摘　　要：自适应重合闸技术具有传统重合闸技术所不具有的优势。针对电力系统发生单相接地、两相接地、两相相间故障时的电压特点,应用电压判据正确区分了瞬时性故障和永久性故障。还介绍了虚拟仪器的概念,并以图形化编程软件Lab VIEW为软件开发平台,开发了虚拟重合闸实验平台。该实验平台具有界面友好、操作简单等优点,可将其用于自适应重合闸新方法的测试研究和实验教学中,具有实际意义。The self-adaptive reclosure offers many advantages over the conventional reclosure.The characteristics of the post-fault voltage of the single-phase grounding fault,the two-phase grounding fault,and the phase-to-phase fault are analyzed and were used for discrimination of the transient fault and the permanent fault.The concept of the virtual instrument is presented,and the LabVIEW graphical programming environment was used to develop the virtual reclosing system with the advantages of friendly interface and simple operation.
