Abstract
Description
Technical Field
[0001] This invention relates to the field of communication infrastructure operation and maintenance technology, and specifically provides a method and apparatus for digital management of power systems for communication base stations. Background Technology
[0002] The power systems of communication base stations operated by communication system operators are usually designed according to standardized power system specifications. The components and power supply equipment of a single operator's power system are usually supplied by only a few suppliers, and the voltage and other parameters of the main load components of the operator are basically the same. The load components within the operator have corresponding manuals and power descriptions, which provide the main data source for calculation. At the same time, as an operator, there is a relatively clear database maintenance for the main load equipment (antenna, microwave, RRU, IDU), because in order to ensure communication quality, the information of these devices is maintained in their internal monitoring and alarm systems.
[0003] Furthermore, regarding power supply equipment or circuit equipment, such as generators, rectifiers, and batteries, there is detailed data in the operator's asset management system. Based on this information and the power system design, the load and other information of each site can be clearly calculated.
[0004] The industry currently relies on manual calculations or Excel processing, which is inefficient and prone to errors; if a construction team is commissioned to conduct the assessment, the cost is high and there may be conflicts of interest. Summary of the Invention
[0005] This invention addresses the shortcomings of the prior art by providing a highly practical digital management method for power systems of communication base stations.
[0006] A further technical objective of this invention is to provide a reasonably designed, safe, and applicable digital management device for power systems of communication base stations.
[0007] The technical solution adopted by this invention to solve its technical problem is: A digital management method for the power system of a communication base station is proposed. Based on power assessment, the method first maintains relevant information of the power equipment of the communication base station, calculates power system indicators based on the relevant information, and configures a construction order corresponding to each indicator based on the power system indicators, thereby completing the complete power system assessment and management process.
[0008] Furthermore, the communication base station power equipment includes an AC section and a DC section, wherein the AC section serves as the power supply section, providing AC power to the generator, converter, and air conditioner; The DC-AC section includes a rectifier, microwave, antenna, RRU, IDU, and battery, with the battery serving as a backup power source.
[0009] Furthermore, for microwaves, antennas, RRUs, and IDUs, the maximum power, standard power, and operating voltage are collected; for batteries, the battery capacity, number of battery connections, charging voltage, and standard battery output power are collected. The DC power supply includes a meter and a generator, where the meter includes tripping current and the generator includes apparent power.
[0010] Furthermore, the rectifier data includes rectifier capacity, number of idle rectifier modules, current load, converted voltage, and total number of modules. For converters, the power collected is the converter power; for air conditioners, the maximum power collected is the air conditioner power.
[0011] Furthermore, power assessment occurs when adding or removing load equipment at a communication base station. Two variables, Additional Load and Dismantle Load, are introduced. These variables are calculated using the maximum power and standard power of the added or removed equipment. When calculating Additional Load, the maximum power in the equipment information is used for calculation. When calculating Dismantle, if the current load index obtained from the actual survey is used, the standard power is used for the calculation; if the current load index obtained from the calculation is used, the maximum power is used for the calculation.
[0012] Furthermore, intermediate variables are defined as auxiliary calculations, and the intermediate variables are: Intermediate variable a, Margin Load redundancy capacity: When calculating DC load, 10% of the rectifier load is taken as Margin Load and used in the calculation as the actual power used. Intermediate variable b, DC Total Load: The total load of the DC system, which is calculated as the current load of the rectifier + Additional Load – Dismantle Load + MarginLoad. Intermediate variable c, AC Total Load, refers to the total load of the AC system, which is calculated as (DCTotalLoad + air conditioning power) / 0.9. The intermediate variables d and NewBatteryRequired represent the battery demand. The battery demand is calculated as (Additional Load – Dismantle Load) * 0.85 / standard battery power, where 0.85 is the power factor.
[0013] Furthermore, indicators are set for site evaluation, as follows: Indicator a, Model Addition: This indicator calculates the number of new rectifiers required. The appearance of the Model Addition indicator indicates that this communication base station needs to add rectifiers. The calculation logic is as follows: Model Additional = ABS(ROUNDUP((DC Total Load / Rectifier Capacity)-(Number of Existing Rectifier Modules)-1)) If the value of ROUNDUP((DC Total Load / Rectifier Capacity)-(Number of Existing Rectifier Modules)-1) is greater than 0, then no calculation is performed; Indicator b, DG Upgrade, is a marker for generator updates. The appearance of the DG Upgrade indicator indicates that the communication base station needs to increase the number of generators. The calculation logic is as follows: If a generator exists at the site, and the ACTOTALLoad / generator capacity > 0.8, the DGUpgrade metric is 1; otherwise, it is 0. Indicator c, Transformer Upgrade, indicates that the transformer needs to be upgraded. The appearance of the TransformerUpgrade indicator suggests that the communication site requires the addition of a voltage converter. The calculation logic is as follows: If the site has a voltage converter, and the AC Total Load / converter capacity > 0.8, the Transformer Upgrade indicator is 1; otherwise, it is 0. Indicator d, MeterUpgrade, indicates that the electricity meter needs to be upgraded, either by increasing its capacity or upgrading its voltage. The calculation logic is as follows: If the electricity meter is a single-phase meter; If AcTotalLoad / (current*voltage) > 0.8, this indicator is 1; otherwise, it is 0. If the electricity meter is a three-phase meter; If Ac Total Load / (1.732 * Current * Voltage) > 0.8, then this indicator is 1; otherwise, it is 0. The 0.8 in these two calculations is the power factor.
[0014] Indicator e, DC System Swap, indicates a complete overhaul of the DC system. The appearance of the DC System Swap indicator suggests that the entire DC system of the communication base station needs to be replaced. The calculation logic is as follows: Take the previous metric, Model Additional. If Model Additional > the number of idle modules in the rectifier, then this metric is 1; otherwise, it is 0. Indicator f, BatteryAdditional: This indicator represents the number of battery replacements required. The appearance of the BatteryAdditional indicator indicates that the communication base station's battery pack needs to be added. The calculation logic is as follows: Battery Additional = Roundup(New Battery Required – (0.5) ); A digital management device for the power system of a communication base station includes: at least one memory and at least one processor; The at least one memory is used to store a machine-readable program; The at least one processor is used to call the machine-readable program to execute a digital management method for a communication base station power system.
[0015] Compared with the prior art, the digital management method and apparatus for power systems of communication base stations of the present invention have the following outstanding advantages: (a) Improve the efficiency and accuracy of assessments: Automated calculation: The system automatically completes power increase / decrease, total load calculation, and power action recommendation through a digital system, avoiding repetitive work and human error caused by traditional manual or Excel calculations.
[0016] Real-time data integration: Directly access the operator's maintained equipment database (such as parameters for antennas, RRUs, batteries, etc.) to ensure the accuracy and consistency of input data.
[0017] (II) Optimize resource allocation and cost control: Precise construction plan recommendations: Based on core indicators (such as adding rectifiers, upgrading generators, etc.), customized construction orders are generated to avoid construction teams exaggerating their needs or over-constructing.
[0018] Cost transparency: The work order is linked to the equipment parameters (brand, capacity), and a quotation is automatically generated, reducing the inflated costs caused by human intervention.
[0019] (III) Ensuring the stability of the power system: Redundancy design: Margin Load (10% rectifier load redundancy) and AC load empirical parameter (0.9) are introduced to ensure that the system still has sufficient capacity buffer after adding equipment.
[0020] Dynamic adaptation: Supports configuration of parameters such as power factor and battery brand factor to adapt to the actual needs of different base stations.
[0021] (iv) Standardization and scalability: Unified management framework: Applicable to all operator communication base stations, compatible with various power equipment (AC / DC, rectifier, generator, etc.), supports parameter configuration of multi-brand equipment (such as Huawei / Nokia batteries and rectifiers), and adapts to heterogeneous power systems of operators.
[0022] Flexible expansion: The modular design makes it easy to add new device types or adjust the calculation logic (such as adjusting the threshold from 0.8 to other values). Attached Figure Description
[0023] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.
[0024] Figure 1 This is a schematic diagram of a framework for a digital management method for the power system of a communication base station. Detailed Implementation
[0025] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to specific embodiments. Obviously, the described embodiments are merely some embodiments of the present invention, and 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.
[0026] The following is a preferred embodiment: Example
[0027] The digital management method for the power system of a communication base station in this embodiment follows the following steps: S1. Data collection and standardized entry; The system automatically acquires static parameters of various power equipment within the communication base station from the operator's asset management system and monitoring and alarm system via data interfaces, or is manually entered by the administrator. These parameters include, but are not limited to: the maximum power, standard power, and operating voltage of load equipment (antennas, RRUs, etc.); the capacity, brand, and output power of battery packs; the capacity, number of modules, and current load of rectifiers; and the rated power, current, and voltage type of generators, converters, meters, and air conditioners. This data is structured and stored in the system database, forming a knowledge base for base station power equipment.
[0028] S2, Dynamic load change triggering and calculation; When a base station undergoes equipment changes (addition or removal), the system receives information about the changed equipment. Based on the equipment's parameters in the knowledge base, the system calculates the power change. Additional Load: The maximum power of the newly added device is accumulated.
[0029] Dismantle Load: The standard power (if based on actual survey data) or maximum power (if based on system calculation data) of the dismantling equipment is deducted.
[0030] S3, System-level power and capacity assessment calculations; The system takes the result of step S2 as input and, combined with the existing equipment data of the site in the knowledge base, automatically calculates a series of intermediate evaluation variables and final decision indicators: Calculate the DC total load and AC total load, including margin load and empirical coefficients (such as 0.9 for AC systems) to simulate engineering practice and ensure system stability.
[0031] The calculations include new battery requirements and the number of new rectifier modules added. The specific calculation logic is explained in the formulas below.
[0032] Step S4: Intelligent decision-making and construction plan generation; The system compares the various indicators calculated in step S3 with preset thresholds (such as 0.8) to determine whether specific power actions (such as upgrading the generator or replacing the electricity meter) need to be performed.
[0033] The system has a built-in configurable rule engine that associates the above judgment results with attributes such as equipment brand and capacity, and automatically generates a construction details sheet and quotation sheet containing specific construction items, equipment models and quantities.
[0034] Step S5: Output and Execution; The generated construction plan is presented to users to guide subsequent power grid renovation construction, thereby completing a closed-loop digital management process from assessment to decision-making. Example
[0035] First, we maintain relevant information about the power equipment of communication base stations. Based on this information, we can calculate the corresponding power system indicators. Based on these indicators, we can configure the construction order corresponding to each indicator, thereby completing the complete power system assessment and management process.
[0036] The power supply equipment for a communication base station typically consists of the following two parts: (1) AC section, which is the main power supply module, usually provides power to generators and AC power, and also includes some rectifier-related components. Air conditioners also often appear as AC loads in the site.
[0037] (2) DC section, usually includes rectifier, equipment (microwave, antenna, RRU, IDU, etc.) and also battery. As a communication site, in order to ensure high availability, the battery is often used as a backup power source.
[0038] The following information is primarily maintained and used for evaluation: For load device information: microwave, antenna, and RRUIDU, the following parameters are collected respectively, as shown in Table 1 (the numbers are examples):
[0039] For the battery pack, the following information is collected, as shown in Table 2:
[0040] For DC power supplies, collect the following information: Electricity meter: Trip current (A), operating voltage (V), meter type (single-phase, three-phase); Generator: Apparent power (kVA); For the rectifier, we collected the following information, as shown in Table 3:
[0041] For the converter, collect the converter power (kVA); For air conditioners, collect the maximum power (kW); In addition, since power assessment usually occurs when adding or removing load equipment at communication base stations, the following two variables, Additional Load and Dismantle Load, are introduced. These two variables are calculated using the maximum power and standard power of the added or removed equipment. When calculating Additional Load, the maximum power in the equipment information is used for calculation. When calculating Dismantle, if the current load index obtained from the actual survey is used, the standard power is used for the calculation; if the current load index obtained from the calculation is used, the maximum power is used for the calculation.
[0042] Based on the information collected above, we define some intermediate variables as auxiliary calculations for subsequent analysis; Intermediate variable a) Margin Load Redundancy capacity: When calculating DC load, in order to ensure high availability of the site and avoid the influence of load error, we take 10% of the rectifier load as Margin Load and include it in the calculation as the actual power used. Intermediate variable b) DC Total Load: The total load of the DC system. This total load is calculated as the current load of the rectifier + Additional Load – Dismantle Load + MarginLoad. Intermediate variable c) AC Total Load: The total load of the AC system. This total load is calculated as (DCTotalLoad + Air Conditioner Power) / 0.9, where 0.9 is an empirical parameter. The value of this parameter can be configured. Dividing by this value means the load of the redundant AC system, because there are some other power loads to calculate. Intermediate variable d) NewBatteryRequired: The amount of battery required. This value is calculated as (Additional Load – Dismantle Load) * 0.85 / standard battery power, where 0.85 is the power factor, which is usually determined based on the battery brand and is an empirical parameter here.
[0043] Based on the information collected above, we can calculate the following six indicators as site evaluation. Indicator a) Model Addition: This indicator calculates the number of new rectifiers required. The appearance of this indicator indicates that the communication base station needs to add rectifiers. The calculation logic for this indicator is as follows: Model Additional = ABS(ROUNDUP((DC Total Load / Rectifier Capacity)-(Number of Existing Rectifier Modules)-1)) If the value of ROUNDUP((DC Total Load / Rectifier Capacity)-(Number of Existing Rectifier Modules)-1) is greater than 0, then no calculation is performed; Indicator b) DG Upgrade is a marker for generator updates. The appearance of this indicator indicates that the communication base station needs to increase the number of generators. The calculation logic of this indicator is as follows; If a generator exists at the site, and the ACTOTALLoad / generator capacity > 0.8, the DGUpgrade metric is 1; otherwise, it is 0. Indicator c) Transformer Upgrade This indicator is for transformer upgrades. The appearance of this indicator indicates that the communication site needs to add a voltage converter. The calculation logic of this indicator is as follows; If the site has a voltage converter, and the AC Total Load / converter capacity > 0.8, the Transformer Upgrade indicator is 1; otherwise, it is 0. Indicator d) MeterUpgrade: This indicator indicates that the electricity meter needs to be upgraded, either by increasing its capacity or upgrading its voltage. The calculation logic for this indicator is as follows: If the electricity meter is a single-phase meter; If AcTotalLoad / (current*voltage) > 0.8, this indicator is 1; otherwise, it is 0. If the electricity meter is a three-phase meter; If Ac Total Load / (1.732 * Current * Voltage) > 0.8, then this indicator is 1; otherwise, it is 0. The 0.8 in these two calculations is the power factor, which can be adjusted according to actual conditions; Indicator e) DC System Swap: This indicator represents the overall update of the DC system. The appearance of this indicator indicates that the DC system of the communication base station needs to be completely replaced. The calculation logic of this indicator is as follows. This metric needs to be taken from the previous metric, Model Additional. If Model Additional > the number of idle modules in the rectifier, this metric is 1; otherwise, it is 0. Indicator f) BatteryAdditional: This indicator represents the number of battery updates. The appearance of this indicator indicates that the battery pack of this communication base station needs to be updated. The calculation logic for this indicator is as follows: Battery Additional = Roundup(New Battery Required–(0.5)) where 0.5 is an empirical parameter that can be adjusted according to the actual situation.
[0044] Based on the six main indicators above, the generated quotation / work order is flexible and versatile, supporting calculations based on calculated indicators, intermediate results, and raw data, and also supporting complex conditions such as AND, OR, and NOT. Below are a few examples: If the value of the Model Additional indicator is 1, then the value of the RectifierInstall entry in the work order will be 1. If the current Rectifier brand is Huawei and the capacity is 4000, then the corresponding HuaweiRectifier4000W will have a quantity of 1 in the work order. If the Meter Upgrader metric is 1, an entry called Installnewmeter will be added to the work order, with a quantity of 1. If the number of Battery Additional indicators is 2 and the battery brand is Nokia, then the number of NokiaBatteryInstall in the work order is 2. Example
