Description

Technical Field

[0001] The present invention relates to the field of electricity fee management, and in particular to an intensive electricity fee calculation system and method for an industrial park where multiple enterprises share a transformer. Background Art

[0002] Nowadays, many industrial parks are enterprise communities formed by multiple manufacturing and service enterprises of the same industry type in a fixed area. These parks aim to achieve greater environmental, economic and social benefits by jointly managing environmental and economic issues. These industrial parks are formed by multiple enterprises of the same industry type gathered in the same park to form an enterprise cluster.

[0003] For a long time, most of the power supply and distribution facilities in these industrial parks have been invested, built and maintained by the parks themselves. Park owners and property companies have added equipment maintenance, loss and even other irrelevant costs to the electricity price, intercepting the dividends of the national electricity price reduction policy, and also increasing the electricity costs of terminal enterprises in the park, damaging the business environment. The transformation of industrial parks involves many issues such as property rights, electricity, and prices. There is no precedent in the country. In order to completely solve this problem, some places have launched the "government-funded transformation of the distribution system, the power supply department undertakes the transformation and construction tasks, and finally realizes direct power supply to the end user" plan for the first time, from the original "one park, one meter package sales" to "opening up the last mile of power supply and meter reading and settlement to the park terminal". Among them, the new electricity fee calculation, apportionment, verification, and settlement model launched for the transformation of industrial parks is the core of solving the problem of industrial park meter reading to household transformation.

[0004] The difficulty and pain point of designing a new electricity fee calculation model is that there are often more than a dozen or even more enterprises and individuals sharing one or several transformers in an industrial park, and there may be diversified electricity prices for residents and industrial and commercial enterprises. Guangdong currently implements electricity price charging requirements to charge basic electricity fees for transformers used by an enterprise according to capacity or demand and the number of days of use, but does not charge basic electricity fees for users who implement residential and some industrial and commercial electricity prices. For industrial parks, how can the "basic electricity fee" for transformers shared by more than a dozen or even more enterprises and individuals be fairly and reasonably calculated and charged? If there is a user who uses electricity every other month or intermittently, how can the kilowatt-hour electricity fee and the basic electricity fee be fairly calculated and verified? What if there is a user whose electricity price is changed, added or cancelled? Therefore, how to achieve fair and reasonable calculation and allocation of electricity fees in industrial parks has become a technical problem that needs to be solved urgently. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide an intensive electricity fee calculation method and system for an industrial park, which realizes the fair and reasonable calculation and allocation of electricity fees within the industrial park, eliminates the phenomenon of "middle layer" power supply surcharge; reduces the electricity costs of terminal enterprises in the park, and improves the efficiency and transparency of electricity fee management.

[0056] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below with reference to the accompanying drawings.

[0057] In order to understand the technical solution of the present invention, the technical terms involved in the present invention are first introduced as follows:

[0058] User ID: refers to the numbering of users for the convenience of search and management. The number becomes a symbol that uniquely identifies the user.

[0059] Username: The name a user provides when registering and opening an account, usually an individual, company, or other related name.

[0060] Electricity usage categories: Power grid companies classify users according to the nature of their electricity usage. The most common categories are public transformer customers (referring to users who use public transformers owned by the power supply company, most of which are residential electricity users), public line dedicated transformer customers (referring to users who use transformers owned by the power supply company's lines and are owned by the users, including industrial and commercial users with large electricity consumption), dedicated line dedicated transformer customers (referring to users who use lines and transformers owned by the users, mainly industrial and commercial users with large electricity consumption), local power plant users, and substation assessment users.

[0061] Transformer rated capacity: A basic parameter of a transformer, which refers to the maximum capacity that can be continuously output during the specified normal service life. It is the usual value of the apparent power under the main tap and will be marked on the transformer nameplate when leaving the factory.

[0062] Contract capacity: refers to the total capacity of the user's power receiving equipment permitted by the power supply department and included in the power supply contract (the specific value will be stated in the contract), which is usually less than or equal to the maximum capacity of the connected transformer.

[0063] Voltage level: It is the rated voltage level series of power systems and power equipment. It is usually divided into low voltage (220V or 380V), high voltage (10kV-220kV), and ultra-high voltage (330kV-750kV).

[0064] Metering method: It refers to the metering and installation method of the electric energy metering device, which is divided into high supply and high metering (the voltage at the setting point of the electric energy metering device is consistent with the power supply voltage and is above 10(6)kV), high supply and low metering (the voltage at the setting point of the electric energy metering device is lower than the user's power supply voltage), and low supply and low metering (the voltage at the setting point of the electric energy metering device is consistent with the user's power supply voltage. For example, most residential electricity consumption is low supply and low metering).

[0065] Metering point: refers to the location where the metering device is installed. Metering points are divided into electricity customer billing points and gateway metering points.

[0066] Metering point relationships: master-slave relationship, large-volume high-demand segmented relationship, cross-household total and division, shared self-supplied relationship, master-sub-metering, etc. are combinations made for correct billing and special conditions at the metering point site.

[0067] Metering point usage: mainly divided into reference meter (for measuring line loss and line load but not for calculating electricity charges) and general billing meter (for measuring power consumption as the basis for electricity bill settlement)

[0068] Electricity usage category at metering point: Based on the second-level classification under the major electricity usage categories, there are general industry and commerce and others, residential life, large industrial electricity, commerce, agricultural irrigation, local power plants, etc.

[0069] Electricity calculation method: divided into metering, fixed ratio (settlement based on a certain ratio of total electricity), fixed quantity (settlement based on a fixed amount of electricity each time)

[0070] Fixed quantity and fixed ratio: a fixed electricity settlement value agreed upon with the user and specified in the contract.

[0071] Electricity price: The full name is sales electricity price, which refers to the price at which power grid operators sell electricity to end users. Sales electricity price is government-set, with unified policies and hierarchical management. The pricing methods include two-part electricity price and single-part electricity price.

[0072] Basic electricity fee calculation method: The basic electricity fee calculation method for transformers in the two-part electricity price billing is based on maximum demand, transformer capacity, and actual maximum demand.

[0073] Demand Approval Value: refers to the maximum demand that the user can use according to the agreement. If the user's actual maximum demand exceeds the approved value by 5%, the basic electricity fee for the part exceeding 5% will be doubled.

[0074] Maximum demand: refers to the average power consumed by customers during a certain period of time (15 minutes currently implemented in my country) within a certain settlement period (generally one month). The largest single indication value is retained as the maximum demand for this settlement period.

[0075] Power factor assessment methods: divided into two methods: standard assessment and no assessment.

[0076] Power factor standard: divided into three types: assessment standard 0.8, assessment standard 0.85, and assessment standard 0.9. The basis and standard for adjusting electricity charges based on power factor is the document "Power Factor Adjustment Method" jointly issued by the former Ministry of Water Resources and Electric Power and the State Price Bureau in 1983.

[0077] Damage billing flag: divided into two types: yes or no.

[0078] Transformer loss: The full name is transformer loss, which refers to the sum of no-load loss Po, short-circuit loss Pk and stray loss Ps. A transformer in operation will also consume a certain amount of electrical energy.

[0079] Transformer operation days: an important parameter for calculating the basic electricity fee. Usually, the transformer operation days for monthly billing are 30 days. If it is not a full month, the basic electricity fee of the transformer will be calculated based on the number of operation days.

[0080] Basic electricity fee sharing method: divided into proportional sharing without charging, sharing by proportional value, sharing by capacity proportion, and sharing by fixed value. It is an important parameter when calculating the basic electricity fee.

[0081] Work order: refers to the work order in the business process, including user (transformer) new installation, reclassification, transfer, capacity increase, capacity reduction, meter replacement, suspension, resumption, non-permanent capacity reduction, non-periodic billing, account cancellation, etc.

[0082] Periodic billing and non-periodic billing: Normal periodic billing is to settle electricity charges on a monthly basis, while non-full-month electricity charge settlement is called non-periodic billing.

[0083] Co-transformation: refers to the situation where multiple users share one or several transformers. Most of the existing users are left over due to historical reasons, and current policies do not allow the emergence of new co-transformation users.

[0084] Power supply mode: usually there are four modes: public line dedicated transformer power supply, dedicated line dedicated transformer power supply, shared dedicated transformer power supply, and public transformer power supply.

[0085] Power factor adjustment fee: Power factor adjustment fee, also known as power factor adjustment fee, is the relevant electricity fee charged by the power supply company based on the average power factor calculated by the customer based on the active and reactive power used by the customer over a period of time. If the user's power factor is high, it means that the utilization efficiency of their electrical equipment is high, and they may get a discount on electricity fees; conversely, if the power factor is low, they may need to pay extra electricity fees. The power factor is set according to the user's electricity category, electricity price and transformer capacity, and is divided into three categories: 0.8 / 0.85 / 0.9.

[0086] like Figure 1 FIG. 1 is a schematic diagram showing a structure of an embodiment of an industrial park intensive electricity fee calculation system provided by the present invention; and FIG. Figure 2 As shown, in this embodiment, the industrial park intensive electricity fee calculation system 1 includes:

[0087] The data interaction module 10 is used to extract the basic data of industrial park users from the power grid marketing system database, including meter reading codes, files, electricity consumption, electricity prices and electricity fee calculation information; it can be understood that the data interaction module 10 extracts all basic data related to meter reading codes, files, electricity consumption, electricity prices and electricity fee calculation in the region from the power grid integrated marketing system database. The marketing system can be regarded as a database containing all regional power grid purchase and sales information. This system has a direct docking interface with the marketing system, so all the required basic data information of industrial park users can be obtained from the database.

[0088] The user setting module 11 is used to classify each industrial park user, set the owner account and at least one terminal account, and add extended attributes to these users to distinguish their roles, and verify the correctness of the user settings; the extended attributes are the industrial park owner and the industrial park terminal account;

[0089] The comprehensive calculation module 12 is used to perform intensive calculation of the electricity charges of users in the industrial park according to the set rules and algorithms, including adding user attribute extension tags, setting user relationships, clarifying charging details, setting billing files, and algorithms and rules for basic electricity charge sharing calculation;

[0090] The system verification module 13 is used to verify the correctness of the calculation results to ensure that the power consumption of the main households in the industrial park is greater than the sum of the power consumption of the terminal households, and the basic electricity fee of the transformer of the main households is greater than the sum of the basic electricity fees of the terminal households.

[0091] More specifically, the user setting module 11 further includes:

[0092] The user classification unit is used to classify users in the industrial park into owner households and terminal households, and add corresponding extended attributes for each type of user; specifically, the user classification unit classifies each industrial park user into an owner household and multiple terminal households. Each industrial park must have at least one owner household, and the remaining users are terminal households. All users in each industrial park are set with the same customer number for distinction. The industrial park owner households and terminal households need to add the extended attributes "industrial park owner" and "industrial park terminal household" respectively. The user categories of the industrial park owner households and terminal households are all dedicated customers. By analogy, the industrial park owner households can be compared to landlords, and the terminal households can be compared to tenants;

[0093] The relationship setting unit is used to establish the total-subordinate relationship between the industrial park owner and the terminal households, and ensure that all related users are located in the same meter reading section;

[0094] The verification unit is used to verify the count of the industrial park customer number to ensure that the number and relationship between the owner and the terminal meet the preset conditions. In an example, assuming that the count of the industrial park customer number is X, the industrial park owner is Y1, and the industrial park terminal is Y2, it must meet the following conditions: X = Y1 + Y2 and both Y1 and Y2 are greater than or equal to 1. Otherwise, it means that there is a corresponding error, and the staff needs to check and correct the industrial park user file in time.

[0095] In a specific example, the comprehensive calculation module 12 further includes:

[0096] The user attribute extension module is used to add extended attributes to the industrial park owner households and terminal households, and set the user category, including: adding the "industrial park owner" extended attribute to the industrial park owner households; adding the "industrial park terminal household" extended attribute to the industrial park terminal households; setting the user category of the industrial park owner households and terminal households to dedicated transformer customers;

[0097] The user relationship setting module is used to set the relationship between the industrial park owner and the terminal user, and ensure the consistency of metering and billing; including: associating the industrial park owner's metering point with the terminal user's metering point through the total-subordinate relationship; ensuring that the park owner's household and the terminal user are in the same meter reading section to achieve simultaneous meter reading and simultaneous billing; uniformly taking the actual power factor of the park owner's household as the actual power factor of all users; ensuring that the metering method of the industrial park terminal user is consistent with that of the owner's household;

[0098] Specifically, in the user relationship setting module, the relationship between the industrial park owner and the terminal household is set. First, due to the electricity deduction relationship between the owner household and the terminal household, the industrial park owner's metering point and the terminal household's metering point need to be associated through the total-to-part relationship. Note that the file is set as "total-to-part relationship" instead of "total-to-part relationship (main meter)". Second, the park owner households and terminal users who establish a total-to-part relationship need to be maintained in the same meter reading section, and strict simultaneous meter reading and billing are implemented. Third, the industrial park uniformly uses the actual power factor of the park owner household (i.e. the total meter) as the actual power factor of all users who establish a total-to-part relationship. Industrial terminal households do not need to record the total positive reactive power and maximum demand, and the archives do not need to maintain the representation type of the total positive reactive power and maximum demand. Fourth, the metering method of the metering point of the terminal household in the industrial park must be consistent with the metering point of the owner household.

[0099] The charging details clarification module is used to clarify the electricity fee sharing rules and billing standards for end users in the industrial park; including: dividing the end user electricity fee into three parts: basic electricity fee sharing, kilowatt-hour electricity fee, and power factor adjustment electricity fee; allocating the basic electricity fee according to the proportion of sub-meter electricity consumption to the total meter electricity consumption; implementing the kilowatt-hour electricity fee according to the total meter electricity price (time-of-use electricity price for electricity category and voltage level); calculating the power factor adjustment electricity fee according to the total meter power factor assessment standard;

[0100] The billing file setting module is used to set billing files for different types of users, including basic electricity fee calculation method, electricity price, power adjustment assessment standards, etc.; including: for regular users, the billing file is consistent with the main metering point, and the basic electricity fee allocation method is allocated according to the proportion of electricity consumption. Specifically, its basic electricity fee calculation method must be consistent with the main metering point, the electricity price is consistent with the main metering, the power adjustment assessment standard is consistent with the main metering, the basic electricity fee allocation method is "allocated according to the proportion of electricity consumption", and the basic electricity fee allocation value is empty; for special electricity price users (such as residents, charging piles, 5G base stations), set corresponding billing files and power adjustment assessment standards according to their electricity consumption characteristics and capacity;

[0101] For users with special electricity prices:

[0102] 1. Residents (corresponding to terminal users B): The combined meter electricity price for residents is not subject to assessment of power regulation, and participates in the basic electricity fee sharing. After sharing, no charge is made. For users of school combined meter electricity price (institutional combined meter electricity price) with a power consumption capacity of less than 100 kVA, power regulation is not assessed (see archive setting case B1 for details). If the power consumption capacity is greater than or equal to 100 kVA or above, the power regulation assessment standard for terminal users of school combined meter electricity price (institutional combined meter electricity price) is 0.85 (see archive setting case B2 for details).

[0103] 2. Charging piles (corresponding to terminal household C): Charging piles need to participate in the basic electricity fee sharing, and the basic electricity fee is not calculated. The electricity price must select the corresponding main metering electricity price with "charging". The power adjustment standard needs to be formulated after summarizing the industrial capacity of the park households (see C, C1, C2 in the file setting case 2 for details).

[0104] 3. 5G base station (corresponding to terminal user D): If the power consumption capacity of the 5G base station is less than 100 kVA (kW), it will not be assessed for power regulation, will not participate in the basic electricity fee sharing, and will not be charged for basic electricity fees. If the power consumption capacity of the 5G base station is greater than or equal to 100 kVA (kW), it is necessary to share the basic electricity fee of the park total meter and assess power regulation according to the proportion of electricity consumption (the implementation method for the case where the power consumption capacity is greater than or equal to 100 kVA is set in D1 and D2 of situation 1). The basic electricity fee sharing calculation module is used to calculate the basic electricity fee that each user should share according to user classification and power consumption; formulate algorithms and rules for basic electricity fee sharing calculation; consider the correlation between power regulation standards and electricity prices and capacity ranges to ensure the accuracy and fairness of sharing.

[0105] The basic electricity fee sharing calculation module is used to calculate the basic electricity fee that each user should share according to user classification and electricity consumption; formulate algorithms and rules for basic electricity fee sharing calculation; consider the correlation between power regulation standards and electricity prices and capacity ranges to ensure the accuracy and fairness of sharing.

[0106] The verification data module is used to verify the above data. The data must meet the following conditions: the power consumption of the main households in the industrial park is greater than the sum of the power consumption of the terminal households; the basic electricity fee of the transformer of the main households in the industrial park is greater than the sum of the basic electricity fees of the terminal households.

[0107] Specifically, in the basic electricity fee sharing calculation module, the power regulation standard value is related to the electricity price and capacity range; specifically, the average power factor is calculated based on the reactive power used by the customer within a period of time (such as a month or a year), and the relevant electricity fee is charged accordingly.

[0108] The basic electricity charge is calculated based on the customer's transformer capacity or maximum demand and the basic electricity price approved by the state.

[0109] Five basic electricity cost allocation models are used in the basic electricity cost allocation calculation module, including:

[0110] Category 1: For households that use high-power supply and high-metering electricity or industrial electricity, and whose transformer operating capacity is greater than 160kVA, the basic electricity fee is calculated as "based on transformer capacity";

[0111] Among them, base station users with a capacity of less than or equal to 100 kVA do not participate in the basic electricity fee sharing of the park, and the basic electricity fee is set to "not calculated". The basic electricity fee sharing method is set to "share by electricity consumption ratio" only for standardizing park files. In fact, the basic electricity fee will not be shared by electricity consumption ratio, and the total basic electricity fee of the park will not be undercharged. For example, as shown in Table 1:

[0112] Table 1

[0113]

[0114]

[0115] The second category is that the owner of the household uses high-power supply and high-metering, other types of electricity, and the operating capacity of the transformer is greater than 160kVA. The basic electricity fee calculation method is "based on transformer capacity"; an example is shown in Table 2 below:

[0116] Table 2

[0117]

[0118] The third category is for owners who use high-supply and low-metering electricity for industrial purposes, and whose transformer operating capacity is greater than or equal to 100kVA and less than or equal to 160kVA. The basic electricity fee calculation method is "based on transformer capacity"; an example is shown in Table 3 below:

[0119] Table 3

[0120]

[0121] The fourth category is that the main household uses high supply and low metering, industrial electricity, and the transformer operating capacity is less than 100kVA. The basic electricity fee calculation method is "not calculated"; an example is shown in Table 4 below:

[0122] Table 4

[0123]

[0124] The fifth category is for owners who use high-supply and high-metering electricity for industrial use, and whose transformer operating capacity is greater than 3000kVA. The basic electricity fee calculation method is "based on actual maximum demand". An example is shown in Table 5 below:

[0125] Table 5

[0126]

[0127] It is understandable that in the technical solution of the present invention, a standardized judgment execution process is set up, and a rigorous, quantitative, and modeled method is adopted to set the key parameters of the judgment, wherein the parameter values ​​can be flexibly adjusted according to different local conditions. The setting, calculation, and deduction of the original archives and the shared basic electricity charges require experts who are familiar with the settlement system and have a deep understanding to be well executed and completed. At present, the executors only need to operate according to the standardized settings, and an ordinary staff member can complete it according to the method after a simple training. By improving the core judgment logic, the scope of application of this method is wider, and the judgment quality and accuracy are also effectively improved. The system verification check logic is added to avoid possible errors and risks of manual entry. At the same time, the present invention has good scalability.

[0140] Step S112, clarifying the charging details, clarifying the electricity fee sharing rules and billing standards for end users in the industrial park; including: dividing the end user electricity fee into three parts: basic electricity fee sharing, kilowatt-hour electricity fee, and power factor adjustment electricity fee; allocating the basic electricity fee according to the proportion of sub-meter electricity consumption to the total meter electricity consumption; implementing the kilowatt-hour electricity fee according to the total meter electricity price; calculating the power factor adjustment electricity fee according to the total meter power factor assessment standard;
