摘　　要：介绍了目前已有的分布式母线保护方案,并将环网无主机式结构的就地化分布式母线保护与传统的集中式母线保护装置,从继电保护的四性(可靠性、速动性、选择性、灵敏性)等方面进行了对比分析。通过分析和试验发现,就地化分布式母线保护在可靠性与速动性方面比传统母线保护存在优势,选择性和灵敏性上两者性能相同。同时,就地化分布式母线保护在安装和运行维护方面也有一定的优势。通过各项性能的对比,认为就地化分布式母线保护有潜力取代传统集中式母线保护,是未来新一代智能变电站母线保护的发展方向。This paper introduced existing distributed busbar protection plans,and compared localized distributed busbar protection and traditional centralized busbar protection based on reliability,speed,selectivity and sensitivity. By analysis and test,these two methods have same performance of selectivity and sensitivity. Local distributed busbarprotection is more reliable,fasterand more convenient of installation and maintenance than traditional busbar protection. Through the comparison of various performance,distributed bus protection has the potential to replace the traditional centralized bus protection. Which is the developing direction of new generation intelligent substation busbar protection.
