The embodiment provides a method for checking line loss abnormality influence factors, which has the following principle: and (3) the same-period line loss electric quantity = same-period power supply quantity-same-period power selling quantity, and the line loss electric quantity is judged to be influenced by the power supply quantity and power selling quantity acquisition mode and accuracy. When the electric quantity is small, a negative value appears in the same-period line loss electric quantity, and at the moment, the reason that the same-period line loss electric quantity is the negative value needs to be checked. At present, electricity supply and sale quantity is collected by an electricity collection device and transmitted to a line loss management system, the line loss management system displays the electricity supply and sale quantity in a digital mode, but the displayed electricity supply and sale quantity is generally taken 2 or 3 bits after a decimal point, and the subsequent numerical value is discarded. Researchers find that the power supply is small, the same-phase line loss power is negative, but the same-phase line loss power is calculated in an error mode, the error has small influence on subsequent calculation, and the error can be ignored and can be taken as an allowable error. The present embodiment provides a method to quickly check whether the negative value of the power loss is the same period caused by the line loss management system accepting or rejecting the decimal of the power supply, and if so, ignore the exception.
As shown in fig. 1, the method of the present embodiment includes the following steps:
s1, acquiring digits after the electric quantity sold is a decimal;
the numerical values of the power supply quantity and the power selling quantity displayed by the line loss management system are generally taken to be 2 bits or 3 bits after a decimal point (the power supply quantity and the power selling quantity in one line loss management system have the same value taking mode), and different line loss management systems can have different value taking digits.
S2, obtaining the power supply end current transformer transformation ratio and the voltage transformer transformation ratio, and the power selling end current transformer transformation ratio and the voltage transformer transformation ratio;

S3, calculating decimal influence degree according to the acquired digit number of the decimal point of the electricity supply, the power supply end current transformer transformation ratio and the voltage transformer transformation ratio, the power sale end current transformer transformation ratio and the voltage transformer transformation ratio;
the embodiment specifically calculates the decimal fraction accepting and rejecting influence degree through the digits after the decimal fraction point of the electricity quantity sold, the maximum transformation ratio and the minimum transformation ratio of the mutual inductor so as to judge whether the synchronous line loss electricity quantity caused by decimal fraction accepting and rejecting is abnormal.
Firstly, the maximum transformation ratio and the minimum transformation ratio of a current transformer in the transformation ratios of all the current transformers at a power supply end and a power selling end are obtained. Namely, the maximum value and the minimum value of the transformation ratios of all the current transformers at the two ends of the power supply end and the power selling end are obtained.
And secondly, acquiring the maximum transformation ratio and the minimum transformation ratio of the voltage transformer in all the transformation ratios of the voltage transformers at the power supply end and the power selling end. And obtaining the maximum value and the minimum value of all the voltage transformer transformation ratios at the two ends of the power supply end and the power selling end as the current transformer transformation ratio.
And then, calculating the decimal fraction rounding influence minimum degree, wherein the decimal fraction rounding influence minimum degree = digits after the point of the power supply sale quantity is a minimum transformation ratio of the current transformer and a minimum transformation ratio of the voltage transformer.
And finally, calculating the maximum influence degree of the decimal fraction, wherein the maximum influence degree of the decimal fraction = the number of digits after the decimal point of the electricity supply sale quantity, the maximum transformation ratio of the current transformer and the maximum transformation ratio of the voltage transformer.
And after the decimal fraction rounding influence minimum degree and the decimal fraction rounding influence maximum degree are calculated, whether the decimal fraction rounding influence is the decimal fraction rounding influence or not can be judged.
It should be noted that the above process of calculating the decimal fraction influence degree does not mean the execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiment of the present application.
S4, judging whether the relation between the absolute value of the line loss electric quantity and the decimal fraction accepting and rejecting influence degree in the same period meets a preset condition or not; if so, taking the decimal of the electricity sold by the electric quantity as an influencing factor influencing the abnormality of the line loss electricity in the same period;
the specific steps of judging whether the preset conditions are met are as follows: and judging whether the absolute value of the line loss electric quantity in the same period is between the minimum degree of decimal fraction selection and the maximum degree of decimal fraction selection and division influence.
That is, if the absolute value of the power loss in the same period is between the minimum degree of the power loss in the decimal place and the maximum degree of the power loss in the decimal place, it indicates that the power loss in the same period is abnormal due to the decimal place for selling power, and the influence can be ignored. If the absolute value of the line loss electric quantity in the same period is not between the decimal place influence minimum degree and the decimal place influence maximum degree, the fact that the factor causing the abnormal line loss electric quantity in the same period is not the decimal place for selling the electric quantity but other reasons is shown, and other reasons are checked at the moment.
