Description

Technical Field

[0001] Embodiments of the present invention relate to the field of data processing technology, and in particular to a method, device, equipment and storage medium for determining the amount of additional electricity consumed by an electric energy meter. Background Art

[0002] Traditional methods of detecting metering faults of electric energy meters are mainly weekly inspection, initial inspection, meter reading by meter readers, abnormal power calculation, power consumption inspection, etc. This inspection method causes metering faults to last for a long time and cannot be discovered in time, which can easily cause losses to both the power supplier and the user, and even affect safe power supply. With the advancement of technology, metering automation systems can realize real-time collection, monitoring, analysis and processing of metering meter power information, and can quickly find metering faults.

[0003] Although the multi-function electricity meters currently in use have a voltage loss alarm function, they do not have a judgment alarm for abnormally high or low voltage on the electricity meter, nor do they separately store and count the fault time, current, voltage, power, electricity, and the amount of electricity that needs to be replenished. In addition, due to the limited storage space of the electricity meter, the electricity meter stores historical electricity data at intervals of one minute, and the time is generally one year. If the time exceeds, the previous records will be overwritten. If the voltage abnormality is not discovered and handled for a long time, and the storage time period of the electricity meter is exceeded, it is difficult to confirm the exact fault time by using a computer to read the electricity meter data on site, which affects the accurate replenishment of electricity.

[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0031] The metering automation system has the function of analyzing the collected data to determine whether there are any metering anomalies. Since the data is stored in the database, there is no time limit. However, due to the huge number of electricity meters, the current automation system collects electricity meter data at intervals of 15 minutes. If a voltage anomaly occurs within the 15-minute interval and needs to be compensated, the compensation time cannot be accurately determined. If the voltage fluctuates abnormally, only the average value of the voltage data for 15 minutes during the fault period is used to compensate for the electricity, which will also cause errors in the compensated electricity. Moreover, the larger the transformation ratio of the user's transformer, the greater the error. In extreme cases, it will seriously affect the accuracy and fairness of the compensated electricity.

[0032] Embodiment 1

[0033] Figure 1 This is a flow chart of a method for determining the amount of electricity to be replenished by an electric energy meter provided in the first embodiment of the present invention. This embodiment is applicable to the case of determining the amount of electricity to be replenished during a fault period. The method can be executed by a device for determining the amount of electricity to be replenished by an electric energy meter. The device can be implemented in the form of software and / or hardware. Optionally, it can be implemented by an electronic device, which can be a mobile terminal, a PC, or a server. Specifically, it includes the following steps:

[0034] S110, collecting first electric energy data of the electric energy meter at first preset time intervals.

[0035] The first electric energy data includes the voltage, current, power and power of the three phases. The first preset time may be a pre-set time period, such as 15 minutes, 30 minutes, etc., and the first preset time is not limited here. The three phases may include phase A, phase B and phase C, and the power may be the power generated within the first preset time.

[0036] S120, when it is determined according to the three-phase current that the electric energy meter is in a working state, obtaining the connection type of the electric energy meter.

[0037] Among them, the wiring types include the following three types: three-phase three-wire, three-phase four-wire high supply and high metering, and three-phase four-wire high supply and low metering. The method of determining whether the electric energy meter is in a working state based on the current of the three phases can be: compare the current of each phase with the rated current of a set ratio, and determine whether the electric energy meter is in a working state based on the comparison result. Among them, the set ratio can be 0.5%. Specifically, if the current of each phase is greater than 0.5% of the rated current, it indicates that the electric energy meter is in a working state. If the current of one phase is less than or equal to 0.5% of the rated current, it indicates that the electric energy meter is in a non-working state.

[0038] S130: If the voltage in a set number of consecutive first electric energy data meets the abnormal condition corresponding to the wiring type, it is determined that the voltage of the electric energy meter is abnormal during the fault period.

[0039] Among them, the fault period is the period in which the first electric energy data of a continuous set number is collected. The set number is preset, for example, it can be 8. In this embodiment, if the wiring type is three-phase three-wire, the abnormal condition is: the absolute value of the difference between the A phase voltage and the C phase voltage is greater than or equal to the first set value; if the wiring type is three-phase four-wire high supply and high metering, the abnormal condition is: the maximum value of the A phase voltage, the B phase voltage and the C phase voltage is greater than the second set value, and the absolute value of the difference between the smaller two phase voltages is greater than the third set value; if the wiring type is three-phase four-wire high supply and low metering, the abnormal condition is: the maximum value of the A phase voltage, the B phase voltage and the C phase voltage is greater than the fourth set value, and the absolute value of the difference between the smaller two phase voltages is greater than the fifth set value.

[0040] Among them, the first set value can be set to 2V, the second set value can be set to 55V, the third set value can be set to 5V, the fourth set value can be set to 210V, and the fifth set value can be set to 20V.

[0041] Specifically, when the connection type of the electric energy meter is three-phase three-wire, if the voltages in the eight first electric energy data collected continuously all meet the following conditions: the absolute value of the difference between the A-phase voltage and the C-phase voltage is greater than or equal to 2V, then the electric energy meter is determined to have abnormal voltage during the fault period, otherwise, the electric energy meter has no voltage abnormality. When the connection type of the electric energy meter is three-phase four-wire high supply and high timing, if the voltages in the eight first electric energy data collected continuously all meet the following conditions: the maximum value of the A-phase voltage, the B-phase voltage and the C-phase voltage is greater than 55V, and the absolute value of the difference between the two smaller phase voltages is greater than 5V, then the electric energy meter is determined to have abnormal voltage during the fault period, otherwise, the electric energy meter has no voltage abnormality. When the connection type of the electric energy meter is three-phase four-wire high supply and low timing, if the voltages in the eight continuously collected first electric energy data all meet the following conditions: the maximum value of the A phase voltage, the B phase voltage and the C phase voltage is greater than 210V, and the absolute value of the difference between the two smaller phase voltages is greater than 20V, then it is determined that the voltage of the electric energy meter is abnormal during the fault period; otherwise, the electric energy meter has no voltage abnormality.

[0042] S140, determining an abnormality level according to the voltage and current in each first electric energy data within the fault period.

[0043] The abnormal level may include a red level and a yellow level, and the red level is higher than the yellow level. Specifically, the abnormal level may be determined according to the voltage and current in each first electric energy data during the fault period: judging whether the voltage of each phase and the current of each phase during the fault period meet the second abnormal condition corresponding to the wiring type; if the second abnormal condition corresponding to the wiring type is met, the abnormal level is a red level; if the second abnormal condition corresponding to the wiring type is not met, the abnormal level is a yellow level.

[0044] In this embodiment, if the wiring type of the electric energy meter is three-phase three-wire, the second abnormal condition is: the A-phase electric energy data in 8 consecutive first electric energy data all meet the following conditions: the voltage is less than a certain proportion (such as 78%) of the rated voltage and the current is not equal to 0; or, the C-phase electric energy data in 8 consecutive first electric energy data all meet the following conditions: the voltage is less than a certain proportion (such as 78%) of the rated voltage and the current is not equal to 0, then it is determined that the C-phase voltage is undervoltage. If the wiring type of the electric energy meter is three-phase four-wire (high supply and high metering or high supply and low metering), the second abnormal condition is: the A-phase electric energy data in 8 consecutive first electric energy data all meet the following conditions: the voltage is less than a certain proportion (such as 78%) of the rated voltage and the current is not equal to 0; or, the B-phase electric energy data in 8 consecutive first electric energy data all meet the following conditions: the voltage is less than a certain proportion (such as 78%) of the rated voltage and the current is not equal to 0; or, the C-phase electric energy data in 8 consecutive first electric energy data all meet the following conditions: the voltage is less than a certain proportion (such as 78%) of the rated voltage and the current is not equal to 0.

[0045] In this embodiment, when a phase meets the second abnormal condition during the fault period, it is determined that the phase has voltage loss, and a red level alarm message is generated, which includes: the phase where the voltage loss occurs, the specific time of occurrence, and the average voltage of the phase. If any phase does not meet the second abnormal condition, a yellow level alarm message is generated, and the alarm message includes: the unstable voltage of the electric energy meter, the time of occurrence, and the average voltage of each phase.

[0046] S150, determining a first compensatory electric quantity, a second compensatory electric quantity and a third compensatory electric quantity of the electric energy meter during a fault period.

[0047] The first replenishment power is determined based on preset fault data, the second replenishment power is determined based on a set number of consecutive first electric energy data, and the third replenishment power is determined based on the power of the electric energy meter in a historical normal period corresponding to the fault period.

[0048] The preset fault data is obtained by statistically analyzing the sub-fault data acquired every second preset time.

[0049] Specifically, the preset fault data is obtained in the following manner: collecting the second electric energy data of the electric energy meter at every second preset time; when the electric energy meter is determined to be in a working state based on the three-phase current, judging whether a voltage abnormality occurs in the electric energy meter based on the three-phase voltage and the rated voltage; if a voltage abnormality occurs in the electric energy meter, determining the amount of compensatory power within the current second preset time based on the second electric energy data, and storing the second electric energy data and the compensatory power as sub-fault data in the first data table; processing the sub-fault data in the first data table at every first preset time to obtain preset fault data, and storing the preset fault data in the second data table; wherein the preset fault data includes average voltage, average current, average power and accumulated compensatory power.

[0050] Among them, the second electric energy data includes the voltage, current, power and electricity of the three phases, and the second preset time is less than the first preset time. Exemplarily, assuming that the first preset time is set to 15 minutes, the first preset time can be set to 1 minute. Specifically, the method of determining whether the electric energy meter is in a working state according to the current of the three phases can be: comparing the current of each phase with the rated current of a set ratio, and determining whether the electric energy meter is in a working state according to the comparison result. Among them, the set ratio can be 0.5%. Specifically, if the current of each phase is greater than 0.5% of the rated current, it indicates that the electric energy meter is in a working state. If the current of one phase is less than or equal to 0.5% of the rated current, it indicates that the electric energy meter is in a non-working state.

[0051] In this embodiment, the method for judging whether the electric energy meter is faulty based on the three-phase voltage and the rated voltage can be: if the three-phase voltages are all greater than or equal to a first proportion of the rated voltage (which can be set to 95%), then the electric energy meter has no voltage abnormality; if at least one of the three-phase voltages is less than the first proportion of the rated voltage, then the electric energy meter has a voltage abnormality.

[0052] In this embodiment, if a voltage abnormality occurs in the electric energy meter, the method for determining the amount of compensatory electricity within the current second preset time based on the second electric energy data can be: if the voltage of the current phase is less than the first voltage threshold and greater than or equal to the second voltage threshold, the main compensatory electricity amount is determined based on the voltage of the current phase, the rated voltage, the power of the current phase and the second preset time; if the voltage of the current phase is less than the second voltage threshold, the correction coefficient is determined based on the rated power and the power of the current phase; the compensatory electricity amount is determined based on the correction coefficient and the electricity of the current phase.

[0053] The first voltage threshold and the second voltage threshold are determined by the rated voltage. For example, the first voltage threshold may be a first proportion (95%) of the rated voltage, and the second voltage threshold may be a second proportion (60%) of the rated voltage. When the voltage of each phase in the three phases is less than the first voltage threshold and greater than or equal to the second voltage threshold, the formula for determining the main compensation amount based on the voltage of the phase, the rated voltage, the power of the phase and the second preset time can be expressed as: W 追补 =P 本相 *(Un-U 本相 ) / U 本相 *t, where W 追补 To make up for the power, P 本相 is the current phase power, Un is the rated power, U 本相 is the phase voltage, and t is the second preset time. If the phase voltage is less than the second voltage threshold, the calculation formula for determining the correction coefficient based on the rated power and the phase power can be expressed as: K = Pu / P 本相 , where Pu is the rated power, P 本相 The calculation formula for determining the supplementary power based on the correction coefficient and the power of the current phase can be expressed as: W 追补 =(K-1)×electricity.

[0054] In this embodiment, after the replenishment power of each phase is determined, the voltage, current, power, power and replenishment power of each item in the second electric energy data are stored as a sub-fault data in the first data table.

[0055] In this embodiment, after obtaining the first data table, statistics are collected on the sub-fault data in the first data table at intervals of the first preset time, and the average voltage, average current, average power and accumulated replenishment power of each phase within the first preset time are obtained. The number of sub-fault data included in the first preset time is counted, thereby obtaining preset fault data, and the preset fault data is stored in the second data table.

[0056] Optionally, in order to accurately warn of faults, when an abnormal voltage occurs in the electric energy meter, the fault can be graded according to the voltage value. Figure 2 is an example diagram of generating sub-fault data in this embodiment, such as Figure 2 As shown, the process includes the following steps:

[0057] S201, collecting second electric energy data of the electric energy meter at second preset time intervals.

[0058] S202, determine whether the current of each phase is greater than 0.5% of the rated current. If so, the electric energy meter is in working state, and then execute S203; if not, the electric energy meter is in non-working state.

[0059] S203, determine whether the voltage of each phase is less than 95% of the rated voltage. If not, the electric energy meter has no voltage abnormality. If yes, the electric energy meter has a voltage abnormality, and execute S204.

[0060] S204, determine whether the voltage of each phase is less than 90% of the rated voltage, if not, execute S205; if yes, execute S206.

[0061] S205, generating a yellow voltage abnormality warning, and determining the current compensatory power within the second preset time in a first manner, and storing the second electric energy data and the compensatory power as sub-fault data in a first data table.

[0062] S206, determine whether the voltage of each phase is less than 78% of the rated voltage, if not, execute S207, if yes, execute S208.

[0063] S207, generating an orange voltage abnormality warning, and determining the current compensatory power within the second preset time in a first manner, and storing the second electric energy data and the compensatory power as sub-fault data in a first data table.

[0064] S208, determine whether the voltage of each phase is less than 60% of the rated voltage, if not, execute S209; if yes, execute S210.

[0065] S209, generating a red voltage abnormality warning, and determining the current compensatory power within the second preset time in a first manner, and storing the second electric energy data and the compensatory power as sub-fault data in a first data table.

[0066] S210, generating a red voltage abnormality warning, and determining the amount of replenishment power within the current second preset time in a second manner, and storing the second electric energy data and the amount of replenishment power as sub-fault data in a first data table.

[0067] The first method is to determine the main compensation amount based on the current phase voltage, the rated voltage, the current phase power and the second preset time. The second method is to determine the correction coefficient based on the rated power and the current phase power; and determine the compensation amount based on the correction coefficient and the current phase power.

[0068] Specifically, after obtaining the preset fault data, the accumulated replenishment power in the preset fault data in the second data table that falls within the fault period is accumulated to obtain the first replenishment power. The second replenishment power is calculated by accumulating the replenishment power corresponding to the first power data of a set number of consecutive times within the fault period. The calculation formula of the replenishment power corresponding to the first power data can be expressed as: W 追补 =P 本相 *(Un-U 本相 ) / U 本相 *T, where W 追补 To make up for the power, P 本相 is the current phase power, Un is the rated power, U 本相 is the phase voltage, and T is the first preset time. The third replenishment power may be determined by subtracting the power of the electric energy meter in the historical normal period corresponding to the fault period from the power in the fault period to obtain the third replenishment power.

[0069] S150, determining a target supplementary power of the electric energy meter according to the abnormality level, the first supplementary power, the second supplementary power and the third supplementary power.

[0070] In this embodiment, the method of determining the target replenishment power is different according to the abnormality level.

[0071] Optionally, the method of determining the target compensatory power of the electric energy meter according to the abnormal level, the first compensatory power, the second compensatory power and the third compensatory power may be: if the abnormal level is the yellow level, then determining the ratio of the difference between the first compensatory power and the second compensatory power to the second compensatory power; if the absolute value of the ratio is less than the set ratio, then determining the first compensatory power as the target compensatory power; if the absolute value of the ratio is greater than or equal to the set ratio, then determining the ratio of the difference between the first compensatory power and the third compensatory power to the third compensatory power; if the ratio is less than the set ratio, then determining the first compensatory power as the target compensatory power; if the ratio is greater than or equal to the set ratio, then determining the third compensatory power as the target compensatory power.

[0072] The set ratio can be set to 10%, and the difference between the first and second supplementary power and the ratio of the second supplementary power can be expressed as: (W1-W2) / W2. The difference between the first and third supplementary power and the ratio of the third supplementary power can be expressed as: (W1-W3) / W3.

[0073] Optionally, the method of determining the target catch-up power of the electric energy meter based on the connection type, the first catch-up power, the second catch-up power and the third catch-up power can be: if the abnormality level is a red level, then determining the ratio of the difference between the first catch-up power and the third catch-up power and the third catch-up power; if the ratio is less than a set ratio, then determining the first catch-up power as the target catch-up power; if the ratio is greater than or equal to the set ratio, then determining the third catch-up power as the target catch-up power.

[0074] Among them, the setting ratio can be set to 10%.

[0075] For example, Figure 3 is a flow chart for determining the target replenishment power in this embodiment, such as Figure 3 As shown, the process includes the following steps:

[0076] S301, determine the abnormal level according to the voltage and current in each first electric energy data within the fault period, if it is a yellow level, execute S302, if it is a red level, execute S304.

[0077] S302: Determine a ratio of a difference between the first supplementary power and the second supplementary power to the second supplementary power.

[0078] S303, determine whether the absolute value of the ratio is less than 10%, if not, execute S304, if yes, execute S306.

[0079] S304: Determine a ratio of a difference between the first supplementary power and the third supplementary power to the third supplementary power.

[0080] S305, determine whether the absolute value of the ratio is less than 10%, if so, execute S306, if not, execute S307.

[0081] S306: Determine the first supplementary electric power as the target supplementary electric power.

[0082] S307: The third supplementary electric power is determined as the target supplementary electric power.

[0083] The technical solution of this embodiment is to collect the first electric energy data of the electric energy meter at a first preset time interval; wherein the first electric energy data includes the voltage, current, power and electricity of the three phases; when the electric energy meter is determined to be in a working state according to the current of the three phases, the wiring type of the electric energy meter is obtained; wherein the wiring types include the following three types: three-phase three-wire, three-phase four-wire high supply and high meter, and three-phase four-wire high supply and low meter; if the voltage in the first electric energy data of a continuous set number meets the abnormal condition corresponding to the wiring type, it is determined that the voltage of the electric energy meter is abnormal during the fault period; wherein the fault period is the period during which the voltage of the first electric energy data of a continuous set number is collected.
