摘　　要：随着电力系统的快速发展,其规模和复杂度正在急剧增加。电力系统需要更加高效的数据管理和更快的分析计算工具。这些挑战可以通过图数据模型和图计算技术得到很好的解决。图数据模型可以为电力系统提供高效的数据管理手段,同时图计算可以通过并行计算提高分析计算速度。文章提出了一种基于图数据模型的配电网建模方法,并在此基础上开发了基于图计算的并行潮流算法和基于图数据库的配电网分析软件。所提出的并行潮流算法可以有效地提高计算效率,减少潮流计算时间。同时,开发的配电网分析软件可以提供灵活的可视化功能和强大的数据分析及管理功能。With the emergence of the graph database and the graph computing technologies,the power system is facing a new era of technology development. Meanwhile,the fast-growing power distribution systems with increased scale and complexity require more efficient data management and faster power flow solving algorithm. These challenges could be well solved by applying the graph data model(GDM) and graph computing technologies as the GDM provides more efficient data management methods and the graph computing is suitable for the node to improve the speed of analysis and calculation based parallel computing. This paper proposes a GDM based power distribution network modeling approach. Based on this,a parallel power flow algorithm based on graph computing and distribution system analysis software based on graph database are developed. The proposed parallel power flow algorithm is implemented on a graph database platform and the simulation results show that it is able to effectively reduce the computing time of the power flow with large test systems. Moreover,the power flow software is able to provide vivid data visualization and perform flexible data analysis and data management functions.
