摘要：

A combinatorial approach to deal with qualitative problems related to power system state estimation is proposed. The discussed techniques share the same theoretical background which also underlies a previously proposed method for observability analysis. The combinatorial framework is presented and further exploited to devise a fast method for identification of single critical measurements. This method is then extended to allow the determination of critical measurement sets. The interest in investigating these questions lies in the fact that, when contaminated by gross errors, critical measurements are undetectable, whereas measurements in critical sets are unidentifiable. The performance of the proposed combinatorial methods is appraised by means of several tests, using the IEEE-14 and 30 bus systems and two realistic systems of Brazilian utilities. © 1990 IEEE
