By adopting the embodiment of the invention, only the collected abnormal electricity utilization data is utilized, and the calculation formula in the technical scheme can accurately calculate the small electricity consumption amount of abnormal current climbing so as to supplement the small electricity consumption amount of abnormal users and reduce the workload of collecting normal electricity utilization data.
On the basis of the above-described embodiment, various modified embodiments are further proposed, and it is to be noted herein that, in order to make the description brief, only the differences from the above-described embodiment are described in the various modified embodiments.
According to some embodiments of the invention, the manner of collection includes, but is not limited to, data collection by an electrical data collection tool. The collected data includes, but is not limited to, current values of each phase, voltage values of each phase, total electric energy indicating value of active power, total electric energy indicating value of reactive power, and comprehensive multiplying power of transformer area.
According to some embodiments of the invention, the acquiring abnormal electricity utilization data of the three-phase three-wire user with the abnormal current climbing comprises:
and in a preset time period, acquiring abnormal electricity utilization data of the three-phase three-wire user with abnormal current climbing according to a preset period so as to calculate the average small electricity consumption of the abnormal current climbing in the preset time period.
For example, electricity consumption data of a three-phase three-wire user with a climbing abnormality in 24 hours is collected, and data collection is performed at a frequency of once every 15 minutes, that is, T =24h and I = 96.
The period and the time length of data acquisition can be adjusted according to actual conditions.
According to some embodiments of the invention, the preset time period is the day when the three-phase three-wire user with the current climbing abnormality is the earliest to have the abnormality.
The value interval of the preset period is [5min, 30min ]. For example, the data acquisition period is set to 15min, so that 96 groups of power utilization data with abnormal current climbing are obtained.
According to some embodiments of the invention, the abnormal electricity data includes a phase electricity data and a phase C electricity data.
The screening of the power consumption data of the normal phase and the power consumption data of the abnormal phase from the abnormal power consumption data comprises the following steps:
and observing the curve trend of the current in the A-phase electricity utilization data and the curve trend of the current in the C-phase electricity utilization data to identify which item of the A-phase electricity utilization data and the C-phase electricity utilization data is electricity utilization data of a normal phase, and the other item of the A-phase electricity utilization data and the C-phase electricity utilization data is electricity utilization data of an abnormal phase.
According to some embodiments of the invention, the power factor data may be acquired directly.
According to some embodiments of the invention, the power factor data may be acquired indirectly. For example, the active power P of abnormal electricity utilization can be acquired through collectionActive powerAnd reactive power QReactive powerThen, the power factor f is calculated according to the following formula:
Figure DEST_PATH_IMAGE018AAA
。
in another example, the active power P of one phase of abnormal electricity utilization is acquired through collectionActive powerCurrent I, voltage U, then calculating the power factor f according to the following formula:
Figure DEST_PATH_IMAGE020AAA
。
according to some embodiments of the invention, the electricity utilization data of 24 hours on the day of the current climbing abnormality of the three-phase three-wire user is collected, wherein the abnormality occurs at the earliest time, and the collection period is 15 minutes, so that 96 groups of abnormal electricity utilization data are obtained. For a three-phase three-wire user, the data of the phase B is 0, only the phase A and the phase C have values, and the method is obtained according to the law of energy conservation:
Figure 29238DEST_PATH_IMAGE021
in the formula 3, the first and second phases,
wherein the content of the first and second substances,
Figure 559576DEST_PATH_IMAGE022
as a result of the total active power,
Figure 578348DEST_PATH_IMAGE023
is the active power of the phase A,
Figure 662978DEST_PATH_IMAGE024
and is C-phase active power.
For a three-phase three-wire user, under the condition of current climbing abnormity, the method comprises the following steps of:
Figure 159819DEST_PATH_IMAGE025
in the case of the formula 4,
wherein the content of the first and second substances,
Figure 75822DEST_PATH_IMAGE022
as a result of the total active power,
Figure 436134DEST_PATH_IMAGE026
the active power corresponding to the normal phase when the user has abnormal current climbing,
Figure 804799DEST_PATH_IMAGE027
the active power corresponding to the abnormal phase when the user has abnormal current climbing.
Due to the existence of an equation
Figure 105330DEST_PATH_IMAGE028
Wherein, P is the active power of a certain phase, I is the current of the corresponding phase, U is the voltage of the corresponding phase, and f is the power factor of the corresponding phase.
Thus, equation 4 can be approximated by equation 5 as follows:
Figure 79102DEST_PATH_IMAGE029
in the case of the formula 5,
wherein the content of the first and second substances,
Figure 908518DEST_PATH_IMAGE030

Figure 570498DEST_PATH_IMAGE032
the power factor of the ith acquisition moment on the day of normal phase anomaly;
Figure 195515DEST_PATH_IMAGE033
the current of the abnormal phase at the ith acquisition moment on the day of abnormality;
Figure 461411DEST_PATH_IMAGE034
is abnormal phase atVoltage at the ith acquisition moment on the abnormal day;
Figure 742351DEST_PATH_IMAGE035
is the power factor of the anomalous phase at the ith acquisition time on the day of the anomaly.
Substituting equation 2 into equation 5, and since
Figure 650264DEST_PATH_IMAGE036
Then, obtaining:
Figure 97163DEST_PATH_IMAGE037
in the case of the formula 6,
when the user is normal, that is, when there is no abnormality in the current climbing, the normal phase is still recorded as the normal phase so as to be coincident with the mark in the abnormal state
Figure 2802DEST_PATH_IMAGE038
And the abnormal phase is recorded as
Figure 914913DEST_PATH_IMAGE039
At this time exist
Figure 564201DEST_PATH_IMAGE036
And
Figure 367072DEST_PATH_IMAGE040
and the power factor of each phase under normal and abnormal conditions is unchanged, so the calculation formula of the total active power under normal conditions is as follows:
Figure 224038DEST_PATH_IMAGE041
in the formula 7, the first and second groups,
therefore, the difference between the total active power in the normal case and the abnormal case is as follows:
Figure 441087DEST_PATH_IMAGE042
in the case of the formula 8,
since the interval between every two time points is 15 minutes, namely 1/4 hours, the difference between the normal power consumption and the abnormal power consumption is as follows without considering the comprehensive multiplying power:
Figure 97328DEST_PATH_IMAGE043
in the formula 9, the first and second groups,
because the electric energy number of the special transformer user is obtained after dividing by the comprehensive multiplying power, the daily-average power-less formula for the abnormal and accurate three-phase three-wire current climbing is as follows:
Figure 285864DEST_PATH_IMAGE044
