【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]:In order to realize distributed control, intelligent terminal (STU) in distribution network needs to know the real-time topology of feeder.It is difficult to realize autonomous control system by relying on distribution automation master station to transmit feeder real-time topology to STU, and to manually configure the global static topology of associated feeder for each STU.The configuration of the real-time topology of the feeder is heavy in the way of obtaining the real-time state information of the switch in the relative feeder domain by STU, and a method of identifying the feeder topology independently by STU is proposed, which can configure the local topology information for each STU.The real-time topology of feeder is obtained by STU by step-by-step query.Taking wide-area latch-up distributed current protection as an example, a test system is built on the static simulation system of active distribution network, which proves the effectiveness of the proposed method of feeder topology identification.
