| 摘要: |
| 提出一种基于道路-回路方程的拓扑错误辨识方法。利用网络拓扑约束与基尔霍夫定律，并借助相量测量单元（PMU）提供的同步电气量信息，建立道路-回路方程，计算支路电流。在此基础上，考虑各种拓扑错误及不良数据并存的情况，根据计算值与量测值间的差值，对拓扑信息及支路电流量测值进行校验。IEEE 9与IEEE 39节点系统仿真结果表明所提方法具有较好的适应性、可靠性及容错能力。 |

| Abstract: |
| A method of topology error identification based on the road-loop equation is proposed，which uses the constraints of network topology and Kirchhoff laws to establish the road-loop equation and calculate the branch current according to the synchronous electrical measurements provided by PMU（Phasor Measurement Unit）. With the consideration of various topological errors and bad data，the topological information and the branch current measurements are verified according to the difference between derived and measured values. The simulative results of IEEE 9-bus system and IEEE 39-bus system show that，the proposed method has good adaptability，reliability and fault-tolerance capability. |
