Description

Technical Field

[0001] This invention relates to the field of electricity meter control technology, and in particular to an adaptive control method, medium, and system for a wide-range electricity meter. Background Technology

[0002] Electricity meters are used not only to measure users' electricity consumption, collect data, remotely monitor, dispatch power, and manage energy, but also to monitor users' electricity consumption behavior in real time and record detailed electricity data. As the core equipment for electricity metering, the accuracy and precision of electricity meters directly affect several key areas such as energy distribution, economic transactions, and energy conservation and emission reduction.

[0003] In practical applications, electricity meters are prone to errors due to various factors. These error sources include those caused by manufacturing processes and material selection, as well as additional errors from environmental factors and load variations. To ensure accuracy and precision, traditional methods often employ electricity meters with a relatively small measurement range. However, in overseas markets, grid stability varies, the operating environment of electricity meters is more complex, and technical requirements are diverse. Customers exhibit various unstable and changing technical requirements. Therefore, to meet the diverse needs of different customers, it is necessary to develop corresponding meter models for each type of customer to fulfill bidding and supply requirements, which significantly increases research and development and production costs. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: A wide-range energy meter is selected. During its use, the following steps are taken: First, the current current value is acquired, and the corresponding current level value is calculated based on this value. Next, it is determined whether the current current level value matches the execution current level value stored in a register. If not, the electrically erasable programmable read-only memory (EROM) is queried based on the current current level value to obtain the metering parameters corresponding to that value. The metering parameters stored in the register are then corrected based on these parameters, and the execution current level value is updated accordingly. Therefore, by correcting the metering parameters based on real-time current values ​​during the use of a wide-range energy meter, the accuracy of the meter can be guaranteed, its versatility improved, and the research and development and production costs of the meter reduced for complex customer needs.

[0006] Optionally, if the current current level value is consistent with the execution current level value, the metering parameters stored in the register are verified, and if the verification result indicates that the parameters are incorrect, the parameters are corrected based on the data stored in the electrically erasable programmable read-only memory.

[0013] Optionally, the control module is further configured to perform data verification on the metering parameters stored in the register when the current current level value is consistent with the execution current level value stored in the register, and to perform parameter correction based on the data stored in the electrically erasable programmable read-only memory when the data verification result is that the parameter is incorrect.

Detailed Implementation

[0017] To explain in detail the technical principles, specific implementable solutions, possible application scenarios, and achievable objectives and effects of the present invention, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. It is understood that the embodiments described herein and the embodiments shown in the accompanying drawings are only used to more clearly illustrate the technical solutions of the present invention, and are therefore only examples intended to explain the present invention, and should not be construed as limiting the present invention. It should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein.

[0018] In this invention, the range of the electricity meter is set to a wide range. Furthermore, during the use of the wide range electricity meter, the metering parameters are corrected based on the real-time current value, which can ensure the accuracy of the electricity meter, improve the universality of the electricity meter, and thus reduce the research and development and production costs of the electricity meter under complex customer needs.

[0019] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0020] Figure 1 This is a flowchart illustrating an adaptive control method for a wide-range energy meter provided in an embodiment of the present invention. Figure 1 As shown in the figure, an adaptive control method for a wide-range energy meter provided by an embodiment of the present invention includes the following steps: S101: Obtain the current current value and calculate the corresponding current level value based on the current current value.

[0021] In other words, firstly, the correspondence between the current value and the current level value is preset; then, during the use of the wide-range energy meter, the current current value is acquired in real time, and the corresponding current level value is obtained based on the current current value.

[0022] As an example, a wide-range ammeter measures current from 0A to 300A. The current value is then categorized into levels: 0-60A, Cur_level_value is set to 1; 61-120A, Cur_level_value is set to 2; 121-180A, Cur_level_value is set to 3; 181-240A, Cur_level_value is set to 4; and 241-300A, Cur_level_value is set to 5. Thus, after acquiring the current current value in real time, the corresponding current level value can be determined based on that value.

[0023] It should be noted that by dividing the current rating into 5 levels, the current management range of each level can be guaranteed to be 60A, and the multiple from the reference current to the maximum current can be maintained within 12 times (such as the basic current of 5A). This can fully guarantee the linear curve requirements of the energy meter error data, so that the energy meter achieves the best accuracy of error in each level of current range.

[0024] S102, determine whether the current current level value is consistent with the execution current level value stored in the register.

[0025] S103, if not, query the electrically erasable programmable read-only memory according to the current current level value to obtain the metering parameters corresponding to the current current level value, and correct the metering parameters stored in the register based on the metering parameters corresponding to the current current level value, and update the execution current level value according to the current current level value.

[0026] In some specific implementations, if the current current level value is consistent with the execution current level value, the metering parameters stored in the register are verified, and if the verification result indicates that the parameters are incorrect, the parameters are corrected based on the data stored in the electrically erasable programmable read-only memory.

[0027] As a specific example of this embodiment, such as Figure 2 As shown, parameter correction based on the current current value includes the following steps: S201, obtain the current current value, and calculate the corresponding current level value based on the current current value.

[0028] S202, determine whether the current current level value is consistent with the execution current level value stored in the register. If yes, proceed to step S203; otherwise, proceed to step S205.

[0029] S203, perform CRC check on the metering parameters stored in the register; if the check is successful, return to step S201; if the check fails, proceed to step S204.

[0030] S204, Recover the corresponding data from the Electrically Erasable Programmable Read-Only Memory (EEPROM) and return to step S201.

[0031] S205: Query the electrically erasable programmable read-only memory according to the current current level value to obtain the metering parameters corresponding to the current current level value, and correct the metering parameters stored in the register based on the metering parameters corresponding to the current current level value.

[0032] In other words, before the electricity meter leaves the factory, a current of a corresponding range is applied to the electricity meter according to different values ​​of Cur_level_valu. Then, the electricity meter is calibrated within this corresponding current range to ensure that the meter error is normal within this current range. In this way, the metering parameters corresponding to different current level values ​​are stored in an electrically erasable programmable read-only memory.

[0033] S206, Update the execution current level value according to the current current level value, and return to step S201.

[0034] In some specific embodiments, the adaptive control method further includes: querying an electrically erasable programmable read-only memory (EEPROM) based on the current current level value to obtain a voltage compensation parameter table corresponding to the current current level value; obtaining the current voltage value and calculating the corresponding current voltage level value based on the current voltage value; determining whether the current voltage level value is consistent with the execution voltage level value stored in the register; if not, querying the voltage compensation parameter table based on the current voltage level value to obtain the current voltage compensation parameter corresponding to the current voltage level value, correcting the execution voltage compensation parameter stored in the register based on the current voltage compensation parameter corresponding to the current voltage level value, and updating the execution voltage level value based on the current voltage level value.

[0035] As an example, such as Figure 3 As shown, the voltage compensation process includes the following steps: S301, retrieve the current current level value.

[0036] S302 queries the electrically erasable programmable read-only memory based on the current current level value to obtain the voltage compensation parameter table corresponding to the current current level value.

[0037] In other words, the electrically erasable programmable read-only memory maintains a table of voltage compensation parameters corresponding to each current level value. After obtaining the current current level value, the corresponding voltage compensation parameter table can be obtained based on the current current level value.

[0038] S303: Obtain the current voltage value and calculate the corresponding current voltage level value based on the current voltage value.

[0039] As an example, the voltage value can be divided into 5 different voltage levels. Specifically, when the current voltage value is equal to 1.15Un (Un is the rated voltage), the Vol_level_value is assigned the value 1; when the current voltage value is equal to 1.10Un, the Vol_level_value is assigned the value 2; when the current voltage value is equal to 1.0Un, the Vol_level_value is assigned the value 3; when the current voltage value is equal to 0.9Un, the Vol_level_value is assigned the value 4; and when the current voltage value is equal to 0.8Un, the Vol_level_value is assigned the value 5.

[0040] S304, determine whether the current voltage level value is consistent with the execution voltage level value stored in the register; if yes, proceed to step S305; if no, proceed to step S307.

[0041] S305, verify the voltage compensation parameters. If the verification is successful, return to step S301; if the verification fails, proceed to step S306.

[0042] S306, Recover the corresponding data from the electrically erasable programmable read-only memory and return to step S301.

[0043] S307: Query the voltage compensation parameter table according to the current voltage level value to obtain the current voltage compensation parameter corresponding to the current voltage level value, and correct the execution voltage compensation parameter stored in the register based on the current voltage compensation parameter corresponding to the current voltage level.

[0044] S308, update the execution voltage level value according to the current voltage level value.

[0045] It should be noted that after updating the execution voltage level value based on the current voltage level value, voltage compensation can be performed after the main program measures the current current value and obtains the corresponding current level value. Alternatively, a compensation frequency can be set for the voltage compensation program to perform voltage compensation periodically according to the compensation frequency. There is no limitation on when the voltage compensation program should be started.

[0046] In some specific embodiments, the adaptive control method further includes: querying an electrically erasable programmable read-only memory (EROM) based on the current current level value to obtain a self-heating compensation parameter table corresponding to the current current level; obtaining the current temperature value and calculating the corresponding current self-heating level value based on the current temperature value; determining whether the current self-heating level value is consistent with the execution self-heating level value stored in the register; if not, querying the self-heating compensation parameter table based on the current self-heating level value to obtain the current self-heating compensation parameter corresponding to the current self-heating level value, correcting the execution self-heating compensation parameter stored in the register based on the current self-heating compensation parameter corresponding to the current self-heating level value, and updating the execution self-heating level value based on the current self-heating level value.

[0047] As an example, such as Figure 4 As shown, the self-heating compensation process includes the following steps: S401, retrieve the current current level value.

[0048] S402: Query the electrically erasable programmable read-only memory according to the current current level value to obtain the self-heating compensation parameter table corresponding to the current current level value.

[0049] In other words, the electrically erasable programmable read-only memory maintains a table of self-heating compensation parameters corresponding to each current level value. After obtaining the current current level value, the corresponding self-heating compensation parameter table can be obtained based on the current current level value.

[0050] S403: Obtain the current temperature value and calculate the corresponding current self-heating level value based on the current temperature value.

[0051] As an example, temperature values ​​can be divided into 12 levels. Specifically, when the current temperature is -40℃, HD_level_value (self-heating level value) is assigned the value 1; when the current temperature is -30℃, HD_level_value is assigned the value 2; when the current temperature is -20℃, HD_level_value is assigned the value 3; when the current temperature is -10℃, HD_level_value is assigned the value 4; when the current temperature is -0℃, HD_level_value is assigned the value 5; when the current temperature is 10℃, HD_level_value is... 6. Assign a value to HD_level_value when the current temperature is 20℃; 7. Assign a value to HD_level_value when the current temperature is 30℃; 8. Assign a value to HD_level_value when the current temperature is 40℃; 9. Assign a value to HD_level_value when the current temperature is 50℃; 10. Assign a value to HD_level_value when the current temperature is 60℃; 11. Assign a value to HD_level_value when the current temperature is 70℃; 12.

[0052] S404, determine whether the current self-heating level value is consistent with the execution self-heating level value stored in the register; if yes, proceed to step S405; if no, proceed to step S407.

[0053] S405, Verify the self-heating compensation parameters. If the verification is successful, return to step S401; if the verification fails, proceed to step S406.

[0054] S406, Recover the corresponding data from the electrically erasable programmable read-only memory and return to step S401.

[0055] S407: Query the self-heating compensation parameter table according to the current self-heating level value to obtain the current self-heating compensation parameter corresponding to the current self-heating level value, and modify the execution self-heating compensation parameter stored in the register based on the current self-heating compensation parameter corresponding to the current self-heating level.

[0056] S308, Update the execution self-heating level value according to the current self-heating level value.

[0057] It should be noted that after updating the self-heating level value based on the current self-heating level value, self-heating compensation can be performed again after the main program measures the current current value and obtains the corresponding current level value. Alternatively, a compensation frequency can be set for the self-heating compensation program to perform self-heating compensation periodically according to the compensation frequency. There is no limitation on the timing of starting the self-heating compensation program.

[0058] In some specific embodiments, the adaptive control method further includes: acquiring the current power grid frequency and calculating the current frequency level value based on the current power grid frequency; determining whether the current frequency level value is consistent with the execution frequency level value stored in the register; if not, querying the electrically erasable programmable read-only memory based on the current frequency level value to obtain the current frequency compensation parameter corresponding to the current frequency level value, correcting the execution frequency compensation parameter stored in the register based on the current frequency compensation parameter, and updating the execution frequency compensation parameter based on the current frequency compensation parameter.

[0059] As an example, such as Figure 5 As shown, the frequency compensation process includes the following steps: S501: Obtain the current power grid frequency and calculate the current frequency level value based on the current power grid frequency.

[0060] S502, determine whether the current frequency level value is consistent with the execution frequency level value stored in the register; if yes, proceed to step S503; if no, proceed to step S505.

[0061] S503, verify the frequency compensation parameters; if the verification is successful, return to step S501; if the verification fails, proceed to step S504.

[0062] S504 recovers the corresponding data from the electrically erasable programmable read-only memory.

[0063] S505 queries the electrically erasable programmable read-only memory according to the current frequency level value to obtain the current frequency compensation parameter corresponding to the current frequency level value, and corrects the execution frequency compensation parameter stored in the register based on the current frequency compensation parameter corresponding to the current frequency level value.

[0064] S506, Update the execution frequency compensation parameters according to the current frequency compensation parameters, and return to step S501.

[0065] In some specific implementations, the adaptive control method further includes: acquiring the current harmonic components generated by the load, and performing harmonic compensation and correction based on the current harmonic components.

[0066] In other words, the adaptive control method according to the embodiments of the present invention can detect the current harmonic components generated by the load in real time, and perform compensation and correction accordingly to reduce the interference of harmonics on the power grid and prevent measurement errors caused by harmonic interference.

[0067] In summary, the adaptive control method for a wide-range energy meter according to embodiments of the present invention first obtains the current current value and calculates the corresponding current level value based on the current current value; then, it determines whether the current current level value is consistent with the execution current level value stored in the register; then, if not, it queries the electrically erasable programmable read-only memory based on the current current level value to obtain the metering parameters corresponding to the current current level value, corrects the metering parameters stored in the register based on the metering parameters corresponding to the current current level value, and updates the execution current level value based on the current current level value. Therefore, during the use of the wide-range energy meter, correcting the metering parameters based on the real-time current value can ensure the accuracy of the energy meter, improve its versatility, and thus reduce the research and development and production costs of the energy meter under complex customer requirements.
