摘要
The rapid change and uncertainty of power grid operation state put forward higher requirements for the basic data of online calculation. A fast estimation method of grid operation state based on multi-source data is proposed. Based on the different characteristics of multi-source heterogeneous data, a unified data storage method is established to realize efficient storage and access of different data sources. A selfcheck and correction method of PMU and RTU based on historical measurement error is proposed to reduce the influence of abnormal data on data integration accuracy. A multi-source data fusion method is utilized to realize the rapid generation of sectional power flow and topological information at the current moment. The correctness and feasibility of the proposed method are verified based on the actual power grid.
