the current thermal balance power supply scheme.

[0029] On the other hand, the method also includes:

[0030] Based on the power parameter information, determine the current load power of the communication power supply;

[0031] The predicted load power of the communication power supply is determined based on the current load power, the concurrent load power in historical load power data, and a preset smoothing factor.

[0032] The present invention also provides a power regulation device for a communication power supply, comprising:

[0033] A status monitoring unit is used to acquire parameter data of the communication power supply; wherein the parameter data includes power parameter information and temperature parameter information; wherein the temperature parameter information includes ambient temperature and / or the internal critical point temperature of each power module in the communication power supply;

[0034] The mode determination unit is used to determine the target screening mode based on the temperature parameter information; wherein the target screening mode is any preset screening module, and the preset screening mode includes an efficiency optimization mode and a thermal equilibrium mode.

[0035] The first screening unit is configured to, if the target screening module is the efficiency optimization mode, determine a target power supply scheme from among the preset efficiency optimization power supply schemes, based on the predicted load power of the communication power supply and the efficiency storage information of each power module, with the goal of maximizing the overall system efficiency, and control the corresponding power modules to supply power to the load according to the target power supply scheme; wherein, the predicted load power is the load power for a preset future time period determined based on the current load power and historical load power data of the communication power supply, and the current load power is calculated from the power parameter information; the efficiency storage information includes the correspondence between each load power and efficiency;

The power supply scheme controls the corresponding power modules to supply power to the load. The predicted load power is the load power for a preset future time period determined based on the current load power and historical load power data of the communication power supply. The current load power is calculated from power parameter information. Efficiency storage information includes the correspondence between the load power and efficiency. If the target selection module is in thermal balance mode, based on the predicted load power, a target power supply scheme is determined from the preset thermal balance power supply schemes with the goal of minimizing the highest junction temperature of a single power module. The corresponding power modules are then controlled to supply power to the load according to the target power supply scheme. Both the preset efficiency optimization power supply scheme and the preset thermal balance power supply scheme include the power supply ratio information for each power module.

[0041] As can be seen, this invention utilizes the predicted load power determined based on the current and historical load power data of the communication power supply to automatically sense load changes. Furthermore, by determining the target selection mode based on temperature parameter information, it can select the required power supply scheme from an efficiency-first optimization mode and a reliability-first thermal equilibrium mode, dynamically optimizing the power supply operation strategy and achieving automatic power adjustment on demand. This improves the efficiency and lifespan of the power module and reduces energy waste. In addition, this invention also provides a power adjustment device and equipment for a communication power supply, which also has the above-mentioned beneficial effects. Attached Figure Description

[0048] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0049] Please refer to Figure 1 , Figure 1 A flowchart illustrating a power regulation method for a communication power supply provided in an embodiment of the present invention. The method includes:

[0050] Step 101: Acquire parameter acquisition data of the communication power supply; wherein, the parameter acquisition data includes power parameter information and temperature parameter information; wherein, the temperature parameter information includes ambient temperature and / or the internal key point temperature of each power module in the communication power supply.

[0051] It is understood that the communication power supply in this embodiment can be a power supply device used to power signal base stations (such as 5G base stations). The specific structure and type of the communication power supply can be set by the designer according to the practical scenario and user needs, such as... Figure 2 As shown, the communication power supply can be a 6KW communication power supply. The mains power (i.e., AC power) is connected to the surge protection distribution module (which has internal circuitry for surge protection to protect downstream equipment) through L (live wire) and N (neutral wire). The mains power is then divided into two paths to power two 3KW power modules (3KW mainboard A and 3KW mainboard B). Each power module converts AC power into DC power, outputting VOS+ and VOS-. After being managed by the surge protection distribution module, the final output (such as VOT1-7) supplies power to the load.

[0052] The system board (i.e., the power regulation device) can communicate in full-duplex with the 3KW mainboard A and 3KW mainboard B via two independent communication buses, 485-A and 485-B, of the RS-485 (a serial communication standard) protocol. It also communicates with each power module via the RS-485 protocol to monitor its status (such as voltage, current, and temperature) and control its operation. Correspondingly, the system board can connect to the surge protection power distribution module via the two independent communication buses (485-A and 485-B). It can monitor the mains input status (L, N) and work in conjunction with the surge protection power distribution module to assess the system's health status after events such as lightning strikes and surges. It can also manage the output power distribution, controlling which output is powered by which power source (mains or battery).

[0053] Correspondingly, in this embodiment, each power module in the communication power supply (such as...) Figure 2 The 3KW mainboard A and 3KW mainboard B, in addition to the traditional voltage and current control loop, can also add power regulation devices (such as...) Figure 2 The system board in the system has a fast response capability to commands, and can receive and execute precise power allocation commands from the power conditioning device to achieve the power output corresponding to the target power supply scheme according to the control of the power conditioning device.

[0054] In this embodiment, the parameter acquisition data can be key data collected from the communication power supply. The specific content of the parameter acquisition data in this step can be set by the designer according to the practical scenario and user needs. For example, the parameter acquisition data may include parameter information used to calculate the current load power (i.e., output power) of the communication power supply, such as the output current and output voltage of each power module (or power supply module); the parameter acquisition data may also include temperature parameter information, such as the ambient temperature of the communication power supply and / or the internal key point temperature of each power module in the communication power supply (i.e., the temperature at the temperature detection point inside the power module). The parameter acquisition data may also include the status parameter information of the communication power supply, such as the operating status, fault flags, and input voltage (via L, N) of each power module.

[0055] Correspondingly, the specific method for acquiring the parameter data of the communication power supply in this step can be set by the designer according to the practical scenario and user needs. For example, it can be implemented in a way that is the same as or similar to the parameter acquisition method of the communication power supply in related technologies, such as power regulation devices (e.g. Figure 2 The system board (in the system) can collect communication power supply parameter data through communication connections with various power modules and surge protection distribution modules (such as the connection of two independent communication buses, 485-A and 485-B). Figure 3As shown, in this step, the power regulation device can use the status monitoring unit as the "sensor" of the system to continuously collect all key data (i.e. parameter acquisition data), such as electrical parameter information such as the output current and output voltage of each power module and the total load current of the system (from the output bus), temperature parameter information such as the internal key point temperature of each power module and the ambient temperature, and status parameter information such as the working status, fault signs and input voltage of each power module.

[0056] Accordingly, in this embodiment, at least two power modules can be provided in the communication power supply.

[0057] Step 102: Determine the target screening mode based on the temperature parameter information; wherein, the target screening mode is any preset screening module, and the preset screening modes include efficiency optimization mode and thermal equilibrium mode.

[0058] It is understandable that the preset screening mode in this step can be a pre-set mode for screening power supply schemes, such as an efficiency optimization mode that prioritizes overall system efficiency and a thermal balance mode that prioritizes reliability (i.e., thermal balance to avoid overheating of a single device). In this step, the temperature parameter information in the parameter acquisition data is used to quickly and conveniently select the preset screening mode (i.e., the target screening mode) to be used, so as to adjust the power supply status of the communication power supply.

[0059] Correspondingly, the specific number and type of preset filtering modes can be set by the designers according to the practical scenarios and user needs. For example, preset filtering modes may include efficiency optimization mode and thermal balance mode, and may also include other filtering modes, such as a comprehensive mode that combines efficiency optimization mode and thermal balance mode. This embodiment does not impose any restrictions on this.

[0060] Accordingly, the specific method for determining the target filtering mode based on temperature parameter information in this step can be set by the designer according to the practical scenario and user needs. For example, if the temperature parameter information includes ambient temperature, it can be determined whether the ambient temperature is greater than a temperature threshold (e.g., ...). Figure 3 If the temperature parameter information includes the internal key point temperature of each power module, the target screening module is determined to be in efficiency optimization mode and proceeds to step 103 if all internal key point temperatures are less than the key point temperature threshold; otherwise, it is determined to be in thermal equilibrium mode and proceeds to step 104. This embodiment does not impose any limitations on this.

[0061] Step 103: If the target selection module is in efficiency optimization mode, then based on the predicted load power of the communication power supply and the efficiency storage information of each power module, with the goal of maximizing the overall system efficiency, a target power supply scheme is determined from each preset efficiency optimization power supply scheme, and the corresponding power module is controlled to supply power to the load according to the target power supply scheme.

[0062] The predicted load power is the load power for a preset future time period determined based on the current load power and historical load power data of the communication power supply. The current load power is calculated from the power parameter information. The efficiency storage information includes the correspondence between each load power and efficiency.

[0063] It is understood that the efficiency storage information of each power module in this embodiment can be a pre-stored correspondence between the load power and efficiency of each power module, such as the efficiency-load curve of each power module. );in, For efficiency, For load power, It can represent the relationship between efficiency and load power; such as Figure 3 As shown, in this embodiment, the efficiency mapping library can be used to store the efficiency storage information (module efficiency data) of each power module.

[0064] Furthermore, the method provided in this embodiment may also include a dynamic update process for the efficiency storage information of each power module to match the characteristics of the device after aging and ensure the accuracy of the stored efficiency storage information. For example, the efficiency storage information of the current power module can be adjusted according to the input power and output power of the current power module to achieve adaptive calibration of the efficiency storage information.

[0065] Correspondingly, the predicted load power of the communication power supply in this step can be the load power for a preset future time period (e.g., the next 15 minutes) determined based on the current load power and historical load power data of the communication power supply. The current load power of the communication power supply can be calculated using power parameter information from the parameter acquisition data. For example, using the output voltage and output current of each power module in the power parameter information, the current output power of each power module can be calculated, and the sum of the current output powers of all power modules is taken as the current load power of the communication power supply.

[0066] Correspondingly, prior to this step, a load prediction process can be included to determine the predicted load power of the communication power supply based on its current load power and historical load power data. For example, the current load power of the communication power supply can be determined based on power parameter information; the predicted load power can be determined based on the current load power, the concurrent load power in historical load power data, and a preset smoothing factor. For instance, in this embodiment, a first-order autoregressive model can be used for load prediction, which is computationally inefficient, simple, and effective, suitable for the power supply's built-in controller; that is, utilizing... To determine the predicted load power of the communication power supply; among which, It can be used to predict the load power, representing the predicted load power for the next cycle; This can represent the current load power, indicating the measured load power for the current period; It can be the load power of the same period in the historical load power data, that is, the measured load power of the same period in history (such as this time yesterday). A preset smoothing factor can be set. , The value can be set according to the fluctuation of the signal base station, and is usually taken as 0.7. For example, if the load of a signal base station is stable at around 1KW at night; =1050W, =980W, take =0.7; =0.7*1050+0.3*980=735+294=1029W, the predicted load power is about 1.03KW, and the power regulation equipment can make power allocation decisions in advance based on this.

[0067] It should be noted that the preset efficiency optimization power supply scheme in this embodiment can be a power supply scheme that can be filtered under the preset efficiency optimization mode. The preset efficiency optimization power supply scheme can include the power supply ratio information of each power module. For example, if the power supply ratio of a certain power module in the current efficiency optimization power supply scheme is 0, then when the current efficiency optimization power supply scheme is adopted, the power module can be in the off state; if the power supply ratio of a certain power module in the current efficiency optimization power supply scheme is 50%, then when the current efficiency optimization power supply scheme is adopted, the power module can be responsible for outputting 50% of the load power (such as 50% of the predicted load power).

[0068] Correspondingly, the specific number and content of the preset efficiency optimization power supply schemes in this embodiment can be set by the designer according to the practical scenario and user needs. For example, the preset efficiency optimization power supply schemes may include different activation combinations of all power modules and different power supply ratio combinations. In order to ensure that there is at least one redundant power module and improve the power supply reliability of the communication power supply, each preset efficiency optimization power supply scheme in this embodiment can set the power supply ratio of at least one power module to 0. As long as the sum of the power supply ratios of each power module in each preset efficiency optimization power supply scheme is 1 (100%), this embodiment does not impose any restrictions on this.

[0069] This step involves selecting the preset efficiency-optimized power supply scheme with the highest overall system efficiency as the target power supply scheme, provided that the predicted load power of the communication power supply is met. The specific method for determining the target power supply scheme from among the preset efficiency-optimized schemes, based on the predicted load power of the communication power supply and the efficiency storage information of each power module, with the goal of maximizing the overall system efficiency, can be set by the designer according to the usage scenario and user needs. For example, the overall system efficiency of each preset efficiency-optimized power supply scheme can be determined based on the predicted load power and efficiency storage information; the preset efficiency-optimized power supply scheme with the highest overall system efficiency can then be selected as the target power supply scheme.

[0070] Accordingly, the process of determining the overall system efficiency of each preset efficiency-optimized power supply scheme based on the predicted load power and efficiency storage information may include: determining the output power of each power module in the current efficiency-optimized power supply scheme based on the predicted load power; wherein, the current efficiency-optimized power supply scheme is any preset efficiency-optimized power supply scheme; determining the input power of each power module in the current efficiency-optimized power supply scheme based on the output power and efficiency storage information; calculating the quotient of the predicted load power and the system input power to obtain the overall system efficiency of the current efficiency-optimized power supply scheme; wherein, the system input power is the sum of the input power of each power module in the current efficiency-optimized power supply scheme.

[0071] For example, the overall system efficiency: Input power of each power module: ;in, For the overall system efficiency, To predict load power, Let i be the input power of the i-th power module in the current efficiency-optimized power supply scheme. Let i be the output power of the i-th power module in the current efficiency-optimized power supply scheme. The efficiency information of the i-th power module in the current efficiency optimization power supply scheme is stored in The corresponding efficiency value, where i represents the number of power modules in the current efficiency-optimized power supply scheme.

[0072] For example, such as Figure 2 The setup shown has two 3KW power modules (3KW motherboards A and B) for communication power supply. If the predicted load power... =1.5KW; When using the traditional current sharing scheme, that is, the power supply ratio of the two power modules is 50%; then the output power of the two power modules in this scheme is 750W; the efficiency storage information shows the efficiency of the two power modules at an output power of 750W (25% load). =93%; the total input power of this scheme =(750 / 0.93)+(750 / 0.93)≈806+806=1612W; The overall system efficiency of this scheme is... =1500 / 1612≈93.05%.

[0073] Accordingly, the preset efficiency optimization power supply scheme (i.e., the target power supply scheme) provided in this embodiment operates with a single module: the power supply ratio of the first power module is 100%, and the power supply ratio of the second power module is 0; therefore, the output power of the first power module in this scheme is 1.5KW, and the second power module is not turned on; the efficiency storage information shows that the efficiency of the first power module at 1.5KW (50% load) is... =97%; Total input power of the scheme: =1500 / 0.97≈1546W; the overall system efficiency of this scheme is... =1500 / 1546≈97.02%. It can be seen that, in the above scenario, using the target power supply scheme provided in this embodiment improves system efficiency by nearly 4 percentage points; for a 6KW base station, this can save hundreds to thousands of kilowatt-hours of electricity annually, demonstrating a significant energy-saving effect.

[0074] Furthermore, this step can also determine a target power supply scheme from among the preset efficiency optimization power supply schemes based on the predicted load power of the communication power supply, the efficiency storage information of each power module, and the status parameter information of the communication power supply, with the goal of maximizing the overall system efficiency, so as to avoid the selection of faulty power modules and invalid calculations.

[0075] Step 104: If the target screening module is in thermal balance mode, then based on the predicted load power, with the goal of minimizing the highest junction temperature of a single power module, a target power supply scheme is determined from each preset thermal balance power supply scheme, and the corresponding power module is controlled to supply power to the load according to the target power supply scheme.

[0076] The preset efficiency optimization power supply scheme and the preset thermal balance power supply scheme both include power supply ratio information for each power module.

[0077] Understandably, this step allows for the selection of the highest junction temperature of a single power module while meeting the predicted load power of the communication power supply. The minimum preset efficiency optimization power supply scheme is used as the target power supply scheme, thus shifting the decision objective from efficiency priority to minimizing thermal stress in high-temperature environments. The specific method for determining a target power supply scheme from various preset thermal balance power supply schemes based on the predicted load power and aiming to minimize the highest junction temperature of a single power module can be set by the designer according to the usage scenario and user needs. For example, the junction temperature of each enabled power module in each preset thermal balance power supply scheme can be determined based on the predicted load power and stored efficiency information; where enabled power modules are power modules with a power supply ratio not equal to 0; the preset thermal balance power supply scheme with the minimum highest junction temperature is determined as the target power supply scheme; where the highest junction temperature of the current thermal balance power supply scheme is the junction temperature of each enabled power module in the current thermal balance power supply scheme (…). The maximum value in ) ), where j represents the number of active power modules in the current thermal balance power supply scheme; the current thermal balance power supply scheme can be any preset thermal balance power supply scheme. Alternatively, the junction temperature of each active power module in each preset thermal balance power supply scheme can be determined based on the predicted load power; the preset thermal balance power supply scheme with the highest junction temperature and the lowest junction temperature can be determined as the target power supply scheme. This embodiment does not impose any restrictions on this.

[0078] Correspondingly, the specific method for determining the junction temperature of each enabled power module in each preset thermal balance power supply scheme based on the predicted load power and efficiency storage information can be set by the designer. For example, the enabled output power of each enabled power module in the current thermal balance power supply scheme can be determined based on the predicted load power; the heat transfer power of each enabled power module in the current thermal balance power supply scheme can be determined based on the enabled output power and efficiency storage information; and the junction temperature of each enabled power module in the current thermal balance power supply scheme can be determined based on the heat transfer power, casing temperature, and junction thermal resistance of each enabled power module in the current thermal balance power supply scheme.

[0079] For example, the junction temperature of each enabled power module can be determined using the following formula: ;in, It can be the junction temperature, which can represent the operating temperature of a semiconductor chip (i.e., the PN junction); The temperature can be the casing temperature, which can represent the temperature of the surface of the power device package casing. For example, it can be estimated by using the ambient temperature and a heat dissipation model. That is, the method provided in this embodiment can also include the process of using a heat dissipation model to determine the casing temperature corresponding to the ambient temperature. It can be heat transfer power, which represents the portion of power that the power device consumes and converts into heat during operation; It can be the junction-to-shell thermal resistance, which represents the thermal resistance of heat conduction from the chip junction region to the outer shell.

[0080] Among them, the heat transfer power of a certain activated power module ( ) can be used to enable the output power of the power module ( The efficiency value of the enabled power module at the enabled output power in the efficiency storage information. ) Calculated as follows .

[0081] For example, such as Figure 2 The setup shown has two 3KW power modules (3KW motherboards A and B) for communication power supply. If the ambient temperature is 45℃ and the predicted load power is 2.4KW, under the traditional single power module power supply condition: the power supply ratio of the first power module is 100%, and the power supply ratio of the second power module is 0; the first power module bears 2.4KW (80% load). =95%, ; , In this case, (Approaching the limits of silicon devices).

[0082] Accordingly, the preset thermal balance power supply scheme (i.e. target power supply scheme) provided in this embodiment provides balanced power supply to two power modules: the power supply ratio of the two power modules is 50%; each of the two power modules bears 1.2KW (40% load). =96%, per power module ; , In this case, As can be seen, in the above scenario, this embodiment can automatically trigger the thermal equilibrium mode in a high-temperature environment, reducing losses while lowering the core junction temperature by more than 35°C, greatly improving reliability, effectively preventing thermal derating, and extending the power module lifespan by more than 30%.

[0083] Furthermore, after step 103 or step 104, the method provided in this embodiment can also control the corresponding power modules to supply power to the load according to the target power supply scheme. For example, it can generate precise and executable control signals (i.e., precise power allocation instructions) according to the target power supply scheme and send them to each power module. The precise power allocation instructions may include switching frequency adjustment instructions to optimize efficiency by fine-tuning the switching frequency; they may also include current limit setting instructions to precisely allocate the output power of each module; and they may also include start-stop control instructions to control the sleep and wake-up of the power modules.

[0084] like Figure 3As shown, the power regulation device can utilize a load prediction unit to predict the load power trend in the short term (e.g., 15 minutes) based on historical load power data and the current load power, providing a basis for forward-looking control. The power regulation device can use a strategy decision unit as the "brain" of the system, integrating all information from the perception layer and the load prediction unit for power supply control. For example, the inputs to the strategy decision unit can be the current load power, predicted load power, ambient temperature, module status, and efficiency mapping library. When the ambient temperature is not higher than the temperature threshold, the "efficiency optimization mode" is activated, traversing all feasible power module combinations (i.e., preset efficiency optimization power supply schemes) to "maximize the overall system efficiency." With the objective of minimizing the maximum number of power modules and the optimal power allocation scheme, the system calculates the optimal number of power modules to be activated. When the ambient temperature exceeds a certain threshold, the system operates in a thermal equilibrium mode, aiming to minimize the highest junction temperature of any single module. With this as the primary goal, more modules are tended to be activated to distribute heat and improve reliability; the output of the strategy decision unit can be a specific "optimal control strategy," i.e., the target power supply scheme. The power regulation device can utilize the power control unit of the execution layer to receive relevant instructions from the decision layer regarding the target power supply scheme and convert them into precise power allocation instructions for the power modules.

[0085] In other words, the operations at the execution layer ultimately affect the power module, supplying power to the load of the signal base station; changes in the load are then captured by the state monitoring unit, forming a new control cycle. This closed loop ensures that the system can continuously and adaptively adjust its state, always maintaining the optimal balance between efficiency and reliability.

[0086] In this embodiment, the present invention utilizes the predicted load power determined based on the current load power and historical load power data of the communication power supply to automatically sense load changes; and by determining the target screening mode based on temperature parameter information, it can select the required power supply scheme from the efficiency-first efficiency optimization mode and the reliability-first thermal balance mode, dynamically optimize the power supply operation strategy, realize automatic power adjustment on demand, improve the efficiency and lifespan of the power module, and reduce energy waste.
