4. The intelligent monitoring terminal for power distribution according to claim 1, characterized in that: The total power consumption before the C1 cycle node is calculated as follows: P 后 =P1+P2+…+P a+1 ; P 后 is the total power consumption at the corresponding cycle node after the split point, P a+1 It is the power consumption value corresponding to the adjacent period node (a+1) on the over-standard curve after the split point; The calculation formula for the numerical deviation in C2 is: S=(Q1+Q2+…+Q a+1 )-P 后 ; S is the numerical deviation, and (Q1+Q2+…+Q a+1 ) is the total power distribution corresponding to the period node (a+1); And the numerical deviation S is related to the power consumption value Q at the subsequent cycle node (a+2) a+2 The comparison produces the following results: Result 1: S<Q a+2 , then the period node at (a+1) is the abnormal prediction point; Result 2: S ≥ Q a+2 , then the period node at (a+1) is not an abnormal prediction point.
5. The intelligent monitoring terminal for power distribution in a power grid according to claim 1, characterized in that: The operation of the data analysis unit combining the real-time data set data with the intelligent monitoring model to predict the subsequent power consumption of the power consumption area is: D1. The real-time data set data is introduced into the optimized intelligent monitoring model, and a curve is formed synchronously for segmentation operation. The data before segmentation does not need to be analyzed, and the periodic nodes after segmentation implement analysis operations in sequence; D2. And find out the real-time abnormal prediction point accordingly, and when the abnormal prediction point occurs, it is necessary to generate a distribution dispatch instruction.
6. The intelligent monitoring terminal for power distribution in a power grid according to claim 5, characterized in that: The setting operation of the power distribution dispatching instruction in D2 is: E1. Take the area where the abnormal prediction point currently exists as the center point, extract the distances between other distribution areas and the center point, and sort them in order from near to far; E2, and determine whether there are abnormal prediction points in other distribution areas based on the results of the analysis, and extract areas without abnormal prediction points based on the E1 operation; E3. Based on the E2 operation, determine whether the numerical deviation of the corresponding cycle node in other areas is greater than the sum of the power consumption value at the subsequent cycle node and the power consumption value at the subsequent cycle node of the area where the abnormal prediction point currently exists. If so, the area that is ranked first among the areas that simultaneously meet the E1 to E3 operations will perform a distribution transfer operation to the current abnormal area.
