摘　　要：提出了用新息图法辨识母线拓扑错误的方法。先在网络计算模型上 ,根据支路新息找出可疑母线 ,然后对可疑母线采用物理模型表示 ,引入零阻抗支路模型 ,用新息图法辨识断路器的状态 ,确定发生母线拓扑错误的位置。文中用IEEE - 5节点系统描述了此方法 ,给出了IEEE -This paper proposes an innovation graph method for the location and identification of the substation bus topology errors. Firstly bus/branch network model is used, and the suspect buses at which split may occur are find out in terms of the branch innovation vector. Then the suspect buses are modeled in detail using a bus section/circuit breaker network model. The circuit breakers are modeled in zero impedance branches. Lastly the method identifies the status of the circuit breakers and makes sure of the location where the buses split using the innovation graph approach. Results on the IEEE-5 bus system are used to illustrate the method. The simulation on the IEEE-30 bus system testifies validity of the approach.
