摘　　要：为解决矿区配电网非健全信息情况下故障指示器故障判定问题,提出了最小故障判定区域的概念,基于最小故障判定区域概念建立了故障指示器故障判定数学模型,以该数学模型为基础提出了一种基于最差原则的故障指示器故障判定方法。该方法通过最差原则对短路故障信号及接地故障信号进行辨识与修正,一定程度上解决了故障信号漏报和误报等非健全信息情况下的故障判定问题。运行实例证明了所提方法的实用性和准确性。In order to solve problem of fault diagnosis of fault indicator for distribution power network in mining area in imperfect information,the concept of the minimum fault diagnosis area was put forward.The fault diagnosis mathematical model of fault indicator based on the concept of the minimum fault diagnosis area was proposed,and a fault diagnosis method of fault indicator based on the worst principle and the mathematical model was proposed.The method recognizes and corrects short circuit fault signals and the fault grounding signal through the worst principle,and solves fault diagnosis problem such as false negatives and false positives of fault signal in imperfect information.The running example proves the practicability and correctness of the method.
