摘要

配电网中的智能终端(STU)要实现分布式控制需要知道馈线实时拓扑。依赖配电自动化主站给STU下发馈线实时拓扑的方式灵活性差

不利于实现自治性控制系统;为每一个STU人工配置关联馈线全局静态拓扑

通过STU获取关联馈线域内开关的实时状态信息建立馈线实时拓扑的方式配置工作量大;提出了一种STU自主识别馈线拓扑的方法

为每个STU配置局部拓扑信息

由STU通过逐级查询的方式获取馈线实时拓扑。以广域闭锁分布式电流保护为例

在有源配电网静态模拟系统上搭建了测试系统

证明了所提馈线拓扑识别方法的有效性。

Abstract

The real-time topology of the feeder is needed by the smart terminal unit (STU) to implement distributed control in a distribution network. The way the master station downloads the feeder topology information to STUs is hardly flexible in realizing autonomy. Another way is to manually configure each STU with the whole range of related feeders’ topology

but for the STU to establish real-time feeder topology after obtaining the real-time status information of switches in the related feeders

astronomical amount of configuration work needs to be done. An identification method for feeder topology based on STU successive polling is proposed. After configuring each STU with its local topology information

real-time feeder topology is obtained through STU successive polling. A distributed over-current protection using the wide area blocking signals system is set up and tested on the platform of the static simulation system for the active distribution network to show the effectiveness of the proposed feeder topology recognition method. This work is supported by National High Technology Research and Development Program of China (863 Program) (No. 2012AA050213).
