摘　　要：针对遥信错误辨识问题,提出了一种基于规则和混合法的遥信错误辨识方法。首先制定规则剔除简单的遥信错误;对于无法通过简单规则辨识的遥信,提出采用转移潮流法和新息图法相结合的拓扑错误混合辨识方法进行辨识,该混合辨识方法具有如下特点:以前一断面的状态估计结果作为基态,避免转移潮流法在实际工程中基态选择的困难;通过新息图法中的修正预估比判断拓扑可疑支路,避免转移潮流法中用转移潮流判定拓扑可疑支路可能导致的误判;引入转移潮流法中注入功率对转移潮流的影响量,避免采用新息图法出现较大负荷预测误差产生负荷突变问题。最后,以算例证明了所述方法的有效性。For identification of remote signal error,this paper presents a novel method based on rule method and hybrid method.Firstly,simple remote signal errors are identified by defining rules.For the remote signal errors that resist being identified through rules,a synthetic method based on the power flow transfer approach and innovation graph approach is proposed.The characteristics of the synthetic method lie in using previous state estimation results as the baseline to bypass the difficulty in baseline selection for the power flow transfer approach.With the modified pre-estimated ratio as criterion for topology error,the misidentification of topology error results from error identification criteria in the flow transfer approach is avoided.The effects on flow transfer of power injections are introduced from flow transfer approach to solve the sudden load change problem in the innovation graph approach.Test examples show the effectiveness of the proposed method.
