摘　　要：厂站节点和网络拓扑的自动布局是实现机电-电磁暂态仿真模型自动转化的重要环节,对提高大规模电力系统的建模效率和准确性具有重要意义。现有布局方法多局限于交叉点数和布局均匀性等方面的研究,未考虑厂站节点间的实际相对位置,导致每次布局结果极不稳定。提出一种基于弹簧电子力模型用于大规模机电-电磁暂态仿真模型自动转化的分层布局方法。该方法充分考虑节点间的实际相对位置,对不同电压等级的厂站节点逐层布局,解决了传统方法每次布局结果差异较大的问题,不仅可以用于绘制机电暂态地理接线图,还可以提供电磁暂态仿真模型的节点坐标信息。对美国西部电网3机9节点、新英格兰10机39节点,以及某地区输电网络系统进行算例测试与分析,验证了所提方法的有效性。The automatic layout of station nodes and network topology is a vitally important link to realize the automatic transformation of electromechanical-electromagnetic transient simulation model, which is of great significance to improve the modeling efficiency and accuracy of large-scale power system. Most of the existing layout algorithms are confined to the research of cross points and layout uniformity, while they don’t consider the actual relative position between nodes, resulting in extremely unstable layout results at every turn. Therefore, a spring-electronic model based hierarchical layout method is proposed for automatic transformation of large-scale electromechanical-electromagnetic transient simulation model. The approach considers the actual relative position between nodes, realizes the hierarchical layout of networks with different voltage levels, and avoids the problem of large difference in layout results of traditional methods. It can not only be used to draw electromechanical transient geographical wiring diagram, but also provide nodes coordinate information for the generation of large-scale electromagnetic transient simulation model. The effectiveness of the proposed approach is verified through case testing and analysis of the Western System Coordinating Council(WSCC) 3-generator 9-bus system, the New England 10-generator 39-bus system, and a regional power system.
