基于集中式配电自动化终端的故障自愈技术综合应用

Comprehensive Application of Fault Self-Healing Technology Based on Centralized Distribution Automation Terminal

通过深入开展公用配电电网自愈故障控制系统技术应用研究,现场监控设备自动更换、后台过程数据处理质量控制提升和监控技术平台集成推广应用等新手段,提升试点示范区公用配电网系统运行安全管理监控技术水平,提高配网供电系统可靠性,缩短配网故障检测隔离处理时间。通过智能配电网故障检测、定位与隔离技术,分别针对架空和电缆线路提出了配电网故障定位、隔离和供电恢复方案,重点提出了主站与就地型馈线自动化相协调的自愈控制方案,解决传统就地型馈线自动化无法可靠实现负荷转供的问题。

Through in-depth research on the application of self-healing fault control system technology in public distribution grids,new methods such as automatic replacement of on-site monitoring equipment,improvement of background process data processing quality control and monitoring technology platform integration and application,promote public power distribution in pilot demonstration areas Network system operation safety management and monitoring technology level,improve the reliability of the distribution network power supply system,and shorten the time for fault detection and isolation processing of the distribution network.Through the intelligent distribution network fault detection,location and isolation technology,the distribution network fault location,isolation and power supply restoration schemes are respectively proposed for the overhead and cable lines,and the self-healing control coordinated by the master station and the local feeder automation is mainly proposed.The solution solves the problem that traditional on-site feeder automation cannot reliably realize load transfer.
