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。
Adaptive reclosing technology with the traditional reclosing technology does not have the advantages. Aiming at the voltage characteristics of single-phase grounding, two-phase grounding and two-phase fault in power system, the instantaneous fault and permanent fault are correctly distinguished by voltage criterion. Also introduced the concept of virtual instrument, and graphical programming software Lab VIEW as a software development platform, developed a virtual reclosing experimental platform. The experimental platform has the advantages of friendly interface and simple operation, which can be used in the test research and experimental teaching of the new method of adaptive reclosing, which is of practical significance.
