The invention discloses a method for filling missing data in the power grid. The monitoring and collection of various data in the power system is the basis for the power system scheduling operation, safety and stability analysis, equipment status and risk assessment. However, in the actual operation of the power system, due to the wrong data acquisition channel and the failure of the remote terminal unit, the observed data will appear abnormal, which is inconsistent with most of the observed values. It may cause the observation data to violate the routine and make the analysis of the power system data difficult for the smart grid system. Therefore, a data supplement method should be used to supplement the missing data before data analysis, so as to improve the accuracy and efficiency of power system data analysis. Availability of curve data to support subsequent analysis. |
