Distribution network feeder automation,as an effective measure to improve the reliability of power supply,is an important part of the China's "12th Five-Year Plan" on the construction of smart grid.Focusing on an analysis and research on the strategies of automatic power supply by transforming the local feeder automation devices which is apphed universally in China,this paper points out the deficiencies in the design of the operation strategy and the dangers posed to the power system and its operation management.Furthermore,using the power grid of Zhongshan Power Supply Bureau as a typical example,a solution is proposed that devices of contact switch FA can be reformed on its operation technology for reliable automatic power supply transforming in the distribution ring network,which provides a new reference and selection for the study of the automation of distribution network feeders on its further application and development.%配网馈线自动化是提高供电可靠性的有效措施,是智能电网建设的重要一环.对目前普遍应用的就地型馈线自动化装置自动转供电的策略进行分析、研究,指出该动作策略设计上的不足及可能给电力系统及运行管理带来的危险,并以中山供电局作为典型案例,提出了对联络开关FA装置进行技术改造等以实现可靠的配电环网自动转供电目标的解决方案,为配网馈线自动化的深层应用及开发提供参考.
