摘　　要：基于E格式电网结构数据和特定时间断面下主变、线路的负载数据,生成了配电网功率流拓扑,在此基础之上设计了用于辨识配电网薄弱环节的快速算法,对电网中的设备过载、变电站单主变运行、变电站失去母线等薄弱环节进行识别,提供了相关运行建议,并生成电网预警通知书供运行人员参考;采用SZ系统算例,对上述方法的有效性进行了验证。Topological power flow was set up based on the power system model described by E format file,along with load flow data of transformers and lines at certain moment. A fast algorithm based on topological power flow for identifying weaknesses of distribution system was developed to discover the overloaded apparatus,the outage of bus bar or transformer in substation,etc. The alarming notification was then produced to provide suggestions on system operation.Test results of Suzhou power system validated the effectiveness of the proposed algorithm.
