[0027] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present invention. However, it should be clear to those skilled in the art that the present invention may be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present invention.

"And / or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships.

The words "first", "second", etc. do not limit the quantity and execution order, and the words "first", "second", etc. do not limit them to be different.

[0029] In the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a concrete way for easy understanding.

[0030] In addition, the terms "including" and "having" and any variations thereof mentioned in the description of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or modules is not limited to the listed steps or modules, but may optionally include other steps or modules that are not listed, or may optionally include other steps or modules that are inherent to these processes, methods, products or devices.

[0031] In order to make the purpose, technical solutions and advantages of the present invention more clear, the following will be described through specific embodiments in conjunction with the accompanying drawings of the present invention.

[0032] Smart meters are one of the basic devices used for smart grid data collection. They undertake tasks including raw power data collection, measurement and transmission. They are also the basis for information integration, information analysis optimization and presentation. The measurement error of the power meter is directly related to the economic benefits of both the power supplier and the user. Therefore, both parties have put forward high requirements for the accuracy of power metering. The measurement accuracy of smart power meters is of great significance.

[0033] When producing electric energy meters, the electric energy measurement accuracy of the electric energy meters is calibrated and tested in a normal temperature working environment with a reference temperature of 20°C when the electric energy meters leave the factory, and the electric energy measurement accuracy of the electric energy meters is related to the ambient temperature. Due to the influence of the actual ambient temperature change, the electric energy measurement accuracy of the electric energy meters will have a relatively large deviation, so that the electric energy meters cannot accurately and fairly measure.

[0034] Due to the influence of environment, weather, day and night, such as the influence of the northern and southern hemispheres, sunny and cloudy days, etc., the electric energy meter will have different degrees of heating. Once the temperature of the electric energy meter changes, the measurement of electricity will be wrong over a long period of time. At present, there are many schemes for temperature compensation of electric energy meters, but none of them verifies the temperature compensation data after temperature compensation of electric energy meters, resulting in inaccurate measurement data after temperature compensation of electric energy meters.

[0035] To solve the above technical problems, Figure 1 As shown, an embodiment of the present invention provides a method for verifying temperature compensation data of an electric energy meter. The verification method is executed by a verification device for temperature compensation data of an electric energy meter. The verification method includes steps S101-S103.

[0036] S101. A verification device determines the temperature compensation coefficient of the electric energy meter to be tested, the actual metering data of the electric energy meter to be tested, and the standard metering data of the standard electric energy meter at the current temperature.

[0037] The temperature compensation coefficient is used to compensate the metering data of the electric energy meter at a specific temperature, so that the compensated data reduces the influence of temperature on the metering of the electric energy meter.

[0038] As a possible implementation manner, the verification device may determine the temperature compensation coefficient of the electric energy meter to be tested at the current temperature based on the current temperature and a mapping relationship between the temperature and the temperature compensation coefficient.

[0039] As a possible implementation, the embodiment of the present invention can use the electric energy meter to be tested and the standard electric energy meter to test the same point to be tested, so as to verify that the device detects actual metering data of the electric energy meter to be tested and standard metering data of the standard electric energy meter.

[0040] S102. The verification device performs temperature compensation on the actual measurement data based on the temperature compensation coefficient to obtain temperature compensated data.

[0041] As a possible implementation manner, the verification device may use the product of the actual measurement data and the temperature compensation coefficient as the temperature compensation data.

[0042] S103. Obtain a relative error based on the temperature compensation data and the standard measurement data.

[0043] In some embodiments, the relative error is used to characterize the difference between the metering data of the electric energy meter under test after temperature compensation and the standard metering data of the standard electric energy meter, that is, the difference between the temperature compensated data and the standard metering data.

[0044] As a possible implementation manner, the verification device may use the difference between the temperature compensation data and the standard measurement data as a relative error.

[0045] As another possible implementation, the verification device may determine the relative error according to the following formula:

[0046]

[0047] Among them, ε is the relative error, ε y is the intermediate loss coefficient, y(i) is the standard measurement data; ε0 is the fixed loss coefficient; To compensate the data.

[0048] S104: If the relative error is less than a preset threshold, the verification device determines that the temperature compensation data of the electric energy meter to be tested is qualified.

[0049] The method for verifying the temperature compensation data of an electric energy meter provided by the present invention can verify the metering data after the electric energy meter is temperature compensated, and when the relative error is less than a preset threshold, it is determined that the temperature compensation data of the electric energy meter to be tested is verified to be qualified, thereby improving the accuracy of the metering data after the electric energy meter is temperature compensated.

[0050] Optional, such as Figure 2 As shown, before step S101, the verification method further includes steps S201-S203.

[0051] S201. At a preset temperature, a verification device obtains first metering data of an electric energy meter to be tested and second metering data of a standard electric energy meter.

[0052] The preset temperature may be any temperature that may occur during the operation of the electric energy meter. For example, the preset temperature may be any temperature between 0° and 60°, such as 25°, 30°, etc.

[0053] As a possible implementation method, at a preset temperature, an embodiment of the present invention can use the electric energy meter to be tested and the standard electric energy meter to detect the same point to be tested, so that the verification device obtains the first metering data of the electric energy meter to be tested and the second metering data of the standard electric energy meter.

[0054] S202: The verification device determines a temperature compensation coefficient based on the first measurement data and the second measurement data.

[0055] It is understandable that, due to the influence of temperature, there is a difference between the first metering data detected by the electric energy meter to be tested and the second metering data detected by the standard electric energy meter, and the verification device can determine the temperature compensation coefficient based on the difference.

[0056] As a possible implementation manner, the verification device may determine the ratio of the first measurement data to the second measurement data as the temperature compensation coefficient.

[0057] S203: The verification device establishes a mapping relationship between a preset temperature and a temperature compensation coefficient.

[0058] based on Figure 2 In the illustrated embodiment, the verification method provided by the present invention can detect and determine the temperature compensation coefficient based on different temperatures, thereby establishing a mapping relationship between temperature and temperature compensation coefficient, which is convenient for verifying the temperature compensation data.

[0059] Optional, such as Figure 2 As shown, before step S101, the verification method further includes steps S301-S304.

[0060] S301. At a reference temperature, a verification device obtains a first equivalent impedance of an electric energy meter.

[0061] S302: Under a preset temperature, the verification device obtains a second equivalent impedance of the electric energy meter.

[0062] S303: The verification device determines a temperature compensation coefficient based on the first equivalent impedance and the second equivalent impedance.

[0063] It is understandable that the equivalent impedance of the energy meter is different at different temperatures, which results in different measurement of electric energy, leading to measurement errors in the energy meter and inaccurate measurement data. Therefore, the verification device can determine the temperature compensation coefficient of the energy meter based on the equivalent impedance of the energy meter at different temperatures.

[0064] As a possible implementation manner, the verification device may determine the ratio of the second equivalent impedance to the first equivalent impedance as the temperature compensation coefficient.

[0065] As another possible implementation method, the verification device can detect the equivalent impedance of the electric energy meter at multiple temperatures, and then determine the fitting function of the equivalent impedance of the electric energy meter and temperature based on the equivalent impedance of the electric energy meter at multiple temperatures to establish a mapping relationship between the equivalent impedance of the electric energy meter and temperature.

[0066] S304: The verification device establishes a mapping relationship between a preset temperature and a temperature compensation coefficient.

[0067] based on Figure 3 In the illustrated embodiment, the verification method provided by the present invention can detect and determine the equivalent impedance of the electric energy meter based on different temperatures, thereby establishing a mapping relationship between temperature and temperature compensation coefficient, which is convenient for verifying the temperature compensation data.

[0068] It should be understood that the order of execution of the steps in the above embodiment does not necessarily mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiment of the present invention.

[0073] In a possible implementation, the processing module 402 is specifically configured to determine the relative error according to the following formula:

[0074]

[0075] Among them, ε is the relative error, ε y is the intermediate loss coefficient, y(i) is the standard measurement data; ε0 is the fixed loss coefficient; To compensate the data.
