Embodiment Construction
[0102] Such as figure 1 As shown, the steps of the error detection method of the electric energy metering device based on big data deduction in this embodiment include:
[0103] 1) Obtain multiple sets of electric energy data of each line in the designated voltage area of the substation to be evaluated;
[0104] 2) Calculate the corresponding bus power imbalance rate according to each set of electric energy data, and establish a mapping model between electric energy and bus power imbalance rate according to multiple sets of electric energy data and the corresponding bus power imbalance rate;
[0105] 3) Create N virtual lines, N is the number of lines in the specified voltage area of the substation to be evaluated, take any two virtual lines to form a line pair, set one of the line pairs as the current line pair, and set the metered power of one of the virtual lines The value is the measurement benchmark, and the other virtual line is the comparison object; set the power ...
