Distributed control has good real-time performance and can better meet the control requirements of active distribution networks with a large number of distributed generations. Some distributed applications require real-time feeder topology to achieve control. In this paper, the demand for distributed control applications for feeder real-time topology is analyzed. Based on IEC 61850 modeling method, a new cell topology logic node and a new topology slice node are built to express feeder topology. Using the topology information of smart terminal unit (STU) configuration and the current status information of switchgear, based on the depth-first search, the feeder real-time topology identification can be realized, which meets the application requirements of distributed control. The study case verified the effectiveness of the method.

基于IEC 61850逻辑节点的配电网拓扑识别

分布式控制具有良好的实时性能，可以更好地满足具有大量分布式发电的有源配电网的控制要求。一些分布式应用程序需要实时馈线拓扑以实现控制。本文分析了馈线实时拓扑对分布式控制应用的需求。基于IEC 61850建模方法，构建了新的单元拓扑逻辑节点和新的拓扑切片节点来表示馈线拓扑。利用智能终端单元（STU）配置的拓扑信息和开关柜的当前状态信息，基于深度优先搜索，可以实现馈线实时拓扑识别，满足分布式控制的应用需求。研究案例验证了该方法的有效性。
