提出一种确定和辨识拓扑错误的方法。提出了基于新息向量的新息图,在其上可以根据支路扩展新息向量和估计潮流确定拓扑错误,而且还可以根据不良回路和差别向量对出现在拓扑错误支路上或其他支路上的坏数据进行辨识。文中给出了IEEE—30 和IEEE—118 节点系统的计算实例 A method of identifying and identifying topology errors is proposed. A new interest rate graph based on the new interest vector is proposed, on which the topology error can be determined according to the branch expansion interest vector and the estimated power flow, and the topology error can also be identified according to the bad loop and the difference vector on the branch with the wrong topology or other branches Bad data identification. The paper gives the calculation examples of IEEE-30 and IEEE-118 node systems
