摘要
对于一个给定的电力系统和量测系统,量测量之间的线性相关关系可以用拓扑方法确定。本文推导了具有这种相关关系的量测量之间的线性表达式,并提出一种新的多不良数据检测方法。在电力系统状态估计中,通过相关量测量之间的直接校核,使检测相关多不良数据的可靠程度大大提高。
The linear dependence relations among the measurements of a measuring system can be determined by topological method. This paper derives some linear equations the-measurements ought to satisfy. Based on which, a new detection method for bad data is presented, which detects multiple bad data by checking up whether the real time measuring-values satisfy the equations or not. The method has the nature of local testing and the function of modifying bad data. The availability of the method has been proven by many tests.
