Description

Technical Field

[0001] The present invention relates to power system technologies, and in particular to a method and device for electricity quantity retroactive compensation, a computer device, and a computer-readable storage medium. Background Art

[0002] The stability and reliability of electricity quantity calculation are directly related to the economic benefits of the entire power industry. Therefore, the power industry has increasingly high requirements for the accuracy of electricity quantity calculation.

[0003] Currently, affected by the nature of user loads and actual electricity consumption, the three-phase loads of the vast majority of users are asymmetric. In the past, for a symmetric three-phase circuit with a three-phase four-wire connection method, when a single-phase complete voltage loss or complete current loss occurs, the electricity meter reading of a single voltage-loss or current-loss phase is retroactively compensated by using the method of "retroactive compensation of electricity meter reading = 1 / 2 * electricity meter reading during the fault period"; when two-phase complete voltage loss or complete current loss occurs, the electricity meter readings of two voltage-loss or current-loss phases are retroactively compensated by using the method of "retroactive compensation of electricity meter reading = 2 * electricity meter reading during the fault period". There is no unified calculation method for retroactive compensation calculation of voltage loss and current loss in other cases.

[0004] The method of directly multiplying the retroactive compensation coefficient such as 1 / 2 or 2 by the electricity meter reading during the fault period has the following deficiencies: First, this method can only be applied to special cases of complete voltage loss or complete current loss. Since the reasons for voltage loss or current loss are diverse, the possibility of complete voltage loss or complete current loss is relatively large when there is a disconnection point in the metering secondary wiring or the metal contact part is burned out. However, in the vast majority of cases, the degree of voltage loss or current loss is incomplete. Therefore, using this method for retroactive compensation will result in a situation where the retroactively compensated electricity quantity is greater than the actual electricity quantity to be retroactively compensated. Second, affected by the nature of the load, the actual electricity consumption circuit model of the user is an asymmetric three-phase circuit, and it is difficult to calculate using the retroactive compensation coefficient of the symmetric three-phase circuit model, and the calculation result is difficult to be persuasive. Third, for the model of an asymmetric three-phase circuit, there is a lack of a general calculation method for retroactive compensation of electricity quantity. Summary of the Invention

[0005] A method, device, computer device, and computer-readable storage medium for retroactive compensation of electricity quantity provided by an embodiment of the present invention are used to realize retroactive compensation of electricity quantity applicable to cases of complete voltage loss or current loss, incomplete voltage loss or current loss, and asymmetric three-phase circuits, expand the applicable range of retroactive compensation of electricity quantity, be more in line with the actual electricity consumption situation, and the retroactively compensated electricity quantity can exclude the electricity quantity already recorded in the electricity meter during incomplete voltage loss or incomplete current loss.

[0032] Embodiment 1

[0033] Figure 1 FIG. 1 is a flowchart of a power quantity supplementary method provided for Embodiment 1 of the present invention. This embodiment is applicable to supplementary power quantity under different circumstances to improve the accuracy and reliability of power quantity measurement. This method can be executed by a power quantity supplementary device, which can be implemented in the form of hardware and / or software, and the power quantity supplementary device can be configured in a computer device, such as installed in a desktop computer or a workbench. As Figure 1 shown, the method includes:

[0034] S101. Obtain the proportion of the power parameter values of each phase of the faulty electric meter before the fault occurs.

[0035] Specifically, for an electric energy meter with a three-phase four-wire connection method, its internal power is the sum of the powers of three elements. The three elements refer to the elements that respectively measure the voltage, current and power factor angle of phase A, phase B and phase C.

[0036] Exemplarily, since the actual power during the fault period is the area sum of the instantaneous powers at each infinitesimal moment, and the period of the actual power recorded by the meter reading terminal in practical applications is 15 minutes, the actual power curve is simulated by the instantaneous power broken line graph every 15 minutes. First, a large number of instantaneous powers are plotted on the coordinate axis and connected into a broken line graph with straight lines. By obtaining the ratio of the area of each phase broken line graph to the total area, the corresponding proportion of the three-phase power quantity before the fault is obtained. Power can include active power, that is, the voltage and current are in the same phase, the power supply supplies power to the load, and the load converts electrical energy into other energies. Power can also include reactive power, that is, the part where the voltage and current are out of phase. Electrical energy is exchanged between the power supply and the load, and this part of electrical energy (except for line losses) is not converted into other energies (other than electromagnetic).

[0037] Exemplarily, the proportion of the power parameter values of each phase of the faulty electricity meter before the fault is the ratio of the power of each phase to the sum of the powers of all phases. The active power of each phase of the faulty electricity meter before the fault can be represented by P A正常 、P B正常 、P C正常 ; the reactive power of each phase can be represented by Q A正常 、Q B正常 、Q C正常 . The proportion of the active power parameter values of each phase can be represented by KP A正常 、KP B正常 、KP C正常 ; the proportion of the reactive power parameter values of each phase can be represented by KQ A正常 、KQ B正常 、KQ C正常 . Therefore, the proportions of the power parameter values of each phase of the faulty electricity meter before the fault are respectively:

[0038]

[0039]

[0040]

[0041] S102. Obtain the proportion of the power parameter values of each phase of the faulty electricity meter during the fault.

[0042] Exemplarily, the proportion of the power parameter values of each phase of the faulty electricity meter during the fault is the ratio of the power of each phase to the sum of the powers of all phases. The active power of each phase of the faulty electricity meter during the fault can be represented by P A故障 、P B故障 、P C故障 ; the reactive power of each phase can be represented by Q A故障 、Q B故障 、Q C故障 . The proportion of the active power parameter values of each phase can be represented by KP A故障 、KP B故障 、KP C故障 ; the proportion of the reactive power parameter values of each phase can be represented by KQ A故障 、KQ B故障 、KQ C故障 . Therefore, the proportions of the power parameter values of each phase of the faulty electricity meter during the fault are respectively:

[0043]

[0044]

[0045]

[0046] S103. Obtain the electricity consumption of the faulty electricity meter during the fault period.

[0047] Specifically, since the actual power during the fault period is the sum of the instantaneous power areas at each infinitesimal moment, and the period for the actual application of the meter reading terminal to record the instantaneous power is 15 minutes, the actual power curve is simulated using the instantaneous power broken line graph every 15 minutes, and the electricity consumption of the faulty meter during the fault period can be obtained by calculating the area of the broken line graph.

[0048] Exemplarily, the active electricity consumption can be represented by W P and the reactive electricity consumption can be represented by W Q . Export the meter reading during the fault period in the "meter reading" application module in the metering automation system to obtain the electricity consumption of the faulty meter. Among them, W P is the difference between the forward active meter reading at the moment of fault recovery and the forward active meter reading at the start of the fault; W Q is the difference between the combined reactive meter reading at the moment of fault recovery and the combined reactive meter reading at the start of the fault. The metering automation system can transmit the user electricity consumption data in the meter reading terminal to the background. The meter reading is the number displayed in a row of windows on the meter dial, which is used to indicate the cumulative electricity consumption of the customer. The forward active meter reading refers to the output of forward active electric energy, and the combined reactive meter reading is obtained by performing addition and subtraction combination operations on the reactive electric energy in any four quadrants.

[0049] S104. Obtain the supplementary electricity consumption according to the proportion of the power parameter values of each phase of the electricity meter before the fault, the proportion of the power parameter values of each phase of the electricity meter during the fault, and the electricity consumption of the faulty meter.

[0050] Specifically, the supplementary electricity consumption corresponding to the active electricity consumption W P and the reactive electricity consumption W Q is W P追补 and W Q追补 .

[0051] Exemplarily, taking the A-phase fault as an example, when there is a single-phase complete current loss or voltage loss, the supplementary electricity consumption is respectively expressed as:

[0052]

[0053]

[0054] Exemplarily, taking the A-phase fault as an example, when there is a single-phase incomplete current loss or voltage loss, the supplementary electricity consumption is respectively expressed as:

[0055]

[0056]

[0057] Exemplarily, taking the faults of phase A and phase B as examples, when there is a complete loss of current or voltage in two phases, the supplementary electricity quantities are respectively expressed as:

[0058]

[0059]

[0060] Exemplarily, taking the faults of phase A and phase B as examples, when there is an incomplete loss of current or voltage in two phases, the supplementary electricity quantities are respectively expressed as:

[0061]

[0062]

[0063] A method for supplementary electricity quantity provided by an embodiment of the present invention obtains the proportion of power parameter values of each phase of a faulty electricity meter before the fault occurs, obtains the proportion of power parameter values of each phase of the faulty electricity meter during the fault occurs, obtains the electricity quantity of the faulty meter during the fault occurs, and obtains the supplementary electricity quantity according to the proportion of power parameter values of each phase of the electricity meter before the fault occurs, the proportion of power parameter values of each phase of the electricity meter during the fault occurs, and the electricity quantity of the faulty meter. By adopting the above technical solution, it can be applicable to the supplementary electricity quantity of complete voltage loss or current loss, incomplete voltage loss or current loss, and asymmetric three-phase circuit conditions, and a set of general supplementary electricity quantity calculation formulas are formed, expanding the applicable range, being more in line with the actual electricity consumption situation, and the supplementary electricity quantity can exclude the electricity quantity already recorded in the meter during incomplete voltage loss or incomplete current loss.

The active power P and reactive power Q of each element are respectively the product of the trigonometric function values of the corresponding phase voltage U, current I, and power factor angle θ, that is

[0068] P = U * I * cosθ Q = U * I * sinθ

[0069] Exemplarily, the electrical energy data (including three-phase voltage, current, power factor angle θ, etc.) collected every 15 minutes for a period of time before the fault is exported through the "load" application module of the metering automation system. Then, the instantaneous power of each phase collected every 15 minutes is the first instantaneous power, which can be respectively expressed as:

[0074] Among them, the first time period refers to the time period before the fault of the electricity meter when the fault occurs. It should be noted that since the period for the meter reading terminal to record the instantaneous power is 15 minutes, the first time period can be expressed as 15*N, where N is the number of periods of the instantaneous power recorded by the meter reading terminal.

[0075] Exemplarily, assume that the moment when the meter reading terminal starts to read the meter for the first time before the fault is t 0 ,and the moment when the electricity meter fails is t 1 ,the first time period is t 1 -t 0 ,then the electricity quantity of each phase within the first time period can be expressed as:

According to the first instantaneous power, obtain the electricity quantity of each phase within the first time period. According to the ratio of the electricity quantity of the phase to the sum of the electricity quantities of all phases, obtain the proportion of the power parameter values of each phase before the fault occurs. By adopting the above technical solutions, the accuracy and reliability of electricity quantity measurement can be improved.

[0091] Exemplarily, the instantaneous power of each phase collected every 15 minutes during the fault is the second instantaneous power, and the second instantaneous power corresponding to each phase can be respectively expressed as:

[0092] P A故障 = U A故障 * I A故障 * cosθ A故障 ,Q A故障 = U A故障*I A故障 *sinθ A故障 ;

[0093] P B故障 =U B故障 *I B故障 *cosθ B故障 ,Q B故障 =U B故障 *I B故障 *sinθ B故障 ;

[0096] Wherein, the second time period refers to the time period of the faulty electricity meter during the fault. It should be noted that since the period for the meter reading terminal to record the instantaneous power is 15 minutes, the second time period can be expressed as 15*N, where N is the number of periods of the instantaneous power recorded by the meter reading terminal.

[0097] Exemplarily, assume that the moment when the electricity meter fails is t 1 , and the moment of the last meter reading by the meter reading terminal during the fault is t 2 , and the second time period is t 2 -t 1 , then the electricity quantity of each phase within the second time period can be expressed as:
