Description

Technical Field

[0001] This invention relates to the field of comprehensive line loss converted electricity calculation technology, and in particular to a method and system for calculating comprehensive line loss converted electricity during the same period. Background Technology

[0002] The comprehensive line loss during the same period is a performance indicator used by the superior authority of a power supply company to assess the loss reduction and efficiency improvement of its subordinate departments. It is directly related to the economic benefits of power companies and is one of their core indicators. Accurate and accurate comprehensive line loss values ​​during the same period are crucial to ensuring the achievement of this goal. The calculation formula is: Comprehensive line loss rate during the same period = (Power supply volume of the power supply bureau (station) - Total electricity consumption settled by all users within the power supply bureau (station) area) / Power supply volume of the power supply bureau (station) * 100%, where the electricity sales volume equals the sum of electricity consumption by all users within the power supply bureau (station) area during the calculation period of the comprehensive line loss during the same period, and the corresponding electricity input is the power supply volume.

[0003] As can be seen from the above, obtaining accurate electricity consumption is crucial. Currently, the power industry obtains electricity consumption in two ways: first, by obtaining accurate meter readings from the metering master station system; second, for meters where accurate electricity consumption data is unavailable, the settled electricity consumption is used as a deduction. The calculation formula is: Deduction Electricity Constituent = (Settlement Electricity Constituent / Time Span Corresponding to Settlement Electricity Constituent) * Time Span for Calculating Line Loss in the Same Period. This involves evenly distributing the settled electricity consumption across each point in time, a method of average calculation. However, in reality, electricity consumption by users on different days is usually unequal, so the electricity consumption value calculated in this way will deviate significantly from the actual value. If the inability to obtain accurate electricity consumption is due to business factors such as meter replacement, suspension of service, or account cancellation, the deviation in the deduction electricity consumption will be compounded by the impact of these business factors on top of the aforementioned deviations. Typically, various business operations involve multiple departments and nodes, and the data entry system often lags behind the actual field. Therefore, the settlement electricity displayed in the marketing system may not reflect the electricity volume for the current period of line loss calculation, or the time span corresponding to the settlement electricity volume may deviate from the actual time span. In such cases, the calculated electricity volume value obtained using the conversion formula will deviate significantly from the actual value. In the calculation of the overall line loss during the same period, where the converted electricity volume typically accounts for more than 8%, this method of using marketing settlement electricity for conversion can overestimate or underestimate the overall line loss by more than 2%. For situations like the Shenzhen Power Supply Bureau, where the overall line loss for 50kV and below is only 2.2%, this deviation is 100%, severely deviating from the actual value and failing to accurately reflect the overall line loss level of each power supply bureau (station). Consequently, the superior authorities of power supply enterprises find it difficult to use this value as a performance evaluation indicator for subordinate departments, thereby failing to achieve the goal of energy conservation, loss reduction, and efficiency improvement. Summary of the Invention

[0004] The purpose of this invention is to propose a method and system for calculating the equivalent electricity of synchronous comprehensive line loss, thereby solving the technical problem that the equivalent electricity is difficult to calculate accurately in the existing method for calculating synchronous comprehensive line loss.

[0005] On the one hand, a method for calculating the equivalent electricity volume of the comprehensive line loss during the same period is provided, including:

[0006] Obtain the last meter code information from the meter code library under the preset billing master meter metering point, wherein the meter code information includes at least the last meter code value and the time information corresponding to the value;

[0007] Based on the last meter code information, determine whether the time corresponding to the meter code information is within the time range of this line loss calculation cycle;

[0008] When the time corresponding to the meter code information is within the time range of the current line loss calculation period, the billing master meter point is used as the benchmark. The bureau code at the beginning of the current line loss calculation period is compared with the meter bureau code on the first day of the following month of the current line loss calculation period. The type of meter code information to be converted and included is determined based on the comparison result.

[0009] Once the type of meter code information is determined, extract the starting and ending codes of the meter with the longest time span within the current line loss calculation period in the metering master station.

[0010] Determine whether the ratio between the time span of the minimum and the maximum time span and the current line loss calculation period is greater than a preset judgment standard value; if not, the most recent settlement electricity volume of the marketing system is used for calculation; if so, the corresponding comprehensive line loss conversion electricity volume is calculated according to the preset calculation model.

[0011] Preferably, it further includes:

[0012] When the time corresponding to the meter code information is not within the time range of the current line loss calculation cycle, determine whether the meter is in a canceled or disabled state.

[0013] If the meter is in a canceled or deactivated state, determine whether the meter's settlement electricity for this line loss calculation period is not 0;

[0018] When the bureau code at the start of the current line loss calculation period is the same as the meter bureau code on the first day of the following month of the month in which the current line loss calculation period is located, determine whether the meter is in the reporting or new process within this month.

[0019] Preferably, determining the type of the table code information to be converted and included based on the comparison result further includes:

[0024] When the meter has not been deactivated or cancelled during the current line loss calculation period, extract the longest time span (starting and ending codes) of the meter in the metering master station within the current line loss calculation period.

[0025] Preferably, the calculation model based on the preset formula is: Metered electricity consumption = (minimum - minimum) multiplied by the multiplier / time span between minimum and minimum * time span of the line loss cycle.

[0026] On the other hand, a calculation system for the equivalent electricity of the same period's comprehensive line loss is also provided, for implementing the aforementioned calculation method for the equivalent electricity of the same period's comprehensive line loss, including:

[0027] The information acquisition module is used to acquire the last meter code information in the meter code library under the preset billing master meter metering point; wherein, the meter code information includes at least the last meter code value and the time information corresponding to the value;

[0028] The type determination module is used to determine whether the time corresponding to the last meter code information is within the time range of the current line loss calculation cycle based on the last meter code information. When the time corresponding to the meter code information is within the time range of the current line loss calculation cycle, the module compares the bureau code of the starting point of the current line loss calculation cycle with the meter bureau code of the first day of the following month of the current line loss calculation cycle, using the billing master meter point as the benchmark. Based on the comparison result, the module determines the type of meter code information to be converted and included.

[0031] If the meter is in a canceled or deactivated state, determine whether the meter's settlement electricity for this line loss calculation period is not 0;

[0032] If the settlement electricity of the meter in this line loss calculation period is 0, then mark the meter electricity as 0;

[0033] When the meter is not in a deactivated or out-of-use state, or when the settlement electricity of the meter in this line loss calculation period is not 0, the type of meter code information to be converted and included is determined by comparing the circuit code at the beginning of this line loss calculation period with the circuit code of the meter on the first day of the following month of the month in which this line loss calculation period is located.

[0034] Preferably, the type determination module is specifically used to calculate and include the meter replacement electricity amount when the circuit code at the start of the current line loss calculation cycle is different from the meter circuit code on the first day of the month following the month in which the current line loss calculation cycle is located.

[0035] When the bureau code of the starting point of this line loss calculation period is the same as the meter bureau code of the first day of the following month of the month in which this line loss calculation period is located, determine whether the meter is in the reporting or new process within this month.

[0036] When a meter is in the reporting or addition process this month, the electricity consumption is converted and included as a reporting or addition of a meter.

[0037] When the meter is not in the reporting or new process this month, determine whether the meter has been deactivated or cancelled in the current line loss calculation period.

[0038] When the meter is out of service or has a user cancellation process during the current line loss calculation period, the electricity consumption reported for outage or cancellation will be converted and included in the calculation.

[0039] When the meter has not been deactivated or cancelled during the current line loss calculation period, extract the longest time span (starting and ending codes) of the meter in the metering master station within the current line loss calculation period.

[0040] Preferably, the line loss-converted power consumption calculation module calculates the metered power consumption according to the following calculation model:

[0041] Metered electricity consumption = (minimum - minimum) multiplied by the multiplier / time span of minimum and minimum * time span of the line loss cycle.

[0042] In summary, implementing the embodiments of the present invention has the following beneficial effects:

[0043] This invention provides a method and system for calculating the equivalent electricity consumption for concurrent comprehensive line loss. It calculates and includes the electricity consumption based on the starting and ending points of the longest time period (exceeding 3 / 4 of the line loss calculation period) obtained by the meter within the concurrent line loss calculation cycle. This addresses the problem that electricity consumption by users often varies across dates, making accurate calculation difficult and consequently hindering the accuracy of concurrent comprehensive line loss values. Furthermore, it employs a method that combines business categories with business information from the marketing system and meter readings from the metering master station to classify and calculate the equivalent electricity consumption.

Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, obtaining other drawings based on these drawings without creative effort still falls within the scope of the present invention.

[0045] Figure 1 This is a schematic diagram of the main flow of a method for calculating the equivalent electricity of synchronous comprehensive line loss in an embodiment of the present invention.

[0046] Figure 2 This is a schematic diagram of a system for calculating the equivalent electricity consumption based on the synchronous comprehensive line loss in an embodiment of the present invention. Detailed Implementation

[0047] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings.

[0048] like Figure 1 The diagram shown is a schematic representation of an embodiment of a method for calculating the equivalent electricity consumption based on concurrent comprehensive line loss provided by the present invention. In this embodiment, the method includes the following steps:

[0049] Obtain the last meter code information from the meter code library under the preset billing master meter metering point, wherein the meter code information includes at least the last meter code value and the time information corresponding to the value; that is, extract the last meter code from the meter code library under each billing master meter metering point; determine whether the month corresponding to the extracted meter code is within the month of the current line loss calculation cycle.

[0050] Furthermore, based on the last meter code information, it is determined whether the time corresponding to the meter code information is within the time range of the current line loss calculation cycle;

[0051] In a specific embodiment, when the time corresponding to the meter code information is not within the time range of the current line loss calculation cycle, it is determined whether the meter is in a canceled or disabled state.

[0052] If the meter is in a deactivated or out-of-use state, determine whether the meter's settlement electricity for this line loss calculation period is not 0; if the meter's settlement electricity for this line loss calculation period is 0, mark the meter's electricity as 0.

[0053] When the meter is not in a closed or deactivated state, or when the meter's settlement electricity volume for the current line loss calculation period is not zero, the type of meter code information to be converted and included is determined by comparing the meter code at the start of the current line loss calculation period with the meter code on the first day of the following month of the month in which the current line loss calculation period falls. That is, whether the month corresponding to the extracted meter code is within the current line loss calculation period; if not, proceed to the next step; if so, compare the current line loss calculation period; then determine whether the meter is in a closed or deactivated state; if not, compare the current line loss calculation period; if so, proceed to the next step; then determine whether the meter's settlement electricity volume for the current line loss calculation period is not zero; if not, the meter's electricity volume is zero; if so, proceed to the next step.

[0054] Furthermore, when the time corresponding to the meter code information falls within the time range of the current line loss calculation period, the billing master meter point is used as the benchmark. The bureau code at the beginning of the current line loss calculation period is compared with the meter bureau code on the first day of the following month of the current line loss calculation period. Based on the comparison result, the type of meter code information is converted and included.

[0055] In a specific embodiment, when the meter code at the start of the current line loss calculation period differs from the meter code on the first day of the following month of the month in which the current line loss calculation period falls, it is included in the meter replacement electricity calculation. When the meter code at the start of the current line loss calculation period is the same as the meter code on the first day of the following month of the month in which the current line loss calculation period falls, it is determined whether the meter is in the reporting or addition process within this month. Understandably, based on the metering point, the meter code at the start of the current line loss calculation period and the meter code on the 1st of the following month of the month in which the current line loss calculation period falls are compared. It is determined whether the two meter codes are the same; if not, the meter replacement electricity calculation is included; if so, proceed to the next step.

[0056] Specifically, when a meter is in the reporting or addition process this month, the electricity consumption is calculated and included as a reported or added meter. When a meter is not in the reporting or addition process this month, it is determined whether the meter has been deactivated or cancelled during the current line loss calculation period. Understandably, it is determined whether the meter is in the reporting or addition process this month. If not, proceed to the next step; if so, the electricity consumption of the reported or added meter is calculated and included.

[0057] Specifically, when a meter has a shutdown or account cancellation process within the current line loss calculation period, the electricity consumption reported for shutdown or account cancellation is included in the calculation. When a meter does not have a shutdown or account cancellation process within the current line loss calculation period, the longest time span (starting and ending times) of the meter in the metering master station within the current line loss calculation period is extracted. In essence, it determines whether the meter has a shutdown or account cancellation process within the current line loss calculation period. If not, proceed to the next step; if so, the electricity consumption reported for shutdown or account cancellation is included in the calculation.

[0058] Furthermore, once the type of meter code information is determined, the starting and ending codes with the longest time span within the current line loss calculation period are extracted from the metering master station.

[0059] Furthermore, it is determined whether the ratio between the time span of the minimum and the end time intervals and the current line loss calculation period is greater than a preset judgment standard value; if not, the most recent settlement electricity volume from the marketing system is used for calculation; if so, the equivalent electricity volume for the same period's comprehensive line loss is calculated according to a preset calculation model. In specific implementation, it is determined whether this time span exceeds 75% of the time span of the line loss calculation period, and the electricity volume obtained from the minimum and end time intervals of the longest period within the same period's line loss calculation period with a time span exceeding 3 / 4 of the line loss calculation period is used for calculation.

[0060] Specifically, the calculation model based on the preset formula is: Metered electricity consumption = (Minimum - Maximum) × Multiplier / Time span between Minimum and Maximum * Time span of the line loss cycle. Whether this time span exceeds 75% of the line loss calculation cycle's time span is determined. If not, the most recent settlement electricity consumption from the marketing system is used for calculation. If so, Metered electricity consumption = (Minimum - Maximum) × Multiplier / Time span between Minimum and Maximum * Time span of the line loss cycle.

[0061] like Figure 2 As shown, the present invention also provides a calculation system for the equivalent electricity consumption of simultaneous comprehensive line loss, used to implement the method described, characterized in that it includes:

[0062] The information acquisition module is used to acquire the last meter code information in the meter code library under the preset billing master meter metering point; wherein, the meter code information includes at least the last meter code value and the time information corresponding to the value;

[0063] The type determination module is used to determine whether the time corresponding to the last meter code information is within the time range of the current line loss calculation cycle based on the last meter code information. When the time corresponding to the meter code information is within the time range of the current line loss calculation cycle, the module compares the bureau code of the starting point of the current line loss calculation cycle with the meter bureau code of the first day of the following month of the current line loss calculation cycle, using the billing master meter point as the benchmark. Based on the comparison result, the module determines the type of meter code information to be converted and included.

[0064] The line loss conversion electricity calculation module is used to extract the longest time span (starting and ending codes) of the meter in the metering master station within the current line loss calculation period after determining the type of conversion of the meter code information; determine whether the ratio between the time span of the starting and ending codes and the current line loss calculation period is greater than a preset judgment standard value; if not, the most recent settlement electricity from the marketing system is used for conversion; if so, the comprehensive line loss conversion electricity for the same period is calculated according to the preset calculation model.

[0065] In a specific embodiment, the type determination module is specifically used to determine whether the meter is in a deactivated or disabled state when the time corresponding to the meter code information is not within the time range of the current line loss calculation cycle.

[0066] If the meter is in a canceled or deactivated state, determine whether the meter's settlement electricity for this line loss calculation period is not 0;

[0067] If the settlement electricity of the meter in this line loss calculation period is 0, then mark the meter electricity as 0;

[0068] When the meter is not in a deactivated or out-of-use state, or when the settlement electricity of the meter in this line loss calculation period is not 0, the type of meter code information to be converted and included is determined by comparing the circuit code at the beginning of this line loss calculation period with the circuit code of the meter on the first day of the following month of the month in which this line loss calculation period is located.

[0069] In this embodiment, the type determination module is specifically used to calculate and include the meter replacement electricity volume when the bureau code at the start of the current line loss calculation cycle is different from the meter bureau code on the first day of the month following the month in which the current line loss calculation cycle is located.

[0070] When the bureau code of the starting point of this line loss calculation period is the same as the meter bureau code of the first day of the following month of the month in which this line loss calculation period is located, determine whether the meter is in the reporting or new process within this month.

[0071] When a meter is in the reporting or addition process this month, the electricity consumption is converted and included as a reporting or addition of a meter.

[0072] When the meter is not in the reporting or new process this month, determine whether the meter has been deactivated or cancelled in the current line loss calculation period.

[0073] When the meter is out of service or has a user cancellation process during the current line loss calculation period, the electricity consumption reported for outage or cancellation will be converted and included in the calculation.

[0074] When the meter has not been deactivated or cancelled during the current line loss calculation period, extract the longest time span (starting and ending codes) of the meter in the metering master station within the current line loss calculation period.

[0075] Specifically, the line loss-converted power consumption calculation module calculates the metered power consumption according to the following calculation model:

[0076] Metered electricity consumption = (minimum - minimum) multiplied by the multiplier / time span of minimum and minimum * time span of the line loss cycle.

[0077] It should be noted that the system described in the above embodiments corresponds to the method described in the above embodiments.
