Description

Technical Field

[0001] The present invention relates to the field of electric power technology, and in particular to a method, device, equipment and storage medium for calculating the amount of electricity compensated for wiring errors in three-phase load imbalance measurement. Background Art

[0002] In the current electricity metering system, ordinary electricity users usually only install billing electricity metering devices, but lack assessment or reference electricity metering devices. This situation leads to a lack of reference records to accurately calculate the amount of electricity to be compensated when the billing electricity metering device has a wiring error. Accurately calculating the amount of electricity to be compensated when the wiring is incorrect according to the difference rate between correct wiring and incorrect wiring is the basis for maintaining the interests of power companies and electricity users.

[0003] At present, when calculating the amount of electricity to be compensated in the case of wiring errors in the billing electric energy metering device, the staff usually uses theoretical formulas or the form of synchronous electricity to calculate the amount of electricity to be compensated according to the on-site situation. On the one hand, the theoretical formula calculation method is based on the assumption that the three-phase symmetry is carried out, that is, it is assumed that the three-phase voltage is the same. , the three-phase current is the same , the three-phase power factor is the same In actual work, the three phases of voltage, current and power are not exactly the same. If the assumption is not established and the calculation basis is insufficient, it is easy to bring negative impacts such as public opinion risk, corruption risk, and complaints from power users to power companies. On the other hand, one of the key factors in the correction coefficient is the power factor angle. In actual work, the value of the power factor angle directly determines the amount of make-up electricity. However, there is currently no method to accurately determine the power factor angle, and thus the make-up electricity cannot be accurately determined. At the same time, when there are individual incorrect wiring methods, the correction coefficient cannot be calculated, and the amount of electricity to be made up can only be calculated in the form of the same period electricity. The deviation of the make-up electricity value is large. When the calculation of the make-up electricity is wrong, it will cause economic losses to the power company or power users. Summary of the invention

[0027] It should be noted that the electric energy metering device is a device for measuring and recording electric energy, such as an electric energy meter, which can measure the total amount of electric energy passing through the circuit within a period of time; the first calculation element and the second calculation element are arranged in the electric energy metering device, and are components for calculating electric energy according to voltage, current and power factor angle; the wrong wiring method refers to a wiring method that does not conform to the standard wiring method of the electric energy metering device, which can lead to inaccurate electric energy measurement. In this embodiment, preferably, it includes the wiring method of the first calculation element and the wiring method of the second calculation element; the meter-metered electric quantity is the electric quantity recorded by the electric energy metering device under the wrong wiring method. Due to the wiring error, this part of the electric quantity is not accurate. Therefore, detailed calculation steps from obtaining parameters to determining the amount of electric quantity to be compensated are provided, with clear steps and strict logic, which is convenient for programming to realize automatic calculation, reduces manual intervention, improves work efficiency, and realizes standardization of actual operation and calculation process.

Thus, a more accurate and sufficient basis is provided for the calculation of the make-up electricity, and the negative impact on the enterprise caused by insufficient calculation basis is avoided.

[0030] In one embodiment, the obtaining of the power factor angle of the first calculation element when the wiring is incorrect and the power factor angle of the second calculation element when the wiring is incorrect specifically includes: Acquire a power factor curve of the first calculation element when the wiring is incorrect and a power factor curve of the second calculation element when the wiring is incorrect; Determining a power factor angle curve of the first calculation element when the wiring is incorrect according to the power factor curve of the first calculation element when the wiring is incorrect and the arc cosine function; The power factor angle curve of the second calculation element in the case of a faulty wiring is determined based on the power factor curve of the second calculation element in the case of a faulty wiring and the arccosine function.

It should be noted that the power factor angle curve of the first calculation element and the power factor angle curve of the second calculation element at the time of wrong wiring can be obtained by collecting the power factor of the first calculation element and the power factor angle curve of the second calculation element at each time node. In this embodiment, preferably, the data acquisition module is an electricity information acquisition system. The power factor curve of the first calculation element and the power factor curve of the second calculation element corresponding to the time node (a total of 96 per day, including 0:00, 0:15, 0:30...23:45) during the wrong wiring period are obtained by using the electricity information acquisition system.
