Embodiment Construction
[0070] The technical scheme of the present invention is described in detail below in conjunction with accompanying drawing:
[0071] Such as figure 1 , through the accumulation of electrical quantity data of each node on the station area side and the analysis of the station area structure, it can be concluded that each branch outgoing line on the distribution side of the station area corresponds to the incoming line of the lower branch box, and each outgoing line of the branch box corresponds to one or more lower end In theory, the outgoing power of the upper node is equal to the incoming power of the lower nodes in the same time period. This method utilizes this power conservation relationship and combines the incremental relationship that the line loss at the lower end of the station area is greater than the line loss at the upper end to realize the topology identification of the station area with constrained multi-objective optimization.
