[0041] For steps not described in detail above, please refer to Figure 2 The steps of the Chinese method are not described in detail here.

[0042] This application provides a method for determining the DC voltage level for residential applications, applicable to, for example... Figure 1 The electronic devices shown, such as Figure 2 As shown, the method includes steps S21-S26:

[0043] S21. Obtain the power supply requirements of the target building.

[0044] The target building refers to a building that requires power supply system upgrades. Power demand information indicates the target building's power supply type, load capacity, power supply distance, and current AC distribution voltage level. This power demand information includes the target building type; electronic equipment can determine the target power supply type corresponding to the target building type based on the target building type and a primary relationship, which includes the correspondence between building type and power supply type. For example, if the building type is residential or a data center, the corresponding power supply type is residential power supply. In other words, if the power demand information indicates that the target building is a residential building or a data center, the power supply type for that target building can be determined to be residential power supply.

[0045] S22. If the power supply type indicated by the power supply demand information is residential power supply, then obtain the set of basic values ​​of the first DC voltage level corresponding to residential power supply.

[0046] The first set of basic DC voltage levels includes at least one basic value; each of these basic values ​​is less than a first threshold. The first threshold refers to the minimum DC supply voltage at which the contact voltage of the metal casing of electrical equipment in a building would cause electric shock to a user when a ground fault occurs in a live conductor in the building. In practical applications, the first threshold can be 240V. Electric shock, also known as electrocution, refers to a certain amount of current passing through the human body causing varying degrees of tissue damage, organ dysfunction, or sudden death. The first set of basic DC voltage levels can be determined based on industry standards and / or application practices. For example, in the telecommunications industry, 48V and 400V are the most commonly used DC voltage levels; domestic and international experts and scholars have suggested using 0.19kV / 0.38kV as the DC voltage level for building power supply systems; my country's "Voltage Guidelines for Medium and Low Voltage DC Distribution Networks" also includes related voltage selection values ​​such as 1000V, 750V, 600V, 220V, and 110V. Therefore, the basic set of values ​​for the first DC voltage level can include 220V, 190V, 110V, etc.

[0047] S23. Based on the power supply demand information, determine the matching score between the target building and each basic value in the above-mentioned first DC voltage level basic value set.

[0048] The following is a detailed description of a method for determining the basic value matching score according to an embodiment of this application.

[0049] Please see Figure 3 , Figure 3 This is a flowchart illustrating a method for determining a matching score, as provided in an embodiment of this application. Figure 3 As shown, the matching score determination method (i.e., determining the matching score between the target building and each base value in the first DC voltage level base value set based on the power supply demand information as described above) specifically includes performing the following operations for each base value:

[0050] Step A1: Determine the withstand voltage of electrical equipment in the target building based on the current AC power distribution voltage level.

[0051] Electrical equipment includes the following: heating equipment, incandescent lamps, heating systems, air conditioning systems, kitchen and other large household appliances, building power supply systems, data centers, and electric vehicles. The withstand voltage value of electrical equipment refers to the highest operating voltage that the insulation of the electrical equipment can withstand. Each incoming AC power distribution voltage level corresponds to a withstand voltage value.

[0052] After step A1, if the current base value is greater than the withstand voltage value, then step A2 is executed. Step A2 is to determine the matching degree score as the minimum value.

[0053] Understandably, if the current baseline value is greater than the withstand voltage value, it is easy to damage the original electrical equipment. Ensuring that the current baseline value is greater than the withstand voltage value and determining the matching degree score to be the minimum value can ensure that the current baseline value is not selected as the target DC voltage level for the household, thus ensuring the safety of the power supply system renovation.

[0054] After step A1, if the current base value is less than or equal to the withstand voltage value, then step A3 is executed. Step A3 involves obtaining cable information for at least one first cable model corresponding to the current base value. The cable information includes transaction information and copper loss information.

[0055] After step A3, step A4 is performed, which includes performing the following operations for each first cable type based on cable information of at least one first cable type:

[0056] Step A41: Determine the target power supply radius corresponding to the second cable model currently being processed.

[0057] The target power supply radius is the power supply radius when the voltage drop of the power supply circuit is equal to the threshold value, provided that the power is supplied based on the current base value and the power is transported using a cable of the second cable type.

[0058] The target power supply radius is the power supply radius when the voltage drop in the power supply circuit equals a threshold value, provided that power is supplied based on the current baseline value. Clearly, the target power supply radius can be calculated based on the voltage drop in the power supply circuit. In practice, this threshold can be set as needed; for example, it could be 5% or 10%. The voltage drop in the power supply circuit refers to the voltage loss caused by the circuit impedance during power transmission.

[0059] After step A41, if the target power supply radius is less than the power supply distance, then step A42 is executed, whereby step A42 determines the matching score to be the minimum value.

[0060] After step A41, if the target power supply radius is greater than or equal to the power supply distance, then step A43 is executed. Step A43 is to determine the matching score of the second cable model based on the transaction information and / or the copper loss information.

[0061] Furthermore, determining the matching score of the second cable model based on the transaction information and / or the copper consumption information can be achieved in at least the following three ways:

[0062] Method 1: Determine the matching score based on the cable cost and copper consumption. Specifically, determine the cable cost based on the product of the unit price of the second cable model and the power supply distance; determine the cable copper consumption based on the product of the copper content per unit length of the second cable model and the power supply distance; and determine the matching score of the second cable model based on preset cost weights, copper consumption weights, cable cost, and cable copper consumption.

[0063] Optionally, the relationship between cable cost and the unit price of the second cable model and the power supply distance can be: cable cost = unit price of the second cable model * power supply distance.

[0064] Optionally, determining the cable cost based on the product of the unit price of the second cable model and the power supply distance includes: determining a first product of the unit price of the second cable model and the power supply distance; and determining the cable cost based on the first product and a cost fluctuation index. Wherein, cable cost = cost fluctuation index * first product. The cost fluctuation index may be provided by a third party. No specific limitations are imposed here.

[0065] Optionally, the relationship between the copper consumption of the cable, the copper content per unit length of the second cable type, and the power supply distance can be: copper consumption of the cable = copper content per unit length of the second cable type * power supply distance.

[0066] The matching score of the second cable model is related to the preset cost weight, copper consumption weight, cable cost, and copper consumption as follows: Y = AX1 + BX2, where Y is the matching score of the second cable model, A is the preset cost weight, B is the copper consumption weight, X1 is the cable cost, X2 is the environmental cost corresponding to the copper consumption of the cable, X2 = CH, C is the environmental cost generated by the amount of copper used to prepare a unit of cable, in yuan / m, and H is the copper consumption of the cable, in m.

[0067] As can be seen, in this method, the electronic device can determine the cable cost and the amount of copper consumed in the cable. Based on the preset cost weight, copper consumption weight, cable cost, and amount of copper consumed in the cable (which can determine the potential cost of copper used in the cable, that is, the environmental cost caused by the use of copper in the cable), the matching score of the second cable model is determined, ensuring the accuracy and comprehensiveness of the matching score determination.

[0068] Method 2: Determine the matching score based on the cable cost. Specifically: First, determine the cable cost based on the product of the unit price of the second cable model and the power supply distance; then, determine the matching score of the second cable model based on the ratio between the cable cost and the budgeted cost.

[0069] As can be seen, in this method, the electronic device can determine the cable cost, and then determine the matching score of the second cable model based on the relationship between the cable cost and the budget cost, ensuring the accuracy of the matching score determination.

[0070] Method 3: Determine the matching score based on the copper consumption of the cable. Specifically: First, determine the copper consumption of the cable based on the product of the copper content per unit length of the second cable model and the power supply distance; then determine the matching score based on the copper consumption of the cable.

[0071] Among them, the copper consumption of the cable = the copper content per unit length of the cable type * the power supply distance.

[0072] The relationship between the matching score of the second cable model and the copper consumption of the cable is as follows: Y = ZX2, where Y is the matching score of the second cable model, Z is the copper consumption coefficient, Z can be set as needed, such as Z = 3, and there is no specific limitation on Z. X2 is the environmental cost corresponding to the copper consumption of the cable, X2 = CH, where C is the environmental cost generated by the amount of copper used to produce a unit of cable, in yuan / m, and H is the copper consumption of the cable, in m.

[0073] S24. Determine the target DC voltage level with the highest matching score in the above set of basic values ​​for the first DC voltage level.

[0074] S25. Generate a power supply strategy based on the target DC voltage level of the household.

[0075] This power supply strategy is used to indicate the target DC voltage level of the target building. Specifically, the power supply strategy includes setting the target DC voltage level of the target building as the target DC voltage level.

[0076] S26. Output the power supply strategy.

[0077] Optionally, the electronic device may announce the power supply strategy via a buzzer. Alternatively, the electronic device may display the power supply strategy on a screen.

[0078] This application can improve the intelligence and accuracy of determining the DC voltage level of a household in the scenario of upgrading a civil power supply system.

[0079] This application embodiment can divide the electronic device into functional units according to the above method example. For example, each function can be divided into a separate functional unit, or two or more functions can be integrated into one processing unit. The integrated unit can be implemented in hardware or as a software functional unit. It should be noted that the unit division in this application embodiment is illustrative and only represents one logical functional division. In actual implementation, there may be other division methods.

[0080] When dividing each function into modules according to its corresponding function. Figure 4 This application provides a functional unit block diagram of a DC voltage level determination device for residential use. The DC voltage level determination device 400 is applied to electronic equipment and includes:

[0081] The first acquisition unit 401 is used to acquire power supply demand information of the target building; the target building refers to a building that needs to have its power supply system upgraded.

[0082] The second acquisition unit 402 is used to acquire the first DC voltage level base value set corresponding to civil power supply if the power supply type indicated by the power supply demand information is civil power supply.

[0083] The first determining unit 403 is used to determine the matching degree score between the target building and each basic value in the first DC voltage level basic value set based on the power supply demand information.

[0084] The second determining unit 404 is used to determine the target DC voltage level with the highest matching degree score in the first set of DC voltage level base values.

[0085] The generation unit 405 is used to generate a power supply strategy based on the target DC voltage level of the building, the power supply strategy being used to indicate the target DC voltage level of the building.

[0086] Output unit 406 is used to output the power supply strategy.

[0087] As can be seen, the aforementioned DC voltage level determination device first obtains the power supply demand information of the target building; the target building refers to a building that requires power supply system renovation; if the power supply type indicated by the power supply demand information is residential power supply, then a first DC voltage level base value set corresponding to residential power supply is obtained; based on the power supply demand information, the matching degree score between the target building and each base value in the first DC voltage level base value set is determined; the target DC voltage level with the highest matching degree score in the first DC voltage level base value set is determined; a power supply strategy is generated based on the target DC voltage level, the power supply strategy being used to indicate the target DC voltage level of the target building; and the power supply strategy is output. This application improves the intelligence and accuracy of determining the DC voltage level in residential power supply system renovation scenarios.

[0088] In one possible example, the power supply demand information includes the reference AC distribution voltage level currently used by the target building. In determining the matching score between the target building and each base value in the first DC voltage level base value set based on the power supply demand information, the first determining unit 403 is specifically used to perform the following operation for each base value: determine the withstand voltage value of the electrical equipment in the target building based on the reference AC distribution voltage level.

[0089] If the current base value is greater than the withstand pressure value, then the matching score is determined to be the minimum value;

[0090] If the current base value is less than or equal to the withstand voltage value, then obtain cable information for at least one first cable model corresponding to the current base value, the cable information including transaction information and copper consumption information;

[0091] Perform the following operations for each first cable type based on cable information for at least one first cable type:

[0092] Determine the target power supply radius corresponding to the second cable model currently being processed. The target power supply radius is the power supply radius when the voltage drop of the power supply circuit is equal to a threshold value when the power is supplied based on the current base value and when the power is transported using the cable of the second cable model.

[0093] If the target power supply radius is less than the power supply distance, the matching score is determined to be the minimum value;

[0094] If the target power supply radius is greater than or equal to the power supply distance, the matching score of the second cable model is determined based on the transaction information and / or the copper loss information.

[0095] In one possible example, regarding the determination of the matching score of the second cable model based on the transaction information and / or the copper loss information, the first determining unit 403 is specifically used for:

[0096] The cable cost is determined by multiplying the unit price of the second cable type by the power supply distance.

[0097] The copper consumption of the cable is determined by multiplying the copper content per unit length of the second cable type with the power supply distance.

[0098] The matching score of the second cable model is determined based on the preset cost weight, copper consumption weight, cable cost, and cable copper consumption.

[0099] In one possible example, regarding the determination of the matching score of the second cable model based on the transaction information and / or the copper loss information, the first determining unit 403 is specifically used for:

[0100] The cable cost is determined by multiplying the unit price of the second cable type by the power supply distance.

[0101] The matching score of the second cable model is determined based on the ratio between cable cost and budget cost.

[0102] In one possible example, regarding the determination of the matching score of the second cable model based on the transaction information and / or the copper loss information, the first determining unit 403 is specifically used for:

[0103] The copper consumption of the cable is determined by multiplying the copper content per unit length of the second cable type with the power supply distance.

[0104] The matching score is determined based on the copper consumption of the cable.

[0105] In one possible example, regarding the determination of cable cost based on the product of the unit price of the second cable type and the power supply distance, the first determining unit 403 is specifically used for:

[0106] Determine the first product of the unit price of the second cable type and the power supply distance;

[0107] The cable cost is determined based on the first product and the cost fluctuation index.

[0108] In one possible example, regarding the determination of cable copper consumption based on the copper content per unit length of the second cable type and the power supply distance, the first determining unit 403 is specifically used for:

[0109] The second product is based on the copper content per unit length of the second cable type and the power supply distance;

[0110] The cable cost is determined based on the second product and the copper consumption floating index.

[0111] It should be noted that the specific implementation of each operation can be described in the corresponding description of the method embodiment shown above. The DC voltage level determination device 400 can be used to execute the method embodiment of this application, and will not be described again here.

[0112] When using integrated units, the following is combined with Figure 5 Another DC voltage level determination device for a household is described in detail in the embodiments of this application. The DC voltage level determination device 500 is applied to an electronic device. The DC voltage level determination device 500 includes a processing unit 501 and a communication unit 502. The processing unit 501 is used to perform any step as described in the above method embodiments, and when performing data transmission, it can selectively call the communication unit 502 to complete the corresponding operation.

[0113] The DC voltage level determination device 500 may further include a storage unit 503 for storing program code and data. The processing unit 501 may be a processor, the communication unit 502 may be a wireless communication module, and the storage unit 503 may be a memory.

[0114] The processing unit 501 is specifically used to: obtain power supply demand information of the target building through the communication unit 502; the target building refers to a building that needs to have its power supply system upgraded.

[0115] If the power supply type indicated by the power supply demand information is residential power supply, then obtain the set of basic values ​​for the first DC voltage level corresponding to residential power supply.

[0116] Based on the power supply demand information, determine the matching score between the target building and each base value in the first DC voltage level base value set;

[0117] Determine the target DC voltage level with the highest matching score in the first set of DC voltage level baseline values;

[0118] A power supply strategy is generated based on the target DC voltage level of the building. The power supply strategy is used to indicate the target DC voltage level of the building.

[0119] Output the power supply strategy.
