配电自动化系统中开闭所RTU的设计方案

在充分调研配电自动化技术的发展和用户要求的基础上,根据开闭所的结构特点和运行方式,确定了开闭所RTU的功能需求,以及开闭所主控单元的逻辑功能.利用LonWorks现场总线技术,将开闭所RTU进行分散分布式安装.现场运行表明,该方案在短时间内实现了开闭所的故障检测、隔离,以及快速恢复健康线路的供电.;The development of DA technology and user’s demand is studied． According to the structure and running style of switch substation，RTU function and logical function of main control unit are determined and the design project，which adopts distributed installation style and LonWorks field bus，is put forward． Practical application shows that the design project can realize fault detection and isolation and resume power supply of switch substation promptly
