摘要
新息图是根据测量向量和预报向量之差的新息向量推出来的 ,是新息向量和图论的结合。新息图对于识别坏数据和拓扑错误很有价值。现有的新息向量未考虑元素间有物理定律约束的内在联系。文中定义了反映新息向量元素间内在联系的新息图 ,给出了计算实例 。
The innovation graph is deduced from the innovation vector that is formed by the difference of measurement vectorand predictive vector. The method is the combination of innovation vector and graph theory. The innovation graph is valuableto identify bad data and topology errors. The present innovation vector does not reflect the inner relationship among theelements of the stipulations of an agreement innovation vector. In this paper the definition of the innovation graph refjectingtheir inner relationship is given and the artificial intelligent characteristics are described from the views of the epistemologyand the methodology.This project is supported by the State Key Laboratory of Power System in Tsinghua University of China.
