Linking method based on fusion of multi-source heterogeneous data for cost data and GIM model
Aiming at the problem that the GIM model constructed by the power grid project cannot contain all the information needed for cost analysis,resulting in low cost analysis accuracy and efficiency,a method based on the fusion of multi-source heterogeneous data for linking cost data and GIM model was proposed.Through the establishment of attribute set for GIM components of power grid engineering,the cost database and the extraction of component ontology,the mapping between GIM components and the ontology and the mapping relationship between cost data and ontology were realized,and then the linking between the multi-source heterogeneous cost data and the GIM model was achieved.Simulation analysis and experimental results show that the as-proposed method can significantly save the query and calculation time of cost analysis,and improve the efficiency of cost analysis and management for power grid engineering.
