Abstract:At present, the electric information acquisition system has basically realized full coverage, which provides data support for a variety of services. Due to the failure of the acquisition equipment, the unstable communication channel and the external interference, the abnormal electric energy data will be collected by the electric information acquisition system. It is necessary to identify and repair the abnormal electric energy data. This article proposed a method of identifying and repairing abnormal data in acquisition system based on the physical laws of load data and electric energy data and corresponding mathematical algorithm. According to the load data, the power consumers are divided into three types, such as full load data, incomplete load data and no load data. And the mathematical models of abnormal electric energy repair corresponding to each type are established respectively. The validity of the proposed method was demonstrated by calculation examples.
