The Correction Technology of Abnormal Power Based on Arbitrary Division of Power Grid

According to the current situation of failure of data collection and abnormal data collection in the same period line loss calculation and access data of power grid, the abnormal data of various data integrated in the same period system is relatively high, and the abnormal information screening, management and verification of data are lacking. In this paper, based on the topology recursion of transmission network, the function of correcting abnormal data in any divided area is presented. The calculation relation among the unbalance rate of bus bar, main transformer power loss and transmission line power loss is generated through transmission network topology recursion technology, and the substation. Through the transmission network topology recursion technology and the principle of node power balance, the abnormal substation is checked and repaired by itself in the station, and according to whether it can be checked and repaired by itself, it is determined whether to expand the power grid division area and the scope of check calculation. As much as possible, the normal data of other areas are used to check and correct the abnormal data of the suspected substation, which can quickly and effectively lock and correct the abnormal data, thus improving the availability rate and calculation quality of the theoretical calculation data of line loss.
