境外地铁供变电数智化保护及监控应用研究

分析了以色列红线地铁外电源及供电系统中压供电网络技术特征,基于通信技术和交换机技术,实施了供变电综合数智化网络设计及继电保护GOOSE网络设计,针对工程实施过程中出现的数据干扰、网络风暴等技术挑战,提出了切实可行的解决方案并在实际调试过程中得到了技术验证,对开展轨道交通供变电工程网络数智化设计有一定参考意义。

The paper analyzes the technical characteristics of the medium-voltage network of the external power supply and power supply system of the Red Line of Light Rail in Israel.According to the communication technology and switch technology,the comprehensive digitalized and intellectualized network design of the power supply system and the design of the relay protection GOOSE network are implemented.For technical challenges such as data interference and network storms,practical solutions are proposed and technically verified in the actual commissioning test process,it has certain reference for the development of digitalized and intellectualized network design of projects of rail transit power supply and substations.
