摘　　要：针对电网工程构件的GIM模型无法包含造价分析所需要的所有信息,导致造价分析精度及效率较低的问题,提出了一种基于多源异构数据融合的造价数据与GIM模型的挂接方法。该方法建立了电网工程GIM构件属性集和造价数据库,并从中提取出构件本体来实现GIM构件到本体间的映射以及造价数据到本体间的映射关系,进而完成多源异构的造价数据与GIM模型间的挂接。仿真实验及分析结果表明,所提方法能够大幅节省造价分析人员的查询和计算时间,从而提高电网工程造价分析与管理的效率。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.
