摘要
小电流接地系统发生单相接地故障时,各种电气量表现出不同于正常工况时的特征,可根据各种电气量的特征对系统运行状况进行模式识别,文中利用分类支持向量机对小电流接地系统运行状况进行模式识别,以确定接地故障线路或母线。测试结果表明,该方法有效、准确,具有一定的实用价值。
In Peterson-coil-grounding system (PCGS), the electric parameters in grounding fault have different electric characteristics, and the working situation of PCGS can be recognized by electric parameters of system. In this paper, support vector machines for classification (SVMC)are used to recognize the working situation of PCGS and to detect the fault line or bus. Simulation results are also given.
