Embodiment Construction

[0033] The embodiments of the present invention are described in further detail below in conjunction with the accompanying drawings, but the present embodiments are not intended to limit the present invention. All similar structures and similar changes of the present invention should be included in the scope of protection of the present invention. The commas in all indicate the relationship between and.

[0034] Such as figure 1 As shown, a method for processing abnormal active energy provided by the embodiment of the present invention is characterized in that the specific steps are as follows:

[0035] 1) Divide each day into Y time points by setting a time point every x minutes;

[0036] Among them, the value of x is usually 5 minutes, and the value of Y is usually 288;

[0037] 2) Obtain the active energy W(t) and active power P(t) at the tth time point of the current day, and the active energy W(t-1) and active power P at the t-1th time point of the current day (t-1); ...

Abstract

The invention relates to an abnormal active power electric quantity processing method and belongs to the power system technical field. With the method adopted, the accuracy of the power consumption calculation of equipment can be increased. The method includes the following steps that: active power electric quantity and active power a t-th time point and a (t-1)-th time point of a current date and the active power electric quantity and active power historical data of a date before the current date are obtained; and the active power electric quantity increment average value and active power increment average value of the date before the current date are calculated, abnormal time points of the date before the current date are eliminated, the active power electric quantity increment corrected average value and active power increment corrected average value of the date before the current date are calculated, anomaly discrimination is performed on the active power electric quantity and active power at the t time point, and abnormal data of the time point are corrected. The method provided by the invention has the advantages of simplicity in realization and high correction precision.

Description

technical field [0001] The invention relates to power system technology, in particular to the technology of a method for processing abnormal active energy. Background technique [0002] All smart meters adopt the method of sending the frozen electricity to the data center, so there is no problem of data mutation. However, in the low-voltage monitoring system, it is often necessary to calculate the power consumption of the equipment in real time to find out abnormal equipment. Due to the quality of the communication channel, the real-time power measurement in the monitoring system often has sudden changes and missing situations. [0003] Abnormal active energy measurement includes active energy measurement value error, sudden change, missing, etc. Errors and sudden changes in active energy measurement will affect the accuracy of equipment power consumption calculations. The absence of energy measurements will also cause errors in equipment utilization. There is currently no...
