[0033] Obtaining power supply demand information of a target building; the target building refers to a building that needs to undergo power supply system transformation;

[0040] The above mainly introduces the scheme of the embodiment of the present application from the perspective of the execution process on the method side. It is understandable that, in order to realize the above functions, the electronic device includes a hardware structure and / or software module corresponding to the execution of each function.

Whether a function is executed in the form of hardware or computer software driving hardware depends on the specific application and design constraints of the technical solution. Professional and technical personnel can use different methods to implement the described functions for each specific application, but such implementation should not be considered to be beyond the scope of the present application.

[0041] The steps not described in detail above can be found in Figure 2 The description of the steps of the method will not be repeated here.

[0042] The present application provides a method for determining a household DC voltage level, which is applied to Figure 1 The electronic equipment shown, such as Figure 2 As shown, the method includes steps S21 to S26:

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

[0044] Among them, the target building refers to a building that needs to undergo power supply system transformation. The power supply demand information is used to indicate the power supply type, load capacity, power supply distance, and the currently used household AC distribution voltage level of the target building. Among them, the power supply demand information includes the target building type of the target building; the electronic device can determine the target power supply type corresponding to the target building type based on the target building type and the first relationship, and the first relationship includes the correspondence between the building type and the power supply type. If the building type is a residence or a data center, the corresponding power supply type is civil power supply. In other words, if the power supply demand information includes that the target building is a residence or a data center, it can be determined that the power supply type of the target building is civil power supply.

[0045] S22: If the power supply type indicated by the power supply demand information is civil power supply, obtain a first DC voltage level basic value set corresponding to the civil power supply.

[0046] The first DC voltage level basic value set includes at least one basic value; each basic value of the at least one basic value is less than the first threshold value. The first threshold value refers to the minimum value of the DC power supply voltage at which the contact voltage of the metal casing of the live equipment in the building will cause electric shock damage to the user when a live conductor in the building has a grounding fault. In practical applications, the first threshold value may be 240V. Electric shock, also known as electric shock, refers to a certain amount of current passing through the human body causing varying degrees of tissue damage or organ dysfunction or sudden death. The first DC voltage level basic value set can be determined based on industry standards and / or application habits. For example, in the field of communications industry, 48V and 400V are the most commonly used DC voltage levels; experts and scholars at home and abroad have suggested that 0.19kV / 0.38kV be used as the DC voltage level of the building power supply system; the "Guidelines for Voltages of Medium and Low Voltage DC Distribution Networks" issued by my country also include 1000V, 750V, 600V, 220V, 110V and other related voltage selection values. Therefore, the first DC voltage level basic value set may include 220V, 190V, 110V, etc.

[0047] S23. Determine, based on the power supply demand information, a matching score between the target building and each basic value in the first DC voltage level basic value set.

[0048] The following is a detailed introduction to a method for determining a base value matching score in an embodiment of the present application.

[0049] See also Figure 3 , Figure 3 A flow chart of a matching score determination method provided in an embodiment of the present application. Figure 3 As shown, the matching score determination method (i.e., determining the matching score between the target building and each basic value in the first DC voltage level basic value set according to the power supply demand information) specifically includes performing the following operations for each basic value:

[0050] Step A1: Determine the withstand voltage value of the electrical equipment in the target building according to the current household AC power distribution voltage level.

[0051] Electrical equipment includes the following: heating equipment, incandescent lamps, heating systems, air conditioning systems, kitchens and other large household appliances, building power supply systems, data centers and electric vehicles. The withstand voltage value of electrical equipment refers to the maximum working voltage that the insulation of electrical equipment can withstand. Each household AC 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, step A2 is executed. Step A2 is to determine that the matching score is the minimum value.

[0053] It is understandable that if the current basic value is greater than the withstand voltage value, the original electrical equipment may be easily damaged. Ensuring that the current basic value is greater than the withstand voltage value and determining the matching score to be the minimum value can ensure that the current basic value is not selected as the target household DC voltage level, thereby ensuring the safety of the power supply system transformation.

[0054] After step A1, if the current basic value is less than or equal to the withstand voltage value, step A3 is executed, and step A3 is to obtain cable information of at least one first cable model corresponding to the current basic value. The cable information includes transaction information and copper consumption information.

[0055] After step A3, step A4 is performed. Step A4 includes performing the following operations for each first cable model according to the cable information of at least one first cable model:

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

[0057] Among them, the target power supply radius is the power supply radius when the voltage drop of the power supply circuit is equal to the threshold when power is supplied by the current basic value and the cable of the second cable model is used for power transportation.

[0058] Among them, the target power supply radius is the power supply radius when the power supply circuit voltage drop is equal to the threshold value when the current basic value is used for power supply. Obviously, the target power supply radius can be calculated based on the power supply circuit voltage drop. In a specific implementation, the threshold value can be set as needed, for example, the threshold value can be 5%, 10%, and the power supply circuit voltage drop refers to the voltage value lost by the circuit impedance of the power supply circuit during the power transmission process.

[0059] After step A41, if the target power supply radius is smaller than the power supply distance, step A42 is executed, and step A42 is to determine that the matching score is the minimum value.

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

[0061] Further, the determining of the matching score of the second cable model according to the transaction information and / or the copper consumption information can be implemented in at least the following three ways:

[0062] Method 1: Determine the matching score based on the cable cost and the cable 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; determine the matching score of the second cable model based on the preset cost weight, copper consumption weight, cable cost, and cable copper consumption.

[0063] Optionally, the correspondence between the cable cost, the unit price of the second cable model, and the power supply distance may 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 according to the first product and a cost fluctuation index. Cable cost = cost fluctuation index * first product. The cost fluctuation index may be provided by a third party. No specific limitation is given here.

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

[0066] Among them, the correspondence between the matching score of the second cable model and the preset cost weight, copper consumption weight, cable cost, and cable copper consumption is: Y=AX1+BX2, 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 protection cost corresponding to the cable copper consumption, X2=CH, C is the environmental protection cost generated by the preparation of unit cable copper consumption, in yuan / m, and H is the cable copper consumption, in m.

[0067] It can be seen that in this method, the electronic device can determine the cable cost and the cable copper consumption, and determine the matching score of the second cable model based on the preset cost weight, copper consumption weight, cable cost, and cable copper consumption (which can determine the potential cost of cable copper, that is, the environmental cost caused by cable copper), thereby ensuring the accuracy and comprehensiveness of the matching score.

[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 proportional relationship between the cable cost and the budgeted cost.

[0069] It can be seen that 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, thereby 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; and 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 model * the power supply distance.

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

[0073] S24: Determine the target household DC voltage level with the highest matching score in the first DC voltage level basic value set.

[0074] S25. Generate a power supply strategy according to the target household DC voltage level.

[0075] The power supply strategy is used to indicate the target household DC voltage level of the target building. Specifically, the power supply strategy includes the target household DC voltage level of the target building being the target household DC voltage level.

[0076] S26: Output the power supply strategy.

[0077] Optionally, the electronic device may play the power supply strategy through a buzzer or display the power supply strategy through a display screen.

[0078] Through this application, the intelligence and accuracy of determining the household DC voltage level in the scenario of civil power supply system transformation can be improved.

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

[0080] In the case of dividing each functional module into corresponding functional modules, Figure 4 This is a functional unit block diagram of a device for determining a household DC voltage level provided in an embodiment of the present application. The device 400 for determining a household DC voltage level is applied to an electronic device. The device 400 for determining a household DC voltage level includes:

[0086] The output unit 406 is configured to output the power supply strategy.

[0087] It can be seen that, through the above-mentioned household DC voltage level determination device, the power supply demand information of the target building is first obtained; the target building refers to the building that needs to undergo power supply system transformation; if the power supply type indicated by the power supply demand information is civil power supply, then the first DC voltage level basic value set corresponding to the civil power supply is obtained; according to the power supply demand information, the matching score between the target building and each basic value in the above-mentioned first DC voltage level basic value set is determined; the target household DC voltage level with the highest matching score in the above-mentioned first DC voltage level basic value set is determined; a power supply strategy is generated according to the target household DC voltage level, and the power supply strategy is used to indicate the target household DC voltage level of the target building; and the power supply strategy is output. Through this application, the intelligence and accuracy of household DC voltage level determination in the scenario of civil power supply system transformation can be improved.

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

[0091] Perform the following operations for each first cable model according to the cable information of at least one first cable model:

[0092] Determine a target power supply radius corresponding to the second cable model currently being processed, the target power supply radius being a power supply radius when the voltage drop of the power supply loop is equal to a threshold value when power is supplied at the current basic value and when the cable of the second cable model is used for power transportation;

[0093] If the target power supply radius is smaller than the power supply distance, the matching score is determined to be a 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 according to the transaction information and / or the copper consumption information.

[0095] In a possible example, in determining the matching score of the second cable model according to the transaction information and / or the copper consumption information, the first determining unit 403 is specifically configured to:

[0096] Determining the cable cost based on the product of the unit price of the second cable model and the power supply distance;

[0097] 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;

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

[0099] In a possible example, in determining the matching score of the second cable model according to the transaction information and / or the copper consumption information, the first determining unit 403 is specifically configured to:

[0100] Determining the cable cost based on the product of the unit price of the second cable model and the power supply distance;

[0101] Based on the proportional relationship between the cable cost and the budgeted cost, a matching score of the second cable model is determined.

[0102] In a possible example, in determining the matching score of the second cable model according to the transaction information and / or the copper consumption information, the first determining unit 403 is specifically configured to:

[0103] 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;

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

[0105] In a possible example, in determining the cable cost based on the product of the unit price of the second cable model and the power supply distance, the first determining unit 403 is specifically configured to:

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

[0107] The cable cost is determined according to the first product and the cost fluctuation index.

[0108] In a possible example, in determining the copper consumption of the cable based on the copper content per unit length of the second cable model and the power supply distance, the first determining unit 403 is specifically configured to:

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

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

[0111] It should be noted that the specific implementation of each operation can adopt the corresponding description of the method embodiment shown above, and the household DC voltage level determination device 400 can be used to execute the above method embodiment of the present application, which will not be repeated here.

[0112] In the case of an integrated unit, the following combination Figure 5 Another device for determining a household DC voltage level in an embodiment of the present application is described in detail. The device 500 for determining a household DC voltage level is applied to an electronic device. The device 500 for determining a household DC voltage level includes a processing unit 501 and a communication unit 502, wherein the processing unit 501 is used to execute any step in the above method embodiment, and when performing data transmission, the communication unit 502 can be selectively called to complete the corresponding operation.
