| 摘要: |
| 分析了现阶段配电网自动化系统结构及配电网馈线自动化技术。说明了实施馈线自动化的技术原则．将故障诊断流程归纳为以配电终端为基础的故障检测、以配电网子站为中心的区域控制和以主站为管理中心的高层全局控制．并提供了线路相间短路及单相接地故障的识别策略。阐述了馈线自动化处理过程，包括馈线终端装置（FTU）／开闭所终端装置（DTU）、配电网子站、主站以及架空线路的故障处理，将故障处理时间划分为永久性故障判别时间、子站故障信息收集时间、子站故障定位时间、子站执行故障隔离时间、主站处理时间、主站执行故障恢复时间。最后描述了配电网自动化的发展方向． |

| Abstract: |
| Current configuration of distribution automation system and its feeder automation technology are analyzed.The technical rules to implement feeder automation are demonstrated.The fault diagnosis flow consists of the fault detection with distribution terminal as basis,the area control with distribution substation as control center and the global control with main station as the management center.The identification strategies for inter-phase short circuit fault and single-phase grounding fault are provided.The fault-processing course of feeder automation is expounded,including FTU(Feeder Terminal Unit) / DTU(Distribution Terminal Unit),distribution substation,main station and overhead lines.The fault processing time is divided into six parts:judgment time of permanent fault,substation fault information collection time,substation fault locating time,main station processing time and main station fault recovery time.The development trend of distribution automation is described as well. |
