It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.

Example one
Fig. 1 is a flowchart of a power consumption statistical method according to an embodiment of the present invention, where the present embodiment is applicable to a situation where a power consumption is counted and a measured power is calibrated in a substation, the method may be executed by a power consumption statistical apparatus, the power consumption statistical apparatus may be implemented by software and/or hardware, and may be configured in a computer device, such as a server, a workstation, a personal computer, and the like, and the method specifically includes the following steps:
and S110, acquiring original electric energy data for metering the electric consumption of the electric consumer.
In this embodiment, the electric energy data that the metering device meters the electricity consumption of the electricity consumer may be directly counted as the original electric energy data, and since the metering device may be generally controlled and managed by a metering automation system in the substation, most of the electric energy data measured by the metering device may be summarized to the metering automation system, the original electric energy data that the electricity consumption of the electricity consumer is metered may also be obtained from the metering automation system of the substation by using a crawler technology. The frequency of acquiring the raw power data may be preset, and generally, the frequency of acquiring the raw power data for measuring the power consumption of the power consumer from the substation is once a day, which is not limited in this embodiment.
And S120, determining electric energy data with abnormal numerical fluctuation in the original electric energy data compared with preset reference electric energy data as abnormal electric energy data.
Because partial electric energy data possibly exists in the original electric energy data acquired by the embodiment and is acquired by metering under the conditions of faults, wrong wiring and the like of the electric energy metering device, the partial electric energy data has abnormal values and needs to be screened from the original electric energy data for independent correction.
Preferably, in the embodiment, the original electric energy data is compared with the preset reference electric energy data, and it may be determined that electric energy data with abnormal numerical fluctuation exists in the original electric energy data compared with the preset reference electric energy data as abnormal electric energy data.
In a specific implementation manner, electric energy data distributed to power consumers can be acquired from an electric power dispatching system of a transformer substation as preset reference electric energy data; determining reference electric energy data with the same acquisition period as the original electric energy data as target reference electric energy data; fitting the target reference electric energy data to obtain a first electric energy curve; fitting the original electric energy data to obtain a second electric energy curve; and comparing the first electric energy curve with the second electric energy curve, and determining that the electric energy data with abnormal numerical fluctuation exists in the second electric energy curve as abnormal electric energy data.
In another specific implementation manner, the acquisition cycle of the original electric energy data may be determined as the tth cycle, that is, the electric energy data in which the transformer substation measures the power consumption of the power consumer in the tth cycle; and taking the electricity consumption statistical data in the T-1 th period, the T-2 nd period and the T-3 rd period obtained from the transformer substation as a plurality of reference electric energy data, wherein the electricity consumption statistical data in the T-1 th period, the electricity consumption statistical data in the T-2 nd period and the electricity consumption statistical data in the T-3 rd period are corrected metering electric quantity data, and performing numerical comparison on the original electric energy data and each reference electric energy data respectively to determine abnormal electric energy data in the original electric energy data.
And S130, inquiring the number of the power consumers using the same metering equipment to represent the types of the power consumers.
In this embodiment, the number of the power consumers using the same metering device may be queried, if the number is greater than a preset threshold, the type of the power consumer may be determined to be a multi-user type, and if the number is less than or equal to the preset threshold, the type of the power consumer may be determined to be a single-user type, and the number of the power consumers connected to the metering device may also be determined based on a circuit connection manner of the metering device, for example, the type of the power consumer connected to the metering device using a high-supply high-count three-phase wire connection method is a single-user type.
And S140, calculating the electric quantity difference between the abnormal electric energy data and the reference electric energy data based on the type.

In one example, when the type is a single-user type, the cell power difference may be calculated based on a power comparison between the abnormal power data and the reference power data. Specifically, the power of the abnormal electrical energy data may be determined as the abnormal wiring power, for example, the voltage, the current and the phase angle may be read from the abnormal electrical energy data, and the product of the voltage, the current and the phase angle may be calculated to obtain the abnormal wiring power; determining the power of the reference electric energy data as correct wiring power; calculating the ratio of the correct wiring power to the abnormal wiring power; calculating the difference between the ratio and 1; determining actual consumed electric quantity corresponding to correct wiring power; and taking the product of the difference value and the actual consumed electric quantity as the monomer electric quantity difference.
In another example, when the type is a multi-user type, the accumulated power difference may be calculated based on a fitting function of positive and negative powers in the reference power data and a time period determined by the abnormal power data. Specifically, determining the time period of abnormal electric energy data; extracting a plurality of discrete values representing power from the reference power data according to a time period, the power including negative power and positive power; fitting the discrete values according to positive power and negative power respectively to obtain a target fitting function; and integrating the target fitting function in a time period to obtain an accumulated electric quantity difference.
Wherein, fitting the discrete values according to the positive power and the negative power respectively to obtain a target fitting function, which specifically includes: respectively fitting the discrete numerical values representing the positive power and the discrete numerical values representing the negative power, and determining a fitting curve formed by the discrete numerical values; determining a ring ratio fitting curve and a homonymy fitting curve matched with the fitting curve, wherein the homonymy fitting curve is the fitting curve obtained by the homonymy electric energy data of the abnormal electric energy data in a discrete fitting mode, and the ring ratio fitting curve is the fitting curve obtained by the homonymy electric energy data of the abnormal electric energy data in the discrete fitting mode; and performing numerical correction on the fitting curve by using the ring ratio fitting curve and the homonymous fitting curve to obtain a target fitting function.
And S150, performing exception processing on the electricity consumption of the electricity consumer according to the electricity consumption difference.

In an example, the calculated electricity quantity difference may be numerically determined, when the electricity quantity difference is a negative value, it indicates that the correct wiring power is less than the abnormal wiring power, and indicates that the data obtained by metering the electricity consumption of the electricity consumer by the metering device is greater than the actual electricity consumption of the electricity consumer, and the electricity charge corresponding to the electricity quantity difference needs to be returned to the electricity consumer, for example, the electricity charge corresponding to the electricity quantity difference may be returned to the electricity consumer according to a rule of step charging; when the electricity quantity difference is a positive value, it indicates that the correct wiring power is greater than the abnormal wiring power, and the data indicating that the metering equipment meters the electricity consumption of the electricity consumer is less than the actual electricity consumption of the electricity consumer, the electricity consumer is notified to make up the electricity charge corresponding to the electricity quantity difference, for example, the electricity charge which the electricity consumer should make up can be calculated according to the step charging rule.
The method comprises the steps of acquiring original electric energy data for metering the electricity consumption of an electricity consumer; determining electric energy data with abnormal numerical value fluctuation in comparison with preset reference electric energy data in the original electric energy data as abnormal electric energy data; inquiring the number of power consumers using the same metering equipment to represent the types of the power consumers; calculating a power difference between the abnormal power data and the reference power data based on the type; and carrying out exception processing on the electricity consumption of the electricity consumer according to the electricity quantity difference. According to the scheme, the data of the electric quantity metering is checked aiming at different electric quantity types, the data disorder in the electric quantity counting process can be avoided, the electric quantity difference corresponding to different electric quantity types is calculated, the electric quantity difference is used for automatically correcting the electric quantity data of the electric quantity users, the metering fault can be timely recovered, and the manpower and material resource costs in the electric quantity data counting process are saved.
