摘　　要：基于社会发展对供电可靠性提出的挑战,并结合"新工科"教育改革背景,该文针对电气专业设计了一种配电环网短路故障自同步与快速自愈技术实验系统。该系统立足于闭环运行的配电网络,利用支持点对点通信与分布式智能控制的配电终端(feeder terminal unit,FTU),基于故障信号自同步与差动保护技术,自动快速隔离短路故障区段,实现非故障区段快速自愈功能;实验结果证明了FTU自同步与故障自愈性能,且实践效果良好。该实验平台具有综合、开放与创新的特点,是助力落实本专业"新工科"教育改革的有效手段之一。Based on the challenge of social development to power supply reliability and in combination with the background of "new engineering" education reform, an experimental system of short circuit self-synchronization and fault self-healing technology for distribution network with closed-loop operation is designed for electrical specialty. This system is based on the closed-loop distribution network and uses the feeder terminal unit which supports point-to-point communication and distributed intelligent control. Based on the technology of fault signal self-synchronization and differential protection, the short-circuit fault section can be isolated automatically and quickly to realize the self-healing function of non-fault section. The experimental results have proved the FTU self-synchronization and fault self-healing performance, and the practice effect is good. The experimental platform is comprehensive, open and innovative, and is one of the effective means to implement the "new engineering" education reform in this specialty.
