| 摘 要： | 残差污染的存在对正确检测与辨识坏数据的危害很大，而用一种统一的方法，根据量测残差识别出残差污染，从而准确地检测了与辨识坏数据一直非常困难。文中基于残差符号信息研究状态估计中的残差污染问题，了基于残差灵敏度矩阵和残差符号判断存在严重的残差污染的可能性，在此基础上，提出了利用残差符号信息识别严重的残差污染的方法，用简单的图示直观地描述了这一方法，ＩＥＥＥ３０节点系统上的试验证实了所提出的方法提出了检测

| Abstract: | The existence of residual contamination is harmful to detecting and identifying bad data in power system state estimation.It is difficult to identify various residual contamination using the same method according to the measurement residual. Based on residual sensitivity m atrix and signs of residuals,this paper presents a new method to determine the possibility of existence of the worst residual contamination. Then a new method is presented to identify the worst residual contamination based on signs of measurement residuals.Test on IEEE3 0 bus system confirms that the proposed method improves the veracity of detecting and identifying bad data. |
